Abstract

The problem of urban drainage has become more serious with the rapid development of urban construction. The idea of combining geographic information system (GIS) technology with flood control in solving the urban drainage problem has received increasing attention. The idea and process of GIS as the key technology in vertical planning were analyzed in this study based on the GIS technology characteristics. This paper presents the new idea of integrating flood control and drainage mode into vertical planning and the optimization method in vertical planning. Taking the vertical planning of the north shore of Xiaoqing River in Ji'nan as an example, the model of the present scenario and the corresponding terrain model of the different flood control drainage standards were established. The standard model of the flood control and drainage of Xiaoqing River was determined through comparison. The relationship between vertical planning, flood control, and drainage mode was analyzed and optimized on the basis of the practical engineering results. Improving the optimization measures can result in the good convergence of vertical planning and drainage content, which is conducive to the development of urban flood control.

Abstract

Flood season in our country is characterized by frequent heavy rains, and flood problems are becoming increasingly serious. The uneven distribution of water resources causes conflicts in the occurrence of floods and droughts. Implementing effective flood control planning and solving drought and flood disasters are the research highlights of relevant institutions both domestic and abroad. This study develops a multiscale method of urban flood control planning based on microcirculation. A microcirculation water ecosystem, which consists of six elements, namely, collecting, interacting, precipitating, reserving, storing, and purifying, is introduced. This study investigates precipitation; peak shaving; recycle mode of filtration at the macro level in different regions; “hierarchy” in rainwater ecosystems in rain parks, heavy rain garden parks, and wetland parks at the meso level; and the concept of zero-emission rain in residential areas and roads at the micro level. Finally, this study analyzes a rain garden and its domestic application. A conclusion is drawn that the flood control planning model based on microcirculation can effectively reduce rain runoff. Empirical measurement proves that the proposed multiscale model for city flood control planning based on microcirculation promotes flood control and effectively reduces the occurrence of droughts and floods.

Abstract

Under the background of rapid urbanization, all kinds of urban water problems have gradually come into being: local flooding frequently happens, water environment is deteriorated, water-supply is in tension, etc. Meanwhile, with rapid development of higher education in China, campus area and scale are gradually expanding, but traditional campus construction has many drawbacks. In order to promote sponge campus planning and construction of universities in hilly areas and provide demonstration windows for sponge city construction, based on deficiencies of campus construction of Hunan City University in the aspect of water resource utilization, we used ArcGis spatial analysis method, simulation method and comparative analysis method on Storm Water Management Model (SWMM) to establish sponge campus construction indexes, content system and optimal design strategies with objectives of campus water safety, water environment and water resource utilization. Results indicate that: difference between sponge campus planning and traditional campus planning mainly lies in rainfall management. We combed the design process of sponge campus planning in hilly areas from the perspective of rainfall management, and simulated the process of sponge facilities controlling the rainfall in the campus via computer model to verify reasonability of sponge facility planning and select the optimal planning and construction plan. This study has defined design process of sponge campus planning in hilly areas to a certain degree and provided a research basis for sponge campus planning and construction of universities, setting up a typical example and driving effects on solving urban local flooding problem and rainfall resource utilization in hilly areas.

Abstract

This study examines the causes of flood disasters in Jianghan Plain, China and provides practical solutions to mitigate them. Results from this study indicate that both historical archives and more recent recorded data point to an increasing frequency in flood disasters since 1961. Furthermore, damage and losses from flood disasters have also increased significantly in the region. By analyzing the physical geographic factors and human activities, this study found that the main causative factors contributing to increasing flood disasters are landform/topography, climate elements, reduced drainage capacity of rivers in contrast to increased flood discharge, and human activities. Finally, the study examines various practical solutions to mitigate flood disasters in the Jianghan Plain.

Abstract

Purpose

The purpose of this research is to provide a theoretical and practical theory and application that provides understanding and means to manage complex infrastructures.

Design/methodology/approach

In this research, complexity, nonlinear, noncontinuous effects and aleatoric and data unknowns are bypassed by directly addressing systems' responses. Graph theory, statistics and digital signal processing (DSP) tools are applied within a theoretical framework of the theory of faults (ToF). Motivational complex infrastructure systems (CISs) are difficult to model. Data are often missing or erroneous, changes are not well documented and processes are not well understood. On top of it, under complexity, stalwart analytical tools have limited predictive power. The aleatoric risk, such as rain and risk cascading from interconnected infrastructures, is unpredictable. Mitigation, response and recovery efforts are adversely affected.

Findings

The theory and application are presented and demonstrated by a step-by-step development of an application to a municipal drainage system. A database of faults is analyzed to produce system statistics, spatio-temporal morphology, behavior and traits. The gained understanding is compared to the physical system's design and to its modus operandi. Implications for design and maintenance are inferred; DSP tools to manage the system in real time are developed.

Research limitations/implications

Sociological systems are interest driven. Some events are intentionally created and directed to the benefit and detriment of the opposing parties in a project. Those events may be explained and possibly predicted by understanding power plays, not power functions. For those events, sociological game theories provide better explanatory value than mathematical gain theories.

Practical implications

The theory provides a thematic network for modeling and resolving aleatoric uncertainty in engineering and sociological systems. The framework may be elaborated to fields such as energy, healthcare and critical infrastructure.

Social implications

ToF provides a framework for the modeling and prediction of faults generated by inherent aleatoric uncertainties in social and technological systems. Therefore, the framework and theory lay the basis for automated monitoring and control of aleatoric uncertainties such as mechanical failures and human errors and the development of mitigation systems.

Originality/value

The contribution of this research is in the provision of an explicatory theory and a management paradigm for complex systems. This theory is applicable to a wide variety of fields from facilities and construction project management to maintenance and from academic studies to commercial use.

Abstract

Purpose

Flooding is an emerging problem in Ho Chi Minh City (HCMC), Vietnam, and is fast becoming a major barrier to its ongoing development. While flooding is presently of nuisance value, there is a growing concern that a combination of rapid urban expansion and climate changes will significantly exacerbate the problem. There has been a trend of population being rapidly accommodated in new urban areas, which are considered highly vulnerable to floods, while the development strategy by the local government still attracts more property investments into the three new districts on the right side of Saigon River. This paper aims to discuss the increase in the number of residences vulnerable to flooding, to underline the need for more appropriate future spatial development. For the vision, an application of compact and resilient theories to strategic planning and management of this city is proposed to reduce vulnerability. This paper also highlights the need to better understand growing vulnerability to floods related to urban expansion over low-lying former wetlands and the more important role of planning spatial development accompanied with transportation investment which can contribute to flooding resilience.

Design/methodology/approach

This research uses combined-methods geographical information system (GIS) analysis based on secondary data of flood records, population distributions, property development (with the details of 270 housing projects compiled as part of this research) and flooding simulation. This allows an integrated approach to the theories of urban resilience and compactness to discuss the implication of spatial planning and management in relevance to flooding vulnerability.

Findings

The flooding situation in HCMC is an evidence of inappropriate urban expansion leading to increase in flooding vulnerability. Although climate change impacts are obvious, the rapid population growth and associated accommodation development are believed to be the key cause which has not been solved. It was found that the three new emerging districts (District 2, 9 and ThuDuc) are highly vulnerable to floods, but the local government still implements the plan for attracted investments in housing without an integrated flooding management. This is also in line with the development pattern of many coastal cities in Southeast Asia, as economic development can be seen as a driving factor.

Research limitations/implications

The data of property development are diversified from different sources which have been compiled by this research from the basic map of housing investments from a governmental body, the Department of Construction. The number of projects was limited to 270 per over 500 projects, but this still sufficiently supports the evidence of increasing accommodation in new development districts.

Practical implications

HCMC needs neater strategies for planning and management of spatial development to minimize the areas vulnerable to floods: creating more compact spaces in the central areas (Zone 1) protected by the current flooding management system, and offering more resilient spaces for new development areas (Zone 2), by improving the resilience of transportation system. Nevertheless, a similar combination of compact spaces and resilient spaces in emerging districts could also be incorporated into the existing developments, and sustainable drainage systems or underground water storage in buildings could also be included in the design to compensate for the former wetlands lost.

Social implications

This paper highlights the need to better understand growing vulnerability to floods related to urban expansion over low-lying former wetlands and emphasizes the more important role of planning spatial development accompanied with transportation investment which can contribute to flooding resilience. Coastal cities in southeast countries need to utilize the former-land, whereas feasibility of new land for urban expansion needs to be thoroughly considered under risk of natural disasters.

Originality/value

A combination of compact spaces with improved urban resilience is an alternative approach to decrease the flooding risk beyond that of traditional resistant systems and underlines the increasingly important role of urban planning and management to combat the future impacts of floods.

Abstract

Purpose

The purpose of this paper is to re-frame planning decision-making to address risks of flooding and to increase community resilience. Rapid urbanisation, fragmented governance and recurrent flooding complicate resolution of DKI Jakarta’s chronic housing shortage. Failure to effectively implement planning decision-making processes poses potential human rights violations. Contemporary planning policy requires the relocation of households living in floodplains within 15 m of DKI Jakarta’s main watercourses, further constraining land availability and potentially requiring increased densification.

Design/methodology/approach

This paper presents a preliminary scoping study for a technologically enhanced participatory planning method, incorporating synthesis of existing information on urbanisation, governance and flood risk management in Jakarta.

Findings

Responsibility for flood risk management in DKI Jakarta is fragmented both within and across administrative boundaries. Decision-making is further complicated by: limited availability of land use data; uncertainty as to the delineated extent of watercourses, floodplains and flood modelling; unclear risk and liability for infrastructure investments; and technical literacy of both public and government participants.

Practical implications

This research provides information to facilitate consultation with government entities tasked with re-framing planning processes to increase public participation.

Social implications

Potential increased opportunities for collaborative decision-making and consequent reduction in risk exposure amongst DKI Jakarta’s most vulnerable populations can help to address issues of social justice.

Originality/value

This paper synthesises information from a range of sources not available in English, and offers insights into a complex system of governance and modes for improving decision-making.

Abstract

In recent years, due to fast growth of Kabul city in Afghanistan, newest construction has been taking place in unplanned ways and entailed illegal squatting on land and mountains. Such unplanned urban expansion, without any type of urban infrastructure and insufficient drainage systems, has created many problems including an increasing number of urban floods. Recent reports show that the number of female victims is higher than that of males affected by floods. First, this chapter highlights the country overview of the disaster and vulnerability, and then particularly focus on the vulnerability factors of urban women who are affected by floods and living in Kabul city. Data for this study were obtained through focus group discussions with urban women, and men and face-to-face interviews with governmental and non-governmental organizations (GOs-NGOs) at the local as well as national levels in Afghanistan. Interpretive Structural Modelling (ISM) was used to map the relationship among factors, and to stratify factors according to their importance. Findings show that the lack of education on disaster management and the lack of protective measures play an important role in increasing women’s vulnerability during disasters. Furthermore, the study finds that cultural issues represent a dominant vulnerability factor which affect women. The comparative results show that the women affected by the cultural norms during the flood are less important than the post-disaster. The study also found that the perception regarding these cultural norms and how they affect women’s behaviour during disasters differs between men and women. This chapter concluded some policy recommendations towards resilient livelihoods.

Abstract

Purpose

This paper presents a case study of the response of a pharmaceutical goods manufacturer to an unexpected disruptive event. Following a period of heavy rainfall, a small town within the UK was quickly overwhelmed by localised flash flooding. The sudden rise in ground water overwhelmed local drainage systems and caused flooding in several areas of the town. One of the impacted areas included the manufacturing facilities of a pharmaceutical goods producer. This case study explores the subsequent response of the organisation to the event.

Design/methodology/approach

Based on direct interviews and supporting documentation, this case study analyses the organisation's response and recovery activities in the face of escalating impacts. Drawing on identified theory, specific attention is placed on characterising severe events and the challenges of coordinating response activities.

Findings

Drawing on the evidence of this case study, this paper highlights the identified features of an effective response within escalating events. Without this response, events such as those experienced by the case study organisation carry the distinct possibility of developing into large scale disruptions. This study highlights the importance of established channels of authority and the ability to identify and contain impacts.

Originality/value

This paper outlines some of the key considerations and operational priorities within response activities. These priorities support the effective identification and resolution of disruptive events and their associated impacts.
