The purpose of this paper is to assess the scale of changes in the distribution of water and their influence on the components of the hydrological balance in two lake catchments situated in the Leczna-Wlodawa Lake District.

In order to estimate the scale of man-made modification of water distribution an analysis of published cartographic materials was used. The maps cover time-scale of over 150 years. The analysis was completed by territorial research carried out during water years 2007-2009. The elements of water balance equation were calculated on the basis of daily water levels, discharge, precipitations and lake volumes. Evaporation was calculated as the difference of balance gains and losses (runoff deficit).

The study has shown high permanent human pressure on lake-catchment systems under study, since the 50 of the nineteenth century. Naturally drainless lakes were connected to the system of surface runoff, which modified radically directions and pace of water circulation. The most pronounced hydrologic changes of the lake-catchment systems under study occurred in the 60 of the twentieth century. Human pressure on water conditions resulted in changes of water balance elements relation (increased surface inflow and outflow).

In the ecosystems with zonal watersheds, even slight modification of water distribution may lead to radical changes in the structure of lake-catchment systems’ water balance. The paper is first in polish literature that documents major water divide translocation, as well as bifurcation in the drainage area of the highest cascade lake. Man-made modifications cause natural ecosystems degradation, especially in the areas built with peat-bogs.

This paper sets out describe the creation of sustainable urban planning concepts based on optimized urban landscape functioning. It gives an account of the formation and transformation processes of natural and artificial streaming structures.

The paper examines the present‐day approaches to the environmental assessment and zoning of urban territories. This was achieved by creating the conceptual methodological basis for the assessment and classification of urban landscapes.

Based on an analysis of the urban planning development of the Moscow agglomeration, principles have been proposed for the shaping of sustainable urban planning structures – landscape planning that can be applied to the management of the territorial growth of large cities and urban agglomerations. First, the shaping and reconstruction of the city structure, including the structure of land management, as well as the mutual arrangement of functional areas, should be based on the need to preserve the axes – the lines and planes of mass, energy and information transfer of landscapes of various orders. Second, the order of preserved landscape axes depends on the organisational complexity of a territory. Third, assessment of the sustainability of the structure of a city and agglomeration should be based on the criteria of river systems along their borders, such as the quantity and composition of water, its temperature, retention of the annual functioning cycle and biodiversity. Finally, urban planning control regimes should be established across the entire city and they should be determined by the position of the territory in the city's landscape structure.

This work will provide a better understanding of integrated environmental systems to enable development of best management practices in the city of Moscow.

The term ‘strategy’ is one of the most frequently used terms in business, and its application in marketing is particularly common. Company strategy, market strategy, marketing strategy, sales strategy, promotion strategy, distribution strategy, low pricing strategy – it would take a long time to list all of them. Although this term is so commonly in use, its definition is not as straightforward and it can be interpreted in different ways. In comparison with tactical decisions, strategy is much more significant for an organisation as it brings long-lasting consequences. It is implemented by higher level managers on a regular basis, and it is based on external, often subjective information, so decisions – especially at the time they are made – are difficult to evaluate.

Taking into consideration the fact that strategy refers to a long-term rather than a short-term period, strategic decisions serve as the basis for undertaking operational activities. However, marketing refers to the market and the competition. It is possible to claim that marketing strategy is trying to find an answer to the question to which path an organisation should follow in order to achieve its goals and objectives. If, for example, a company has a goal to generate a profit of PLN 1 million by selling 100,000 pieces of a product, the market strategy should answer at least the following two questions:

1. Who will be our target group, for example, who will purchase the 100,000 pieces of the product?

2. Why is it us from whom a potential buyer should purchase the product?

Who will be our target group, for example, who will purchase the 100,000 pieces of the product?

Why is it us from whom a potential buyer should purchase the product?

The target market will be defined if a reply to the first question is provided. The second question identifies the foundations of competitive advantage. These two issues, that is, target market and competitive advantage are the strategic marketing issues. You cannot change your target group unexpectedly while competitive advantage is the basis for changing decisions regarding prices, promotions and sales.

This chapter describes the measures of marketing activities which refer to strategic aspects and testify a company’s market position – the measures of the performance of target groups and competitive advantage. Readers’ attention should be also focused on the indices that are less popular in Poland and, therefore, may be underestimated. It seems that some of them, for example, the index of marketing resources allocation and the marketing risk index, provide a lot of valuable information and, at the same time, make it possible to show the value of marketing investments. Their wider use in the near future is only a matter of time.

To provide water utilities operating under rationing conditions with some insight into issues related to managing non‐revenue water (NRW).

Reviews general theories associated with pressure, surges and water leakage, and compares them with real data in a rationed water distribution system.

In water networks there is a strong relationship between rationing hours and rationing surge pressures and NRW levels. These relationships mean that traditional ways of benchmarking NRW are not useful in rationed systems.

This paper identifies key NRW issues for utilities operating under rationing and gives them help in identifying options for their NRW strategies.

The purpose is to study the possible environmental impact from a supercenter construction on a 313,643‐m² land by the Bayou Bartholomew.

The sources of information were field work, flood maps, flood models, 100 years of rainfall data, soil quality, water infiltration rate, and traffic flows in the areas around the supercenter. Rainfall data were used to find the frequency of flashfloods under different flood models. The supercenter center obstructs the virgin drainage of water down the bayou. Bernoulli's equation was used to estimate delays in the flashflood drainage following the constricted flow after the construction of the supercenter. Overloads of traffic flows on selected city roads in the event of submergence of the main road were studied.

A total of eight major flashfloods per century occur. Bernoulli's theorem predicts flooding over wider areas and of longer duration. About 32,248 m³ of recharging of groundwater will be affected. Traffic loads will increase by about three times on the state highway 15 beside the supercenter. Rain‐drained automobile engine oil drips will cause bayou's water quality to deteriorate.

Prediction needs to be checked during flashfloods occurrences. Water quality in the bayou upstream and downstream of the supercenter needs to be monitored.

Policy makers in the city government and urban development will benefit from the findings.

The paper upholds the multifarious environmental problems and as such it is of interest to urban planners, farmers, water quality monitors, groundwater hydrologists, and businessmen who would like to serve the community.

Seawater intrusion represents a major problem in many coastal aquifers all over the world. It degrades the water‐quality and hence the groundwater may become unsuitable for domestic and agriculture purposes. Due to the direct hydraulic contact between the freshwater and saline water in coastal aquifers and the density difference between the two water bodies, the seawater migrates inland. The problem is exacerbated when the groundwater abstraction rates exceed the natural recharge from rainfall events. The key to controlling this problem is to maintain the proper balance between water being pumped from the aquifer and the amount of water recharging it. The purpose of this paper is to present a coupled transient finite element model for simulation of fluid flow and solute transport in soils with application to study seawater intrusion in coastal aquifers.

The model includes coupling of fluid flow and solute transport. Transient density‐dependent flow and the dependency of dispersion on velocity are considered. After validation, the model is applied to predict the seawater intrusion in the Wadi Ham aquifer, UAE in vertical sections and the results are compared with those from a commercial code (SEWAT) which was used to simulate seawater intrusion in the aquifer in a horizontal section.

A good agreement is observed between the results of the current model in the vertical cross‐section and those of SEWAT in the horizontal cross‐section for the case of Wadi Ham. The results show that the model can predict the extent of seawater intrusion (and the transition zone) and distribution of salt concentration in the aquifer with a good accuracy.

The developed model includes coupling of fluid flow and solute transport in saturated and unsaturated porous media. Transient density‐dependent flow and the dependency of dispersion on velocity are considered. The model has been applied to a real world case study. A combination of the results in vertical and horizontal sections has been used to build a 3D picture of seawater intrusion in the aquifer.

The purpose of this paper is to construct a numerical model for the numerical analysis of the hydraulic transient profile in Trabalhador channel for filling and emptying maneuvers and to determine the water level in time. Model results support operational managers in the decision-making process.

Physical data were provided for the construction and calibration of the numerical model. The equations of Saint-Venant were approximated by a finite difference scheme and the numerical model was written in Fortran. The results of filling and emptying of the channel simulations were compared with the measured water levels.

Measured water levels and those simulated by the numerical model have shown good correlation. The time recorded for the filling and emptying of the canal was also close between the measured and simulated data. The simulation design flow pointed to inundation in the channel banks. Simulation water levels were slightly higher than those measured.

In this model, the combination of canals and pressure conduits was not considered.

The findings confirm the measured time for filling and emptying of the canal, as well as inundation of canal banks for the maximum design flow. These results help in the management process.

This paper presents a numerical model for hydraulic transient analysis in channels with good agreement with the field data.

Things seem to be going desperately wrong with the concept of the “brave new world” predicted by the starry‐eyed optimists after the Second World War finally came to an end. To those who listen only to what they want to hear, see everything, not as it is, but as they would like it to be, a new society could be initiated and the lusty infant would emerge as a paragon for all the world to follow. The new society in truth never really got off the ground the biggest mistake of all was to cushion millions of people against the results of their own folly; to shelter them from the blasts of the ensuing economic climate. The sheltered ones were not necessarily the ordinary mass of people; many in fact were the victims and suffered the consequences. And now that the state has reached a massive crescendo, many are suffering profoundly. The big nationalised industries and vast services, such as the national health service, education, where losses in the case of the first are met by Government millions, requests to trim the extravagant spending is akin to sacrilege in the latter, have removed such terms as thrift, careful spending, value for money from the vocabulary.
