This study aims to test the role of the state of occupation, represented in Israel, as one of the most significant challenges, which faces the Jordanian water security. Where Israel expands in its policy and ideology everyday its hydro-hegemony over the Jordanian waters. Hence, its acts result in negative consequences on the Jordanian water and food security, which in turn affects the Jordanian national security as a whole.

This study relied on the following two approached to tackle its problem: first: descriptive approach: the descriptive approach depends on defining the apparent features and describing their nature and the type of the relationship between its variables. It aims to achieving a better and deeper understanding on the situation of its future policies and measures. And research uses the system analysis approach to handle the subject matter. Given the influence of water on the development, Jordan, as an organic or a political and social state, takes into account the reasons and causes of development. Jordan turns into an active political state, with water as an influencing factor on it. This premise represents the core of the system analysis approach.

The research concluded that the Israeli theft of the Jordanian waters is the main factor in the Jordanian water crisis. If Jordan had received its usurped water rights by Israel, it could have been able to solve its water issue represented in the increasing deficit in its water balance. Therefore, the Israeli hydro-hegemony on the Jordanian water resources caused the imbalance in its water security and, in turn, caused the development process to falter in general.

The value of the research lies in the fact that it addresses the most important reasons behind the water crisis in Jordan, represented in the Israeli control over the Jordanian water resources and the research shows that the amount of water stolen by Israel is enough to solve the water crisis in Jordan.

There is no clear answer to the question as to what kind of humic substances (HSs) (fulvic acids (FAs) or humic acids (HAs)) is primarily responsible for colour of water in water bodies. To resolve this problem, the purpose of this paper is to compare optical properties of the samples of river water with solutions (considered as standard) containing HAs and FAs in different concentrations.

The author sampled two typical unpolluted rivers of Karelian Isthmus (Leningrad Region, North-Western Russia) with different water colours – Vyun with light-brown water and Kivioja with dark-brown water.

It is revealed that the shape of the light absorption curve for both rivers is similar to that of FAs. Among the coefficients, a 364 * is unsuitable for differentiation between HAs and FAs due to its wide transgression. In contrast, the E₅₄₀ coefficient allows one to separate these groups of HSs very well. The E₅₄₀ values of the river water samples categorise them as FAs. The values of a 440 * indicate that river waters, especially from Kivioja, contain FAs with a large molecular weight in comparison with soil FAs (up to 1.75-fold higher). It shows a distinct character of river water HSs, which is consistent with the published data.

The results outline a more direct approach to decision support in the sphere of ecological monitoring of river water.

The author has concluded that river waters are coloured by FAs.

The tannery industry impacts strongly on water bodies due to the presence of chemical substances, such as chlorides, sulphates, chromium and other pollutants. This study has been carried out with a view to enhance the environmental compatibility of the Arzignano tannery district (northern Italy) which is the largest in Italy, by improving the quality of the Fratta-Gorzone River. Sediment quality, according to the driving forces-pressure-state-impact-response (DPSIR) scheme, has been developed as a significant impact indicator to be applied at basin level. The purpose of this paper is to discuss the above issues.

Data were produced during institutional monitoring and control activities carried out by ARPAV (Veneto Region Environmental Prevention and Protection Agency) according to official methods. To define the environmental impacts on the river basin, a statistical assessment was performed on water and sediment quality data to establish the degree of correlation for the main pollutants along the river stem.

In the basin considered, sediment quality presents high levels of contamination from heavy metals – in particular chromium (Cr) (III) – as well as organic pollutants. Investigation of the pressure sources revealed that the discharge from the Arzignano tannery district is the main source of Cr (III), according to background studies performed in the same area.

The quality of river sediments must be improved in order to avoid the re-suspension/solubility of pollutants; dredged materials with high polluting substances must be managed with specific precautions in order to safeguard the environment.

The river studied is currently the only significant water body in which sediment monitoring has been performed in the Veneto Region (Italy) since 2002. This study presents issues linked to the characterization of river sediment and the correlation between sediment quality and water pollution and prior and current pressure sources.

Water protection is one of the primary objectives of the Water Framework Directive 2000/60/EC. The paper aims to identify suitable indices for water quality and specifically for water used for irrigation in the Fratta‐Gorzone river basin (Northern Italy) affected by discharges from the largest tannery district in Italy.

The DPSIR framework is proposed here for the development of a water quality monitoring and control system. A set of indices is applied as a comprehensive environmental management system in order to: assess the degree of achievement of water quality objectives; identify measures to be applied to pressure sources; verify the extent of application of local measures.

The highest values measured in the river Fratta‐Gorzone refer to the following parameters: chemical oxygen demand (COD), chlorides, sulphates, chromium, E. coli and, in some cases, other parameters. At basin level, the objectives set by the WFD and by local regulations must be achieved by applying appropriate discharge limit values. Water quality for irrigation use and the impact of the tannery district is critically presented and discussed according to available data, and refers to the monitoring project which was developed as a result.

The inflow from an irrigation channel, which conducts freshwater from the Adige river to the Fratta‐Gorzone river and empties just beyond the discharge point for effluent from the tannery district, favoured a general improvement in river water quality, as a result of dilution, particularly for irrigation purposes.

An environmental management system is outlined, with a proposal for a specific set of indices to be used as part of the monitoring and control activities for the integrated management of river basins, especially those affected by industrial tannery discharges.

The purpose of this study at the level of sustainability of oxbow lake was intended to determine the status of sustainability, leverage attributes and driving factors in the management of oxbow lake in Buluh Cina village in Kampar, Riau, Indonesia.

The types of data collected include primary data and secondary data. Data was collected using survey methods, library research, laboratory analysis and interviews. The analytical method used this study is multidimensional scaling (MDS) analysis and prospect analysis. Sustainability analysis is done using the MDS analysis approach with the help of RapOxbow software and compared to Monte Carlo analysis results.

The current sustainability status of the management of Lake Baru ecosystem according to a number of dimensions is considered sustainable with a sustainability index value of 50.95. Meanwhile, the analysis results of each dimension shows that the sustainability index for the ecological dimension is 42.56 and the sustainability index for the economic dimension is 47.44, which means that the index is less sustainable.

The approach of this research is MDS analysis and prospect analysis and research locations in Buluh Cina village in Kampar, Indonesia which have never been studied before. This is one of few studies that investigates comprehensively the analysis of management sustainability, especially in the dimensions of ecology, economics and socio-culture, especially in Indonesia.

The purpose of this paper is to assess the ground water quality and salinity issues in the fast developing coastal urban lands of two river basins of Thiruvananthapuram district, Kerala, South India.

In order to address the water quality of the basins, field sampling was conducted and the samples were analysed in the laboratory. A comparison with water quality standards was also made and the interpretations of the results were done using GIS and statistical tools.

The values of conductivity, chlorides and salinity show that the coastal areas of Neyyar and Karamana basins are severely affected by salinity intrusion in addition to the pollution problems. More than 90 per cent of the samples are with hardness lower than 100 mg/l. About 70 per cent of the study area is with calcium concentrations lower than 25 mg/l. The content of sulphate and magnesium in Poovar and Poonthura coastal stretches is found to be higher compared to other regions.

Since not much work has been published from the study area on these aspects, the hydrochemical characterization is a very important in deciphering the quality of ground water for its proper management. The water quality evaluation and salinity intrusion studies are very important for the future planning and development of this area.

Total organic carbon (TOC), dissolved organic carbon (DOC) and other physicochemical parameters of the Birim River, which serves for drinking and domestic purposes for rural mining communities, were analysed to assess the suitability of water quality for human consumption.

In total, 40 samples were collected from 20 sampling sites during the rainy season from July to September and the dry season from December to February in addition to two repeat samples and two blank samples. Samples were analysed for physiochemical parameters and the results were compared with World Health Organisation standards (WHO).

Data obtained for both rainy and dry seasons indicated TOC ranged from 1.1 to 7.3 mg/L and DOC 1–7.2 mg/L; pH, 5.6–8.63; temperature, 23.3–29.3°C; turbidity, <1.00–869NTU; apparent colour, <2.5–600 mg/L Pt-Co; true colour <2.5–150 mg/L Pt-Co; alkalinity, 27.8–80.4 mg/L; total suspended solids, <1.00–998 mg/L; electrical conductivity, 82–184 µS/cm; and bicarbonate, 33.9–98.1 mg/L. Particulate organic carbon (POC) was constituted between 1 and 10% of the TOC. Values for pH, turbidity, total suspended solids, and true colour indicated contamination of the river. p -value of <0.05 between seasons for the physicochemical parameters also suggests that the water is polluted.

Water from the Birim River is unsuitable for human consumption and may constitute a serious health risk to the consumers.

The paper yields immense value to inhabitant of communities using surface water affected by mining activities, policy makers in sustainability. It warns of the unsuitability of water from the Birim River for human consumption due to the potential health risk to consumers.
