  • Utilizing analytic hierarchy process (AHP) for decision making in water loss management of intermittent water supply systems

    Increasing water demands, in parallel with water scarcity, force water utilities in developing countries to follow complex operation techniques for the distribution of the available amounts of water. The reduction of water losses from water supply systems can help fill the gap between supply and demand. This strategy is characterized by the variety of options, and identification of the most ...

  • Study of hydraulics and mixing in roof tanks used in intermittent water supply

    Roof tanks are common in low and middle income countries, due to the intermittent water supply. Their hydraulic and water mixing behaviour has not been studied. This paper presents the results of a study on mixing and water demand in roof tanks, based on physical and numerical models. Tracer tests were carried out on a real scale transparent wall laboratory model of a roof tank, and a ...

  • Assessment of water loss in Harare, Zimbabwe

    A major challenge facing water utilities is the high level of water losses, which affects the financial viability and adequacy of water in the system. A study was carried out from January to May 2012 to characterize water losses in selected areas of Harare, Zimbabwe. Assessment of the contribution of water leakage to total water loss was carried out through water audits in four selected ...

  • Inter-annual variations of Poyang Lake area during dry seasons: characteristics and implications

    Variations in a lake area constitute an important indicator of the modifications of the lake hydrology. This paper explores the inter-annual variations of the Poyang Lake area during the dry seasons occurring within the 1961 to 2010 period and further quantifies the severity of dryness recently endured during the 2000s. A physically based hydrodynamic model of Poyang Lake established the ...

  • Evaluating the influence of water table depth on transpiration of two vegetation communities in a lake floodplain wetland

    Groundwater plays an important role in supplying water to vegetation in floodplain wetlands. Exploring the effect of water table depth (WTD) on vegetation transpiration is essential to increasing understanding of interactions among vegetation, soil water, and groundwater. In this study, a HYDRUS-1D model was used to simulate the water uptake of two typical vegetation communities, Artemisia ...

  • Source identification of sudden contamination based on the parameter uncertainty analysis

    It is important to identify the source information after a sudden water contamination incident occurs in a water supply system. The accuracy of the simulation model's parameters determines the accuracy of the source information. However, it is difficult to obtain the true value of these parameters by existing methods, so reduction of the errors caused by the uncertainty of these parameters is ...

  • Cyto- and genotoxic profile of groundwater used as drinking water supply before and after disinfection

    The assessment of the toxicological properties of raw groundwater may be useful to predict the type and quality of tap water. Contaminants in groundwater are known to be able to affect the disinfection process, resulting in the formation of substances that are cytotoxic and/or genotoxic. Though the European directive (98/83/EC, which establishes maximum levels for contaminants in raw water ...
