Based on comprehensive analysis in a national research program, this book covers water structure and quality, surface water, groundwater, water treatment, irrigation technology and industrial water pollution, one of the main environmental problems of our time

This is a conference paper. ; The participatory Action Research on The Role of Communities in the Management of Improved rural Water Supplies involves the understanding of the dynamics, and the challenges inherent in the decision making process within the social environment in which the improved water supplies are located. The Participatory Action Research is enhancing the understanding of the dynamics challenges and constraints of community management. The overall project guidance and coordination is provided by International Centre for Water and Sanitation (IRC), The Hague with funding from The Netherlands Government. The collaborating institutions are NGO's in six developing countries Colombia, Guatemala (Latin America); Nepal, Pakistan (Asia); and Cameroon, Kenya (Africa). Network for Water and Sanitation International (NETWAS) is a Regional NGO collaborating in this PAR Project. The overall project components include preparation, community selection, community diagnosis, problem identification, identification of promising solutions, experimentation and monitory and evaluation.

Hydrological drainage/river basins constitute highly heterogeneous systems of coupled natural and anthropogenic water and pollutant flows across political, national and international boundaries. These flows need to be appropriately understood, quantified and communicated to stakeholders, in order to appropriately guide environmental water system management. In this thesis, various uncertainties about water and pollutant flows in drainage/river basins and their implications for effective and efficient water pollution abatement are investigated, in particular for mine-related heavy metal loadings in the Swedish Dalälven River basin and for nitrogen loadings in the Swedish Norrström drainage basin. Economic cost-minimization modeling is used to investigate the implications of pollutant load uncertainties for the cost-efficiency of catchment-scale abatement of water pollution. Results indicate that effective and efficient pollution abatement requires explicit consideration of uncertainties about pollution sources, diffuse contributions of the subsurface water system to downstream pollutant observations in surface waters, and downstream effects of different possible measures to reduce water pollution. In many cases, downstream load abatement measures must be used, in addition to source abatement, in order to reduce not only expected, but also uncertainties around expected pollutant loads. Effective and efficient environmental management of water systems must generally also consider the entire catchments of these systems, rather than focusing only on discrete pollutant sources. The thesis presents some relatively simple, catchment-scale pollutant flow analysis tools that may be used to decrease uncertainties about unmonitored water and pollutant flows and subsurface pollutant accumulation-depletion and diffuse loading to downstream waters.

ABSTRACTThe problems of water‐colour management in peatland catchments are discussed. Colour may be managed in three areas of the reservoir catchment system: on the catchment itself, in the channel/conduit system and within the reservoir. Whilst a number of workers have considered the management of catchment areas and some have evolved tributary turnout strategies, no previous research has considered the role of the reservoir in the amelioration or enhancement of water colour. The management of water colour at Thornton Moor catchment (near Bradford) is described. In this catchment a staged approach has been adopted, with colour being managed in an integrated manner at three stages along the catchment/conduit/reservoir system.
