  • The role of flood plains in the sustainable water supply of Pécs
  • Danube ; Floodplain ; Hungary ; Lower valley ; Town ; Water ; Water management ; Water supply
  • The main aim of the paper is to present the unsustainable conditions of water supply of Pécs and to detect the main reasons behind it. First the special role of the flood plain along the Lower Danube Valley in the water supply of the town
  • is considered, then obstacles to achieving sustainable water management are analysed. - (JS)
  • Modelling soil water supply to crops
  • The supply of water by the soil to meet the transpirational demand of crops, has been modelled on the assumption that water supply is directly related to soil water potential. Results of field testing and discussion.

  • Allapotfelvétel a vizellatas helyzetérol a Dunantuli-kozéphegységben Recording the state of water supply in the Transdanubian Mountains
  • It talks about the development of communal water-supply. It is a problem at present to find enough water. How can we protect water from pollution ? These are the main questions in this study. - (DLO)
  • Water Supply and Health in India
  • Health ; India ; Pollution ; Regional disparities ; Water ; Water quality
  • In many parts of India, neither the quantity nor the quality of drinking water supplied to the public comply with required standards. In addition there are vast disparities between different regions and communities. The article deals with a chronic
  • Nature park ; Poland ; Water ; Water supply
  • The article concentrates on presenting changes in the water and sewage systems density in the Krajna Landscape Park (KLP). The article also presents the scope of the water supply and sewage systems between 1995 and 2006. The analysis has been
  • carried out on the basis of the following variables: length of the water supply and sewage systems, systems’ density indicator, and the length of the water supply system per 1 km of the sewage system. - (BJ)

  • Water supply problems of Riyadh, Saudi Arabia in Water in the urban environment.
  • Regulating water services for the poor : the case of Amman
  • Jordan ; Poverty ; Regulation ; Service ; Town ; Urban administration ; Urban infrastructure ; Vulnerability ; Water supply
  • A private management contractor was introduced to Amman, along with a form of economic regulation. The paper investigates the status of water supply service and regulatory arrangements with respect to poor and vulnerable consumers. It identifies
  • specific regulatory challenges. In its extremes of connection coverage, water scarcity and population, the management of water supply presages the pro-poor water service challenge of many economies irrespective of the extent to which they may achieve

  • Fog ; Northern Cape ; Resource management ; Rural development ; South Africa ; Sustainable development ; Water ; Water needs ; Water resources ; Water supply
  • An investigation of domestic water inadequacy in 1995 identified Lepelfontein as a settlement with an insufficient supply of fresh water, initiating a pilot study on fog harvesting aimed at improving fresh water supply and water security
  • Fog : a possible solution to rural water problems ?
  • Countryside ; Fog ; Fresh water ; Project ; South Africa ; Water ; Water needs ; Water resources
  • as a domestic water supply, notably the South African Fog Water Project. - (AJC)
  • Acute water shortages are experienced regularly in many areas. It is thus of the greatest importance to identify other sources of water in these regions. Fog is one such new source of fresh water and shows a significant potential for use
  • Water management in the Egyptian Delta : problems of wastage and inefficiency
  • Crop ; Delta ; Egypt ; Irrigation ; Nile ; Rural geography ; Seasonal variability ; Water ; Water management ; Water needs
  • Through a case study of one region the paper seeks to outline the causes and extent of wastage/inefficiencies in the distribution of irrigation water in rural Egypt. By studying water use as a simple supply/demand relationship, it was possible
  • to locate where wastage and inefficiency were occurring. This was seen to be primarily on the supply side, although the inflexibility of farmer demand was also seen to be a significant factor in the mismatch of supply and demand patterns.
  • Drinking water ; Karst ; Planning ; Slovenia ; Spring ; Water ; Water economics ; Water needs ; Water quality ; Water supply
  • Karst springs are important resources of local drinking water supply, covering almost half of the country’s needs. This paper discusses water supply in the past and today, problems and challenges that it is facing. The quality of karst water sources
  • is good but the protection of catchment areas is insufficient. To keep our biggest reservoir of qualitative drinking water safe, further planning of water supply will need to base on appropriate research, as are the presented ones. - (L'A.).
  • Possibilities for water conservation in Bulgaria
  • Bulgaria ; Consumption ; Demand ; Water ; Water economics ; Water management ; Water use
  • Existing water resources can become inadequate if water losses are too important and if there is an irrational use of water. Water conservation could solve some water supply problems by providing more reasonable water consumption and additional time
  • for development of new resources. The possibilities for reducing water use and the need for developing a national conservation program are discussed. An analysis of the variables which affect water use is performed. Developing of water-use efficiency standards
  • for plumbing fixtures and conservation-oriented water rates and measures are proposed.
  • The Flushing Time Based on Underground Supply in the Upper-Most Located Łeczna-Włodawa Lakes
  • Geological structure ; Hydrological regime ; Lake ; Poland ; Precipitation ; Underground water ; Water body ; Water shortage ; Water supply ; Watershed ; genetic types of supply ; lakes ; underground inflow ; water mixing
  • , the lakes in question constitute a distinctive group among the Łeczna-Włodawa Lakes. They are located in the borderland of the Cretaceous Chełm Hills (part of the Polish Uplands) and Polish Lowland. The quantity of the underground water supply was one
  • , as super-passive due to their water flushing time (>10 years). However, the average flushing time of the water in lakes Tarnowskie, Chuteckie, Pniówno and Syczyńskie, based on the underground supply, amounted to 606, 211, 54 and 79 days, respectively
  • Flushing time (Tf) is an important factor which determines the hydrological, ecological and chemical functioning of lakes. However, it has never been calculated on the basis of underground supply for Polish Lakes. Due to their high altitudes
  • of the key factors which make these lakes so distinctive. During periods of low precipitation, water shortages occurred in the lakes, especially Pniówno and Syczyńskie. The Łeczna-Włodawa Lakes are commonly distinguished, among other Polish water bodies
  • . The territorial conditions (e.g. geologic structure of catchment areas or thickness of unsaturated and saturated zones) were the most important factors that determined seasonal fluctuations of the supply to the lakes.
