Compounding this scarcity is the deterioration of water quality in several developing countries, mainly in river basins with rapid change of land usage. Local solutions for these problems are hampered by a lack of commitment to solving problems related to water and poverty, inadequate and inadequately targeted investment, insufficient human capacity, ineffective institutions, and poor governance (Molden et al., 2007). To provide sustainable water resource development and secure water availability for competing user groups, future water management may observe the water accounting approach (Cai et al., 2002), which recognizes the various water users of a basin and the water flows in terms of net water production or net water consumption. aSurface resistance algorithm aWater deficit1 aHERNANDEZ, F.
