Effective water resources planning, water allocation and management depends on our ability to illustrate and build water resources balance with respect to various water sources (surface water, groundwater, recycled water) and multi-sectoral uses (domestic, agricultural, industrial, energy) in a given spatial and temporal context of a river basin. The various sources, uses, and operational functions make up a water system with which basin administrators and decision makers can evaluate, tailor-made, and plan for multipurpose uses of water by taking into account changes to demand and supply due to factors related to climate changes, demographic, economic development, living standards and styles.
However, with multiple sources (surface water, groundwater, recycled water) and competing uses of water (domestic, agriculture, industry, energy) under multiple factors (population growth, change in life style, climate change, economic activities), the planning process becomes complicated decsion matrix.
WaterSys is a decision framework for multi-sectoral water allocation and management to plan inclusively, develop water resources economically, allocate water optimally among competing users, and manage water resources sustainably by taking into account the dynamics of population growth, climate change and economic activities. It provides a quantitative assessment and analysis of water resources demand and supply in a dynamic (time varied) situation at local, national, and transboundary levels.
