The freshwater management of rivers reservoirs in most countries evolved as an independent program that operate with distinct mandates, authorities, policies and implementation. Study elements include hydrographic surveys, hydrodynamic modeling of circulation and salinity patterns, sediment analyses, nutrient analyses, freshwater inflow optimization modeling, and verification of needs. For determining the needs, statistical regression models are developed among freshwater inflows and water sediments. Results from the models and analyses are placed into the Vaigai dam along with information on salinity viability limits, nutrient budgets and inflow bounds. The need to better integrate river reservoir management by combining Integrated water resources management (IWRM). This approach recognizes the river and branches of them and nearby lands or water resources are all elements of freshwater inflow management (FWIFM). Long-term monitoring is recommended in order to verify that implementation of future water management strategies maintain ecological health of the Vaigai dam and to provide an early warning of needs for adaptive management strategies.
