Misconception: A DSS takes decisions ---(No) o Using a DSS, a project manager is able to make rational use of resources without an in-depth knowledge of modeling techniques o Provides timely information o Communicate result to larger audience o Open and unbiased working o Scenario analysis

 Surface water planning  Integrated operation of reservoirs  Conjunctive surface and ground water planning  Drought monitoring, assessment and management  Management of surface and ground water quality

A river basin is divided into a number of sub- basins based on the location of hydraulic structures and hydrological network A hydrological model ( NAM ) is calibrated for each sub-basin to estimate the hydrological components (evaporation, rainfall recharge, overland flow, interflow and base flow) ~ Soul An allocation model ( MIKE Basin ) in conjunction with hydrological inputs is used to allocate the available SW and GW ~ Heart DSS is used to analyze scenarios ~ Brain

Objective NAM model provides a conceptual representation of land phase of hydrological cycle and simulates rainfall-runoff processes at the catchment scale. Basic data requirements Precipitation time series Temperature time series (for snow melt modeling) Evapo-transpiration time series Observed discharge time series Basic model outputs Catchment runoff Subsurface contributions (base flow, interflow) Actual evapo-transpiration Groundwater recharge and levels Soil moisture storage content

Seasonal Planning The likelihood of filling the Hirakud reservoir during the current or next monsoon and the risk of having insufficient water for the users at the end of a dry season. Cropping pattern Scenario 1: Reduce the area of paddy during Rabi (More Pulse and Maize) Scenario 2: Short duration Paddy and Pulses (conjunctive use)

For given scenarios of planned water allocation:  What is the risk of reaching critically low levels in coming dry season?  What is the likelihood of filling the reservoir in the coming wet season?
