DecisionA reasoned choice among alternatives

Definition of a DSS Computer based systems integrating tools and databases that assist a decision-maker in making informed decisions and analyze consequences.

Misconception: A DSS takes decisionsUsing a DSS, a project manager is able to make rational use of resources without an in-depth knowledge of modeling techniquesProvides timely informationCommunicate result to a larger audienceOpen and unbiased workingScenario analysis

Surface water planningIntegrated operation of reservoirsConjunctive surface and ground water planningDrought monitoring, assessment and managementManagement 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 networkA hydrological model (NAM) is calibrated for each sub-basin to estimate the hydrological components (evaporation, rainfall recharge, overland flow, interflow and base flow) ~ SoulAn 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

ObjectiveNAM model provides a conceptual representation of land phase of hydrological cycle and simulates rainfall-runoff processes at the catchment scale.Basic data requirementsPrecipitation time seriesTemperature time series (for snow melt modeling)Evapo-transpiration time seriesObserved discharge time seriesBasic model outputsCatchment runoff Subsurface contributions (base flow, interflow)Actual evapo-transpirationGroundwater recharge and levelsSoil moisture storage content

Process and analyse GIS and time series informationPublish selected information (general, drought, flood..)Model applications for long-term/short-term planning

Specific runoff in the basinRain fall distribution

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?

Combined use of SW & GW in Sri Ram Sagar ProjectScenario I: no restriction on SW useScenario II: limited SW abstraction by head and middle section users permitted

To study viability of inter sub-basin water transfer during monsoon to rain shadow regions to augment ground resource.
