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

  4. DSS (P) Components • 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

  5. Modeling Methodology under DSS (P) • 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

  6. NAM Model under DSS (P) • 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

  7. NAM Results Observed/Simulated Surface Water Flows

  8. NAM Results Tabular Presentation of Components of Hydrologic Cycle

  9. NAM Results Observed/Simulated Groundwater Levels

  10. River Basin Model Concept

  11. River Basin Schematization

  12. Sample Basin Schematization in a Model

  13. Integrated SW/GW Modeling

  14. DSS (P) Main Functionalities • Process and analyse GIS and time series information • Publish selected information (general, drought, flood..) • Model applications for long-term/short-term planning

  15. DSS (P) – Generation & Comparison of Scenarios Properties Model explorer Model structure Tools

  16. DSS (P) - Main Windows Layout

  17. DSS (P) – Association between GIS & Time Series

  18. DSS (P) – Use of Spreadsheets

  19. DSS (P) – Publishing information on web

  20. DSS (P) – Brief Description of Some Applications Water Availability in the Basin Specific runoff in the basin Rain fall distribution

  21. DSS (P) – Brief Description of Some Applications Monthly Variation of Water Yield

  22. Seasonal Planning Cropping pattern Scenario 1: Reduce the area of paddy during Rabi (More Pulse and Maize) Scenario 2: Short duration Paddy and Pulses(conjunctive use) • 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.

  23. DSS (P) – Brief Description of Some Applications Seasonal Planning of Reservoirs • 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?

  24. DSS (P) – Brief Description of Some Applications Conjunctive Use of SW & GW • Combined use of SW & GW in Sri Ram Sagar Project • Scenario I: no restriction on SW use • Scenario II: limited SW abstraction by head and • middle section users permitted GWT in m

  25. DSS (P) – Brief Description of Some Applications Drought management • Drought Indicators • Assessing the impact of check dams and artificial recharge measures

  26. DSS (P) – Applications Chattisgarh State (Study Basin – Sheonath basin) • Operation analysis of Tandula reservoir • Conjunctive use in command areas • Benefits of changes in cropping pattern and canal lining • Inter basin Transfer (from RSP to Tandula Tank) • Groundwater seasonal planning and artificial recharge

  27. DSS (P) – Applications Odisha State (Study Basin – Hirakud & Upper Tel Basins • Conjunctive use of SW & GW in Hirakud command • Mitigation of water logging through increased GW pumping in Hirakud command • Benefits of changing cropping pattern in Hirakud command • Benefits of changing cropping pattern in Upper Tel basin • Drought management measures in Upper Tel basin

  28. DSS (P) – Applications Karnataka State (Study Basin – Palar & Tungabhadra Basins Tungabhadra Dam Palar River Basin

  29. DSS (P) – Applications Gujarat State (Study Basin – Mahi River Basin

  30. DSS (P) – Applications Maharashtra State (Study Basin – Upper Bhima Basin

  31. DSS (P) – Applications Pavana Seasonal Planning Initial Level FRL Initial Level Reduced Reduced Demands

  32. State SW-GW Installations in Servers
