Decision Support System (Planning) - DSS
  Development of Decision Support System (DSS) is one of the components of vertical extension which encompasses all those activities, which would utilize and enhance the use of HIS data that had been observed (various spatial and historical time series data) and computerized under H.P.I activity.
The Decision Support System (Planning)-DSS, pertains to water resources planning, G.W. planning, Reservoir operation, irrigation management, drought management and conjunctive use of surface and Ground water. The elements of DSS (Planning) such that they are intended to support decisions required at relatively infrequent time intervals such as one week, 10 days, one month, or longer planning horizon.
A DSS provides the Water Management Authorities a well structured, user friendly, practical and complete water resources management information system. DSS may assist decision makers in taking the right decisions on the basis of good comparison of different strategies under various scenarios.
Decision Support System allows decision makers to analyze hydrologic data, run hydrologic simulation models, run basin water allocation models and study the effect of potential decisions. A DSS is designed to access or display hydrologic data in an easily accessible manner, to model dynamic hydrologic conditions, and to determine the ability of the river system to meet future demand based on operational and administrative use of storage. Often these DSS allow users to simulate and evaluate various “What if” scenarios for river operation alternatives.
Water Resources Planning DSS includes various modules, which include extensive data in five major categories :
 
  • River network configuration
  • River Hydrology
  • Existing & planned hydro facilities
  • Water use
  • Reservoir/Lake regulation rules
  The actual river system is represented by a network of river nodes, reaches and reservoirs each with its own attributes. River nodes represent locations of local inflows, water withdrawals and returns. River reaches represent physical river segments and their water transport characteristics.
Reservoir represents man made or natural lakes that may support various water uses including water supply, flood control, drought management, hydro power etc.
Conceptually Water Resources Planning DSS give emphasis on Water Management issues, which are becoming increasingly complicated in relation to society’s requirements and needs. It has been recognized that an integrated and multidisciplinary approach must be adopted. A DSS can provide a systematic procedure for analysis and evaluation of alternative course of action.
In the State of Maharashtra’s Upper Bhima Basin(Basin up to Ujjani reservoir) has been selected as a Pilot Basin for DSS (Planning) under Hydrology Project Phase-II, with the scope of DSS as Planning of Surface and Ground water, Drought Management & Management of floods as well.
Planning DSS will be developed by consultant appointed by National Institute of Hydrology, Roorkee. NIH has appointed DHI (Denmark) as consultants for development of DSS (P) in December 2008 for the period of 4 years. Maharashtra has been chosen as the Pilot state for Development of DSS among 9 participating states in the country.
 
  The Present status of work is as under:
 
  • Appointment of Consultant in November 2008 by NIH, Roorkee.
  • Needs Assessment Report completed.
  • DSS Model Conceptualization Report completed
  • Procurement of ARC GIS Software is completed.
  • Required data is supplied to DHI Consultant .
  • Required GIS layer & remote sensing data is procured.
  • Procurement of computer hardware & software except backup media is completed.
  • Flood control rules applied, actual water use for Khadakwasla complex applied, Model has been run.
  • Report of Upper Bhima setup & calibration of model is done (NAM & Mike basin).
  • Generic Model for DSS(P) is ready for customization.
  Trainings:
   
  DHI consultant has conducted the following training courses
 
  • Exposure to Mike Basin, GIS and Arc GIS, NAM-Rainfall-Runoff Model and Temporal Analyst at NIH, Roorkee.
  • Hands-on training regarding the above topics and software at NWA, Pune.
  • “Training course under Decision Support System (Planning) for IWR Planning & Management” during 2nd August to 10th September 2010 @ Denida Fellowship Denmark.
   
  Expected Output from DSS(P):
 
  • Specific Output
    • Drought Managemen
    • Flood Control of Pune & Pandharpur city
    • IWRM for the Sub Basin
    • Integrated Reservoir Operation Model
    • Economic returns
  • General Output
    • Conjunctive use of SW & GW
    • Application of use of Advanced Irrigation Systems
    • Water conservation methods
    • Protection of Wild Life, Forest , Flora & Fauna of the Basin
