Project Title:
Water Resources Management In Watershed Decision Support System – Phase I

Thematic Area:
GIS based Watershed Management

Location:
* Rampatnam watershed in Kolar, Karnataka
* Gandheshwari subbasin in Bankura, West Bengal

Objective:
* To perform requirement analysis to identify the users needs with respect to the water resources management aspects of the watershed management
* To conceive a GIS based water resource management segment (in the form of a simulation model) to be fitted in a Generic Watershed Management Decision Support System (WMDSS)
* To formulate the simulation model and implement on some of the experimental watersheds on pilot basis.
* To disseminate the software to the end-users and obtain feedback.

Abstract:
The Development objective of the project was to improve sustainability of development by adopting integrated area approach to rural development planning with a view to improving the lives of the target population through a spatial decision support system on a GIS platform and with a hydrological model (SWAT). The application was developed to help the end-user in integrated watershed management approach, concentrating on water resources management aspects.

Data Used:
* Spatial data: DEM, Landuse, Soil layers, Weather station Location, Village and district boundaries
* Non Spatial data: Daily rainfall, maximum minimum temperature, RH, Solar  Radiation, Soil and Crop related parameters, socio economic data

Highlights/Findings:
A GIS interface on GRAM++ has been developed using a very comprehensive water balance model namely SWAT model

Outputs:
* SWAT - GRAM Interface
* Soil Parameter Generator
* WMDSS Package – generalized watershed database management package to create, edit and query watershed related data was developed. The following figure depicts composite view of some segments of the application (Figure1).
* IMD Data Conversion Application – A facilitator to convert IMD raw data to processed data ready for use with Weather generator and other models
* A typical screen shot of the Application is shown here (Figure2).
