Site Suitability Using GIS
MAPPING OF SUITABLE SITE FOR THE MINI HYDRO POWER PLANT USING SWAT MODEL AND GIS TECHNIQUE
ABSTRACT
Hydropower is one possible method of generating electric power close to potential consumers. The accessibility of the possible sites which are mostly located in mountainous regions, for which large amount of data is required, which consumes huge amount of money and time. Since small hydropower schemes, used to produce electrical energy which is benefited for nearby small towns, villages or small industries. Expensive ground investigations must be carefully targeted to the areas which are most likely to yield useful sites for hydropower development.
In order to cope with these problems, the present study proposes the use of Geospatial Technology & Soil Water Analysis Tool (SWAT) hydrological Model to select the feasible sites of small hydropower projects.
Using ArcGIS various thematic maps were generated such as Digital elevation model (DEM), Stream order network, Land Use and Soil maps etc. for the hydrological analysis. Discharge is simulated from the SWAT hydrological model. SWAT model is a conceptual, distributed, continuous-time hydrological model that can simulate the water, sediment, nutrients and pesticides cycle. To induce a level of confidence in the generated results, the catchment was modeled using Indian Meteorological Department (IMD) gridded precipitation and temperature datasets. The model was calibrated and validated with observed stream flows.
The reconnaissance study using GIS techniques identifies suitable site in Malapraba catchment likely to yield useful sites for small scale hydropower development. The hydrological factors yield a map representing an overall feasible potential site for small hydropower development. In the present study sub catchment 1 in Bennihalla, tributary of Malapraba river is more suitable for small scale hydropower plant with a power potential of 7.95 Mw.
