Mapping chlorophyll-a in upper lake Bhopal using IRS-1C data

This paper on the GIS Development site describes the findings of a study that aimed at mapping chlorophyll-a in upper lake, Bhopal using Irs-1C data. Field sampling in the lake was conducted on Nov 7, 1997. The date was fixed keeping in mind the pass of the satellite over the study area during field sampling so that accurate relationship of chlorophyll -a with sensor records may be established. IRS-IC passes over the same area after 24 days.Read More

Spatial modelling approach to water pollution monitoring in the sugar belt of Maharashtra along the Krishna river

This paper on the GIS Development site highlights the findings of a study taken up for the monitoring, identification and suggesting preliminary measures of water pollution control in the Satara-Sangli stretch (stretch-I) of the Krishna basin in Maharashtra with the help of Geographic Information System (GIS). The stretch-I, also known as the country's sugar-belt, has been identified by CPCB and MPCB (Maharashtra Pollution Control Board) for the restoration of water quality under the National River Action Plan (NRAP).

Remote sensing based rapid watershed health appraisal – A case study of NWDPRA watersheds of Rajasthan

This article on remote sensing based rapid watershed health appraisal presents a case study of NWDPRA watersheds of Rajasthan. Eight watersheds distributed across different agro climatic zones of Rajasthan were studied for rapid appraisal of their health condition after 8 years of treatment. Major remote sensing based indicators studied include landuse, overall biomass, vegetation along drainage buffer zone and number and extent of water body.

AVSWAT- A spatial decision support system for land and water management and its application for watershed management in Bankura district of West Bengal

The article deals with AVSWAT- A spatial decision support system for land and water management and its application for watershed management in Bankura district of West Bengal. Decision Support Systems (DSS) are defined as computer-based information systems designed to support decision makers interactively in thinking and making decisions about relatively unstructured problems. Spatial Decision Support Systems (SDSS), which are the integration of DSS and GIS was initiated by Densham and Goodchild ( 1988) are emerging as efficient tools for managing natural resources like land and water.Read More

Erosion response model for watershed prioritisation in Bajaj sagar sub catchment

This case study presents a erosion response model for watershed prioritisation in Bajaj sagar sub catchment of Mahi basin. The natural hydrologic processes like erosion of soil, movement of soil and its deposition in various parts of reservoir are very crucial phenomena occurring in any watershed. Erosion of soil is a very complex process which is affected by many factors and the loss caused is irreversible.Read More

Micro-watershed development plans using Remote Sensing and GIS for a part of Shetrunji river basin in Bhavnagar district of Gujarat

In this study an approach using remote sensing and GIS has been applied to identify the natural resources problems and to generate locale specific micro-watershed development plans for a part of Shetrunji river basin in Bhavnagar district, Gujarat. Micro-watershed level planning requires a host of inter-related information to be generated and studied in relation to each other. Remotely sensed data provides valuable and up-to-date spatial information on natural resources and physical terrain parameters. Geographical Information System (GIS) with its capability of integration and analysis of spatial, aspatial, multi-layered information obtained in a wide variety of formats both from remote sensing and other conventional sources has proved to be an effective tool in planning for micro-watershed development.Read More

Remote sensing based rapid watershed health appraisal: Performance of the National Watershed Development Project for Rainfed Areas

This study presents a remote sensing based rapid watershed health appraisal of NWDPRA watersheds of Rajasthan.  Eight micro-watersheds, distributed over different agro climatic zones of Rajasthan, India, were studied for their performance in terms of biomass gain, landuse change and changes along drainage line, if any. The study area is distributed across 8 agro-climatic zones ranging from desertic western plain to humid southern and south-eastern plain. The satellite data prior to treatment year (1988) was compared with post-treated year (1996), to reveal the noticeable changes over a span of 8 years.Read More
