Project detail:
Administrative Approval and Expenditure Sanction (AA&ES) for Remote Sensing/Drone Technology related R&D project - “Geomorphic and Ecological Impacts of Sand Mining in Large Rivers as revealed from high resolution historical remote sensing data and drone surveys: Assessment, Analysis and Mitigation” under Namami Gange Program
3. Summary of the Project:
I. The major objectives of this project are as follows:
a. Assessment of geomorphic impacts of sand mining on rivers using historical scale satellite images supplemented with drone surveys with particular reference to erosional and aggradational hotspots.
b. Exploiting coherence change detection (CCD) techniques based on InSAR data for mapping erosional processes in river catchments.
c. Analysing geomorphic connectivity for identification of potential pathways of sediments from hillslope to channel using optical and InSAR data.
. Assessment of ecological impacts of sand mining using historical data sets.
. Assessment of associated hazards such as flash floods and bank erosion caused by indiscriminate sand mining superimposed by hydrological changes.
Integration of data for identification of hotspots of degradation in river catchments and suggestions for mitigation measures.
Formulation of region-specific policy guidelines for sand mining based on scientific understanding.
Work Package/outcomes & Window/Study Area:
project cost of INR 182.13 lakhs
