data requirements for ganga river basin management plan
DESCRIPTION
This presentation by Prof. A.K. Gosain describes the data requirements for the Ganga River Basin Management Plan. What are the types of data sets that need to be explored and how would they be used in the studies related to GRBMP.TRANSCRIPT
Data Requirements
• Basin Characteristics• Hydro-meteorological Data• Projects Data• Data on Pollution• Demographic Data
Basin Characteristics
• Basin delineation• Drainage system – SRTM• Landuse/Landcover• Soil properties of the catchments – Global and
National data sources • River cross-section data
Digital Elevation Model
Hydro-meteorological Data• Meteorological data - IMD• Flow data at gauging sites - CWC and State
Water Resources Departments• Sediment data; volume and characterization –
CWC/State Govt. agencies• Ground water fluctuation data – CGWB/State
GW Boards• Flow cross sections and rating curves at
various stream gauging sites - CWC and State Water Resources Departments
Percentage share of major water balance in Ganga Basin components w.r.t. precipitation
Actual ET43%
Surface Runoff28%
Lateral Flow3%
Shallow Groundwater recharge
24%
Deep Aq Recharge1%
Scenario 1: Baseline - Virgin Condition
Projects Data• Data on water utilizations for– Agricultural– Domestic– Industrial and other uses
• Data on water resources projects including reservoirs and diversion facilities– Existing– Under implementation– Proposed
Storage Projects in Ganga Basin
Data on Pollution
• Point sources– Domestic sewage– Industrial
• Non-point sources– Data on use of fertilizers– Pesticides
• Data on water quality observations– Surface – Ground water – CPCB, CWC, CGWB, State Pollution Control Boards, MOEF

Demographic & Socio-economic Data
• Livelihoods• Land holdings• Population• Ecological hotspots• Water pricing
Geospatial Database Management
• For integration of information across domains– Processing raw data– Managing generated information– Storage– Retrieval
• Analysis to generate– Scenarios for different developmental pathways– Sharable information with all the stakeholders
