Need of Water Resources Data for Stakeholders v Karnataka is one of the most water-stressed and drought prone State v Urban water supply demands increasing – competing from same source (surface water) v Rural communities dependence on SW for drinking increasing v Demand for water by the non-agriculture sectors is rapidly increasing v Long-term warming trends and negative trend in rainfall with changed pattern v Data and information on water resources is collected and archived by various agencies Advanced Centre for Integrated Water Resources Management Water Resources Department, Government of Karnataka 5

Karnataka Water Resources Information System (KWRIS) KWRIS - A spatial system bringing together: • Quantity and Quality • Surface water, Groundwater and water dependent ecosystems Advanced Centre for Integrated Water Resources Management Water Resources Department, Government of Karnataka 6

FUNCTIONAL MODULES Advanced Centre for Integrated Water Resources Management Water Resources Department, Government of Karnataka 7

ARCHITECTURE v Database is in three parts: a) de-normalised database for storage b) normalised database for rendering quick statistics and dashboards; c) Metadata which indicates data availability v Single sign-on security authentication scheme and v Web portal solution, OGC certified WMS, WFS, WRS web services Advanced Centre for Integrated Water Resources Management Water Resources Department, Government of Karnataka 8

CURRENT DEVELOPMENT CONTINUED… Advanced Centre for Integrated Water Resources Management Water Resources Department, Government of Karnataka 10

CURRENT DEVELOPMENT v. Data sources are clearly identified v. Data warehouse has been constructed v. Security audit completed and hosting on e-Governance server v. Login provided to all departments v. Data availability is visible through a catalogue v. Key parameters are available on the dashboard v. Dissemination in multiple formats v. Functional GIS enabled system to better select information of relevance on a spatial basis Advanced Centre for Integrated Water Resources Management Water Resources Department, Government of Karnataka 11

FURTHER DEVELOPMENT The stake holders have been consulted and following major Decision Support tools identified for development : v GIS enabled Ground Water tool for data analysis and reports v Hydrological modelling tool for yield estimation, no proprietary software v Water Budgeting tool for water budgets at GP level, spatial and non-spatial data CONTINUED… Advanced Centre for Integrated Water Resources Management Water Resources Department, Government of Karnataka 13

FURTHER DEVELOPMENT v Watershed management tool for improved water conservation planning and natural resource management v Flow forecasting tool flow estimates for any point of interest v Reservoir management tool to understand status of reservoir, rainfall, forecast v Data interoperability APIs to disseminate data across states for any regulatory purposes CONTINUED… Advanced Centre for Integrated Water Resources Management Water Resources Department, Government of Karnataka 14

FURTHER DEVELOPMENT The following tools will also be integrated into KWRIS which would be beneficial to user departments: a) Crop stress models b) Hydrological Monitoring & Prediction (Drought & Floods) c) Water Accounting & water productivity using RS & GIS d) Water body extent estimation using RS & GIS e) Crop advisories, Pest advisories, Crop maps Advanced Centre for Integrated Water Resources Management Water Resources Department, Government of Karnataka 15

CHALLENGES… Advanced Centre for Integrated Water Resources Management Water Resources Department, Government of Karnataka 16

Raw Data – Irrigation Processed– Irrigation Advanced Centre for Integrated Water Resources Management Water Resources Department, Government of Karnataka 17

Data Processing - Rainfall Data received with Lat/Long locations and readings Advanced Centre for Integrated Water Resources Management Water Resources Department, Government of Karnataka 18

Soil Data Processing - Vectorisation • Data in PDF format Advanced Centre for Integrated Water Resources Management Water Resources Department, Government of Karnataka 19

CONCLUSION v. Getting water data right is a major challenge requiring cautious planning, investments and implementation strategies v. Water data information systems will be most effective when implemented with functionality, maintainability, spatial enablement and dependability v. Absence of common data formats, lack of stakeholder involvement, telemetry instrumentations maintenance are the key concerns in keeping the system updated. v. WATER Information is the key for all life and livelihood systems that derive economic good and a healthy society Advanced Centre for Integrated Water Resources Management Water Resources Department, Government of Karnataka 20
