  8. Purpose Driven Study

  9. Pilot Project on Aquifer Mapping was taken up under Purpose Driven Study component in six different Hydrogeological terrains of the country. Pilot Project on Aquifer Mapping

  10. Pilot Project on Aquifer Mapping – Progress • Collection and Compilation of existing data completed. • Various thematic layers prepared. • Identification of data gap completed. • Additional data generated using hydrogeological and geophysical techniques to fill the data gap. • Water Level Data • Water Quality Data • Ground Water Exploration data through drilling • Determination of Aquifer parameters through Pumping test • Generation of Geophysical Data using Ground and Heliborne survey through NGRI as consultant • The integration of geophysical & hydrogeological data is under progress. • On the basis of hydrogeological data, conceptualization of aquifer system has been made for all pilot areas. Modeling through simulation is under progress.

  11. NGRI Geophysical Progress

  12. Pilot Project on Aquifer Mapping – Preliminary Findings • 2D & 3D aquifer disposition have been envisaged on the basis of Conceptual model. Different Aquifer systems have been demarcated. • Bihar – Three Aquifers delineated and Palaeochannel have been characterized. • Maharashtra - The zones of each flow depicting intertrappean, weathered and compact basalt could be identified and Gondwanas & Basalts have been precisely demarcated. • Tamil Nadu - Four aquifer systems have been clearly indicated in Pilot area of Tamil Nadu; Palaeochannel showing fresh water aquifer comprising of coarse sand is seen at the depth of 100-110 m running N-S and occurrence of limestone at shallow depth along the coast at places may indicate fault. • Karnataka - Potential zones identified at select locations. • The project is under progress and integration of results would bring out the refinement in sub surface disposition of aquifer; the efficacy of different techniques and protocol for use of Geophysical methods.

  20. Pilot Project on Aquifer Mapping – Payment to NGRI

  21. Programme for 2014-15

  22. Lessons Learnt • From the experience of the scheme, following suggestions are made • Since the HP-I and HP-II was not implemented in few states, there is a need of upscaling the three major components of HP-II through strengthening of State Ground Water departments by improving of institutional and organisational arrangements

  23. Post project plan for continuation of HP2 activities Introduction of e-GEMS to non-HP states on mutual consent of respective state governments Development of Standard protocol for use of geophysical techniques for aquifer mapping from the results of Pilot Project on Aquifer Mapping, which will be used for National Aquifer Mapping programme. Transfer and dissemination of hydrological and water quality data for basic water resource evaluations between central and all the state agencies

  24. Dissemination data and application of HIS • Application of HIS: • Following reports have been published using HIS data: • State Report - Regional Groundwater Scenario depicting the occurrence, development potential and management options for groundwater resources of the state • District report - Groundwater Scenario & formulation of sustainable groundwater development Strategy at the district level • Ground Water Year Books - Groundwater Year Book for each region & Groundwater Year Book consolidated for the country are published every year • Groundwater Estimation Report as in 2004, 2009 & 2011 by each States - Assessment of Groundwater resources for each state • Water Supply Investigation report - Feasibility report for sustainable groundwater development • Groundwater Exploration Report - Summary of exploration carried out by Central Ground Water Board • In addition, application of HIS data in Artificial Recharge Scheme formulation and water quality investigations.

  25. Dissemination data and application of HIS Data Dissemination: Data disseminated to various Central and State government departments, Central & state universities and research students for different academics and scientific investigations.

  26. A Journey from Ground Water Development to Aquifer Management Thanks Pilot Project on Aquifer Mapping

  27. HP III • Proposed Activity for Hydrology Project III • Up-scaling to Other States • Institutional Strengthening • Procurement of Hydrogeological equipment • Procurements of Geophysical equipment • Procurement of software • Procurement of chemical equipment: • (B) Vertical Extension • Identification of the issues related to public concern in water management in the existing states. • Hydro-geological support data collection at micro level • increased frequency of water level monitoring • Compilation and Integration of existing data HP III
