The Vision of the Regional Centre
About 67% of India is occupied by hard rock terrain. This region is frequently experience drought and at times flood. The ground water is one of the most depended water resources in the region. Over last decade, the usage of ground water has increased exponentially causing the lowering of water level. On the other hand, increased anthropogenic activities in region has resulted in a dramatic changes in the land use and land cover. This has strongly affected the water availability of the region. These problems are further complicated by the changes observed in the rainfall and meteorological parameters over the region. In order to study the effect of these changes on the water availability of the hard rock region, the following are the thrust areas, viz., forest hydrology, groundwater, and water logging and salinity studies being focused. However, looking at the present and future need of the region, drought studies, urban hydrology and the impacts of climate change on water resources sector were added. Apart from this, technology transfer activities, extension services/mass awareness programmes, infrastructure development, improvement of laboratories and establishment of experimental watersheds/plots were given importance in the future plans of the Centre.
The regional centre is actively involved in conducting field based studies for many years. In continuation of its previous efforts to generate the first hand data for inferring more insight into the problem, the regional centre is engaged in many research studies such as Basin Level Planning of Manimanla River Basin in Kerala, Estimation of Environmental Flow Requirement of Bhadra River in Karantaka and Assesment of Efficacy of Artificial Recharge Structure in augmenting the ground water in semi-arid zone of Karnataka.
Keeping in view of growing problem of water deficit in the region, which is compounded by the present problem of climate change, it is imperative to assess the possible impact of climate change on the water resources of the region. In order to meet this objective, a study has been proposed to carry out the analysis of climate change and its impact on the water availability in the Western Ghat region of India.
Interaction with other organizations
The Regional Centre collaboratively taken-up a Purpose Driven Study (PDS)) with Kerala Irrigation and Ground Water departments to assess the water quality over entire state. Also, a PDS study is being proposed along with Karnataka State Water Resource Development Organization for optimizing the Stream Gauge Network in Karnataka. In addition to these PDS studies, the regional Centre is actively engaged with the DST to study the impact of land cover changes on water balance component of forested watersheds in Western Ghats. The Following departments are regularly interactingf with the Regional Centre for conducting studies on hydrological problems of the region and for exchanging information and data: Karnataka Irrigation Department, APERL Hyderabd, Maharashtra Irrigation Department, Ground Water Department Tamilnadu, Institute of Water Studies Taramani, Chennai, University of Agricultural Sciences Dharwad, AP Irrigation Department, CWC Hyderabd, Ground Water Department Hyderabd, NRDMS Belgaum, CGWB, Department of Mines and Geology, GIT Belgaum, KLES CET Belgaum, KREC Mangalore, WALMI Dharwad, Karnataka University, Dharwar, SDMEC Dharwad. GSDA Pune, KPCL, etc.
