Groundwater Assessment in salboni block west bengal india using remote sensing geographical information system and multi criteria decision analysis techniques
Hydrogeology Journal, 2010Co-Authors: Madan K Jha, V. M. Chowdary, Alivia ChowdhuryAbstract:An approach is presented for the evaluation of Groundwater potential using remote sensing, geographic information system, geoelectrical, and multi-criteria decision analysis techniques. The approach divides the available hydrologic and hydrogeologic data into two groups, exogenous (hydrologic) and endogenous (subsurface). A case study in Salboni Block, West Bengal (India), uses six thematic layers of exogenous parameters and four thematic layers of endogenous parameters. These thematic layers and their features were assigned suitable weights which were normalized by analytic hierarchy process and eigenvector techniques. The layers were then integrated using ArcGIS software to generate two Groundwater potential maps. The hydrologic parameters-based Groundwater potential zone map indicated that the ‘good’ Groundwater potential zone covers 27.14% of the area, the ‘moderate’ zone 45.33%, and the ‘poor’ zone 27.53%. A comparison of this map with the Groundwater potential map based on subsurface parameters revealed that the hydrologic parameters-based map accurately delineates Groundwater potential zones in about 59% of the area, and hence it is dependable to a certain extent. More than 80% of the study area has moderate-to-poor Groundwater potential, which necessitates efficient Groundwater management for long-term water security. Overall, the integrated technique is useful for the Assessment of Groundwater resources at a basin or sub-basin scale.

An Integrated Approach of Hydrogeochemistry, Statistical Analysis, and Drinking Water Quality Index for Groundwater Assessment
Environmental Processes, 2020Co-Authors: Zahra JamshidzadehAbstract:Groundwater is the major source of water for different purposes in many parts of Iran. Therefore, its quality Assessment is of great interest. This research aims to consider the general conditions of Groundwater for drinking purposes in a coastal aquifer by using an integrated approach of hydrogeochemistry evaluation and drinking water quality index. Statistical results of major cations (Ca^2+, Mg^2+, Na^+ and K^+), major anions (HCO_3^−, SO_4^2− and Cl^−), pH, EC and TDS concentrations show that the abundant cations and anions are in the order of Ca^2+ > Na^+ > Mg^2+ > K^+ and HCO_3^− > Cl^− > SO_4^2−, respectively. Chadha plot and Piper diagram point out Ca-Mg-HCO_3 as the dominant Groundwater chemical types in all sampling points in the recharge zone (Zone A), and the majority of wells in the central zone (Zone B) and the coastline zone (Zone C). Na-Cl hydrochemical facies in the eastern part of Zone C is related to saltwater intrusion from the Caspian Sea or the upconing of underlying connate water. The ionic ratios reveal that rock weathering and mineral dissolution, evaporation, the overuses of fertilizers, and the upconing of paleo-saline water control the chemical evolution of Groundwater. The proposed drinking water quality index (DWQI) exhibits a poor quality of water in the north-east of the area, while the quality of Groundwater falls in the “good” class in the south-west of the area. Generally, the quality of Groundwater deteriorates from the south-west towards the north-east of the aquifer, and the eastern part of Zone B has the best quality of water for drinking purposes.

Approach to Groundwater Management towards Sustainable Development in India
Acque Sotterranee - Italian Journal of Groundwater, 2018Co-Authors: Y D Khare, Abhay M. VaradeAbstract:The management of Groundwater resources for sustainable development is a challenging task in India because of its vast geographical extent (3287000 km2), where about 1250 million people live. As a result, the Country is facing scarcity of drinking water quite often. This situation compels to adopt management practices for the development of sustainable Groundwater resources. The objective of the paper is to focus on need of adoption of appropriate management strategies for sustainable development of Groundwater resources. In view of this the Groundwater situation in India as reflected through published literature has been discussed, in which the causes of scarcity, aquifer situation, and Groundwater Assessment in India have been explained. Based on this study the future approach for Groundwater management to achieve the objective of sustainable development has been suggested. This paper provides insight to all the controlling factors affecting Groundwater resources in India. Based on this, suggestions for future implementation of water conservation programmes have also been discussed. The present study shows that despite availability of ample Groundwater resources the country faces drinking water scarcity quite often. This fact needs further analysis of scarcity situation to provide everlasting solution of problems related to Groundwater.

Insinuation of spatial database for realistic Groundwater Assessment in Indian context
Sustainable Water Resources Management, 2017Co-Authors: Abhay M. Varade, Y D Khare, N. C. Mondal, R. K. Deshkar, Shital ThakareAbstract:India is an agricultural-based country in which Groundwater is utilized on a large scale for irrigation. Groundwater resources are indiscriminately exploited causing problems of depletion of water tables. Under this situation, an accurate estimation of Groundwater resources in such regions, particularly the semi-arid regions, becomes imperative. In India, various line departments engaged in the Groundwater development activities carry out Assessment of Groundwater potential at periodic intervals. Such programs, many times, result into over/under-estimation of Groundwater resources due to non-consideration of spatial database reflecting the actual terrain conditions. Hence, the Groundwater development programs in such regions could not be planned precisely. To overcome this situation, an attempt was made to assess the Groundwater recharge and withdrawal affecting parameters in a watershed falling under Nagpur district of Central India through spatial database generated by remote sensing technique. For this study, the Groundwater resources of the study area were evaluated on the basis of GEC norm, which is a general practice in India, and also using spatial database controlling on factors like geology, geomorphology, land use/land cover, and hydrology, etc. The comparison in between Groundwater resources of the GEC norms and the approach through spatial database depicts a difference in recharge, recharge by return flow, worthy area, and withdrawal factors, etc. In this present case, the Groundwater estimation based on application of GEC norms indicated an additional scope of construction of new dug wells. However, the estimation carried out using spatial database indicates the over-developed nature of watershed leaving no scope for future development. Similar situations are expected in many watersheds elsewhere in the country. Therefore, there exists a need to revise the conventional Groundwater Assessment methodology by involving the spatial database, which will help in implementation of Groundwater development programs in the most effective and sustainable manner.

spatial analysis of impact of orange cultivation over Groundwater regime a case study of kolar watershed nagpur district maharashtra
Journal of The Indian Society of Remote Sensing, 2015Co-Authors: S V Muley, Pradeep Kundal, Yashwant B. Katpatal, Y D KhareAbstract:There is a common belief that the area under orange cultivation is increasing day by day in Vidarbha region of Maharashtra. It is posing threat to the Groundwater reserve, to the extent of its overexploitation, which is a matter of concern to the state administrators. In view of this, an attempt is made in the present study to analyze temporal variation in the area of orange cultivation for small part of Nagpur district by using high resolution satellite data. The impact of change in the cultivation area of oranges on Groundwater regime within the study area has also been analysed. Initially, the change detection study of the area has been carried out for the period 2003 to 2012 which shows that there is drastic reduction in the area under orange cultivation. This has also well reflected in the Groundwater Assessment as well as in the Groundwater table trends of observation wells. The study indicated that a balance between recharge and withdrawal of Groundwater has been achieved in the study area and Groundwater regime is stabilized over the period of study.
