The area under study is devoid of dependable and or sustainable irrigation facility. Surface water irrigation facilities in the form of minor irrigation tanks locally termed as cheruvu, in the area are dry for the last 4–5 years due to continuous chronic drought condition in the area. Hence the agricultural sector is mainly dependent on groundwater for sustaining the basic need for cultivation, during pre monsoon periods. Survey on well inventory in the study area revealed few tens of open wells, large number of dug-cum-bore and bore wells drilled up to the maximum depth of 80 m. Yield test carried out for dug-cum-bore and bore wells were not prospective in more than 50% of the cases due to the occurrence of massive rocks and dry fracture zones. The study area has three bore wells [BW1, BW2, and BW3] drilled 60 m, 55 m and 58 m respectively, trending NNW and SSE direction along the course of the rivulet, as shown in.

Recent Global Research Developments in Advancements in Groundwater Exploration Techniques: Insights from Granite Terrain
Exploration and Sustainable Management of Groundwater Resources in Geologically Complex Terrain [1]:
- This special issue in the journal “Applied Sciences” focuses on groundwater resources in complex geological environments.
- The articles cover topics such as groundwater investigation, monitoring, numerical modeling, climate change’s impact on groundwater resources, subsurface processes, and sustainable management strategies.
- Notably, one study investigated the spatiotemporal characteristics of groundwater level variation in Taiwan’s mountainous areas, contributing to a better understanding of groundwater dynamics and fluctuation potential in complex aquifer systems.
Advances in Groundwater Potential Mapping [2]:
- This review paper discusses groundwater potential mapping, an explorative technique based on remote sensing and geographical databases.
- The field has experienced significant developments in recent years, making it a valuable resource for assessing groundwater potential.
Geophysical Methods for Assessing Groundwater Extraction Sites [3]:
- Geophysical methods, including P-wave measurements and resistivity techniques, help assess potential groundwater extraction sites.
- These methods provide valuable information about aquifer properties and aid in sustainable groundwater management.
