Water table fluctuation

The present study attempts to determine groundwater recharge of the two over exploited blocks of Karur district in Amaravathy basin viz., Aravakurichi and K. Paramathi by water table fluctuation method. Rainfall data of eight rain gauge stations for 30 years (1982- 2012) and water level data of twenty three stations were collected from the office of State Ground and Surface Water Resources Data Centre, Tharamani, Chennai for analysis.

Various quantitative analyses are required for complex and dynamic nature of water resources systems to manage it properly. Groundwater table fluctuations over time in shallow aquifer systems need to be evaluated for formulating or designing an appropriate groundwater development scheme. This paper demonstrates a methodology for modeling rainfall- runoff and groundwater table fluctuations observed in a shallow unconfined aquifer Gonda District Utter Pradesh.

The Indo-Gangetic plains comprise of large floodplains of the Indus and GangesBrahmaputra river systems. They are home to approximately 1 billion people and encompass northern and eastern India, much of Bangladesh, parts of southern Nepal and the most populous parts of Pakistan. Ground Water remains the lifeline of socioeconomic development in the Ganga Alluvial Plain (GAP) since the down of civilization in the Indian subcontinent.

The water availability is limited, however demand of water is increasing many fold due to expansion of agriculture, growing population, rapid industrialization and economic development in India. Available water resources need to be managed properly to meet increasing demands of water. In this study, different hydrological processes as surface runoff, evapotranspiration and soil moisture were modeled to assess the groundwater recharge in a small watershed located in semi-arid region of Rajasthan, India.

The study was undertaken based on the recommendation of groundwater estimation committee, 1997 (GEC-97). Methodology used the estimation of annual groundwater recharge from rainfall and other sources, including irrigation, water bodies and artificial recharge, determination of present status of groundwater utilization and categorization of assessment units based on the level of groundwater utilization and long-term water level trend. Water level fluctuation techniques and empirical norms were used for recharge estimation.
