Agricultural sector is the main consumer of our available water resources and demand of water in agricultural sector is continuously increasing. This study is an attempt to prepare a plan for proper utilization of groundwater of farm of Raipur campus of Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh. In watershed different components plays important role for recharging the groundwater such as rainfall, canal irrigation, bore well irrigation and ponds/tank irrigation.

Groundwater is an important source for irrigation in large tracks of India. This source has been considered as infinite and used indiscriminately without any disregard to recharge prospects. Reducing the over exploitation of ground water and its optimal utilization for irrigation is the need of the hour especially in low rainfall areas.

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.

Pennar is an important river of Ananthapuram district where 80 per cent of the district is drained by the river. Ground water levels were monitored from a network of 71 observation wells four times in a year. The depth to water level during pre-monsoon (2005) ranges from 2.53 to 19.67 m below ground water level. The shallow water levels of 10 m below ground water level are observed in majority of the district. Less fluctuation is observed in the areas where the water levels were comparatively shallow during pre-monsoon and where the slope is less.

Groundwater is one of the most valuable natural resources, which supports human health, economic development and ecological diversity. The amount of water that will ultimately arrive at the water table is defined as natural ground water recharge. The amount of this recharge depends upon the rate and duration of rainfall, the subsequent conditions at the upper boundary, the antecedent soil moisture conditions, the water table depth and the soil type.

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 present study was conducted to find status of water resource use and strategies for its future. The study was conducted in the five revenue districts of upper Narmada basin. In order to assess the status of water resource utilization in UNB first of all net ground water availability was computed, using annual recharge values. Methodology supported and recommended by G.E.C. (1997) was followed. Revenue blocks were taken as unit for assessment.

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.

Ground water withdrawal for irrigation, if not done correctly, leads to falling water table below critical level. In Madhya Pradesh, out of 313 blocks, 23 blocks extended to over exploited category, 09 blocks are in critical stage and 57 blocks are in semi critical stage (MP Dynamic Ground Water Assessment, 2015).

Groundwater is a dynamic and replenishable natural resource, but in hard rock terrains, availability of groundwater is of limited extent and is depleting in many areas due to its large scale withdrawal for various sectors. Groundwater recharge such as rainwater harvesting is essential in order to improve ground water level and quality. The main objective of the study is to identify suitable sites for groundwater recharge in the study area through Geospatial technology. To attain this Remote Sensing Technology is the good tool in mapping such geological features related to groundwater recharge.

The present investigation intends to examinations the morphometric attributes of Ozat River basin to comprehend the hydrogeological behavior and influence on hydrology of the basin. The basic and derived morphometric parameters (linear, areal and relief aspects of drainage network) for the basin were determined using ASTER DEM (30 m resolution),remotely sensed images of Linear Imaging Self Scanner III (LISS III) and Geographic Information System (GIS).

Water scarcity has many negative impacts on the environment, including lakes, rivers, wetlands, and other fresh water resources. Furthermore, water shortage makes flow management in the rehabilitation of village streams problematic. Owing to poor water resource management system and climate change India faces a persistent water shortage. Indian agriculture accounts for 90% water use due to fast track ground water depletion and poor irrigation systems. Water is a critical input into agriculture in nearly all its aspects having a determining effect on the eventual yield.

The study of geology, soils in the selection of sites for water spreading or infiltration recharging system are rather more important than for any well recharging systems. The basic aspects, which are considered, are: Moving the water through the vadose zone Making the water move through aquifer away from infiltration recharge sites so as to raise water buildup of ground water mound or ridge Therefore, for infiltration recharge systems the following area characteristics are desirable...
