Recharge and rainfall

This study evaluated the groundwater levels (GWLs) and groundwater quality of Can Tho city using statistical analysis and a Groundwater Quality Index (GWQI). In addition, the groundwater recharge potential from rainfall was investigated for the period 2001-2009.

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.

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.

Recharge basin structure having masonry spillway was evaluated in the experiment. The quantities of available runoff water under the maximum rainfall up to 5 consecutive days were estimated. Hydrograph was prepared by recording water level in the basin against time for duration of live storage period.

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.

Natural groundwater quality changes start in the soil, where infiltrating rainfall dissolves carbon dioxide from biological activity in the soil to produce weak carbonic acid that may assist removal of soluble minerals from the underlying rocks, e.g. calcite cements. At the same time, soil organisms consume some of the oxygen that was dissolved in the rainfall. In temperate and humid climates with significant recharge, groundwater moves relatively quickly through the aquifer.
