Groundwater is a better long-term water supply option when the weather is dry. An evaluation, development and suitable usage of it should be given more attention. In dry and semi-arid locations, groundwater is the primary source of water. Groundwater management becomes much more difficult in these places since there is a dearth of data. In order to determine how much groundwater may be used, groundwater recharge is critical to the process. Groundwater recharge rates have been studied extensively using a variety of approaches. This page offers an overview of the criteria that have been accepted and how they affect the outcomes. A review of previous research on methods for calculating the quantity of groundwater recharged, as well as an explanation of the features of each approach, is then presented. Prior research focused mostly on the geology and slope of the land, soil, land use/cover, lineaments, and drainage. The water table fluctuation (WTF) approach was determined to be the most widely employed method in the prior research evaluated. There is a high degree of accuracy in the data, although digging wells in the region is required to determine the depth of the ground water. In addition, it is considered the soil water balance method, a common method, and it gives accurate results and does not require drilling wells in the study area. It is the goal of this study to advise on the most appropriate methods for future groundwater recharge research. A multi-method strategy has been shown to be effective in much prior research in order to obtain more robust results and compare data collected at various scales. [ABSTRACT FROM AUTHOR] |
