Abstract: The water present in the ground changes its levels for many reasons. The groundwater level mainly changes due to natural phenomena and human activities. A natural phenomenon refers to the precipitation and the infiltration of water, whereas manmade activities refer to groundwater used for the supply system of water. Some groundwater sources are heavily used for water supply, but some sources have very little use. Some wells are referred to as monitoring wells, which are used to maintain the records of the groundwater level fluctuation. This recorded data can be used for the detailed study of groundwater fluctuations. The data can be recorded at 30min intervals or on a daily basis. Daily basis recorded data is used for a long period of time. Also, water level changes can be referred to as short-term changes and long-term changes. Short term changes can be observed when the water level readings are recorded many times a day. While the long-term changes can be observed by the data collected for many years. There are so many factors that can affect water levels in the aquifer changes over time. The groundwater levels are majorly affected by the three main factors, 1) change in the volume of water available in the aquifer, 2) change in atmospheric pressure 3) Changes caused by aquifer deformation.
