WELLS. All wells in confined aquifers are considered artesian wells. If the elevation of the potentiometric surface is above than the elevation of the land surface, groundwater will flow naturally (without pumping) from the well, known as a flowing artesian well. RECHARGE. Recharge to unconfined...
Issues in Groundwater Lesson Summary Register to view this lesson Are you a student or a teacher? FAQ What are the two types of groundwater? The two types of groundwater are aquifers and wells. Aquifers are underground areas that contain rock and other materials that are permeable, allowing ...
A pump test consists of pumping a well at a certain rate and recording the drawdown (decline) of water level in the pumping well and in nearby observation wells over a certain time period. The responses of the water levels at and near the pumping well reflect the aquifer's ability to tra...

The self-calibrated PDSI (sc-PDSI) proposed by Wells et al. (Wells et al., 2004) (2004) significantly improves the spatial comparability of the PDSI. The sc-PDSI can quantitatively determine the severity of a long-term drought at a given location and time, so using it to study and ...
Earlier works suggest that the floodplain geomorphology has a close association with arsenic (As) contaminated tube wells. However, the association of As-contaminated tube wells and the Land Use Land Cover (LULC) categories is not clear. The focus area o
In this chapter, we review the level of disturbance caused by railways due to noise and vibration, air, soil and water pollution, and soil erosion. There is evidence that soil and hydrology contamination may affect vegetation and aquatic fauna while noise can affect terrestrial vertebrates. In fa...

All of these sites relied on shallow land burial technology in which the waste was placed in trenches and covered with earthen material. Experience from these facilities has highlighted the significance of local geology, hydrology , and site engineering in the performance of disposal facilities. ...
Measurements of hydrology were made using maximum-minimum water level recording wells at each fen. The frequency of water levels within the root zone was determined and compared. Fen landscape position was analyzed with respect to slope face (aspect), slope angle, elevation, stand relief, and ...
