    Oct 24,  · The water levels in aquifers is not often a constant. Groundwater levels first are dependent on recharge from infiltration of precipitation so when a drought hits the land surface it can impact the water levels below ground, too. Likewise, many aquifers, especially those which don't have abundant recharge, are affected by the amount of water being pumped out of local wells. Evaluation of Methods for Delineating Areas That Contribute Water to Wells Completed in Valley-Fill Aquifers in Pennsylvania By Dennis W. Risser and Thomas M. frecklesandhoney.com by: 4.

    This report by the U.S. Geological Survey, prepared in cooperation with the Pennsylvania Department of Environmental Protection, Bureau of Mining and Reclamation, evaluates factors affecting the application of specific-capacity tests in six low-yielding water wells in areas of coal mining or quarrying in Pennsylvania.

Areas contributing recharge to wells. Simulation techniques are used to calculate the areas contribut-ing recharge under a variety ofconditions defined for hypothetical aquifer systems. The areas contrib-uting flow to wells as determinedfor the hypotheti-cal systems are delineated in a series offigures.

The use of simple hypothetical systems provides the. Factors Affecting Areas Contributing Recharge to Wells in Shallow Aquifers. Factors Affecting Areas Contributing Recharge to Wells in Shallow Aquifers U.S. Geological Survey, Water Supply Paper by Thomas E. Reilly and David W. Pollack. This report is available as a pdf below.

The calculation of areas contributing recharge to wells is complex because flow paths in ground-water systems change in response to development, and the aquifer material in ground-water systems is heterogeneous and is hidden from direct observation.

A series of experiments conducted at a research site on Cape Cod, Massachusetts, examined the effects of. Recharge and groundwater models: An overview. Hydrogeology Journal, 10, the delineation of areas contributing recharge to wells and the estimation of paleorecharge rates using carbon.

The highly permeable, unconfined, glacial drift aquifers that occupy most New England river valleys constitute the principal source of drinking water for many communities that obtain part or all of their public water supply from groundwater. Analytical, two-dimensional numerical and three-dimensional numerical models were used to delineate contributing areas of groundwater pollution.

Recharge is a major component of the ground-water system and has important implications for shallow ground-water quality. Recharge commonly is estimated at the watershed scale using simple water-budget methods or numerical ground-water flow models. Whereas these methods provide an average recharge estimate for an area, recharge can vary.

Nov 06,  · Factors affecting infiltration A future hydrologist studying groundwater infiltration. Fido assists by making depressions in the ground to demonstrate how small depressions in the ground can accumulate water, which then can sink into the ground ane recharge groundwater.

Groundwater recharge, or deep drainage, is the process in which water percolates from the surface down into the groundwater supplies. Recharge does occur naturally, but it can also be achieved through anthropogenic methods, called artificial recharge.

In artificial recharge, surface water is rerouted to the subsurface. Factors affecting CO2 storage capacity and efficiency with water withdrawal in shallow saline aquifers Article in Environmental Earth Sciences 71(1) · January with Reads. Understanding factors affecting 1,2,3-TCP will aid in determining vulnerability and long term persistence in the San Joaquin Valley, which can help focus efforts to manage drinking water resources on the most vulnerable areas and also inform efforts in other areas of the state and frecklesandhoney.com by: 2.

Aquifer recharge, storage, and recovery are used to replenish aquifers for future use such as storing water in the ground and recovering the water from the same reinjection well.

Treated coalbed gas co-produced water can be used to recharge groundwater aquifers, which may impact drinking water standards. Oct 27,  · The velocity can be affected by many factors such as the narrower the river the faster the river will flow.

There can also be debris in the river which will also affect the velocity and is the gradient is steeper then the river will also flow faster. Chapter 2: Aquifers and groundwater Two factors affect how an aquifer conveys water: its hydraulic conductivity and hydraulic gradient (see diagram below).

These aquifers receive recharge at a rate of 80, ML/ yr and they are being pumped at a rate ofML/yr. This. The distinction of recharge area, intermediate area and discharge area with the groundwater recharge rates of90 and 80 mm yr −1 respectively have been simulated during the model calibration.

The recharge in alluvial plains of the Godavari River was reduced to Cited by: We report on an application of an analytical method to determine the groundwater velocity in aquifer recharge areas. Th e methodology is based on the analysis of aquifer temperature measures. Introduction.

Shallow aquifers can provide a valuable source of water (Karunaratne and Pathmarajah,de Silva,Villholth and Rajasooriyar,Foster, ); large diameter wells (typically 3–8 m in diameter) are often used to withdraw water from these aquifers (Rushton, ).Shallow aquifers occur due to weathering in hard rock areas; this is the main setting for this Cited by: 2.

Feb 06,  · In addition, groundwater depletion occurs at scales ranging from a single well to aquifer systems underlying several states. The extents of the resulting effects depend on several factors including pumpage and natural discharge rates, physical properties of the aquifer, and natural and human-induced recharge rates.

Some examples are given below. Thomas E. Reilly has written: 'Factors affecting areas contributing recharge to wells in shallow aquifers' -- subject(s): Groundwater flow, Aquifers 'Guidelines for evaluating ground-water flow.contributing area if precipitation on the carbonate-rock aquifer surface were the only source of recharge.

However, because a stream that flows from the adjacent crystalline-bedrock uplands loses water to the aquifer as it crosses the area of diversion to the well, the contributing area of the well Cited by: 2.Groundwater Flow to Wells Hsin-yu Shan Department of Civil Engineering National Chiao Tung University.
