      In semiarid and arid environments, leakage from rivers is a major source of recharge to underlying unconfined aquifers. Differential river gauging is widely used to estimate the recharge. However, the methods commonly applied are limited in that the temporal resolution is event‐scale or longer. WSP / Nichols, W.

The main area of interest, approximately mi2 ( km 2) of semiarid agricultural and rangeland in the southern Raft River Simulation analysis of the unconfined aquifer that includes the known Geothermal Resource Area near Bridge, Idaho, was modelled numerically to evaluate the hydrodynamics of the unconfined aquifer.

The Raft River geothermal project is now complete, with Unit 1 producing up to 10MW. Raft River is in southern Idaho, US, about miles south-east of Boise, at a former US Department of Energy (DOE) geothermal site.

US Geothermal plans to produce up to 36MW from the site. For the groundwater flow analysis using the MFree PCM model, a case study of regional aquifer modeling is presented here. An unconfined aquifer in Pochampad Ayacut, Andhra Pradesh, India is considered to determine the effects of continued pumping on the regional groundwater basin.The aquifer considered has a specific area of 67 km aquifer is wedge shaped bounded by two.

The Raft River geothermal site is located in the Raft River Valley in southeastern Idaho, miles northwest of Salt Lake City, Utah. It was designated a Known Geothermal Resource Area in by the U.S. Geological Survey, and a geothermal demonstration plant was operated there from late to June (Covington, ).

Description: This study undertaken to define quantitatively the geohydrologic properties and hydrodynamics of the shallow aquifer system in the southern Raft River Valley and to determine if there is any significant hydrodynamic interdependence between.

In the base simulation the unconfined and confined aquifer boundaries are set at a constant head of m.

Horizontal groundwater flows in unconfined aquifers with horizontal lower boundaries can be found exactly by the seepage analysis that allows the hydraulic conductivity to vary in the vertical direction.

The exact analysis of flows when the lower boundary of the aquifer is not a horizontal plane, requires the soil-water pressure on this boundary to be known, and this is not generally the case.

The Raft River area was designated a Known Geothermal Resource Area (KGRA) inand in the United States Geological Survey (USGS) and Energy Research and Development Administration (ERDA, now the Department of Energy (DOE)) began a geothermal exploration program in southern Idaho (Fig.
