Playas replenish the Ogallala Aquifer, a 948-trillion-gallon underground body of water that underpins agriculture in an eight-state region. Though these little wetlands comprise only 2 percent of the land area in the southern plains, they are the primary source of recharge for the Ogallala, which in turn sustains irrigation of the High Plains ...By inverting both real and predicted datasets, it is possible to define a dynamic model of time-space evolution of the water plume contaminated by a tracer injected into the aquifer system(s).Groundwater supplies approximately half of the total global domestic water demand. It also complements the seasonal and annual variabilities of surface water. Monitoring of groundwater fluctuations is mandatory to envisage the composition of terrestrial water storage.

An aquifer is a natural underground geological formation where large quantities of ground water fill spaces between rocks and sediment. To be considered an aquifer in Idaho, the geological formation must produce economically significant quantities of water to wells and springs. There are about 70 major aquifers in Idaho. Types.

The Mereenie Sandstone is the most extensive aquifer in the Amadeus Basin sequence, underlying 26,000 km 2 of Central Australia. The sandstone is up to 1000 m thick and is of late Ordovician to early Devonian age and mainly of aeolian origin.It outcrops around the margins of several large synclinal structures (Fig. 2).In the largest syncline, …

Regarding limitations of the research, the main problem is acquiring the right data and information for capturing the real aquifer behaviour (Response). For that, it is crucial to select very well studied boreholes (observation wells) that are exclusively affected by rainfall. That may be a handicap for generalizing this research. 6. Conclusions

These aquifers are a critical source of water for Texas, supplying 55 percent of the 14.7 million acre-feet of water used in the state in 2020. About 75 percent of this water is used for irrigation, with irrigators withdrawing most of this water from the Ogallala Aquifer alone (74 percent of all groundwater used for irrigation, or 4.5 million ...Two qanat systems are shown here, one in a standard aquifer and the other in a real test case, namely Haji-Abad qanat, located in the Birjand unconfined aquifer.

In a real aquifer, there would be nonhorizontal flow components near the water table and near ABC. However, making the Dupuit-Forchheimer assumption of a horizontal flow pattern, satisfactory results are obtained for the discharge when the water table slope is small and the variation in the unconfined aquifer depth relative to that depth is small.Solution.
