Mine Closure Considerations in arid and semi-arid Areas

Even in arid and semi­ arid climates there is a potential that after completion of mining operations water will accumulate at the pit bottom and form a lake. Formation of the pit lake will depend on the balance betwe­ en surface and ground water inflow,

2. THE PROBLEM OF AGRICULTURE IN THE SEMI-ARID REGIONS

Wind erosion can be serious in the temperate semi-arid regions and examples are the central steppes of Asia (eastern USSR, Mongolia, and China); in North America the north-western States of the USA, and the central prairies of Canada. In the semi-arid tropics the picture varies.

Israel, for example, has expanded its water supply by some 7% by capturing rainwater and utilizing it for irrigation in arid and semi-arid regions (Tal, 2005). Yet, this supply is inherently given to periodic droughts and the quality of water may suffer from the salinization caused by evaporation. As the mining of ground water is a relatively recent phenomenon, its intrinsic un-sustainability ...

These arid soils are associated with constraints like low available water capacity, low nutrient retention and availability, vulnerable to wind erosion, shallow soil depth, salinity, sodicity and physical constraints like surface crust and high infiltration. Kind and magnitude of constraint may vary with the soil group.

Arid Region Landforms and Eolian Processes 18

As a result, while hillslopes in humid regions tend to be rounded and mantled by soil, mountains and hill slopes in arid regions are generally angular, with extensive, barren exposures of bedrock. Desert lowlands may be filled in with sediments eroded from uplands, or they may consist of just a thin cover of sediments overlying rock strata.

Phytostabization of mine tailings in arid and semi-arid ...

Many of these sites are found in arid and semi-arid regions of the U.S. where the associated problems differ from those in temperate regions. Specifically, acid mine drainage is of less importance while movement of tailings via eolian dispersion and water erosion is a much larger issue. The topic of this talk is phytostabilization, a low-cost extensive remediation approach for these types of ...

(PDF) Groundwater vulnerability to selenium in semi-arid ...

This is clearly seen in arid and semi-arid regions globally, where the high demand and scarcity of water enforce the use of alternative, less contaminated water. Selenium concentrations are highly variable in rock materials because of the dispersive nature of selenium, but its concentration rarely exceeds 0.1 mg/kg. The Se abundance in the Earth's crust is about 0.05-0.09 mg/kg (Adriano 1986 ...

Assessment and Management of Water Resources in

The mining of sub-marine groundwater is obviously unsustainable in the long term, but it may alleviate water shortages in regions where other sources of water are scarce or not (yet) available. This merits at least an exploration of its practical use, hydro-geologic potential and economic and environmental consequences. References. Bakken TH, Ruden F, Mangset LE

Characteristics of Arid Climates Sciencing

13/03/2018  A variety of factors combine to steer storms and moisture away from arid regions. In some arid climates, evaporation rates exceed precipitation, leading to a net moisture loss. In the hottest of arid climates, rain may evaporate before it can reach the ground. On the other hand, a torrential downpour may bring a short burst of life. Hot and Cold. Arid climates such

The human population in this semi arid region is small (less than 2% of the state) and geographically dispersed. The largest towns, Coober Pedy and Roxby Downs, are both associated with mining and are home to less than 5000 people, while the remaining scattered towns all have less than 1000 occupants. Pastoralism is the most dominant land use, with over
