The removal of vegetation damages the microclimate by removing shade and reducing humidity. It also contributes to global climate change by diminishing the capacity of the vegetation to absorb carbon dioxide. Land clearing could also be responsible for reduced rainfall levels & possible desertification of land as well as soil erosion. [citation ...
Dawesville Channel (also known as Dawesville Cut) is an artificial channel between the Peel-Harvey Estuary and the Indian Ocean at Dawesville, about 80 km (50 mi) south of Perth in Western Australia. It is south of the regional city of Mandurah and north of Yalgorup National Park .
Although it is rarely used alone, plants can flourish from mixed soil that includes a mix of compost with other additives such as sand, grit, bark chips, vermiculite, perlite, or clay granules to produce loam. Compost can be tilled directly into the soil or growing medium to boost the level of organic matter and the overall fertility of the soil.
Soil compaction is a vital part of the construction process. It is used for support of structural entities such as building foundations, roadways, walkways, and earth retaining structures to name a few. For a given soil type certain properties may deem it more or less desirable to perform adequately for a particular circumstance.
Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless". [2]
The removal of volatile organic compounds from the soils can increase the soil vapor concentration. Counterintuitively, highly permeable soils lower the efficiency of electrokinetics. Where a low permeable soil like clay can receive up to 90% initial contaminant removal a low permeable soil like peat achieves about 65% removal of initial ...

The depth of the dry well allows the water to penetrate soil layers with poor infiltration such as clays into more permeable layers of the vadose zone such as sand. [7] [8] Simple dry wells consist of a pit filled with gravel, riprap, rubble, or other debris. Such pits resist collapse but do not have much storage capacity because their interior ...
