The Water Erosion Prediction Project (WEPP), is a physically-based soil erosion prediction technology. WEPP has a number of customized interfaces developed for common applications such as roads, managed forests, forests following wildfire, and rangelands.
Vertical ecosystems enable plant species, fungi, and bacteria to live in an environment of almost unlimited resources, generating interactions favourable to the system.
stagnant. / (ˈstæɡnənt) / adjective. (of water, etc) standing still; without flow or current. brackish and foul from standing still.
Beneath the surface, water is transferred via throughflow, which is the movement of water through the lower soil towards rivers, and groundwater flow. Groundwater flow is typically very slow.
The Toxicity Characteristic Leaching Procedure (TCLP), which is used for determining whether a solid waste is a hazardous waste by exhibiting the characteristic of toxicity, is Method 1311. You can download a copy of Method 1311 from the EPA website. SW-846 is also available on-line at no cost from the EPA Website.
Thermal desorption removes organic contaminants from soil, sludge or sediment by heating them in a machine called a “thermal desorber” to evaporate the contaminants. Evaporation changes the contaminants into vapors (gases) and separates them from the solid material.
Consolidation of Soils | Terzaghi’s One-Dimensional Consolidation Theory. Consolidation is the process of gradual compression/settlement of soil due to the expulsion of pore water under steady pressure.
Its material and design also help reduce body heat loss. Thermal blankets are also most ideal in hospitals. Fever, perspiration, and many other factors cause body heat loss. They are also used by astronauts in space, in emergency kits, and for different military operations.
Vibro Stone Columns are one of the most commonly specified ground improvement methods in the UK. Given the correct soil conditions they can provide a relatively inexpensive and quick method of ground improvement. They can be used to provide an increase in bearing capacity and to improve settlement characteristics.
Cement Stabilized Soil (CSS): An engineered mixture of pulverized in-situ soil, water and moderate proportion of Portland cement, resulting in a semi bound to bound material, with engineering properties similar to an granular material. Will still provide improved soil shear and compressive strength.
