Soil Creep Definition Soil Creep is a type of landslide that entails the slow and gradual movement of a soil mass (or even some loose rock) materials.

Hardpan (Caliche) “Hardpan” is a highly dense and solid layer of soil near the ground surface, which is usually comprised of clay or silty-clay soils. Hardpan forms by cementation over time, during the process of precipitation of insoluble substances such as calcium carbonates, silica, iron oxides, and other organic matter. “Hardpan” is a term mostly…

Hydraulic Head Hydrualic Head: In the field of hydrogeology, hydrualic Head is a measure of the potential energy of a fluid at any given point in a hydraulic system. It explains the potential energy driving fluid flow by summing the elevation of the fluid and the pressure it exerts.

Sedimentary Rock Definition In geology, the term “Sedimentary Rock” refers to the classification of rock that is the result of the gradual consolidation and deposition of loose particles of other rock classifications (igneous or metamorphic). Alternatively, sedimentary rocks can also form by the accumulation and precipitation of other natural chemical solutions in a depositional environment….

Design Methane Concentration Design Methane Concentration: In accordance with the Los Angeles Department of Building and Safety Methane Code, Ordinance Number 175790, a Design Methane Concentration is the highest recorded concentration of methane soil gas detected during the course of methane testing on a property. The Design Methane Concentration is what defines the level of…

Zeolites Definition In geology, zeolites are a group of hydro-alumino-silicate minerals that are compositionally analogous to the feldspars. Zeolites typically comprise sodium (Na), calcium (Ca), or potassium (K) as chief metals. And zeolites also tend to develop within basalt cavities, lake sediments, oceanic sediments, and volcanic tuff. Modern Economical uses of the Zeolites Modernly, zeolites…
