Water retention curve is the relationship between the water content, θ, and the soil water potential, ψ. The soil moisture curve is characteristic for different types of soil, and is also called the soil moisture characteristic. It is used to predict the soil water storage, water supply to the plants (field capacity) and soil aggregate stability.
Water retention on a random surface of 10 levels. Water retention on five levels. One system in which the retention question has been studied is a surface of random heights. Here one can map the random surface to site percolation, and each cell is mapped to a site on the underlying graph or lattice that represents the system.
Pores (the spaces that exist between soil particles) provide for the passage and/or retention of gasses and moisture within the soil profile.The soil's ability to retain water is strongly related to particle size; water molecules hold more tightly to the fine particles of a clay soil than to coarser particles of a sandy soil, so clays generally retain more water.

A typical water quality model consists of a collection of formulations representing physical mechanisms that determine position and momentum of pollutants in a water body. [4] Models are available for individual components of the hydrological system such as surface runoff ; [ 5 ] there also exist basin wide models addressing hydrologic ...
In subsea geotechnical engineering, seabed materials are considered a two-phase material composed of rock or mineral particles and water. [ 18 ] [ 19 ] Structures may be fixed in place in the seabed—as is the case for piers , jetties and fixed-bottom wind turbines—or may comprise a floating structure that remains roughly fixed relative to ...
Water weight, also known as water retention, is a buildup of excess water or fluid in the body's tissues, which can occur for a variety of reasons, Dr. Felice Schnoll-Sussman, gastroenterologist ...
Because of evaporation, interception of liquid water generally leads to loss of that precipitation for the drainage basin, except for cases such as fog interception, but increase flood protection dramatically, Alila et al., (2009). [3] Definition of canopy and forest floor interception
Model of a port structure loaded on the UC Davis centrifuge. A geotechnical centrifuge is used to test models of geotechnical problems such as the strength, stiffness and capacity of foundations for bridges and buildings, settlement of embankments, [6] stability of slopes, earth retaining structures, [7] tunnel stability and seawalls.
