Soil Water Balance - an overview | ScienceDirect Topics

Dec 01, 2011 · The effects of climate on soil-water balance can be measured through the soil-water budget (Fig. 11.2), which is equal to the gain, loss, and storage of soil water in a column of soil (Thornthwaite and Mather, 1955; Strahler and Strahler, 1989). There are several components of the soil-water balance. Evapotranspiration (E) is defined in two ways.

Refinement of the Differential Water Loss Method for

Nov 01, 2006 · We have refined the differential water loss method by estimating the gypsum percentage from the loss of water in the soil sample between 70 and 90°C. Our results, compared with gravimetric determinations of precipitated BaSO 4, found coefficients of determination of 0.98 for gypsum contents ranging from 2 to 50%, and 0.99 for contents >50%.

Physical Processes Determining Water Loss from Soil

The water content, W, of surface layers of soil of thickness from 10 to 50 cm. were functions of time, T, that could be closely represented by equations of the form W = aT ‐b. This means that the rate of loss of soil water was inversely proportional to time after irrigation.

Selecting a Loss Method

The soil moisture accounting loss method uses three layers to represent the dynamics of water movement in the soil. Layers include soil storage, upper groundwater, and lower groundwater. Groundwater layers are not designed to represent aquifer processes; they are intended to be used for representing shallow inter-flow processes.

Soil erosion - Wikipedia

Soil erosion is the displacement of the upper layer of soil; it is a form of soil degradation.This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, animals, and humans.In accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, wind (aeolean) erosion, zoogenic
