Available Water Storage In Soil To 100cm Depth - Weighted Average This map service is an information surface representing the amount of available water storage (AWS) that is available to plants in the top 100cm (3.28 Feet) of soil. Available Water Storage (AWS) is expressed as centimeters of water, reported as the average of all components in the map unit. AWS is calculated from AWC (Available Water Capacity) which is commonly estimated as the difference between the water contents at 1/10 or 1/3 bar (field capacity) and 15 bars (permanent wilting point) tension, and adjusted for salinity and fragments. Available Water Storage (AWS) surfaces are available through arcgis.com for four soil depths, 25, 50, 100, and 150 centimeters from the surface of the soil. They are available...

Each component (and therefore soil map unit polygon) falls into one of the following classes according to NRCS: Very Poorly Drained, Poorly Drained, Somewhat Poorly Drained, Moderately Well Drained, Well Drained, Somewhat Excessively Drained and Excessively Drained. Of soil components which make up greater than or equal to 15% of the soil map unit, the wettest component is reported by the map service. Another service exists for drainage class which reports the dominant class in the soil map unit. The concept is similar but for some purposes knowing the dominant component may be...

Each component (and therefore soil map unit polygon) falls into one of the following classes according to NRCS: Very Poorly Drained, Poorly Drained, Somewhat Poorly Drained, Moderately Well Drained, Well Drained, Somewhat Excessively Drained and Excessively Drained. The class belonging to the component that makes up the highest percentage of the map unit is reported by the map service. Another service exists for drainage class which reports the wettest class in the soil map unit.

Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well...

Available Water Storage (AWS) is expressed as centimeters of water, reported as the average of all components in the map unit. AWS is calculated from AWC (Available Water Capacity) which is commonly estimated as the difference between the water contents at 1/10 or 1/3 bar (field capacity) and 15 bars (permanent wilting point) tension, and adjusted for salinity and fragments.
