Determine which of the following particles make up the majority of the soil (if any): sand, silt, clay: the choice of loam indicates that the soil is composed of roughly equal amounts of clay, silt, and sand. This field can be autofilled via the Autofill button, in the U.S.
The amount of rocks visible on the surface of the hillslope. This field can be autofilled via the Autofill button, in the U.S.
The horizontal change in the position from the bottom to the top of the hillslope, in feet.
The slope is the change in vertical position over the change in horizontal position from the bottom of the hillslope to the top. The slope gradient is the percentage of slope, or slope x 100. This field can be autofilled via the Autofill button, in the U.S.
Choose the best description of the vegetation concentration of the hillslope.
Describe the percentage of the hillslope soil, which is covered by natural ground covering (vegetation, dead plant material, rocks, etc.). The coverage of a hillslope can be estimated by taking 20 steps accross the hillslope and counting how many times you step on natural ground covering.
Select the location, which is closest to you. The list is of climate stations, each of which is defined by the location of the station.
Input the number of years between 1 and 200, for which to run the model.
