6 Hour Distribution Defaults The selection of 6 Hour Distribution Defaults from the Hydrology\Rainfall menu is used to edit the default values for the rainfall patterns. The values should only be modified with caution as the default values are published by the County. Soils Data The selection of Data from the Hydrology\Soil menu is used to add or edit soil data required for the Sub Basins. The important values to enter are the Sub Basin ID which must match a Sub Basin ID in the Sub Basins Table, a Map Unit code, which will come from the Soil Defaults and the area for this soil. All of the remaining values can be calculated using the button. KVL Consultants, Inc. 4-2 Drainage Design Management System – User’s Manual 92-38.doc
There are three columns in the Soil Parameters section of the form. The first column, Value, is the value that will be used in the modeling analysis. The second column, Calc’d, is the calculated value based on the soil default values. The third column, Custom, ensures that a user entered value will not be overwritten with the calculated value when updating data. Defaults The selection of Defaults from the Hydrology\Soil menu is used to add or edit soil defaults required for the Sub Basins. It is important to enter appropriate values for all fields as soil calculations for the entire project will be based on these values. When first entering this form for the project, if soil default data does not exist, the County’s default data is loaded into the system. Soil Surveys The selection of Soil Surveys from the Hydrology\Soil menu is used to add or edit soil surveys. This data is used to filter data on the Soil Data form.
