------------------------------------------------------ EPA SWMM 5 Build 5.0.022 (04/21/11) ------------------------------------------------------ Engine Updates 1. The following fixes and updates were made to the LID module of the code (lid.c): a. The Drain Delay time for a Rain Barrel LID is now correctly converted internally from hours to seconds. b. The meaning of the Conductivity property of an LID's Storage layer has been changed. It is now defined as the saturated hydraulic conductivity of the native soil below the layer instead of the conductivity of the layer itself. c. Storage layers are now optional for Bio-Retention Cells and Permeable Pavement LIDs by allowing the layer height to be zero. One should still enter a non-zero conductivity for the layer if infiltration into native soil is allowed. d. If the top width of the overland flow surface for an LID is zero then any excess water above the surface storage depth simply spills out instantaneously. e. The calculation of i...
