Abstract

Engineers design a substantial fraction portion of infrastructure that accommodates storm water drainage and conveyance. Estimation models of the response for a watershed typically contain some form of watershed slope as a principal parameter, and the response is usually inversely proportional to that slope. Therefore, as topographic slope decreases, the watershed timing parameter increases. The consequences at low enough slope, is that the timing parameters approach infinite time and the precipitation intensity that is associated with a long averaging time is so small as to be meaningless - yet low slope environments exist, are populated, and precipitation does generate runoff. © ASCE 2012.
