WINSLAMM - WINDETPOND
Robert Pitt - University of Alabama
SLAMM was originally developed to better understand the relationships between sources of urban runoff pollutants and runoff quality. It has been continually expanded since the late 1970s and now includes a wide variety of source area and outfall control practices (infiltration practices, wet detention ponds, porous pavement, street cleaning, catchbasin cleaning, and grass swales). WinSLAMM is strongly based on actual field observations, with minimal reliance on pure theoretical processes that have not been adequately documented or confirmed in the field. SLAMM is mostly used as a planning tool, to better understand sources of urban runoff pollutants and their control.
Detention ponds are probably the most common management practice for the control of stormwater. If properly designed, constructed, and maintained, they can be very effective in controlling a wide range of pollutants and peak runoff flow rates. There is probably more information concerning the design and performance of detention ponds in the literature than for any other stormwater control device. Wet detention ponds are also a very robust method for reducing stormwater pollutants. They typically show significant pollutant reductions as long as a few design-related attributes are met. The WinDETPOND stormwater detention pond model can be used to evaluate and design stormwater detention ponds for a wide range of conditions. WinDETPOND is based on the same modeling approach used in WinSLAMM, but provides more detail to enable more effective evaluations for many site conditions.
