Rethinking Swale and Filter Strip Design
About the workshop:
Swales and filter strips are an important, but often overlooked, part of stormwater management and Low Impact Development. Being simple to construct, however, does not translate into minimal benefits. Swales "out-punch their weight" with respect to removal of certain pollutants. Recent research has led to new design guidance for swales that allows engineers and other designers to customize swale design to specific water quality goals, while still conveying needed flows. By making relatively simple adjustments to swale cross-section, length and grass height, swales can be very effective. This workshop will review the most innovative designs for swales. Design for urban areas will be emphasized.
Additionally, a new swale concept, the regenerative stormwater conveyance (RSC), which is a step pool conveyance system incorporating specially-designed media focused on nutrient removal, will be discussed. Recent research on these systems has shown potential hydrologic and water quality improvements.
As part of this workshop, attendees will need to bring laptops, as a simple swale design model (SwaleMod) will be distributed and demonstrated. You can also download SwaleMod by clicking this link.
The training will be from 9:00am to 5:00pm (registration at 8:30am). Download an Agenda by clicking here.
