bioswale

Wet swales can provide runoff filtering and treatment within the conveyance system and are a cross between a wetland and a swale.

Grass channels can provide a modest amount of runoff filtering and volume attenuation within the stormwater conveyance system resulting in the delivery of less runoff and pollutants than a traditional system of curb and gutter, storm drain inlets and pipes.

Most stormwater practices were originally developed in the Piedmont physiographic region and have not been adapted for much different conditions in the coastal plain.

Design considerations and issues in state stormwater guidance for stormwater in coastal plains webcast.

Delaware study finds that 60 percent of bioretention sites had a significant amount of mosquito breeding for most of the summer season.

From a stormwater perspective, terrain matters a lot more than state boundaries. However, the bulk of stormwater research has taken place in only one terrain.
