Hydrology of a vegetable raingarden and implications for vegetable growth

Abstract

Raingardens are systems engineered to both filter pollutants from urban runoff and regulate runoff rates, with the potential to reduce urban stormwater impacts on waterways. Raingardens also have considerable value as rainwater harvesting (i.e. water-saving) devices, and as ?green features? in urban landscapes. As such, the construction of raingardens and other biofiltration (or bioretention) systems has been actively promoted in several of the world's cities, including Melbourne. In late 2008, Melbourne Water introduced a community-focused ?10,000 Raingardens? initiative, which primarily encourages homeowners to actively manage urban stormwater through the building of raingardens and other ..
