Abstract
Pavements, rooftops and compacted soils inhibit rainfall infiltration across our cities and drains built to prevent flooding can further reduce water availability to urban ecosystems. These hydrological changes diminish the provision of ecosystem service benefits to local populations and negatively impact downstream communities and environments. Stormwater engineering can help restore infiltration, but little use has been made of infiltration systems in expansive clay soil (often referred to as reactive clay), due to the potential for problematic shrinking and swelling soil movements in response to changes in soil moisture. In an experiment in South Australia, ground movement and moisture va..
