    Permeable Catchments

    When precipitation falls on permeable catchments, a large portion of the water infiltrates into the ground. This water then makes its way to the water table and ultimately the groundwater. Since groundwater moves significantly slower that surface runoff or surface water, this will create a lag time between a rainfall event and water entering the river. It will also not allow for "flash flooding", as water will be delivered the the stream system slowly, instead of very rapidly, which is the case in urban ...

    Solution Summary

    This solution discusses the differences in the respond to rainfall events between rivers and streams on highly permeable and impermeable catchments and discusses how bank storage can modify the flooding response of rivers to storm events.
