Urbanisation has altered streamflow and severely degraded our natural aquatic ecosystems. It is vital that we look beyond studies of water quality and hydrogeomorphology and into natural baseflow regimes and whether restoration is possible to within the ecological limits. This review paper examines empirical studies of water sensitive urban design (WSUD) projects which report improvements to baseflow. It is apparent that baseflow is critical to stream health; however, it is inconclusive that current WSUD practices can systematically restore baseflow to within the natural ecological limits. Fortunately, a solution could exist by increasing infiltration within allotments and by expanding WSUD objectives.
