The amount and distribution of impervious surfaces are important input parameters of hydrological models, especially in highly urbanized basins. This study tests three different methods to input impervious surface area information to a semi-distributed hydrological model in order to examine their effects on storm flow. The three methods being evaluated include: (1) a constant value for impervious surfaces in the entire urban area, (2) constant values of imperviousness for commercial and residential land uses, respectively, and (3) different imperviousness for the residential land use in each subbasin. Storm flow of the Milwaukee River Basin in southeastern Wisconsin (USA) was modeled …
Subbasin Characteristics And Hydrological Response To Anticipated Urbanisation, Woonsup Choi
Subbasin Characteristics And Hydrological Response To Anticipated Urbanisation, Woonsup Choi
Geography Faculty Articles
This study investigated the relationship between the hydrological response of a river basin to anticipated urbanisation and its subbasin characteristics by applying a hydrological model (HSPF) with land use scenarios generated by an urban growth model (LEAM). The hydrological model was set up and run for the Kishwaukee River basin in northeastern Illinois, USA. The results show that the subbasin size and imperviousness were found to be more correlated to runoff changes than slope. However, no basin characteristics have significant relationships with percent changes in any hydrological variables due largely to the effects of upstream subbasins. When the effects of …
