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 …

Calibration Of Land Use Change Drivers In Support Of Dynamic Urban Growth Modeling, Woonsup Choi, Zhanli Sun
Geography Faculty Articles
The Land use Evolution and impact Assessment Model (LEAM) is a cellular urban dynamics model designed to simulate changing landscapes over space and time. One of the challenging problems in the LEAM model is calibrating the model results, and this study presents a step to calibration. The probability of land use change in each cell is determined by various factors including a cell’s proximity to development attractors, which are physical features that promote residential and commercial developments. This study presents a way to calculate a cell’s proximity to development attractors and converting the proximity to relative probability to help with …
