Assessing Planning Approaches By Watershed Streamflow Modeling:Case Study Of The Woodlands, Texas, Bo Yang, Ming-Han Li

The Woodlands, Texas, is well known as a town created following Ian McHarg’s ecological planning approach that uses soil permeability to coordinate development densities and land use. Very few studies have quantitatively measured the effect of this planning approach on stormwater management. In this study, watershed stream flow modeling was conducted to assess five hypothetical land use scenarios. These scenarios were compared with The Woodlands’ 2005 condition using the Automated Geospatial Watershed Assessment (AGWA) tool that simulates watershed long-term stream flow and peak discharges during single storms. The objectives are to: (1) assess The Woodlands development conditions during 1974–2005 on …
