Urban Storm-Drainage Systems Planning:Multilevel Approach to Urban Water Resources System Analysis--Application to Medium Size Communities.

摘要

The relationship between urban growth and the storm drainage problem is analyzed. A multilevel coordinated approach is used in a simulation-based optimization scheme that determines,at the planning level of details,the storm water system best suited for a given trend of urban growth. Similar models dealing with water supply and sanitary sewer problems would allow for a global analysis of relationships between urban growth and water resources. The simulation phase of the storm drainage planning model is provided by the module LANDSTORM,which is a combination of (1) the land use forecasting model LANDUSE (presented in Purdue University Water Resources Research Center Technical Report No. 100), (2) a modified version of the urban hydrologic model STORM developed by the U.S. Corps of Engineers and (3) their interface. An urban agglomeration is understood to be partitioned in several drainage basins. For each urban growth scenario of LANDUSE, STORM produces a corresponding performance of the local basin storm drainage system. The requirements of the subbasins composing the urban agglomeration are then 'coordinated'in the model URBDRAIN to produce a globally optimal storm water system for a given urban growth pattern.
