Urban Growth in Water Resources Planning:Multilevel Approach to Urban Water Resources Systems Analysis-Application to Medium Size Communities.

摘要

The relationship between urban growth and water resources related problems is analyzed. The distinct aspects of a urban water resources system are supply,sewer disposal and storm drainage. A goal of the study was to identify the common elements in the causal relationships between urban growth and these different aspects of the urban water resources systems. The theory of hierarchical multilevel decomposition and coordination was used. Two-level hierarchies were developed where the separate modules for the water supply and sewer system on the one hand,and the storm-drainage system on the other,interact only through a common urban growth process. The urban growth process is simulated by means of the LANDUSE model, a modified version of the Walsh and Grava model. An example of application of the LANDUSE model is presented for the case of the City of West Lafayette,Indiana. (Portions of this document are not fully legible)
