Middle States Geographer, 2007, 40:133-141 SPATIAL ANALYSIS OF HOUSEHOLD WATER SUPPLY AND DEMAND IN A DISTRIBUTED GEOGRAPHIC NETWORK IN THE TOWNS OF AMHERST AND

ABSTRACT: Spatial analysis of household water supply capacity and demand was conducted for the towns of Amherst and Clarence, New York. Spatial network models were constructed in Geography Information Systems (GIS) for simulations. Baseline data of household water consumption per person per day, population distribution, and transportation capacity of water main utility lines was collected for the model simulation. The results indicated that as the network extended eastward, southeast part of the Amherst and three of the four sub-regions in the Town of Clarence encountered the discrepancy of supply capacity in meeting the accumulated household water demand
