Abstract

A standard procedure for determining the distribution and variation of the heat assimilative capacity of a river has been developed. Hydraulic geometry equations for the Sangamon River Basin are used to provide the necessary hydraulic information. This study indicates that the total heat assimilative capacity of a river depends on the location of power plants, residual temperature, flow frequency, and seasonal variation of water temperature and wind speed. Water temperature data from 18 aging stations in the Sangamon River Basin and wind speed data from 5 weather stations in or near the basin are used to determine the surface transfer coefficient for excess heat along the Sangamon River. This coefficient can be approximated by four equations for different ranges of wind speed. An analysis of the cost-capacity relationships for 29 power plants indicates that the cost per kilowatt of power output decreases with increasing power plant capacity.
