The objective of this study is to determine the effects of cooling water discharge from asmall scale power plant by using a 1-D numerical heat and solute transport model WASP 7. The goal ofthe modeling is to determine the effects of the discharge by estimating the difference in stream watertemperature before and after release. The cooling water was released to an ephemeral stream that flowsthrough an industrial zone, receives surrounding storm water and interacts in some parts with the underly-ing aquifer. The release rate was unsteady during the monitoring period of the study. Average temperatureof the cooling water was 23.6 °C with a maximum of 35°C.Field work was conducted to collect data that was necessary for the modeling stage. Flow rates weremeasured with an acoustic Doppler velocimeter at six transects of the stream. Water temperature, dis-solved oxygen concentration and electrical conductivity were determined by collecting water samples ateleven monitoring points. Modeling results indicate that the warm water release is somewhat effective inthe dry period up to 600 m downstream of the release location. The estimated stream water temperaturedoes not exceed 22 °C, thereby complying with regulations.Keywords: Water quality modeling, Surface water, WASP, Water temperature, Cooling water, Dischargerate measurement, ADV
