A One-Dimensional Model for Prediction of Excess Temperatures in a Fjord
- 92 Downloads
A one-dimensional mathematical model for direct calculation of the longitudinal mixing parameters and distribution of excess temperatures is presented. The model has been applied for prediction of excess temperatures due to an increase in cooling water discharge in a Danish estuary, Kalundborg Fjord. The model calibration is direct in the sense that explicit calculations of the longitudinal mixing parameters are obtained on the basis of observed longitudinal excess temperature profiles caused by the present use of cooling water. The effect of discharging the cooling water of the plant extension closer to the mouth of the estuary is investigated. The influence of occasional density circulations is discussed.
