An Improved Temperature Prediction Model for Small Streams.

摘要

A model for predicting the maximum change in temperature from completely exposing a reach of stream to solar radiation was developed during earlier research. This model,which assumes that net solar radiation is the sole source of energy to the stream,worked well on most streams. In a few cases it worked very poorly. These streams contained either a large proportion of pools or bed rock in the stream bottom. Reducing the estimates of stream surface area and net heat load according to pool configuration and bed condition provided good estimates of temperature change using the original model. (Author)
