Temperature and turbulance effects on the parameter [delta] in the stochastic model for BOD and DO in streams

Abstract

The problem of stream pollution is of ever increasing concern today. It is a well known fact that use of the natural waterways of this country is rapidly becoming constrained due to the disposal of ever increasing quantities of man's wastes. If the recreational and aesthetic values of these natural resources are to be maintained, the dynamics of stream degradability and recovery must be accurately outlined and followed. In order to set stream standards it is necessary to understand the factors which affect the state of pollution. The prediction of stream conditions, given a set of parameters and pollutional loads, is also necessary in setting limits on these loads. Once the effect of a pollution source upon the properties of a stream is understood, knowledgeable action may be taken to preserve the overall value of the reach.
