Subject: Distribution of ASCE Report, "Predicting Travel Time
and Dispersion in Rivers and Streams," by Harvey E. Jobson
The WRD is often asked to predict travel time and attenuation of peak
concentrations that may result from a contaminant spill. The attached

data and develops a simplified prediction procedure to address these
types of problems. It also illustrates how time-of-travel data can be
