Time of travel of selected Arkansas streams

Traveltime of water-soluble materials in streams is important for stream modeling, pollution studies, and estimating arrival time of contaminants to points downstream from spills.Between 1971 and 1981, timeof-travel and dispersion measurements were made in 15 streams in Arkansas.Most of the streams studied were at or near base flow.Graphs are presented for predicting traveltime of solutes in segments of the streams studied.The relationship of time of passage and peak unit concentration to traveltime is presented for two of the streams.Examples of use and application of the data are given.
