Estimates of the time of travel of flow in natural streams are important to the hydrograph routine necessary for the planning and operation of flood control systems and to the routing of pollution movement needed for water management programs. Such estimates are particularly important when reacting to accidental spills that can contaminate downstream water supplies. This study develops, through multiple regression analysis of data on Georgia streams, prediction equations more accurate than current office approximations and less costly than tracer or other field studies. From the limited data available, it appears the equation for average velocity tends to underestimate travel times at high flows and over-estimate travel times at low flows. Only data for the north central and northwestern portions of Georgia were available for comparison. (Modified author abstract)
