The water-loss time series are formulated for the studied watersheds in the Ohio River Basin through the use of the law of water balance to the system inputs and corresponding outputs. Stochastic processes, including the five-step procedures, are applied to test the long-term water-loss time series. The best-fit models are used to forecast probable water losses which consist of infiltration and evaporation in the region. The results are within the upper and lower bounds of their expectations based on five percent significance level.
