The first part is reported of a program of analysis of hydrologic time series and stochastic models for the synthetic generation of rainfall and runoff sequences principally in Indiana. The study was conducted on 12 watersheds varying in area from 100 to 3750 square miles. All the watersheds had 20 years or more of continuous records of rainfall, temperature and runoff. The probability distributions of the annual discharge, monthly flows, and the normalized square root of the monthly precipitation are given. A spectral analysis of the monthly raw data and transformed data revealed a strong annual component which was removed by normalization. Logarithmic and square root transformations of the monthly runoffs and precipitations were performed for further analysis. The hydrologic process of monthly rainfall-evaporation-runoff was simulated by a linear dynamic stochastic model with multiple inputs.
