Improvement of flood-frequency estimates for selected small watersheds in eastern Kansas using a rainfall-runoff model
R.W. Clement
1983, Water-Resources Investigations Report 83-4110
The U.S. Geological Survey rainfall-runoff model was used to estimate model parameters for 13 small watersheds in eastern Kansas with drainage areas of less than 11 square miles. Model parameters and rainfall data from three long-term rainfall stations were used in the model to synthesize long-term records of simulated annual...
