The research was to prepare a model of the lower reaches of the Kansas River drainage basin. This model was to be used for operational and planning activities within the basin. During the course of the investigation, it became apparent that the biological, the chemical, and the time of flow data on the model region was insufficient to establish many of the parameters required to accurately describe the behavior of the drainage system. The report describes the chemical analysis of twenty-two samples each week for a period of thirteen weeks and for the mathematical correlation of the data.
