Quantitative analysis of streamflow: the importance of precipitation and geomorphic factors in determining yields from small watersheds. Research technical completion report, project A-062-IDA Item Info

Stream flow data from 12 drainage basins located in the rocky mountains in Northern Idaho that covered 12.43 square miles were statistically analyzed and related to factors such as basin length, basin area, square miles, relief ratio, and precipitation levels. The resulting linear regression (R-square value of .87) indicates that geomorphic factors as well as precipitation play a dominant role in explaining variations in streamflow. The regression model was then applied to the much larger Meadow Creek watershed (approximately 243 square miles). The Thiessen method, which assumes linear variation of precipitation between stations and assigns each segment of area to the nearest station, was used to determine precipitation values for the Meadow Creek basin. The regression model, on a number of occasions produced a prediction that was similar to actual yield from the larger basin.
