Abstract | A new approach to streamflow forecasting is described clearly but briefly in using the Fourier Series as a forecasting tool. A complete array of data is tabulated for the Logan River near Logan, Utah, using four (4) independent variables:(1) Daily and average monthly temperatures at valley stations(2) Daily and monthly precipitation at valley stations(3) Daily and monthly streamflow(4) April 1 snow survey data at 7 mountain stations in the Logan River drainage.Fourier Series coefficients are developed for these variables and applied to the 1956 field data. The resulting forecast for that year was only in error by 9% of the observed runoff.In discussion Mr. George R. Hamburg and Mr. H. Boyd Phillips pointed out the advantage of this seldom used forecast procedure for working with inflow to reservoirs. |
