Abstract | The method described and a sample forecast for the Feather River, California is presented. The forecast formula or graphs are based on data for the April-July spring runoff period, during which the majority of snowmelt runoff occurs. The general parameters used include: the measured water content of the snowpack at high elevations, the carryover from previous years in the form of ground water, and late season precipitation. A 'percentage of normal' index (the normal based on a 50-year period) is used to convert raw data into a form readily adaptable for use in the multiple graphical relationship, permitting rapid calculation for an approximate forecast. Data on the normal precipitation and snowpack expectancy are graphed, and forecast diagram and forecast computation form for the Feather River are included. |
