Method of calculating the flow rate estimation regression function of mountain river basins , method of selecting the same function , and the annual average flow rate estimation method of mountain river basins

摘要

Is to provide a method of calculating the flow rate estimation regression function that can [ challenge ] revised river flow estimation method based on watershed ratio of the prior art, to accurately estimate efficiently the flow of mountain rivers flow unmeasured . Based on the topographic map of the resolution means a commercially available , to calculate the altitude zone by elevation and altitude zone another area of study river basin , were used to calculate basin correlation and elevation basin three-dimensional terrain correlation area as input data these , each Hakamizu-sho three-dimensional terrain correlation area was calculated as the measured value of the annual average flow rate of Hakamizu plant basin corresponding to the measured value of the average annual flow in the basin , calculated using the ( registered trademark ) and mathcad is a technical computing software water estimated flow from the altitude method of calculating the flow rate estimation regression function of mountain river basins that .
