| Popis: | Hydrologists use double-mass analysis to verify the consistency of a precipitation or streamflow record. Precipitation of a station is plotted against the combined precipitation of the surrounding stations. The consistency of the record is verified if a single straight line fitted through the points is reasonable. The analysis is done on the computer by fitting a straight line and a fourth-degree polynomial through the points and comparing the two sums of squares of deviations of the points from the fitted curves. If a record is found to be inconsistent, it is adjusted by bringing the deviated points along a desired single straight line. The method should be of value to the hydrologists having access to computers. |
