dc.description.abstract | The objective of this research is to classify rivers based upon generic gage height-discharge rating curves so as to reduce the number of measurements required for rating curve development. The first step has been classification according to the uniqueness of the gage height-discharge relationship. The USGS National Water Information System database of 3.68 million pairs of gage height vs. discharge measurements at 61,240 gaging stations was imported into a Python-driven data manipulation script, resulting in 15,153 gaging stations after removal of incomplete and inconsistent data. At each gaging station, the linear relationship ZlnGH = mZlnQ = b was determined, where ZlnGH and ZlnQ are the Z-scores of the logarithms of gage height and discharge, respectively. Each linear relationship was converted into a normal distribution with mean and standard deviation equal to m and its standard error, respectively. Summation of the normal distributions showed a single peak at m = 0.991, where m = 1 indicates a unique gage height-discharge relationship. There are no gaging stations with m > 1, equivalent to no gaging stations with variation in discharge without variation in gage height. Over 30% of gaging stations had m < 0.9, indicating significant variation in gage height without variation in discharge. Based on 209 gaging stations in Utah, extreme independence of gage height from discharge (m < 0.6) can be avoiding by not locating gaging stations close to either the upstream or downstream confluence (within 10% of the reach), which precludes the effects of flood waves and reverse flow. | |
