WebFor example, a structure can be designed to perform well within some range of flows, such as flows that occur between 20 and 80% of the time (or some other selected interval). … Websteps can be done quickly and flow duration curves can be created as we described above. However, some flow duration analyses are still made by grouping data into size classes. … WebDec 24, 2015 · A total of 115 regression equations were developed in this study to calculate flow-duration curve and low-flow frequency statistics for ungaged locations in the study area. In addition, data from 25 pairs of streamgages were used to develop drainage-area ratio equations that can be used to estimate streamflow statistics at ungaged locations on ... map of iran and syria
