Some creeks have very large and wide stream beds which will result in <br />' essentially creating channel storage areas. In addition to this, is the presence of numerous dams <br /> in pulleys to control run-off conditions which act as retention ponds. <br />' <br /> MUSHINGUM ROUTING METHOD <br /> <br /> The size of the sub-basins in the upland watershed require using the channel process in an effort to <br />' maintain a reasonable level of design accuracy. <br />' In this particular watershed, the entire area of some 280 square miles has been divided into 75 sub- <br />basins. As the length of the stream reach and the size of each sub-basin increases, the storage in <br />' the stream reaches increases. The channel process becomes very important because this process <br />accounts for the effects of channel storage. <br />The term Channel Routing is the term applied to the methods of accounting for the effects of <br />' channel storage on the run-off hydrograph as the hydrograph moves through the channel reach. <br />Of the various routing methods available, the Muskingum Routing Method was selected for this <br />' study. The Muskingum Method has been widely used for decades and because no data are available <br />that have been derived from the analysis ofine2s~ued hydrographs, as is thr case for tl~e Tallahas~: e <br />Watershed, the Muskingum Method is most applicable to our study. <br /> <br /> <br />1 <br />PAGE 9 <br /> <br />
