Figure 6. The U-structure at Charlie's Hole in Steamhoat shown at 1850 cfs. <br /> <br />Depth of flow <br /> <br />The specific dimensions of the V-structure are tailored by the designer to create the <br />desired in stream features. One of the most important variables that is controlled is the depth. <br />The depth is described by the Weir Equation, which can be expressed as, <br /> <br />Q = Cbh1.5 <br /> <br />(1) <br /> <br />where C is an empirically determined constant, b .is the river width as defuled in the analysis <br />section and h is the height ofthe flow. The weir equation can be used todetennine the <br />approximate depth of the flow in the specific channels. Note that this Equation is an <br />approximation and does not represent an exact relationship. The actual depth at the top of the <br />structure canvary due to a number of variables such as upstream current velocity, roughness of <br />the riverbed or variances in the structures geometry. . <br /> <br />The City of Steamboat Springs Boating Park was designedto function at a variety of <br />levels. During high flows the structures were designed separately such that each structure has <br />unique characteristics at differing flow rates. The depth and width of the structures at high flows <br />is shown in Table 1: . <br /> <br />-11- <br />
