<br />J024:99 <br /> <br />provide deep passage during typical low flows. During the mid-range flows the low flow <br />channel and part of the high flow would be submerged. During high flows the high flow <br />channel would create larger usable hydraulic features (a hydraulic jump or wave train for the <br />U-structure and a wave train for the ODD), and at extreme flood the river will overflow the <br />shoulders of the structure. The downstream side of these shoulders, as shown in Figure 6, aJ:e <br />stepped to provide seating during normal flows and to prevent the formation of dangerous <br />hydraulics during extreme flooding. <br /> <br />Overilo'i.V Chafuiel. <br /> <br /> <br />Figure 8. The downstream view of the V-structure shows how it is designed to accommodate <br />varying flow levels. <br /> <br />Low Flow <br /> <br />The Whitewater Park will have a low flow rate of 250 cfs. Water at this flow rate will <br />be controlled and diverted throughout the Whitewater Park and will not be wasted. The <br />low flow rate for which the Whi~ewater Park was designed (250 cfs) was based on basic <br />hydraulic formulas coupled with a working knowledge of this segment of the Gunnison <br />River and its characteristics. The structures are hydraulically and structurally sound, <br />with anchors into the bed and banks of the river. <br /> <br />The structures and their elevation/configuration were designed to provide depth for <br />boating during low flows, even when the wbitewater wave features are not present. <br /> <br />15 <br />
