<br />low flow channel and part of the high flow would be submerged. During iun~ff the high flow <br />channel would create a larger, more usable hydraulic feature (a hydraulic jump or wave train), <br />and at extreme flood the river will overflow the shoulders of the s1rUcture~ The downstream side <br />of these shoulders are stepped to provide seating during normal flows and to prevent the <br />formation of dangerous hydraulics during extreme flooding.

The low flow rate for which the Boating Parks were d~signed was based on b8sic <br />hydraulic formulas coupled with a working knowledge of this segment of the Arkansas River and <br />its characteristics.

Design of the structures in the Boating <br />Parks were based on basic hydra~c formulas coupled with a working knowledge of this <br />segment of the Arkansas River and its characteristics. At high flow rates, the wavef9rms; <br />hydraulics, eddies, and holes become more powerful and are conducive to play-boating, 'slalom <br />boating, and squirt boating. The structlU"es that will create these features are hy~u1ica1ly and <br />stru~ly sound, with anchors into the bed and banks of the river made of large stone and <br />concrete and are designe~ tQ withstand the rig~rs of high and flood flows. <br /> <br />-11- <br /> <br />
