Design criteria and standar~s will be developed for the following <br />features: <br /> <br />a. Sizing criteria for hydfaulic features including pipelines, <br />pumping, plants, reservoir size, and outlet works. <br /> <br />b. Hydraulic losses for ca~als and pipelines will be assessed; <br />structural design critefia will be developed for the major <br />structures, including: <br /> <br />- Stability analysis of the proposed embankments <br />- Volume and peak discharge of inflow design floods <br />- Spillway design <br /> <br />Flood routing will use standard Corps of Engineers criteria. <br />Volume and peak discharge of design floods for the spillways <br />will be prepared. (New or enlarged diversion dams are not <br />included in this scope af work.) An evaluation of the flood <br />and erosion hazard of the facility will be prepared. <br /> <br />c. Vhere appropriate, sizing criteria for cross-canal drainage <br />culverts will be prepared, as necessary. The maximum, <br />minimum, and normal water surface elevations will be <br />identified for pumping facilities. The number and sizes of <br />pumping units in pump stations will be selected to provide <br />flexibility for varying water demands. <br /> <br />d. Preliminary designs of pump stations will be prepared to <br />proportion side and back wall clearance and submergence of <br />pump intakes to limit approach velocities to the pump's <br />acceptable limits. <br /> <br />7 <br />
