GVSF for ditching <br />and channel design. physical model tasting for approach channel and pump sump analysis. <br /> <br />GVSF or GVUSF analysis, physical model testing. movable boundary analysis on sediment-laden streams. <br /> <br />Simiar to stilling basin design, although model tests ollen not required. <br />GVSF usually. GVUSF for major confluences or tidal effects. <br /> <br />GVSF normally. GVUSFlMulti.D for very wide floodplains or alluvial fans. <br /> <br />GVSF normally. <br /> <br />Dikes - Movable boundary analysis (quantitative). multidimensional modeling. physical madel tests. <br /> <br />Cutoffs - GVSF or GVUSF. movable boundary analysis to establish the rate of erosion and channel shilling, <br />physical modefing. <br /> <br />Revebnenl . general design criteria from existing sources. GVSF, physical madeltasts. <br /> <br />Normally. GVSF to establish pool elevations. prafilas and depths. multidimensional modeling to estimate current <br />patterns. physical model testing, movable boundary analysis to establish downstream scour for stilling basin <br />design. <br /> <br />General design criteria from existing sources. possible multidimensional modeling/physical modeling for approach <br />and exit velocitias and refinements of lock design and filling/emptying systems. <br /> <br />System simulation for optimal operation. Multidimensional analysis for flow pattems. physical model tests. <br /> <br />3-5 <br />
