<br />1. Increased bank erosion <br />2. Increase sedimentation <br />3. Land loss <br />4. Fish habitat loss <br />5. Loss of ripariatt and floodplain function (due to abandonn!evtt of [hc floodFdain) <br />6. Head-cuts which have altered the river profile outside of permit areas <br />7. Lowering of the water table and drying-up stream adjacent lands <br />8. Increased width'depth ratio which: <br />a. Decreases flood capacity <br />b. Increases stress ir, the tear-bank-region. adding to accelerated ban;: ~>rosion <br />c. Decreases over-winter and late summer/fall fish tsbitat and in-streari cover <br />d. Increases temperature extremes (winter and avnnter) <br />e. Increases channel slope <br />f. C?ecresses sinuosity, and meander width ratio (belt width'bankfull width) <br />g.
