    1. 1. Channel and Floodplain Alterations for River Restoration Melinda D. Daniels, PhD Fluvial Geomorphologist
    2. 2. River Restoration Should aim to re-establish normal rates and magnitudes of physical, chemical, and biological processes that create and sustain river and floodplain ecosystems Rivers are: Dynamic Self-sustaining Responsive to their watershed inputs Habitats are by nature dynamic in both space time and are controlled by physical stream processes
    3. 3. Fundamental River Proceses Natural River Driving Processes Fluvial Geomorphology Sediment Transport Bank Erosion Channel Meandering Wood Loading Flow Regime Altered River Restored River Restoration Solutions
    4. 4. Nielson et al., 1994 Saldi-Caromile et al., 2004

    12. 12. Plum Run, Brandywine
    13. 13. Restoration Strategies Restored River Target root causes of habitat and ecosystem change Restore Riparian Forests Focus on connecting existing high quality patches Decrease storm water and sediment runoff from urban and agricultural lands Add large wood Remove Dams and Stabilize Legacy Sediments
    14. 14. The Ten Commandments of River Restoration 1.Do No Harm 2.Direct channel manipulation should be a LAST resort 3.Hire someone who can properly assess the system 4.Look beyond the channel reach (upstream) to assess drivers of degradation 5.Manage inputs to the system (stormwater, sediment) 6.Allow the channel to self-adjust 7.Emulate natural systems 8.Use appropriate materials 9.DO NOT lock the channel in place 10.Expect and accept change
