Draft Outline for Geomorphic Research Protocols <br />1. Flow and Vegetation Research and Management Protocol <br />• use LiDAR mapping and aerial photos from the Protocol for Aerial <br />Photography and airborne terrestrial LiDAR <br />• use hydrologic data from the Geomorphic Monitoring Protocol <br />A. Channel Conveyance Study (includes 1D modeling) - Choke Point studies and actions <br />(already begun, not completed) <br />B. Study of tributary flow inputs and general channel groundwater losses <br />C. Flow regime and wet meadow study? (includes 1D or 2D)- (use in-stream data from <br />the Yegetation Monitoring Protocol) <br />D. Analyze, design and assess the delivery of pulse flows (program water <br />management study) and test this experimental treatment (already begun, not <br />completed, use flow models and in-stream data from the Vegetation Monitoring <br />Protocol) <br />E. Analyze, design and assess split flows at major channel divides using the pulse flow <br />experimental treatment and 1D or 2D modeling <br />F. Analyze, design and assess vegetation removal by flow shear using the pulse flow <br />experimental treatment and 1D or 2D modeling-(already begun, not completed, use in-stream <br />data from the Vegetation Monitoring Protocol) <br />G. Analyze, design and assess the elevation of the vegetation green line and flow <br />regime/inundation effects, using the pulse flow experimental treatment and 1D or 2D modeling- <br />(use in-stream data from the Yegetation Monitoring Protocol) <br />H. Analyze, design and assess sand bar elevation change resulting from <br />the pulse flow experimental treatment and natural flow events (use 2D or 3D <br />model) <br />II. Sediment Research and Management Protocol <br />• use LiDAR mapping and aerial photos from the Protocol for Aerial Photography and <br />airborne terrestrial LiDAR <br />• use cross section and transect data from the Geomorphic Monitoring Protocol <br />• use sediment transport data from the Geomorphic Monitoring Protocol <br />A. Study to identify sediment sources in the central Platte River (already begun, not <br />completed) (aided by LiDAR mapping and modeling) <br />B. Study to determine the sediment budget in the central Platte River (already begun, not <br />completed) (aided by 1D modeling) <br />C. Study of phragmites impacts on sediment movement, channel plan form and shape <br />(aided by 1D or 2D modeling) - will use In-stream data from the Vegetation Monitoring Protocol <br />D. An investigation of alternatives to augmenting sand far eliminating the sediment <br />imbalance between the J2 and Kearney. <br />E. Analyze, design and assess the sand augmentation experimental treatment to remove <br />the sediment imbalance from the J2 return, and increase the channel width-to-depth ratio and <br />Page 2 of 3 DraftJuly 2, 2007
