Ref. <br />R3-1 Minimum Data Needs being <br />Hypotheses <br />No. ProtocoUActivity Description, Responsible Party, and Schedule addressed 13 year Budget Addressed <br /> Comprehensive geomorphic Description: This investigation will provide a qualitative and quantitative <br /> assessment from Lexington to geomorphic assessment of the Platte River. Existing data will be compiled <br /> Chapman, Nebraska and a substaintial amount of new data on the current and historical form of the <br /> river will be collected, focusing primarily on the reach from Lexington to <br /> Chapman with possible extensions upstream and downstream. Development <br /> of a comprehensive assessment of the river's form and processes controlling <br /> the form are necessary precursors to implementation of any treatments <br /> intended to modify the river's form. The comprehensive geomorphologic <br /> assessment will also provide a forum for interaction among the various <br /> investigation components to allow development of an appropriate <br /> interpretation of the results of the various investigations regarding meeting of <br /> habitat objectives from a sediment, vegetation, and geomorphic perspective. <br /> Further description provided in the Parsons/EIS Team report. Responsible <br /> Party: Program. Schedule: Research will begin once necessary lands are <br />5 available and s ecific rotocols are written. $2,645,115 <br /> Investigation of river Description: This study will test the performance and effects of pulse flows, <br /> restoration activities measures to remove vegetated islands, and measures to create sand bars. <br /> The pulse flow would be tested in three phases: The first, initial phase would <br /> be to gather information on discharge wave travel times and wave attenuation <br /> and on river stage at locations where there is concern about potential flooding <br /> problems. Selected vegetated river islands would be cleared and lowered <br /> from each of four study reaches prior to the second pulse flow test. The <br /> second and third pulse flow tests would be conducted to study the removal of <br /> new vegetation on the river bed and sandbars, the building of new sandbars <br /> (with and without woody debris), and other sediment transport processes. <br /> Further description provided in the Parsons/EIS Team report. Responsible <br /> Party: Program. Schedule: Research will begin once necessary lands are <br /> available and specific protocols are written. <br />6 <br />$1,190,760 <br /> Aerial Photo ra h and GIS <br /> Protocol for Aerial Description: Provide aerial photographs at regular intervals throughout the 1) Wet meadow quantity, distribution, <br /> Photography in the Central Program for analysis in other protocols. Black and white photographs will be and quality. 2) Wet meadow proximity <br /> Platte Valley taken in even years and cover the 1 mile area on either side of the centerline to roosting habitat, isolation. 3) <br /> of the river. CIR photographs will be taken in odd years and cover the 3.5 mile Channel width, vegetation, and <br /> area on either side of the centerline of the river. Responsible Party: sandbar quantity, vegetation, sand <br /> Program. Schedule: Aerial photograpy began in 2000 and will continue area, and distribution, 4) CIR, B/W, <br /> annually as described in the Protocol Ortho-CIR for quantity, distribution, <br /> sand area, and proximity to feeding <br /> habitat for sandpits <br />7 <br />$280,000
