w <br />I`~ <br />The entire study reach, from the razorback spawning site to the downstream wetlands <br />is seven miles long. Several cross sections were surveyed in the intervening reach between the <br />spawning site and the wetlands to create a single hydrologic reach for water surface simulation <br />with the Corps of Engineers (COE) HEC-2 computer model. Water surface elevations were <br />predicted for all 23 cross sections in the study reach. <br />To supplement the river survey data., several wetlands cross sections were surveyed with <br />a total station. In addition, numerous topographic shots were surveyed at various locations in <br />the wetlands to determine possible flow paths and potential water surface elevations. This <br />topographic survey data was compiled and analyzed to determine the potential for inundating <br />the wetlands with river flows. The proposed hydrologic connection of the river and wetlands <br />would occur for a prescribed frequency of flows. <br />This report is organized into the following sections: a brief description the Green River <br />study reach; report on the data collection methods; presentation of the field data analyses and <br />results; summary and conclusions; and recommendations. The original cross section data and <br />discharge data, bed material size distribution results and photos of all the cross sections are <br />presented in accompanying Appendices. <br />2 <br />
