PLATTE RIVER RESOURCE LINKAGES <br />SEDIMENT-VEGETATION MODEL <br />January 2000 <br />LN-'TRODUCTION <br />The river channel width, depth, and vegetation composition can change over time. This change <br />is a function of river flow patterns, sediment supply, and vegetation growth. There is a need to <br />be able to predict how the channel will change over time in response to various management <br />actions. <br />NiODEL OBJECTIVE <br />The model objective is to numerically simulate the channel evolution of the central Platte River <br />over time while considering the interrelationship of the physical and vegetative processes and to <br />provide results that characterize the resources of interest. <br />MODEL PROCESS AND RESOURCE LINKAGES <br />River flow <br />• depth <br />• width <br />• velocity <br />Sediment transport <br />• erosion <br />• deposition <br />• grain size <br />Vegetation parameters <br />• indicator species <br />• growth rates <br />• removal criteria (scour, drowning, drought) <br />Habitat chazacteristics <br />• sandhill and whooping cranes <br />• least terns and piping plovers <br />• forage fish <br />• wet meadows <br />1
