<br />Recommendations for Future Studies <br /> <br />Bed material samples should be collected to quantify the percentage <br />of fines within the bed material surface. <br /> <br />Results from the Water Surface Profile program increase in <br />reliability as the range and number of measured flows increase. <br />Discharges during the peak flow periods are especially needed to <br />help define forces exerted upon bed material. <br /> <br />The WSP program could be modified to compute the Beta movement <br />parameters for individual conveyance areas rather than for the <br />entire cross section. This would allow greater examination of the <br />forces across the stream channel as opposed to an average. <br /> <br />Changes in the water or sediment budgets caused by future projects, <br />especially on the Gunnison River or downstream tributaries, may <br />adversely affect channel stability or substrate, and should be <br />evaluated on a case by case basis. Changes in channel morphology <br />observed in recent years were caused by flows in excess of the <br />IOO-year event in concert with gravel pits, bridges and dikes <br />constructed adjacent to the river (as noted at the unstable Walter <br />Walker habitat site). Channel stability at individual habitat <br />sites selected for PHABSIM analysis should continue to be evaluated <br />since tributary inflow, artificial structures and/or geologic <br />controls may affect non-typical sites within the overall stream <br />reach. <br /> <br />11 <br />
