Calibration - a correlation between OBS readings and suspended-sediment concentration needs <br />to be defined. Suspended -sediment concentrations are obtained for various streamflows along <br />with an OBS value. Suspended-sediment concentration is obtained using the equal width <br />methods as defined in Edwards and Glysson (1999, p.48). <br />Sensor maintenance - sensor must be cleaned once a month to prevent and reduce biological <br />fouling. Readings shall be collected before and after cleaning to establish changes from fouling <br />Data Analysis <br />Data from the topographic survey will be exported from the surveying software (Trimble Survey <br />Office) and summarized as the distance from the bank and the elevation at every transect. <br />Graphs can be made using a plotting software package (Microsoft Excel) of the distance versus <br />elevation to reveal the outline of the bottom of each cross section. From the bed sediment <br />sampling, each transect will have 15 samples analyzed and lab statistics will be returned for <br />each. Statistic's include d16, dso, and d84, Information gathered from the stream gaging stations <br />will result in discharge data that can be summarized to the daily measures. <br />Model-based analyses can be conducted to quantify sediment movement and channel <br />modifications at each of the three reaches. <br />Research Budget Summary For the First Year Activities <br />(All figures in gross dollars) <br />Data Collection / Analysis <br />1.
