This analysis will include a literature review to locate maps, photos, and other data needed to understand changes in the physical process along the San Joaquin River.

The number of plan and profile drawings generated will be determined based on the availability of data and the program manager's discretion. A cross sections analysis will be performed to determine the location of the current river channel, the 1.5, 25, 50 and 100 year flood plains, meander belt widths, cross-sectional area, valley slope, river channel slope, sinuosity, bank full flows, depth-to-width ratios, coefficient of friction, and channel capacity. The pr oject is located in Fresno, Madera and Merced counties and encompasses portions of the San Joaquin River watershed.
