|Topic||Sediment: Median Particle Sizes (D50) for Corte Madera Creek 1999|
Caption: The Chart Table stetson_d50.xls.db shows bed surface particle size statistics for Corte Madera Creek tributaries in 1999. Data were collected by Stetson Engineers, Inc. A total of 21 pebble counts were collected throughout the watershed. See full report in KRIS bibliography. D50 is the median surface particle size, and D84 refers to the particle size with 84% cumulative particle distribution finer than. Mannings_n was computed from Limerinos equation, 1/sqrt (f) = 1.16 + 2.0 log10(R/D84). Mannings n = 0.0926 R**(1/6)/(1/sqrt(f)) where R is the hydraulic radius, assumed to be 1 foot. SLOPE was determined from step-backwater calculations using the USACE HEC-2 program.
