When retrieving soil moisture from microwave radiometry, the effect of this factor can be parametrized by multiplying soil reflectivity by the negative exponential of h cos theta. This factor can be calculated using the Limerinos equation to solve for a coefficient sometimes co-named for Gauckler. This factor can be estimated for soil using a pin board or an ultrasonic rangefinder. For streams with a high value of this factor, metrics of this factor include D84 and Z-sigma. (-5[1])Manning’s “n” coefficient (15[1])is related to sinuosity (15[1])and this factor. A (*) Moody chart illustrates the relation between this quantity, Reynolds number, and the Darcy-Weisbach (10[1])friction factor. (-5[1])Root mean square height is a common metric of this quantity. For 10 points, name this quantity that describes how much a surface deviates (10[1])from a smooth plane. (10[1])■END■ (10[6]0[1])
