If there is no RT record in the data set and riprap is required, the
following message appears:
DETERMINE RIPRAP SIZE FOR A GIVEN WATER DISCHARGE

(This message was produced by adding only an RR record to Test 2A. With no
RT record SAM had no idea where to put the riprap.)
Blench Regime Equations
Stable channel dimensions may be calculated using the Blench (1970) regime
equations. These regime equations are also shown in ASCE Manual 54 (ASCE
1975). The equations were intended for design of canals with sand beds. The
basic three channel dimensions, width, depth and slope, are calculated as a
function of bed-material grain size, channel-forming discharge, bed-material
sediment concentration, and bank composition.
