In the case of vertical bank, <br />use 0.05 for BSP. This value is used for all cro- <br />ss sections unless otherwise specified in Field 8 <br />of XF record for a section. <br /> <br />Downstream slope is allowed to vary during flow. <br />Downstream slope is fixed at 511 given in Field 1. <br /> <br />Water temperature is 15oC. <br />Water temperature in degrees Celsius <br /> <br />Manning'S n defined in Field 7 of the Gl record <br />or Field 4 of the XF record are used. <br />Brownlie's formula for alluvial bed roughness is <br />28 <br />
