 SECTION .DAT 



113. This input file contains detailed information on cross-section 

 geometry and boundary resistance. The cross -section geometry is defined by 

 data points identifying the channel boundary, and each data point is described 

 by pairs of values of distance and elevation. The boundary resistance is 

 defined by the value of the coefficient of friction at each data point. The 

 input data format is described in the following. 



114. Group E . Cross -section parameters (Note: The total number of 



Group E data values is equal to the number of nodes, N.) 



Set E.l: Node number. Number of elevation points at the cross section; 

 optional comments
