Data: Node Number, NumElev 

 Sec E.2: Distance and Elevation pairs 



Data: (NumElev pairs of values) 

 Set E.3: Manning's Coefficient of Friction 



Data: (NumElev values) 

 EXTER.DAT 



115. This file contains time-dependent boundary data for each external 

 boundary node, tabulated as a function of time. Time-dependent data consist 

 of values of velocity or water surface elevation at external boundaries. If 

 wind effects are to be Included In the computations, the values of wind speed 

 and direction as a function of time are provided here. Details of the data 

 requirement are described as follows. 



116. Group F . Time -dependent data 



Set F.l: Index (a counter), Time (hour), values of elevation, dis- 

 charge, or velocity at external boundary nodes, values of wind 

 speed and direction when IWind has been assigned a value of 1 



Data: (list of values) 



PARAM . DAT 



117. This file specifies nodes and parameters for output files that 

 will be used by auxiliary programs. The auxiliary programs produce graphs and 

 tables for comparing computed outputs to field data, for displays, and for 

 other purposes. Similar to the START.DAT file, the PARAM.DAT file also 

 classifies data into groups of data sets, each data set consisting of a title 

 line identifying the data set, followed by one or more lines of data. 



118. Group G . Velocity output is given in this group. The number of 

 Group-G data sets equals the number of nodes (cross-sections) at which output 

 is desired. 



Set G.l: Number of velocity measurements (gages) with field data 



Data: NumVelG (one value) 



If NumVelG is greater than zero continue to G.3 



Set G.l: Number of nodes at which output of computed velocity is 

 required 



Data: VoutN (one value) 



Set G.3: Number of field stations at the velocity gage 



Data: NumVelGSt (one value) 



If NumVelG is zero, continue to G.5
