 WETP Data Format 



An example describing the WETP format is given in Appendix B. Much of the 

 form.it is self-explanatory. Carefully examine this example and the 

 explanatory notations before attempting to code your data on the coding 

 sheets. 



The five cross-sections in the example were located in riffles. The stage 

 height at zero flow (zf) was therefore set to the lowest elevation in the 

 cross-sectional profile for each. 



All elevations in the example were established relative to a single bench 

 mark, which was assigned an elevation of 100.00 ft for illustration only. A 

 bench mark elevation of 10.00 ft would be more appropriate and should be used 

 whenever possible. 



Enter the WETP data on the coding sheets in the following manner: 



1. Flows of interest (up to 100 flows are accepted by the program) 



Integers in cfs or with decimal points (not to exceed six 

 characters, including decimal point, if used) 



2. Cross-sectional profile data (up to 150 sets of measurements are 

 accepted) 



Distances from headstake - nearest 0.1 ft 

 Channel elevations - nearest 0.01 ft 



3. Stage-discharge data (2 to 10 sets of measurements are accepted) 



Stages (water surface elevations) - nearest 0.01 ft 

 Discharges (flows) - nearest 0.1 cfs 



4. Stage height at zero flow (zf) data (1 for each cross-section if desired) 



zf - nearest 0.01 ft 



If the cross-sectional profile, stage-discharge and zf data are entered in the 

 above manner, decimal points are not needed. However, decimal points can be 

 used if desired. 



Selecting Flows of Interest 



You will be extrapolating data for flows of interest that are less than the 

 lowest measured calibration flow for a particular cross-section. The
