Show 6133 575 Hoyt- D 4133 water rises. Is not that about what it is? A Yes, sir, that is what is shows. And it is the re-lation from which the discharge is computed. By Mr. Blackmar: Q That is, given the gage heights -- A The approximate flow can be determined from this curve ( indicating), the approximate fall. Q That is, the discharge, or can you also compute the velocities from it? A From that, as I will explain later, the velocities and depths. The second curve represents the approximate relation be-tween the stage and the cross- sectional area, as shown on the first plate, that is, the number of square feet in the cross-section of the river. The accur and fill of the stream is indicated also on the curve ( indicating). For instance, be-tween measurements 152 and 162, both are made at approximately the same gage heights of 17.8. The area in cross- section of the water when measurement No. 152 was taken was 8000 square feet. The area of the water when measurement No. 162 was |
