Show 6133 Hoyt- D 4135 water rises. Is not that about what it is? A Yes, sir, that is what it 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 represent 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 occur and fill of the stream is indicated also on the curve ( indicating). For instance, be-tween measurements 152 ad 162, both are made at approximately the same gage height 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 taken at the same gage height, the same stage of water -- the |
