Show 6155 4153 the remainder of the year is less than 2000 second- feet. By The Special Master: Q And that is given in tabular form? A That is given in tabular form. Q In the other exhibit that you have been testifying to? A Those records are based on the periods, as shown on this particular graph ( indicating). Having determined the percentage of time and the number of days the flow was above or below certain amounts, and knowing the relation between the mean depths and the maximum and mean velocities for certain flows, it is possible to work up plates 7, 8, and 9. Plate No. 7 shows, for each of the gaging stations, the number of days in the year when the maximum velocity in the thread of the stream would be above or below certain veloci-ties in miles per hour. Taking, for example, the San Juan River at Bluff, which station for the greater portion of the year has the highest velocities. Take a velocity of four miles an hour, for ex-ample, It shows that the velocities in the thread of the |
