Show 940 Q . ( "Mr Mr ) . . ( Hichardson Richardson ) , in making the extainination , ( of" of ) a river for the purpose of ( determining deterinining ) its usefulness , , . say , first , for navigation , what elements do you ( take- take ) into ( consideration consideratioa ) ? ( R . 3702 . ) Tlie WITNESS . Well , you take into consideration the question of fall of the river , the probable velocity during high water , and the depth of channel and , stability of the channel , the ( tortuousncss tortuousness ) of it . . ( R . . 3703 . ) The obstructions that there might be in navigation , in the way of boulders , rocks , tree stumps . , . . ( R . . 3703 . ) And the stream flow , particularly if the river is required to be moved by a ( slack-water slackwater ) dain . And the character of the bed ( itself-whether itselfwhether ) or not there was foundation suitable for the construction of locks and movable dams would be a very important element in it . ( R . 3703 . ) The fall of the Green River for about 30 ( miles iniles ) below Greenriver , Utah , is about 3 feet per mile ; , - and about a foot per mile for the rest of it . ( R . 3705 . ) The Green and Colorado Rivers are very tortuous , , or crooked , for a great number of curves of short radius endanger navigation , especially when the ( cur- cur ) rent has considerable velocity , it having a tendency to throw boats against a bar , a cliff , or a rock . . ( R . . 3706 . ) . ! The fluctuations in stream flow also affect the question of navigation very much . . Dependability of flow is what affects it . ( R . 3707-3708 . ) The conditions he found in that respect on the times that he was personally there he saw the Green River a number of times , extending over a number of months , possibly a year or ( more-a morea ) year or more . . . |
