Show ( calculation talculation ) of two sets of 982 samples ( for -for for ) that day . R . ( 3S26-3S27 3S263S27 S826-3827 S8263827 ) . ) During his work he made ( some soine ) observations as to the process referred to as ( "scour scour ) and ( fill" fill ) and has charts which show graphically some of the changes , the charts being based on soundings made from the cable during the period ( he lie ) was there . This chart , Compl . Exh . 495 , is made up based on ( soundings -soundings soundings ) taken at nine different points on a ( cross- cross ) section of the river at the cable , this being the ( thirty- thirty ) foot point , and this being the ( 190-foot 190foot ) point . These surfaces represent the surface of the river referred to the gage height at that particular period . And he plotted these points , referred to given gage heights . For instance , on September 10 , he had a point , say , four feet above zero on the gage . But back on August 15 , that same point was only two feet above the zero of the gage between those two times , August 15 and September 10 , a fill of two feet at that point . Other points were similar . That indicates very nearly the width of the river at that [ particular ] point . This ( 30-foot 30foot ) point was usually about five or six feet from the edge of the right bank of the river , and this ( 190-foot 190foot ) point was about 10 to 15 feet ( from frorn ) the edge of the river . ( R . 3827- 3828 . ) The width of the river at that point would , ( there there- there ) fore , be about one hundred and ( sixty-five sixtyfive ) or one ( hun hun- hun ) dred and seventy feet . There is a narrow point , ( however bowever ) , considerably above the cable . |
