Show 134 of silt carried past the gaging station on Colorado River near Cisco in suspension during the ( itwe-inonth itweinonth nive-i-nonth niveinonth ) period November , 1914 , to July , , 1915 , , was 9,110,000 tons . . This is exclusive of sediment carried by Court House Wash , Mill Creek , , and other washes and includes no , bed load . C . . S . . Howard ( Abs .

Geological Survey for the purpose of ( deter- deter ) the actual of sediment mining quantities , are as ( ac- ac ) curate as any that can be made . Although to date the laws governing the habits of ( silt-laden siltladen ) streams have not been well established , their characteristics are fairly well known . . It has been established quite definitely that the higher the velocities in the stream . the more sediment will be carried in the channel , and vice versa , and also that the amount of sediment transported has a relation to the size and character of the sediment and the |
