Show ( patience parience ) since 1909 has ( 27 '217 ) been ( relative elaave ) . 1a ( Tivers- Tivers ) ( Experience Dxperience ) has been on ( principal prilicipal ) rivers of ( the tlAe ) United States . ( R . 136-137-138 . ) ( An 'An An ) entire river basin has to be studied as a whole in practically all hydraulic problems . It is a ( recog recog- recog ) ( nized uized ) principle of hydraulic engineering that in the study of a particular river the entire basin must be , considered . Study is made of the stream flow , the ( amount aniouut ) of silt , sediment , driftwood , and other ( con- con ) ( ditions d7itions ) dependent upon the tributary ; and , in ( fact fadt ) , the entire basin . ( 13 . 138 . ) In all the Geological Survey work basins as a whole are studied to arrive ( at -it it ) the answev to any one particular point . At the direction of the Secretary of the Interior , ( he lie ) ( made iiiade ) an examination of the Colorado River . from Moab , Utah , to its junction with the Green River ; of the ( Green Orreen ) River from Greenriver Utah , , to its junction with the Colorado River . ( R . 139 . ) He filed a report of his investigation with ( Ms his ) ( supe supe- supe ) ¬ rior officers ( Compl . Exhibits 75 , 76 , 77 and 78 , R . 146 . ) ( His ITis ) report is in no sense a partisan ( report Teport ) . It is a technical report of conditions as he found them . ( R . 143 . ) He ( aiuived arrived ) at Greenriver Utah September 27 , , , ( 1928 -1928 ) , whereat the government maintains a gauging station . ( R . 146-147 . ) The gauging station is maintained for the purpose of determining the daily flow , and from that , the monthly and yearly ( run-off runoff ) of any stream at any point . The equipment consists of a gauge which formerly was a staff gauge but now , in general , ( -is is ) a record gauge from |
