Sustained Storage and Transport of Hydraulic Gold in …
Abstract. large deposits of hydraulic gold mining sediment remain in main channels of the Bear River more than 100 years after the cessation of mining. This study examines these deposits and reevaluates Gilbert's (1917) clas- sic model of sediment transport in a symmet- rical wave that is based on hydraulic mining
