Hydraulic Characteristics on Flow of Elbow Parts of Snow-Removing Ditches

Abstract

A problem related to the capacity of snow removing by flowing water in ditch is treated. In this experiment, crushed ice was used instead of snow. The scale of the region of separation has been measured for the various plane forms of the elbow parts of ditch. The rise in ditch stage has been analyzed theoretically, and compared with the experimental values. The both results agreed approximately. The energy losses of the flow on the elbow parts of ditch is estimated. The limiting conditions of crushed ice trasportation by flowing water through the elbow parts of ditch has been studied experimentally.
