The Automatic Throttle Hose precision in metering flow rate is not usually a critical criterion when choosing between different regulating devices for irrigation systems and storm-water retention basins. Features such as automatic operation, simple construction and low maintenance are more important.

Barrages on Alluvial Riverstion or other purposes. Such structures generally affect the morphology and regime of the rivers. Their cost and efficiency very much depend on the waterways which are generally fixed on the basis of the natural widths of the rivers or their total flood discharges. Judicious fixation of waterways as
