Approaches for Laboratory Automation of Hydraulic Experiments on Alluvial Bed

Abstract

Hydraulic experiments on alluvial bed have various conditions to be controlled and produce many data to be measured and processed. These laborious works compelled us to approach laboratory automation that faciliates the execution of a large number of runs and observations under wellcontrolled conditions. A personal computer control' system of discharge and water surface slope that made it feasible to conduct experiments under complicated unsteady conditions is explained. A traverser measurement system with a sand surface detector and a water level guage improved to be compatible to personal computers was applied to a few kinds of experiments very successfully.
