ANALYSIS OF PHYSICAL MODEL RUBBER WEIR CONTAIN WATER AS MOTION WEIR FOR FLOOD AND ROB HANDLING

The aim of this study is to evaluate the existing conditions of flood and rob disasters, prepare closed circuit water canals for experiments, analyze the characteristics of water-filled rubber weirs so that weir models can be used as appropriate technology, and carry out stability analysis on currents. The research method used several variations of model simulations to find a correlation between upstream water level elevation and a simulated elevated water level elevation. The variables studied are weir loads, mud, earthquake and hydrostatic stresses. The laboratory test results obtained that the elevation is obtained in the safety factor of 1.603 and the downstream elevation is found to be a safety factor of 1.597 in the condition of the flood face.
