Analysis of Knock Down Weir Stability Using Matlab Software

Abstract

During the rainy season, there are still puddles of water in the village due to overflowing rivers and flooding due to landslides of embankments. Therefore, it is necessary to control the water and handle it quickly and precisely. Emergency Weir, which is ready to be installed, can be used to overcome this problem. It is named Knock Down Weir as Emergency Weirs that are effective, efficient, practical, can be arranged vertically, horizontally, can be stored and reassembled with 4 Forms of Arrangement and proven by Stability value > 1.5 based on the test on the support of wall roughness: hard stone, gravel, sand, clay and using Matlab application analysis. The simulation uses a model arrangement, namely: 1). Model L filled with sand + water; 2). The model I filled with sand + water; 3). Model L filled with water; 4). Model L filled with water. The result based on the Matlab application is obtained that the arrangement of model no. 1 (L shape) is the most stable against hard rock, gravel, sand and clay as support.
