Abstract
Theories of dam construction that were created eventually laid the groundwork for dam safety, allowing for the design of higher-quality dams to be built. Dam engineers continued to experiment with new technology to build dams in a safer, more cost-effective, and environmentally friendly manner. The Discrete Particle Method (DPM) is commonly used in various study. Objective of this study is to identify a different velocity of different particles influence at ogee dam spillway using Discrete Particle Method (DPM). Simulation of 1:1 and 1:40 scaled model and experimental 1:40 scaled model had been done. This study presents a validation of particles velocity on 1:40 scaled ogee dam using Particle Image Velocimetry (PIV). Three different types of particles namely as silt, sand and gravel was use in DPM simulation. The results indicate a pattern of particle velocity peak at certain point. Percentage different for 1:40 scaled simulation and PIV experimental is less than 10%. � 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
