Debris flow is a kind of geological disasters occurred in a mountainous area and can cause serious impacts on human lives, infrastructure and houses. Therefore, the potential exposure to this hazard may occur in the surrounding area. This paper assesses some recent noncommercial Smoothed Particle Hydrodynamic (SPH) package for debris flow. SPH as a Lagrangian method, in recent decade SPH showed to be effective in solving in engineering problems involving numerical formulation. The paper considers the features and capabilities can be offer from the non-commercial SPH package that are available and accessible for researcher related to debris flow, solid fluid interaction and so on. Finally, researcher may consider the SPH package based on the suitability of the study as well as the accuracy of the experimental test that have been compared with SPH package.
Water Resources Section at School of Civil Engineering, Universiti Sains Malaysia have involved more than 20 projects in pump sump physical modeling, 4 projects in hydraulic spillway study and more than 20 projects related to hydraulic physical model. The total cost of overall projects involved is more than 1 million USD. Hydraulic physical modeling has proven to be important and efficient tool in conceptual as well as detailed hydraulic design. Pump sump model provide effective solution to complex hydraulic problems with unmatched reliability. Meanwhile spillway study is often necessary to determine the possible occurrences of hydraulic jumps, splashing over the site walls and undesired flow vortices. This research can be done accurately because the equipment is complete and sophisticated. Problems related to hydraulic physical model can be solved wisely and accurately with aid of accurate design, data collection and data analyses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
