Modeling and Analysis of Geo-disaster Problems Using the SPH Method
TL;DR: Abdelrazek et al. as discussed by the authors developed a mesh-free particle method to simulate free surface flow problems and used it to simulate three benchmark tests, (Dam breaking, collapse of a water column with a rigid obstacle, and dam break on a wet bed).

TL;DR: In this paper, the concept of a fractional volume of fluid (VOF) has been used to approximate free boundaries in finite-difference numerical simulations, which is shown to be more flexible and efficient than other methods for treating complicated free boundary configurations.
