MONGE Y SERRANO: Flow under long two-dimensional dam sluice gate using WSPH

since the dynamic phenomena related to SWE are so gradual that correctors for vorticity or
impact have little or no effect.
• Low resolution in the water front is the main problem in the models studied, and this can
be a serious issue when modeling sediment carry-over. In these cases, interaction with the
boundary layer is key to its accuracy, so a different type of boundary particle will have to be
adopted or developed to properly interact with the uid particles.
•
Even when sediment transport is not relevant, to improve the accuracy of SPH models of
shallow water problems without requiring computationally costly increments of the number
of particles, future studies may consider creating a new type of boundary particle customized
specially for SWE-type problems.
•
The SPH scheme is well-adapted to many different open-ow hydraulics problems with
geometric discontinuities such as the general case of ow channels or partially lled piping
systems, and the convenience of not having to necessarily elaborate surface detection algori-
thms or dynamic remeshing, develops great advantages in comparison with mesh-dependent
methods such as FVM or VOF, and even hybrid approaches can be developed to attempt to
meld the positive aspects of each methodology. However, the proposal and modication of
different solid or elastic boundary equations have proven in many instances that it is one of
the most critical aspects of this method that is continually evolving and is far from being a
standard procedure applicable to any case of uid ow.
