Flows over hydraulic structures, such as weirs or spillways, can be modelled using different techniques. New models such as SPH or PFEM are becoming more and more popular. These models are particle and/or meshless and consequently require a lot of computational power. Other methods such as VOF also require a lot of computational time. In the frame of 2-D vertical flows, other techniques use much less computation time. For irrotationnal flows, solving the Laplace equation can be done very efficiently. The difficulty of this method lies in the definition of boundary conditions. The free-surface, which is naturally determined when using Lagrangian methods, needs a heavy iterative solving due to its non-linear nature when expressed in the frame of the Laplace equation. This paper will present an original technique that allows a quicker and easier determination of the free-surface. An irregular mesh for boundaries is used and discussed. The method is validated with analytical solutions and experimental measurements. [less ▲]

The SPH method (smoothed particle hydrodynamics) is a numerical meshless, particle and Lagrangian method. It is used in a lot of fields of engineering, such as solids mechanics, hydraulics and astrophysics. The medium is represented thanks to a set of particles that have an influence on each other. First of all, the positioning of the method is discussed. The SPH method is compared to some existing numerical methods. Its advantages and drawbacks are introduced. Its particle, meshless and Lagrangian characteristics are compared to other existing methods. The basics of the method are explained through the integral representation of a function and the particle approximation. Moreover, some smoothing functions are analysed. The SPH method being Lagrangian, the Navier-Stokes equations must be written in the Lagrangian formalism. After this, the SPH method can be applied to the equations of continuity and of conservation of momentum. Some practical issues linked to the SPH method such as the neighbours search, the equations of state or the boundary conditions are discussed. Then, the practical implementation of the method and of the chosen options is explained in details. An object-oriented programming was chosen for its advantages in comparison to a classical sequential implementation. Finally, the implemented program is tested and commented. Its advantages are highlighted and its drawbacks are discussed and explained. There are a lot of test cases presented. They include some validation tests (dam breaks, particles fall, etc.), some test cases used to compare the options of the program and other tests present the possibilities of the code. [less ▲]
