This is a source code for coupled finite particle method and smooth particle hydrodynamics. The source code can be used to test 2D regular waves contained in the paper "Coupled finite particle method for simulations of wave and structure interaction. Coastal Engineering, 2018". The code is compiled by 2013 Visual Studio with the C language.

Experimental data of scale experiments performed at the beach. Two series of experiments were performed with cuboid scale models of various sizes, to determine how the size of aeolian depositon and erosion patterns around beach buildings depends on building geometry. Series A consisted of cuboid scale models of buildings, placed at the beach for approximately 1 day. These scale models ranged in size from 0.3x0.5x0.3 m (WxLxH) to 1x2x0.6 m. Measurements were taken at the end of each day (each experiment). Serie B consisted of a shipping container (2.5x12x2.5 m) and a small scale model (0.5x2x0.5 m), placed simultaneously at the beach for more than two months. Measurements were taken at six different days during this period. Deposition and erosion around buildings are measured using structure-from motion (SfM) photogrammetry. Data contains: Raw photos used for SfM photogrammetry Photogrammetry files Digital elavation models (DEMs) and orthophotos of the deposition and erosion around scale models. Processed data from the automatic detection of deposition edges: binarized orthophotos (deposition/rest) and the edges of the deposition areas Time lapses of the the experiments Wind speed and direction measurements Measured deposition sizes

It was filmed during Experiment 13 (far field Shields parameter \theta=0.126) from the study of Sui et al. (2021). Snapshots from this video were utilized to produce Figure 15 within the paper. This video demonstrates three-dimensional scour beneath a submerged pipeline in a steady current from an experiment conducted in the Hydraulics Laboratory at the Technical University of Denmark, Department of Mechanical Engineering. The video demonstrates clear differences in the amount of sand put into suspension during the primary (initial, rapid) and secondary (slower) stages of span migration during the 3D scour beneath a submerged pipeline. There is much more sediment put into suspension during the primary stage. This visualization thus supports the contentions of Cheng et al. (2009), who asserted that the initial (rapid) stage of scour span migration is likely induced by a strong three-dimensional flow, driven through the relatively small (short and thin) initial scour hole by a relatively large pressure gradient associated with the contracted flow beneath the cylinder. Cheng et al. (2009) likewise stated that as the scour span progresses along the cylinder, and the local scour at mid-cylinder (i.e. the position of initialized scour, y = 0), reaches equilibrium, that the driving pressure gradient will become smaller, and the flow will locally become much more two-dimensional. They asserted that the slower secondary migration stage would hence coincide with the disappearance of the additional scouring mechanisms associated with the initial stage.
