ABSTRACT:

This resource contains experimental and simulation data related to the study of flow and sediment transport around large woody debris (LWD) models.
Instructions:

The experimental data include both bathymetry and velocity measurements taken during controlled flume experiments.
Simulation data are organized by cases corresponding to different models (PM, PRW, SL, SRW) and include necessary directories to reproduce the results.
Contents:
Experiment
bathymetry: Contains STL files representing experimental bathymetric surfaces.
PRW_bathy_exp.stl: Experimental bathymetry for the porous rootwad case.
SL_bathy_exp.stl: Experimental bathymetry for the simple log case.
velocity: Excel files with velocity profiles recorded at various cross-sections of the flume.
Horizontal_no_rw.xlsx, Horizontal_prw_new.xlsx, y23_no_rw.xlsx, y23_prw_new.xlsx, y27half_no_rw.xlsx, y27half_prw_new.xlsx, y33_no_rw_corrected.xlsx, y33_prw_v2.xlsx: Velocity data at different heights and positions.
LWD_simulations:
Case directories for simulations conducted using OpenFOAM.
pm, PRW, SL, SRW: Each folder contains subdirectories (0, constant, system) and time-step data for running and analyzing simulations of different LWD models.
Usage Notes: To replicate or continue the research, users should set up OpenFOAM and compile the solver used for these simulations. The experimental data files can be used for validation or comparison with the simulated outputs.

ABSTRACT:

This resource presents models of flow and sediment transport around nature-based solutions (NBS) and bridge piers, focusing on engineered log jams (ELJs) and solid piers. Using RANS coupled with the immersed boundary method, it investigates the interactions between hydrodynamics and sediment transport to predict maximum scour depth.

Instructions: To run the simulations, users must compile the ibScourFoam solver in OpenFOAM-5.x.

Contents:
resolved_ELJ: Case directory for flow and scour modeling around a porous engineered log jam.
solid_pier: Case directory for flow and scour modeling around a solid pier.

ABSTRACT:

This repository contains simulations of grout fluid flow through a porous ballast box.

Instructions:
To run the simulations, the user needs to utilize the interFoam solver in OpenFOAM-v8 on a Linux system.

Contents:
Ballast_porosity_model: A large-scale ballast box case modeled using a porosity model.
Cone: Contains simulations of the emptying cone experiment, modeled with two cone geometries for validation purposes.
Darcy: Numerical Darcy experiments used to determine the porosity model coefficients.
Empty_box: Validation cases for flow injection in two different empty boxes.
Half_ballast: Porosity model for half of the large ballast box.
Small_ballast: Five cases with different rheological properties used to optimize grout rheology.
