title: One-to-Ten Scale Evaluation of Coastal Structure Shapes, in Advancing Knowledge in Water - Shell Structure Interaction Through Discovery of Efficient Hydrodynamic and Structural Thin-shell Forms

description: This dataset is derived from an experimental program of 1:10 scale models of coastal structures with varied geometric configurations tested in the CHERL wave flume at Stony Brook University. Five distinct structural geometries are included: a cubic box, a box girder with overhangs, two continuous box configurations with concave and convex side-wall transitions, and a hypar box. The dataset involves a range of regular wave conditions, encompassing variations in wave height, period, and steepness, combined with multiple structural elevation levels (semi-submerged, still water level, and elevated) to represent realistic coastal hazard scenarios.

The dataset comprises measurement results of horizontal and vertical forces as well as detailed wave time histories for all test scenarios. Force and hydrodynamic data were acquired using precision-calibrated sensors and digitized at sampling rates sufficient to capture necessary structural responses. Comprehensive quality control procedures were applied to identify and correct anomalies, after which the dataset was systematically organized by test series for accessibility. The dataset offers a strong basis for validating numerical and physical models, supporting structural design optimization, and/or developing data-driven predictive frameworks, in order to assess the influence of coastal structure shapes on wave-induced loading.
description: This project aims to advance the fundamental knowledge of wave-shell structure interaction by means of discovering efficient hydrodynamic thin-shell structural forms that have broad application to coastal structures. Physical experiments are conducted to study how specific structural parameters and wave characteristics influence wave-induced loads, in order to identify structural geometries that reduce wave forces while maintaining structural performance. The hazards of interest are coastal hazards, including storm surge, high tides, and elevated water levels during extreme weather events.

The project includes two experimental programs conducted in the water flumes at Stony Brook University and Oregon State University, both using scaled models of different structural configurations. The models are exposed to waves with varied heights, periods, and steepness, and positioned at different elevations—semi-submerged, still water level, and elevated—to simulate a range of hazard scenarios.

The project contains measurement results of wave forces, wave elevations, fluid velocities, hydrodynamic pressures, etc. The data can benefit coastal engineers, designers, and researchers by enabling reproducibility of experiments, validation of computational models, and development of data-driven tools for predicting wave–structure interaction. It also supports the creation of optimized structural forms for future coastal defense systems, offering a resource that can generate new studies and improve resilience strategies in coastal engineering.
