A numerical investigation of irregular wave overtopping on a 2D fixed overtopping wave energy converter

Engineering Applications of Computational Fluid Mechanics
Overtopping wave energy converters (OWECs) are designed to capture the energy from wave overtopping and transform it into clean and renewable electricity. The present paper numerically investigates irregular wave overtopping on a simplified 2-dimensional

Wave Overtopping at Sea Dikes on Shallow Foreshores: A Review, an Evaluation, and Remaining Challenges

Journal of Marine Science and Engineering, 2023
Wave overtopping is a critical parameter in the design of coastal defense structures. Nowadays, several empirical formulations based on small-scale experiments are available in the literature to predict the mean overtopping discharge at dikes on shallow ...

Is a plant truly plastic? Nutrients and neighbours induce trait‐specific responses, but performance depends on response direction

Oikos, EarlyView.
Plants live in a heterogeneous world, where nutrient and neighbour distributions vary in space and time. Plants can respond to this variation through plastic responses in individual organs, which are assumed to be coordinated among traits to support a coherent, adaptive strategy, maintaining plant growth in varying environments.

Bias in Peak Flood Discharges: Are Our Bridges and Culverts Undersized?

River Research and Applications, EarlyView.
ABSTRACT Reliable methods for peak discharge predictions at ungaged locations are required for infrastructure design and floodplain management. For decades, a standard practice in the United States has been to utilize US Geological Survey regional regression equations (StreamStats) as a singular method. However, implementation of multiple methods, such

COMPARISON OF NUMERICAL AND EXPERIMENTAL RESULTS FOR OVERTOPPING DISCHARGE OF THE OBREC WAVE ENERGY CONVERTER [PDF]

Journal of Engineering Science and Technology, 2017
OBREC is the latest innovation of overtopping wave energy converter (WEC) which is coalesced with the rubble mound breakwaters. The acquisition of wave overtopping in a front reservoir and consequently releasing process through turbine is the concept of ...

Wave Transmission by Overtopping

Journal of the Waterways, Harbors and Coastal Engineering Division, 1972
This report presents a semi-empirical theory for ocean wave transmission past breakwaters by overtopping, based on an evaluation of the energy content of the overtopping water. While several coefficients are subject to further investigation, the data show that the general form of the equations developed is correct.

Spectral characterization of plant diversity in a biodiversity‐enriched oil palm plantation

Remote Sensing in Ecology and Conservation, EarlyView.
How well can airborne imaging spectroscopy detect plant diversity in vertically complex agroforestry systems? We tested this in a biodiversity‐enriched oil palm plantation in Sumatra, Indonesia, using high‐resolution hyperspectral data. We calculated spectral alpha and beta diversity and compared them to field‐based plant diversity.

Experimental study on scour and erosion of blocked dam

Water Science and Engineering, 2012
This paper presents new experimental data of the erosion rate and sediment transport rate during the processes of dam break caused by overtopping. In order to study the headcut migration, the erosion coefficient was calculated and its peak value was ...
