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

open access: yesJournal 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

open access: yesJournal 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.

Thorncliffe Formation: A proglacial to subglacial lacustrine basin sequence, Greater Toronto Region, Canada

open access: yesBoreas, EarlyView.
Map of Lower sediment (LS) thickness is a surrogate for the distribution of Thorncliffe Formation (TF) and ~75% of TF thickness from the slope of Niagara Escarpment east to Brighton. Inset images show the LS sequence at the Don Valleys brickyards (DVBY) and undeformed TF sand and gravel (~15 m) below Newmarket Till (NT) at sites L and Co.

Single Slope Shore Protection as a Wave Energy Catcher

open access: yesMATEC Web of Conferences, 2018
Wave energy is being increasingly regarded in many countries as a major, promising and renewable resource. This paper presents the development of slope coastal protection as a wave energy converter by capturing sea water into the reservoir through ...

Living With Peak Discharge Uncertainty: The Self-learning Dike [PDF]

open access: yes, 2008
Although river dikes still play a key role for flood protection in the Netherlands\ud there is a growing interest for other measures to deal with larger peak discharges, such as\ud lowering or widening the floodplains.

Modeling water penetration at dam-foundation joint [PDF]

open access: yes, 2007
When fracture occurs in a concrete dam, the crack mouth is typically exposed to water. Very often this phenomenon occurs at the dam-foundation joint and is driven also by the fluid pressure inside the crack.

Irregular Wave Overtopping Rates

open access: yesCoastal Engineering 1984, 1984
Methods for estimating wave overtopping of coastal structures are reviewed and compared with the very limited available data and with each other. The different methods yield results which can vary more than an order-of-magnitude. For vertical seawalls, the U. S.

1166. Helianthus occidentalis Riddell

open access: yesCurtis's Botanical Magazine, EarlyView.
Summary Helianthus occidentalis Riddell (Compositae: Heliantheae: Helianthinae) is described and illustrated. The species' placement in the genus is commented on, as are the differences in infrageneric placement of the other species Heiser originally grouped H. occidentalis with.
