An analytical model for bore-driven run-up [PDF]
, 2008 We use a hodograph transformation and a boundary integral method to derive a new analytical solution to the shallow-water equations describing bore-generated run-up on a plane beach.

Numerical Approach for Predicting Levee Overtopping in River Curves Through Dimensionless Parameters
Applied SciencesRecent climate changes have led to an increase in flood intensity, often resulting in frequent levee overtopping, which causes significant human and property damage.

The SSG Wave Energy Converter: Performance, Status and Recent Developments
Energies, 2012 The Sea-wave Slot-cone Generator (SSG) is a Wave Energy Converter based on the wave overtopping principle; it employs several reservoirs placed on top of each other, in which the energy of incoming waves is stored as potential energy.

Laboratory design-studies of the effect of waves on a proposed island site for a combined nuclear power and desalting plant [PDF]
, 1966 There were four major objectives to this investigation: 1) the determination of the degree of stability of the island face when constructed of armor units of various weights; 2) the run-up for a two-dimensional wave system impinging on the island face; 3)

Journal of Systematics and Evolution, EarlyView.We present the most densely sampled phylogeny of Carex section Lupulinae to date (107 specimens) and describe herein a new cryptic species for science from the southern United States, which is locally abundant and found in well‐explored and densely populated areas. Combining DNA sequences with morphometric data obtained from 299 samples, we Demonstrate

Journal of Marine Science and Engineering, 2020 The average overtopping discharge is an important parameter for the design and reinforcement of dikes. Rock armour on the waterside slopes and berms of dikes is widely used to reduce the wave overtopping discharge by introducing slope roughness and ...

Embankment overtopping protection systems [PDF]
Acta Geotechnica, 2014 For the last decades, the design floods of numerous embankment reservoirs were re-evaluated, and the revised spillway outflows are typically larger than those used in the original designs. As a result, a number of overtopping protection systems were developed for embankments and earthfill dams, with applications encompassing river dykes, coastal ...

Beaver dam analogues increase amphibian breeding occupancy and bat activity
Restoration Ecology, EarlyView.Abstract Introduction Beavers are ecosystem engineers that can create ponds, increase stream complexity, and enhance biodiversity. To mimic these and other effects, restoration practitioners increasingly install beaver dam analogues (BDAs) in degraded streams.

The implementation of sinusoidal PWM on single phase 5-level cascaded H-bridge multilevel inverter [PDF]
, 2013 In the new millennium era of technology, modern industrial devices are mostly based on electronic devices that are very sensitive to harmonics. The needs for a free-harmonics and high rating power source is extremely increased in the past few years ...
