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.

Prediction of Mean Overtopping Discharge at Vertical Seawalls Using MLR and GLM Statistical Approaches

open access: yesInternational Journal of Maritime Technology, 2015
Wave overtopping at breakwaters is one of their essential hydraulic characteristics when determining the design crest level. This study concentrates on developing a new practical formula on predicting wave overtopping, by implementing two different ...

Spatial distribution of regular wave overtopping on landscape revetment during typhoon landfalls

open access: yesApplied Ocean Research
Typhoons raise nearshore water levels and generate large waves, posing significant wave overtopping risks to low-crested revetments designed with hydrophilic considerations.

Integrative taxonomy supports DNA barcoding in revealing an abundant cryptic species in the United States Coastal Plain

open access: yesJournal 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

Beaver dam analogues increase amphibian breeding occupancy and bat activity

open access: yesRestoration 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 SSG Wave Energy Converter: Performance, Status and Recent Developments

open access: yesEnergies, 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.

Seismic Design of Concrete Dams: An Integrated Risk‐Informed Performance‐Based (RIPB) Framework

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 5, Page 1019-1049, 25 April 2026.
ABSTRACT This paper advances the integration of risk‐informed principles into the seismic design of dams—a domain long guided by standards‐based, largely deterministic approaches. While performance‐based earthquake engineering is well established for buildings and bridges, its systematic adoption in dam engineering remains limited. We first address two

Global Hydroclimatic Controls on Multithread River Dynamics

open access: yesAGU Advances, Volume 7, Issue 2, April 2026.
Abstract Most large rivers in densely populated areas split flow into multiple channels, forming interconnected pathways called threads. Multithread rivers are sensitive to hydroclimatic changes, yet understanding their dynamics is challenging due to the lack of robust metrics to characterize their evolution.
