“Walk the Land, Before You Talk About the Land”: TEK‐Based Conservation Monitoring Invalidates Caribou Extirpation Status Assigned by British Columbia and Canada

Conservation Letters, Volume 18, Issue 5, September/October 2025.
ABSTRACT The loss of species represents critical ecological events with far‐reaching implications for conservation biology. Accurate determinations of population status are therefore essential. Erroneous declarations of extinction or extirpation can lead to legal and policy inertia, the premature termination of recovery efforts, and the ongoing ...

Discharge coefficient of sharp-crested side weir in trapezoidal channel with different side-wall slopes under subcritical flow conditions

, 2014
© 2014 John Wiley & Sons, Ltd. In this study, a comprehensive experimental study was performed to find an equation for the estimation of flow discharge over a sharp-crested side weir in a trapezoidal channel.

Effect of Managing Tributary Flows on Flood Risk in Transitional Low‐Gradient River Systems

Journal of Flood Risk Management, Volume 18, Issue 3, September 2025.
ABSTRACT Flooding in low‐gradient river systems, particularly, within inland‐to‐coastal transitional settings, poses significant risks to both human and natural systems due to complex flow dynamics and the convergence of riverine, tidal, and storm‐driven flooding regimes.

Discharge Coefficient of Sharp-Crested Trapezoidal Labyrinth Weirs

International Journal of Electronics, Mechanical and Mechatronics Engineering, 2016
Labyrinth weirs provide an effective means to increase the spillway discharge capacity of dams and are often considered for renovation projects required due to an increase in expected flood inflow to the reservoir of an existing dam. Free crest spillways are hydraulically efficient and safe in operation. Since their discharge capacity

Effects of Hydrological and Catchment Biophysical Factors on Baseflow Dynamics in Two Neighbouring Micro‐Catchments of the Andean Ecosystems

Hydrological Processes, Volume 39, Issue 7, July 2025.
While the convergence of the flow duration curve indicates similar behaviour as baseflow decreases, Shigual can sustain slightly higher minimum flows during extremely dry periods compared to Anduy. The mean baseflow indices of both catchments are similar, but Anduy faced a sharp baseflow recession, whereas Shigual exhibited a more stable baseflow ...

Hydraulic Control of Submarine Glacial Melt in Greenlandic Fjords

Journal of Geophysical Research: Oceans, Volume 130, Issue 7, July 2025.
Abstract Ocean‐driven submarine basal melt of the Greenland Ice Sheet remains a major source of uncertainty in climate projections of future sea level rise based on ice sheet modeling. State‐of‐the‐art parameterizations focus on the properties of the ocean water reaching the marine‐terminating glaciers, processes at the ice‐ocean interface and ...

Experimental investigation of discharge coefficient over novel kind of sharp-crested V-notch weir

, 2017
Thin-plate weirs are the simplest and least expensive devices, which frequently have been employed in many water projects. In this research, a unique type of Sharp-Crested V-notch weir, entitled SCVW, has been introduced. The hydraulic characteristics of

Breaching of Homogeneous Dams With Internal Drainage System

Water Resources Research, Volume 61, Issue 7, July 2025.
Abstract The present work addresses the influence of internal drainage systems on failure by overtopping of earth dams. It is based on data collected in six homogeneous dam breach laboratory experiments. Different drainage systems were tested: (a) toe drain only and (b) complete internal drainage system—chimney filter, horizontal blanket and toe drain.

The Validation of Rectangular Sharp Crested Weir Flow using ANSYS – FLUENT

Zanco Journal of Pure and Applied Sciences
A weir is a structure consisting of an obstruction such as a dam that built across the open channel to change its flow characteristics. In the present study, a total 12 experiments were done in the laboratory of civil engineering department inside an ...
