An Experimental Study of Air-water Flows in Hydraulic Jumps with Channel Bed Roughness [PDF]

open access: yes, 2016
Hydraulic jumps occur naturally when supercritical flow transitions into subcritical flows in a sudden, extremely turbulent three-dimensional process. Research of hydraulic jumps is a challenge and to date turbulence and air-water flow measurements are ...

Extent, characteristics and policy applications of Key Biodiversity Areas

open access: yesBiological Reviews, EarlyView.
ABSTRACT A global standard for the identification of Key Biodiversity Areas (KBAs) was published 10 years ago to provide a unified set of criteria for identifying ‘sites of significance for the global persistence of biodiversity’. We review the initiative's origins, the KBA identification process, characteristics of the current network, threats, policy

Experimental Study of Free-Surface Aeration and Turbulent Processes Down an Embankment Dam Stepped Spillway [PDF]

open access: yes, 2003
Research on stepped chute hydraulics has become an important tool for operational safety and design optimisation of these structures. Detailed experimental data is scarce and limited to very steep slopes (slope>50 deg).

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

open access: yesBiological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Geomorphic restoration and stabilization of a reach of Stevens Creek [PDF]

open access: yes, 2015
This project focuses on the restoration of a 460-foot reach of Stevens Creek in Santa Clara County, California. The new design will increase the stability of stream channels, riparian system functions, and fish passage while improving or maintaining the

Numerical and Experimental Simulation of the B-jump in an Abrupt Roughened Bed of a Stilling Basin [PDF]

open access: yesمهندسی منابع آب, 2014
Hydraulic jump type stilling basins with abrupt drop are used to reduce the basin length and to ensure the start of jump at the front of basin immediately downstream of gates.
