Effect of stilling basin shape on the hydraulic characteristics of the flow downstream radial gates

open access: yesAlexandria Engineering Journal, 2010
Barrage regulators are considered as one of the most important projects in the Egyptian irrigation practice, which is obvious by its controlling of the released discharge and both of upstream and downstream water levels. In the present time, the ministry

A dimensional analysis of supersaturated total dissolved gas dissipation [PDF]

open access: yes, 2015
Elevated levels of total dissolved gas (TDG) may occur downstream of dam discharges, leading to increased incidence of gas bubble disease in fish. Accelerating the dissipation of supersaturated TDG in the downstream river can mitigate this negative ...

When the River Runs Low: Heterogeneous Impacts of Transportation Disruptions on Local Grain Basis

open access: yesAgribusiness, EarlyView.
ABSTRACT A substantial share of U.S. soybean and corn exports from the Midwest moves by barge along the Mississippi River system to export terminals in the Louisiana Gulf. Transportation costs between Midwestern grain elevators and export terminals create a wedge between prices at these locations, and shocks to these costs are partially passed on to ...

Evaluating the Hydraulic Performance of USBR II Stilling Basin with Rough Bed

open access: yesTikrit Journal of Engineering Sciences
Stilling basins are built in conjunction with dams, weirs, and gates to dissipate the high kinetic energy of incoming flow and prevent severe scouring of the downstream riverbed.

B-f jump characteristics in smooth sloping beds [PDF]

open access: yesمهندسی منابع آب, 2019
Beacause of the hydraulic jump unstable behavior in adverse-slope stilling basins downstream of sloping beds, the jump toe is transmitted on sloping bed. Therefore, formation of the B-F jump is common in practice.

Numerical and experimental models applied to an ogee crest spillway and roller bucket stilling basin

open access: yesRBRH, 2020
Traditionally, reduced physical models are used to allow control, instrumentation and experimental evaluation of flow. More recently, computational fluid dynamics (CFD) has emerged as a tool that allows numerical modeling of flows and can complement the ...

Modelling Stilling Basins for Sewage Networks

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
Abstract Concrete elements play an effective role in stilling basin design in terms of enhancing the dissipation of energy to prevent immoderate scouring of downstream structures. Proper appurtenances, such as wedge-shaped splitter blocks, baffle walls, inverted t-sections, rectangular walls, inverted L sections, and impact walls, are ...

Long‐term prognosis is associated with residual disease after neoadjuvant systemic therapy but not with initial nodal status

open access: yesBJS (British Journal of Surgery), EarlyView., 2020
This long‐term follow‐up study determined survival rates in a Swedish national cohort of 417 patients with breast cancer who all had neoadjuvant systemic therapy (NAST). Sentinel lymph node biopsy (SLNB) was performed before NAST in clinically node‐negative and after NAST in clinically node‐positive patients.
