Depth Design for Rectangular Stilling Well with Oblique Water Intake

Renmin Zhujiang, 2022
When the topography conditions cannot satisfy the needs of the length of the stilling pool during traditional bottom-flow energy dissipation,the energy can be dissipated by increasing the depth and width of the pool.To obtain suitable depths for a ...

SOME STUDIES ON THE HYDRAULIC JUMP AND THE SUBMERGED EFFLUX

Transactions of the Japan Society of Civil Engineers, 1960
In this paper, the author deals with the phenomena of hydraulic jump and submerged efflux. The experimental and the theoretical work are divided into four phases, the first of which derived the equation of sequent depth from continuity and momentum equations in sloping channels. In the second phase, the wave length and the amplitude of undular jump are

A novel approach for in situ benthic habitat characterization

Limnology and Oceanography: Methods, EarlyView.
Abstract Habitat heterogeneity is a key driver of temporal and spatial variability of subtidal marine benthic biodiversity. However, this makes it a challenging environment in which to measure and quantify the factors driving biodiversity in a consistent manner.

Bed‐level tools for monitoring erosion and accretion patterns: Flume validation and field testing

Limnology and Oceanography: Methods, EarlyView.
Abstract Monitoring short‐term changes in surface sediment elevation is fundamental to understanding erosion, transport, and deposition dynamics in shallow coastal environments. However, commonly used field approaches, such as horizontal markers, sediment erosion tables, subsurface sediment plates, or erosion pins, are not always cross‐validated under ...

Iron(III) ion reinforced P(NiPAAm‐co‐AA) beads as tunable smart organogels

Polymer International, EarlyView.
Macroporous beads of PNiPAAm‐co‐AA copolymers were further crosslinked by iron(III) ions. The resulting beads are mechanically robust and reversibly responsive to a change of solvent from ethanol to ethyl acetate with half‐lives in the range of minutes.

Within‐tree spatial heterogeneity of sap flow velocities and wood properties and its effect on the uncertainty of tree level sap flux estimates

PLANTS, PEOPLE, PLANET, EarlyView.
As forests are important for biodiversity and recreation and provide vital resources globally, it is essential that their health can be accurately monitored, for example, by using sap flow probes to measure tree water uptake. We investigated whether sap flow measurements might differ at various locations within the same tree due to variation in wood ...

The Effect of Submerged Vanes on Improving Hydraulic Jump Characteristics and Investigating the Role of Attack Angle [PDF]

علوم آب و خاک
One of the ways to improve the characteristics of the hydraulic jump in the stilling basin is to use natural and artificial roughness. Recently, due to the advantages of immersed plates compared to other non-continuous artificial roughness, such as the ...

Hydraulic justification of the water outlet conduit parameters in connection with the Don Main Canal reconstruction (2nd phase of the II reconstruction stage)

Мелиорация и гидротехника
Purpose: calculation substantiation of the Don Main Canal outlet conduit parameters, which would ensure reliable and safe operation, as well as reduced risks of flooding and damage, for their adaptation to new hydraulic conditions.

Deep Reinforcement Learning‐Based Control for Real‐Time Hybrid Simulation of Civil Structures

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Real‐time Hybrid Simulation (RTHS) is a cyber‐physical technique that studies the dynamic behavior of a system by combining physical and numerical components that are coupled through a boundary condition enforcer. In structural engineering, the numerical components are subjected to environmental loads that become dynamic displacements of the ...
