LIDAR Scanning as an Advanced Technology in Physical Hydraulic Modelling: The Stilling Basin Example

Remote Sensing, 2021
In hydraulic engineering, stilling basin design is traditionally carried out using physical models, conducting visual flow observations as well as point-source measurements of pressure, flow depth, and velocity at locations of design relevance.

Experimental study on the body parameters of the two-stage stilling basin in low Froude number flow

Shui kexue jinzhan, 2018
Under the condition of a low Froude number (Fr) flow, the two-stage stilling basin is an effective way of solving the problem of energy dissipation. However, to date, there have been many applications of the two-stage stilling basin, but little research ...

Numerical modeling of hydraulic jumps at negative steps to improve energy dissipation in stilling basins

Applied Water Science, 2023
The performance of stilling basins including a negative step was analyzed addressing its effect on the energy dissipation efficiency, dimensions and structural properties of the hydraulic jump, streambed pressures and pressure fluctuations. Six different

Simplified procedure for determining of drop and stilling basin

Ain Shams Engineering Journal, 2014
Drops are used to effectively dissipate the surplus energy of the water flow. A closed conduit drop conveys water and stills it at its downstream. I-type pipe drop is one kind of the closed conduit drops which is used in irrigation networks as a typical ...

Investigation of Scour Depth Downstream of Stilling Basin for the Case of B-Jump [PDF]

علوم و مهندسی آبیاری, 2016
Scour downstream of hydraulic jump stilling basins can damage the surrounding area and can cause failure of the structure itself. Because of the study of such phenomenon has attracted the attention of researchers in the past.

Machine Learning Based Prediction of Hydraulic Jump Lengths in Stilling Basins for Barrages and Low-Head Hydraulic Structures

Mehran University Research Journal of Engineering and Technology
A hydraulic-jump-type stilling basin is a popular choice for energy dissipation, where the high-velocity, supercritical flow from a dam spillway transitions into a low-velocity, subcritical flow.

Laboratory study of stilling basin using trapezoidal bed elements

Przegląd Naukowy Inżynieria i Kształtowanie Środowiska, 2020
When designing dam spillway structures, the most significant consideration is the energy dissipation arrangements. Different varieties of baffle blocks and stilling basins have been used in this context. However, the hydraulic jump form of stilling basin

Resolving the Cu(bdc) Conundrum: Identifying Non‐Porous Packing of Prototypical Coordination‐Network Thin Films Combining Advanced Diffraction Techniques and Computational Modelling

Advanced Functional Materials, EarlyView.
Solution‐processed Cu(bdc) forms prototypical MOF thin films for which a multitude of not fully satisfactory structural models have been suggested. Combining rotating grazing‐incidence diffraction and X‐ray reflectivity on two complementary samples with density‐functional theory, we first discard the previously suggested models and then identify a non ...
