Introducing high-order response surface method for improving scour depth prediction downstream of weirs

Applied Water Science
Scour depth downstream of weirs is considered one of the most important hydraulic problems, which greatly influences the stability of weirs. Recently, artificial intelligence (AI) methods have become increasingly popular in modeling hydraulic variables ...

Prediction of Scour Hole Geometry Downstream of Ski-Jump Spillways Using Novel Intelligent Computational Machine Learning Models

Forecasting
The ski-jump spillway is an energy-dissipating structure that discharges extra water beyond the dam’s capacity. The scour process occurs below spillways due to the collision of the water jet with high energy.

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

Archaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...

One‐Stage Combined Hip Arthroscopy and Derotational Femoral Osteotomy on a Postless Traction Bed

Arthroscopy Techniques, EarlyView.
Abstract Abnormal femoral torsion is associated with labral and chondral tears, hip pain, and early onset arthritis. Derotational femoral osteotomy (DFO) is the surgical treatment of choice to correct femoral torsional deformity, restore normal hip joint mechanics, and improve clinical outcomes.

Downslope erosion response of engineered landform to upslope runoff in loess hilly region

Shui kexue jinzhan, 2015
In order to figure out the quantitative influence on wash-scour erosion at the bottom of high and steep slope of engineered landform caused by upslope runoff,the typical abrupt slope (36°) of engineering deposits along the expressway from Shenmu to Fugu ...

Standardized Patient Positioning and Operating Room Setup for Ankle Arthroscopy: A Technical Note

Arthroscopy Techniques, EarlyView.
Abstract This technical note describes and standardizes patient positioning and operating room setup for ankle arthroscopy in supine, prone, and lateral decubitus positions. The proposed configuration emphasizes ergonomic optimization, efficient cable management, and improved workflow for both surgeon and assistant.

Effect of the Correlation between Hydraulic Parameters on the Reliability Analysis of a Riprap Designed around Bridge Pier

علوم آب و خاک, 2021
One of the most common and practical methods in controlling the local scour around bridge pier is to place a protective riprap layer. Due to various uncertainties in the design of this countermeasure method, in the present study, the reliability analysis
