Effect of initial water content on soil failure mechanism of loess mudflow disasters

Frontiers in Ecology and Evolution, 2023
The frequency of mudflow disasters induced by rainfall in the Loess Plateau is increasing with the occurrence of global warming. The initial water content is one of the basic properties of soil, which affects the initiation of loess mudflow. In this work,

Analysis of and Reduction in Noise in Current Measurement of XCP under the Laboratory Condition

Sensors, 2022
Expendable current profiler (XCP) is one of the most vital devices detecting ocean currents. Compared with other methods, the expendable feature makes trials with XCP much faster and more hidden, while the accuracy of XCP is considerably influenced by ...

MODEX: Laboratory experiment exploring sediment spreading of a mound under waves and currents [PDF]

, 2019
The dispersal of sand from submerged mounds in the nearshore is driven by the interplay of processes such as converging and recirculating flows, changing roughness, bed slope effects and wave focusing/refraction.

Positive Surge Propagation in Sloping Channels [PDF]

, 2017
A simplified model for the upstream propagation of a positive surge in a sloping, rectangular channel is presented. The model is based on the assumptions of a flat water surface and negligible energy dissipation downstream of the surge, which is ...

Construction of Meandering Channel and Its Application in Investigation of Bed Topography around Hydraulic Structures [PDF]

Journal of Hydraulic Structures
Considering river behavior analysis, numerous researchers worldwide have so far attempted to construct experimental channels. Beginning from the upstream side, the channel respectively consisted of an 8-meter-long straight path, two consecutive 180 ...

Anabranching and maximum flow efficiency in Magela Creek, northern Australia [PDF]

, 2004
Anabranching is the prevailing river pattern found along alluvial tracts of the world's largest rivers. Hydraulic geometry and bed material discharge are compared between single channel and anabranching reaches up to 4 times bank-full discharge in Magela

EMG‐Driven Telemetry and Inference System for Fish: Pose Reconstruction and Flow Sensing

Advanced Intelligent Systems, EarlyView.
This work introduces an electromyography (EMG)‐driven telemetry framework that reconstructs body pose and infers hydrodynamic conditions in freely swimming fish. A custom 16‐channel archival system records intramuscular EMG, enabling deep‐learning models to decode joint kinematics, classify flow regimes, and reveal channel‐efficient sensing strategies.
