The mechanical resistance of trees is essential for their survival during strong wind events, enabling them to function effectively within an ecosystem. In this study, large eddy simulation employed investigate the aerodynamic characteristics isolated with various crown geometries, as well clustered tree canopies arranged in different patterns and spacing, under both normal oblique directions. For each condition, force coefficients are evaluated underlying flow mechanisms discussed, also...
Abstract The hillslope‐gully system serves as the primary contributor to both runoff and sediment yield. WEPP (Water Erosion Prediction Project) model is often applied investigate erosion characteristics at hillslope scale, demonstrating a high level of accuracy in simulating water erosion. In this study, according situ field monitoring (2014–2020) Pisha sandstone on Loess Plateau, China, total 50 rainfall events’ data were used climatic calibrate soil parameters, 11 different vegetation...
Abstract Soil salinisation is a pervasive form of land degradation posing significant threat to the global environment. Saline soil, covering roughly 10% total area, represents crucial reserve resources. The use super absorbent polymer (SAP) impacts capillary water movement through soil because its exceptional absorption and retention capabilities. SAP expected influence intricate water‐salt migration processes their redistribution within soil. This study employed column experiments...
The reliability of weather radar data in real-time flood forecasting and early warning system remain ambivalent due to high uncertainty Quantitative Precipitation Forecasts (QPF). In this study, a methodology is presented with the objective improve results application rainfall calculated three different ways. QPF forecast four typhoon events Fèngshān River Basin, Taiwan, were simulated using WASH123D numerical model. corrected physical correction technique compared direct simulation without...
The current codes and standards concerning wind loads on roof-mounted solar panels are discussed summarized. Wind pressures flat- slope-roof-mounted arrays obtained from tunnel tests compared with the recommended design values in ASCE 7-16 JIS C 8955: 2017. Different parameters, including building side ratio, aspect ratio parapet height, examined. Results show that largest flat-roof-mounted of all zones tend to be 10% 26% smaller than experimental results when normalized tributary area A n...
Shelterbelts provide essential protection against wind erosion and soil degradation, as well for fruit-bearing plants crops from strong winds. Enhancing their sheltering capabilities requires optimizing pattern orientation, defining height desired canopy shape, according to the performance. In this work, Large Eddy Simulation is employed investigate flow field windbreak effectiveness of single double-arranged shelterbelts characterized by different geometry resistance air passage neutral...
The assessment of extreme wind loading on solar arrays plays a significant role in ensuring their safe operation under strong winds. Therefore, this paper investigates the mounted flat roof by taking into account directionality effect. estimation process is conducted using situ speeds obtained from meteorological stations and coefficients tunnel tests based joint probability distribution multiple variables conditional probabilities. This allows discussion regarding how would be affected such...
Spatially arranged cable systems and inclined hangers are becoming popular in shallow pedestrian suspension bridges to improve the lateral stiffness. However, vertical motions of bridge decks under vortex shedding or loadings may still cause annoying vibrations which induce primary internal resonances deck-cable systems. This study investigates with when deck suffers from harmonic motion. A six-degrees-of-freedom (6-DOFs) mathematical model is adopted simulate linear nonlinear dynamics a...
