Depth Matters: Lake Bathymetry Selection in Numerical Weather Prediction Systems

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 2, 28 January 2025.
Abstract Lake surface conditions are critical for representing lake‐atmosphere interactions in numerical weather prediction. The Community Land Model's 1‐D lake component (CLM‐lake) is part of NOAA's High‐Resolution Rapid Refresh (HRRR) 3‐km weather/earth‐system model, which assumes that virtually all the two thousand lakes represented in CONUS have ...

Numerical Analysis of Pile‐Supported Reinforced Embankments in Deep Soft Soil Regions Based on Soft Soil Creep Parameter Optimization

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
When analyzing the engineering characteristics of pile‐supported embankments in deep soft soil regions, the creep behavior of soft soils cannot be overlooked. In previous numerical analyses, empirical formulas were often used to determine related parameters, which limited the accuracy of the calculations.

Study on the shear and deformation characteristics of geogrid-reinforced gravelly soils based on large-scale triaxial tests

Frontiers in Earth Science
Geogrid reinforcement has a limiting effect on the lateral deformation and thus improves the shear strength of the soil, the overall strength of the soil and the overall stability of the corresponding geotechnical structure.
