Bias Correction of Satellite Precipitation Estimation Using Deep Neural Networks and Topographic Information Over the Western U.S.

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 4, 28 February 2025.
Abstract Satellite‐based precipitation products (SPPs) have gained popularity among researchers due to their utility in hydrologic studies. Several gridded satellite‐based precipitation products with global coverage, such as the Integrated Multi‐satellitE Retrievals for GPM (IMERG) and the Precipitation Estimation from Remotely Sensed Information using

The Study of Water Content on the Coal Loading Performance of Thin Coal Seam Shearer Drum by Discrete Element Method (DEM)

Engineering Reports, Volume 7, Issue 1, January 2025.
Loading methods, helical angles, and rotation speed of drum have significant effects on the loading rate of drum. In this study, Discrete Element Method (DEM) is used to study what effects of these several factors have on the loading rate under different water contents.

Macro–Microscopic Mechanical Study of Clay–Structure Interface Shear Behavior Using Direct Shear Testing and DEM Simulation

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
Understanding the interface shear behavior between clay and structures is crucial in geotechnical engineering. The mechanism of the roughness effect in the shear process between the clay and structures was studied to reveal the macroscopic and microscopic interface shear behavior.

Choosing the Optimal Global Digital Elevation Model for Stream Network Delineation: Beyond Vertical Accuracy

Earth and Space Science, Volume 11, Issue 12, December 2024.
Abstract Satellite‐derived global digital elevation models (DEMs) are essential for providing the topographic information needed in a wide range of hydrological applications. However, their use is limited by spatial resolution and vertical bias due to sensor limitations in observing bare terrain.

Morphometric analysis and watershed delineation of the Karnaphuli river basin: A comparative study using different DEMs in Chittagong, Bangladesh

River, Volume 3, Issue 4, Page 426-437, November 2024.
Abstract The present study aimed to delineate a robust watershed boundary and extract its morphometric parameters in the Karnaphuli watershed, Bangladesh, using different digital elevation models (DEMs). Two DEMs, the shuttle radar topographic mission (SRTM) and the terra advanced spaceborne thermal emission and reflection radiometer (ASTER), were ...
