Nonstationarity is one major issue in hydrological models, especially design rainfall analysis. Design rainfalls are typically estimated by annual maximum (AMRs) of observations below 50 years many parts the world, including South Korea. However, due to lack data, time-dependent nature may not be sufficiently identified this classic approach. Here, study aims explore with nonstationary conditio...

This article aims to observe the microstructure, mechanical properties, and interface bonding of a 0.35Cr-1.9Ni-0.55Mo alloy deposited on 20Cr steel by wire arc-based directed energy deposition (WA-DED). For this purpose, different characterization techniques such as optical microscope, scanning electron microscopy (SEM) with dispersive spectroscopy (EDS), high-resolution X-ray diffractometer w...
