RISAn Enhanced Gray Wolf Optimizer and Its Application to Parameter Calibration in Open-Channel Flow
Publisher: American Society of Civil Engineers
Abstract: AbstractParameter calibration is a key issue in open-channel flow models. Manning’s roughness
coefficient, a comprehensive indicator of flow resistance, is highly variable and
location-dependent. An optimization objective ...
Drought Characteristics and Propagation in the Semiarid Heihe River Basin in Northwestern China
Publisher: American Meteorological Society
Abstract: Meteorological and hydrological droughts can bring different socioeconomic impacts. In this study, we investigated meteorological and hydrological drought characteristics and propagation using the standardized precipitation ...
Rheological and Micro Properties of High-Viscosity Binder–Incorporated Polyphosphoric Acid and Rock Asphalt
Publisher: American Society of Civil Engineers
Abstract: AbstractTo enhance the performance of high-viscosity modified asphalt (HVMA), polyphosphoric
acid (PPA) and North American rock asphalt (NA–RA) were incorporated into styrene-butadiene-styrene
(SBS)/crumb rubber (CR) ...
Effects of Tetradecane Direct Incorporation on Asphalt Properties: A Molecular Dynamics and Experimental Approach
Publisher: American Society of Civil Engineers
Abstract: AbstractTetradecane (TD), a low-temperature phase change material, can compromise the performance
of asphalt binder upon leakage. To investigate the macro- and nanoscale mechanisms
of TD-induced damage, this study combined ...
