This paper shows an advanced application of the smoothed particle hydrodynamics (SPH) method to numerical modeling noncohesive sediment flushing aiming at setup a reliable engineering tool for prediction coupled water-sediment dynamics bottom artificial reservoir. Both liquid and granular materials are modeled as weakly compressible viscous fluids, whose motion results from solution continuity momentum equations discretized according standard SPH formulation. The effect two alternative...
In recent years, the number of offshore floating structures has been growing and is expected to continue growing. Due climate change, frequency severity extreme waves are increasing. Numerical models can be a strategic tool in reliable design optimization marine structures. However, numerical parameters tuned plays crucial role, as they could limit model's applicability reliability. Furthermore, there many challenges modelling wave-structure interaction. Among these challenges, simulation...
Build-up/wash-off models were originally developed for small-scale laboratory facilities with uniform properties. The effective translation of these to catchment scale necessitates the meticulous calibration model parameters. present study combines Mat-SWMM tool a genetic algorithm (GA) improve build-up and wash-off For this purpose, was modified equip it capacity provide comprehensive water quality analysis outcomes. Additionally, research also conducts comparative examination two distinct...

The Vajont disaster was caused in 1963 by a landslide of about 270 million cubic meters that fell into hydroelectric reservoir and generated wave 200 m high which overtopped the dam 1917 casualties. With aim assessing why real height underestimated, series two-dimensional experiments were performed at University Padua 1968 considering scale characteristic cross section basin near dam: pushed stored water moving plate over sliding surface maximum run-up along opposite mountain side measured...

Abstract Groundwater flow modeling is commonly used to calculate groundwater heads, estimate paths and travel times, provide insights into solute transport processes within an aquifer. However, the values of input parameters that drive models are often highly uncertain due subsurface heterogeneity geologic complexity in combination with lack measurements/unreliable measurements. This uncertainty affects accuracy reliability model outputs. Therefore, parameters’ must be quantified before...
