Wind lidars reveal turbulence transport mechanism in the wake of a tree [PDF]

open access: yesAtmospheric Chemistry and Physics, 2022
Solitary trees are natural land surface elements found in almost all climates, yet their influence on the surrounding airflow is poorly known. Here we use state-of-the-art, laser-based, remote sensing instruments to study the turbulent wind field in the ...

Winter hydrometeorological extreme events modulated by large-scale atmospheric circulation in southern Ontario [PDF]

open access: yesEarth System Dynamics, 2020
Extreme events are widely studied across the world because of their major implications for many aspects of society and especially floods. These events are generally studied in terms of precipitation or temperature extreme indices that are often not ...

Destination choice modeling with spatially distributed constraints

open access: yesJournal of Transport and Land Use, 2023
Destination choice models are a key component of any transport and land-use model. Applications in agent-based models allow for destination choice on an individual level including personal variables, like trip purpose, or situational variables.

Instability Problems and Density-Driven Convection in Saturated Porous Media Linking to Hydrogeology: A Review

open access: yesFluids, 2023
Investigations of fluid instability and density-driven convection in soils and rocks are motivated by both natural phenomena giving rise to ecological problems, and human activities. Knowledge about the admixture transportation by underground fluid flows

Comparison of methodologies for flow prediction through teleconnection indices. Case study: Paute river basin

open access: yesRevista Tecnológica, 2023
The Paute river basin (southern Ecuador) suffers hydrological changes due to climate change and human activities. Hydrological changes cause extreme events and affect ecosystems, hydroelectric plants, and quality of life. It highlights the importance of

Quantum computing of fluid dynamics using the hydrodynamic Schrödinger equation

open access: yesPhysical Review Research, 2023
Simulating fluid dynamics on a quantum computer is intrinsically difficult due to the nonlinear and non-Hamiltonian nature of the Navier-Stokes equation (NSE).

Parsimonious statistical learning models for low-flow estimation [PDF]

open access: yesHydrology and Earth System Sciences, 2022
Statistical learning methods offer a promising approach for low-flow regionalization. We examine seven statistical learning models (Lasso, linear, and nonlinear-model-based boosting, sparse partial least squares, principal component regression, random ...

An Efficient GPU Implementation of a Coupled Overland-Sewer Hydraulic Model with Pollutant Transport

open access: yesHydrology, 2021
Numerical simulation of flows that consider interaction between overland and drainage networks has become a practical tool to prevent and mitigate flood situations in urban environments, especially when dealing with intense storm events, where the ...

Complex styles of phreatomagmatic explosions at Kīlauea Volcano, Hawaii, controlled by magma structure

open access: yesFrontiers in Earth Science, 2023
Explosive eruptions at basaltic volcanoes remain poorly understood. Kīlauea Volcano is a type locality for basaltic eruptions and is well-known for effusive activity.
