F28: A novel coupling strategy for 1D/2D hydraulic models for flood risk assessment of the Mekong Delta

open access: yesJournal of Hydroinformatics, 2023
Coupling models of different dimensions is one of the most important yet under-represented challenges. This paper introduces a new modeling strategy to streamline a more flexible and effective integrated one-dimensional (1D)/two-dimensional (2D) model ...

Using multi-event hydrologic and hydraulic signatures from water level sensors to diagnose locations of uncertainty in integrated urban drainage models used in living digital twins

open access: yesWater Science and Technology, 2022
Digital twins of urban drainage systems require simulation models that can adequately replicate the physical system. All models have their limitations, and it is important to investigate when and where simulation results are acceptable and to communicate

On a Continuum Model for Avalanche Flow and Its Simplified Variants

open access: yesGeosciences, 2020
Mathematical models of different degrees of complexity, describing the motion of a snow avalanche along a path with given center line and spatially varying width, are formulated and compared.

Seasonal and Interannual Variations in China’s Groundwater Based on GRACE Data and Multisource Hydrological Models

open access: yesRemote Sensing, 2020
In this study, we used in situ measurements for the first time to analyze the applicability and effectiveness of evaluating groundwater storage (GWS) changes across China using Gravity Recovery and Climate Experiment (GRACE) satellite products and ...

Stem hydraulic capacitance decreases with drought stress : implications for modelling tree hydraulics in the Mediterranean oak Quercus ilex [PDF]

open access: yes, 2017
Hydraulic modelling is a primary tool to predict plant performance in future drier scenarios. However, as most tree models are validated under non-stress conditions they may fail when water becomes limiting.

Beam model for hydraulic fracturing [PDF]

open access: yesPhysical Review B, 1994
We investigate numerically the shape of cracks obtained in hydraulic fracturing at constant pressure using a square-lattice beam model with disorder. We consider the case in which only beams under tension can break, and discuss the conditions under which the resulting cracks may develop fractal patterns.

Mathematical Hydraulic Models of One-Dimensional Unsteady Flow in Rivers [PDF]

open access: yes, 2018
This flow in rivers is concerned with unsteady flow in open channel and it mathematically governed by the Saint Venant equation, using a four-point implicit finite difference scheme.

Uncertainty in the determination of soil hydraulic parameters and its influence on the performance of two hydrological models of different complexity [PDF]

open access: yes, 2009
Data of soil hydraulic properties forms often a limiting factor in unsaturated zone modelling, especially at the larger scales. Investigations for the hydraulic characterization of soils are time-consuming and costly, and the accuracy of the results ...

Predicting Hydraulic Jump Length on Rough Beds Using Data-Driven Models [PDF]

open access: yesJournal of Rehabilitation in Civil Engineering, 2018
The hydraulic jump can be used for some purpose such as dissipating the flow energy in order to prevent bed erosion; aerating water and facilitating the mixing procedure of chemical that used for water purification.
