Estimating hydraulic parameters for the complex hydrodynamic models [PDF]

open access: yesMining and Metallurgy Engineering Bor, 2017
Hydrodynamic models have usually been calibrated manually, by trial-and-error, with different values of hydraulic parameters and hydraulic characteristics of boundary conditions.

Towards the construction of representative regional hydro(geo)logical numerical models: Modelling the upper Danube basin as a starting point

open access: yesFrontiers in Earth Science, 2023
Introduction: Pressure on groundwater resources is increasing rapidly by population growth and climate change effects. Thus, it is urgent to quantify their availability and determine their dynamics at a global scale to assess the impacts of climate ...

Non-Gaussian parameter inference for hydrogeological models using Stein Variational Gradient Descent [PDF]

open access: yesWater Resources Research, 2020
AbstractThe sustainable management of groundwater demands a faithful characterization of the subsurface. This, in turn, requires information which is generally not readily available. To bridge the gap between data need and availability, numerical models are often used to synthesize plausible scenarios not only from direct information but also from ...
