A general description of the mathematical and numerical formulations used in modern reactive transport codes relevant for subsurface environmental simulations is presented. The are followed by short descriptions commonly available simulators that consider continuum representations flow, transport, reactions porous media. These applicable to most benchmark problems included this special issue. list described briefly here includes PHREEQC, HPx, PHT3D, OpenGeoSys (OGS), HYTEC, ORCHESTRA,...
Core Ideas A community effort is needed to move soil modeling forward. Establishing an international consortium key in this respect. There a need better integrate existing knowledge models. Integration of data and models challenge modeling. The remarkable complexity its importance wide range ecosystem services presents major challenges the processes. Although progress has occurred last decades, processes remain disjointed between disciplines or services, with considerable uncertainty...
Key Points Efficient two‐stage MCMC simulation for CPU‐demanding sampling Real‐world application to the inference of a multi‐layered 3D aquifer model A 2‐5 times observed speed up in efficiency
Abstract The HYDRUS codes have become standard tools for addressing many soil, agricultural, environmental, and hydrological problems requiring the evaluation of various subsurface physical, chemical, biological processes. There are now thousands users worldwide, with applications models appearing in peer‐reviewed literature. In this manuscript, we provide an overview capabilities most recent Version 5 HYDRUS, focusing primarily on features implemented since 2016. We briefly describe model...
Probabilistic inversion within a multiple-point statistics framework is often computationally prohibitive for high-dimensional problems. To partly address this, we introduce and evaluate new training-image based approach complex geologic media. Our relies on deep neural network of the generative adversarial (GAN) type. After training using image (TI), our proposed spatial GAN (SGAN) can quickly generate 2D 3D unconditional realizations. A key characteristic SGAN that it defines (very)...
Abstract. In this paper, we present and analyze a novel global database of soil infiltration measurements, the Soil Water Infiltration Global (SWIG) database. total, 5023 curves were collected across all continents in SWIG These data either provided quality checked by scientists who performed experiments or they digitized from published articles. Data 54 different countries included with major contributions Iran, China, USA. addition to its extensive geographical coverage, cover research...
Unsaturated hydraulic properties of field soils are needed for water flow and solute transport calculations in variably saturated soils. The purpose this study was to quantify the spatial variability crosscorrelation estimated parameter values a flexible retention model that fitted measured data. Moisture characteristic (MRC) curves were on 100-cm3 undisturbed soil cores collected at 180 locations along 31-m-long transect three-layered profile depths 0.1, 0.5, 0.9 m. Sampling intervals...
Calibration of variably saturated flow models with field monitoring data is complicated by the strongly nonlinear dependency unsaturated parameters on water content. Combining predictions using various independent models, often called multimodel prediction , becoming a popular modeling technique. The objective this study was to compare different methods simulation soil regime pedotransfer functions (PTFs). We solved Richards equation HYDRUS‐1D parameter sets derived from 19 published PTFs...
Abstract Data science (digitalisation and artificial intelligence) became more than an important facilitator for many domains in fundamental applied sciences as well industry is disrupting the way of research already to a large extent. Originally, data were viewed be well-suited, especially, data-intensive applications such image processing, pattern recognition, etc. In recent past, particularly, data-driven physics-inspired machine learning methods have been developed extent that they...
When a field or small watershed is repeatedly surveyed for soil water content, sites often can be spotted where consistently wetter dryer than average across the study area. The phenomenon has been called time stability, temporal persistence in spatial patterns of contents. Relatively less known about content at various depths. objectives this work are to demonstrate contents measured on vertical two‐dimensional grid, and propose technique use remedy effect probe malfunctioning estimates...
