Solving the Richards infiltration equation by coupling physics-informed neural networks with Hydrus-1D. [PDF]

Sci Rep
Abstract The movement and infiltration of groundwater play a crucial role in environmental engineering and water resource management. The Richards equation, a fundamental model describing water transport in unsaturated soils, encounters significant challenges in traditional numerical solutions due to its strong nonlinearity, complex boundary ...

Modeling Soil Profile Salinity with HYDRUS-1D

Selcuk Journal of Agricultural and Food Sciences, 2022
Salt accumulation within the root zone significantly effects plant growth and development in arid and semi-arid regions. Today, use of low-quality irrigation water in agricultural production is increasing rapidly, because of continuous depletion and pollution of water resources. This means more salt transferred to the soil profile.

Previously Unrecognized Land-Use Control on Deep Soil CO₂ Sink. [PDF]

Glob Chang Biol
Transport‐limited, boundary‐conditioned bidirectional exchange of topsoil‐respired CO2 drives CO2 accumulation in less bioactive subsoils in concentrations that cannot be explained by in situ production alone and far exceed atmospheric boundary concentrations, revealing a production‐transport imbalance and a potential land‐use‐sensitive pathway for ...

Whole orchard recycling in California's Central Valley: Benefits, management, and adoption. [PDF]

J Environ Qual
Abstract Whole orchard recycling (WOR) has become a common practice in California (CA) orchards and vineyards due to declining options for agricultural biomass disposal. WOR is the process by which entire orchards or vineyards are shredded into chips, spread onto the soil surface, and incorporated into the soil before replanting a new crop.

Sensitivity of groundwater recharge using climatic analogues and HYDRUS-1D [PDF]

Hydrology and Earth System Sciences, 2012
Abstract. The sensitivity of groundwater recharge to different climate conditions was simulated using the approach of climatic analogue stations, i.e. stations presently experiencing climatic conditions corresponding to a possible future climate state.

Dataset for: Physics-informed neural networks with monotonicity constraints for Richardson-Richards equation: Estimation of constitutive relationships and soil water flux density from volumetric water content measurements by Toshiyuki Bandai and Teamrat A. Ghezzehei

, 2022
Simulation of soil moisture dynamics is important for various fields, such as agriculture, hydrological modeling, and natural disasters. Such simulations are conducted by solving a partial differential equation (PDE) called the Richardson-Richards ...

Simulation of Fluoride Transport in a Calcareous Soil Using HYDRUS-1D [PDF]

Journal of Water and Soil Science, 2015
Transport of fluoride and consumption of groundwater with excess fluoride concentrations poses a health threat to millions of people around the world. The objective of this study was to simulate transport of fluoride (F) using HYDRUS-1D model. The study was conducted in lysimeters at Lavark research station site in Isfahan.

Adapting HYDRUS-1D to simulate the transport of soil water isotopes with evaporation fractionation

Environmental Modelling & Software, 2021
Abstract Ecohydrological processes are often evaluated by studying the fate of stable water isotopes. However, isotopic fractionation during evaporation is often ignored or simplified in current models, resulting in simulation errors that may be propagated into practical applications of stable isotope tracing. In this study, we adapted and tested the

Leachate production estimation for a landfill in south of Brazil using Hydrus-1D [PDF]

E3S Web of Conferences, 2020
The disposal of municipal solid waste (MSW) is currently a great challenge to society mainly due to the threat posed by leachate and gases released from the decomposition sites. Landfills have been widely used for this purpose because their waterproofing, drainage and treatment systems have reduced the risks of soil, water and air contamination ...
