Numerical Study of Macropore Impact on Ponded Infiltration in Clay Soils

Soil and Water Research, 2006
The single-porosity and dual-permeability models in HYDRUS-1D (Šimůnek et al. 1998, 2003) were used to simulate variably-saturated water movement in clay soils with and without macropores.

Modelling soil water and nutrient dynamics under different irrigation techniques of onion production

Water Science
Irrigation remains important to meet the needs of the people by increasing agricultural productivity. However, its water productivity in developing countries is low due to inefficient irrigation water management.

Rainwater Harvesting Infiltration Exploration Using Hydrus-1D

, 2019
Rainwater harvesting is an emerging facet in the water supply portfolio for developing more drought-resistant cities in the arid-southwest, and bioswales are touted by some as a potential method to recharge aquifers.

Experimental and modelling investigations of tracer transport in variably saturated agricultural soil of Thailand: Column study

Sustainable Environment Research, 2016
Tracer (Bromide) movement through the unsaturated agricultural soil was investigated in soil columns. Two tracer column experiments, with a diameter of 7 cm and a depth of 25 cm, were vertically homogeneous packed with sandy loam and then carried out to ...

Depth-dependent predictive information in monitored soil moisture profiles: Contrasting roles of persistence, forcing, and HYDRUS-derived states

Agricultural Water Management
Process-based simulations, recent observations, and external forcing may contain overlapping information for soil-water estimation, making the incremental value of process-model states difficult to establish.

Using HYDRUS-1D for estimating evapotranspiration and soil water content of irrigated winter wheat under different water management in a semi-arid region of Morocco

, 2019
International audienceThe objective of this study is to evaluate the potential of the HYDRUS-1D model to estimate actual crop evapotranspiration (ETa) and soil moisture (theta) in the root zone (0-50 cm) over irrigated winter wheat under different water ...
