Hydrus-1D Projects - Infiltration
- Project Group: Infiltration
- Description: Examples demonstrating the use of HYDRUS-1D to simulate infiltration from ponding and rainfall and issues associated with this process. The text (and projects) that can be downloaded below has been originally written for the manuscript of Vereecken et al. (in review in VZJ). However, since the text has not eventually been used in the final version of this manuscript, we have decided to share it, as well as all examples carried out for this manuscript, with the HYDRUS users on the HYDRUS website.

Fig. 2
|
Flux infiltration. The effect of soil texture (12 USDA textural classes) on the time to ponding and actual infiltration rates.
|
|
Fig. 3
|
Flux infiltration. The effect of the initial saturation on the time to ponding and actual infiltration rates (for sandy loam).
|
|
Fig. 4
|
Flux infiltration. The effect of the spatial discretization on the time to ponding and actual infiltration rates (for sandy loam and clay loam).
|
|
Fig. 5
|
Flux infiltration. The effect of three ponding scenarios (no, unlimited, and limited surface ponding) for infiltration from a high-intensity rainfall event in a sandy loam soil on the surface pressure heads.

Fig. 6
|
Flux infiltration. The effect of three ponding scenarios (no, unlimited, and limited surface ponding) for infiltration from a high-intensity rainfall event in a sandy loam soil on actual and cumulative water fluxes (rainfall, infiltration, and surface runoff).

Fig. 7
|
Flux infiltration. The effect of the duration of the 10-cm rainfall event (with the same rainfall height) on actual and cumulative infiltration into loam.
