7th International Conference 'Hydrus Software Applications to Subsurface Flow and Contaminant Transport Problems'
See also information about the HYDRUS course held earlier the same week.
Detailed Information
Aims and Scope
The conference Hydrus Software Applications to Subsurface Flow and Contaminant Transport Problems will focus on applications of advanced numerical models simulating variably saturated flow, heat transport, and transport of various contaminants (nutrients, pollutants, pathogenic microorganisms) in soils and groundwater. Similarly, as the very successful earlier workshops in this series (Utrecht in 2006, Tokyo in 2008, and Prague in 2008, 2013, and 2017) the 7th conference will bring together world-leading and junior scientists and engineers from different branches of the soil, hydrologic, and environmental communities.
The conference is not limited to applications involving the use of HYDRUS and its modules. Applications of other numerical tools (e.g., Tough2, SWAP, MACRO) are encouraged and welcomed also.
We will introduce a new Version 5 of HYDRUS resulting from merging HYDRUS-1D with HYDRUS (2D/3D), implementing the newly integrated form of coupling PHREEQC with HYDRUS (HPx), and including new modules such as PFAS, Particle Tracking, Dynamic Plant Uptake, Cosmic, etc.
Topics
The main topics at the conference include (but are not limited to):
- Variably-Saturated Water Flow
Modeling of various agricultural, hydrologic, and environmental problems at different scales, including preferential/nonequilibrium flow - Heat Transport
Modeling the transport of energy, including vapor flow, and issues related to freezing/thawing - Transport of Contaminants and Particle-Like Substances
Transport of pollutants, colloids, viruses, bacteria, and nanoparticles. Colloid-facilitated solute transport - Biogeochemical Transport and Reactions
Applications of the HYDRUS modules HP1/2/3, UnsatChem, and Wetlands, as well as other models with similar capabilities. - Inverse Problems
Inverse modeling and parameter estimation using different optimization tools (e.g., Marquardt, AMALGAM, DREAM)

Call for Abstracts and Manuscripts
Authors are invited to submit a one-page abstract for oral or poster presentation by email (to Jiri.Simunek@ucr.edu) by March 15, 2023. Please underline the name of the presenting author, specify the topic, and indicate preference for presentation (oral or poster). Authors will be notified of acceptance of the reviewed abstracts before March 31, 2023.
Abstracts: Abstract submission deadline - March 15, 2023. If you still want to submit an abstract (after a deadline), contact us first.
Posters: The format of the panels on which posters will be displayed is width × height, 71 x 97 cm.
A book of abstracts will be distributed to the participants at the beginning of the workshop.
Registration info
Registration fees:
- Early registration (reduced registration fees, before March 15, 2023): 350 EUR (200 EUR when also registering for the short course at full undiscounted price)
- Late registration (standard registration fees, after March 15 and before April 15 2023): 400 EUR (250 EUR when also registering for the short course at full undiscounted price)
- Student early registration (before March 15, 2023): 200 EUR (100 EUR when also registering for the short course).
- Student late registration (after March 15 and before April 15, 2023): 250 EUR (200 EUR when also registering for the short course).
- A discount of 100 Euro for an online option of the conference is also available. However, we strongly recommend the “on-site” type registration, allowing attendees to actively participate in the course and conference. On-site participation will allow attendees to interact with other participants and the HYDRUS developers, potentially obtaining their input on one’s own work and research, and establishing working contacts and mutual collaborations. The on-line option is intended mainly for passive following of the course and conference activities (on-line presentations at the conference will not be allowed).
