| HYDRUS Workshop (September 20, 2018) | ||||||
|
Overview
Reliable modeling of water flow and solute transport through the vadose zone is extremely important as the vadose zone recharges water resources such as groundwater and rivers, serves as a buffer and filter for contaminants, and supports agricultural activities. Numerical modeling is a key tool for analyzing complex physical, chemical, and biological processes in the vadose zone. The HYDRUS software that simulates numerically water and solute movement in soils has received increasing attention worldwide because of its flexibility and versatility. This workshop provides not only all current and future HYDRUS users but also researchers, practitioners, and students, in various disciplines who work on numerical analysis of flow and transport in porous media, opportunity to present and discuss their applications in research, management, and education. It also provides rare opportunity to discuss future modeling needs directly with HYDRUS developers.
The 6th international workshop will be held at the University of Tokyo on September 20, 2018. The workshop is organized by the Soil Physics Division of JSIDRE and Japanese Society of Soil Physics. Both oral and poster presentations (preferably in English) are welcome. A special issue on one of the international journals will allow presenters to publish their work as peer reviewed articles. Details will be announced later. The deadline for submitting an abstract (no more than 300 words) is August 24, 2018. When submitting, please include a title, the authors involved (underline the name of the person giving the presentation), and their affiliations. Feel free to forward this information to anyone who may be interested in the workshop. We hope to see you all in Tokyo soon!

Tentative schedule
9:00 - 16:00 Lectures/oral presentations, 16:00- Poster session and refreshment
Registration now closed
Registration fees
3,000 JPY (Registration includes: proceedings, coffee breaks, refreshments). The registration
fee for students and for those who will be taking the short course will be free. The instruction for payment will be sent to you from the organizer after registration is made.
Objectives
The course begins with a detailed conceptual and mathematical description of water flow and solute transport processes in the vadose zone, followed by a brief overview of the use of finite element techniques for solving the governing flow and transport equations. Special attention is given to the highly nonlinear nature of the governing flow equation.
"Hands-on" computer sessions will provide participants an opportunity to become familiar with the Windows-based RETC, STANMOD, HYDRUS-1D and HYDRUS (2D/3D) software packages. Emphasis will be on the preparation of input data for a variety of applications, including flow and transport in a vadose zone, subsurface drip irrigation, variably-saturated flow in a transect with a stream, and flow and transport to a tile drain. Calibration will be discussed and demonstrated by means of both one- and two-dimensional inverse problems.
Instructors
The course introduces a new generation of Windows-based numerical models for simulating water, heat and/or contaminant transport in variably-saturated porous media. These include the HYDRUS-1D and HYDRUS (2D/3D) codes for one- and two-dimensional simulations, respectively, the STANMOD code for evaluating solute transport in the subsurface using one- and multi-dimensional solutions of the advection-dispersion equation, the RETC code for evaluating the hydraulic properties of unsaturated media, and the Rosetta code for estimating the soil hydraulic properties (and their uncertainty) from soil texture and related data. HYDRUS-1D and HYDRUS (2D/3D) are supported by interactive graphics-based interfaces for data-preprocessing, generation of unstructured as well as structured finite element grid systems, and graphic presentation of the simulation results. Except for HYDRUS (2D/3D) , all software packages are in the public domain.
