ParFlow Summer School 2020 / 2021 (cancelled)

ABC/J Summer School on modelling surface and subsurface flow on high-performance computers

ParFlow is a parallel, integrated hydrology model that simulates spatially distributed surface and subsurface flow, as well as land surface processes including evapotranspiration and snow. We are offering an Introductory and Advanced Short Course on ParFlow. The registration will be opened later this year.

ParFlow ( is a numerical model that simulates the hydrologic cycle from the bedrock to the top of the plant canopy. It integrates three-dimensional groundwater flow with overland flow and plant processes using physically-based equations to rigorously simulate fluxes of water and energy in complex real-world systems. ParFlow is a computationally advanced model that can run on laptops and supercomputers and has been used in hundreds of studies evaluating hydrologic processes from the hillslope to the continental scale. ParFlow is open source ( promoting community of active users and developers interested in advancing computational hydrology and improving hydrologic understanding.

Introduction to ParFlow

The trainee will learn about the basic theory of ParFlow, how to generate all necessary input information to construct basic ParFlow models, and perform simulations. In addition, post-processing and visualization of ParFlow results will be discussed.

Advanced applications

The trainee is familiar with ParFlow and will learn about advanced input functionality that is required to construct large-scale, sophisticated models to simulate terrestrial systems from the subsurface to the land surface. Simulations will be performed and the results will be discussed and analyzed in the context of high-performance computing, parallel scaling and big data analytics.

The course had to be cancelled this year.


Fees for participants from academia

Fees for participants from non-academia/industry

  • Introductory Course: 476 EUR, including 19% VAT
  • Advanced Course: 476 EUR, including 19% VAT

Payment details and further information will be given with the notifications. All participants need to cover their expenses for travel and accommodation by themselves. Catering during the event will be provided including coffee breaks, lunch breaks, and drinks.


A limited number of scholarships is available for both courses. Successful applicants will receive a waiver of the course fee for attending the introductory and/or advanced course. If you would like to apply for a scholarship, please give sufficient reasons for your need for support in the field 'letter of motivation' within the online registration form.
