CSDMS 2026: Modeling Landscapes in Motion

At University of Minnesota, Minneapolis MN, May 19 -22^nd 2026

Registration

Registration & abstract submission will open early 2026

Introduction

The CSDMS 2026 Annual Meeting will be broad in scope, bringing together CSDMS members to present new scientific insights in the modeling of surface dynamics and the impact of time and process scales, new advances in cyber-infrastructure, examples on coupling models, how social and ecological models can inform management, and more. Also, this is the 4^th year that you can submit Electronic Publications (Epubs); Jupyter notebooks that contain e.g. a scientific hypotheses description, a numerical solution, and some findings that are investigated by numerical algorithms or model, see also: Form:Annualmeeting2026#Electronic_publications_(Epubs). We reserved time during one of the plenary sessions for presentations of Epubs, so don't hold back and submit your Epubs! The meeting will further include:

• State-of-the art keynote presentations in earth-surface dynamics
• Hands-on clinics related to community models, tools and approaches
• Transformative software products and approaches designed to be accessible, easy to use, and relevant
• Breakout sessions
• Poster and Epubs Sessions

Agenda

A draft agenda will be posted closer to date.

Landscape Evolution as a Surface-Subsurface Problem: From Headwaters to Orogens Decades of research have shown that storm runoff in many settings is primarily composed of pre-event groundwater. This groundwater is actively flowing, sometimes against topographic gradients, and in quantities substantial enough to alter the catchment water balance. Such effects have been observed across diverse lithologies and topographic settings, including mountainous environments that fluvial landscape evolution models often intend to capture. Yet to this day, most landscape evolution models represent runoff as a simple overland flow process. To explore the effects of groundwater flow on landscape evolution, we have developed coupled models in Landlab that represent both geomorphic change and surface-subsurface flow processes, in which runoff generated by a distributed hydrological model drives stream power fluvial erosion. We examine (1) hydrological function and topography in headwaters at geomorphic steady-state, and (2) transient dynamics at orogen-scale drainage divides, grounding our work in case studies and large-sample analyses. The results suggest that interactions between the surface and subsurface are often critical to understanding landscape evolution, and that long-term coevolution of hydrological and geomorphic processes may explain certain emergent hydrological traits of watersheds today.

Clinics

Introduction to Structure-from-Motion Photogrammetry for Mapping Landscapes This clinic will be a hands-on exercise in making quantitative 3D digital models and orthomosaics from a collection of photographs, focusing on small to medium landscape scenes (think beach ripples to a small dune system). We will provide some background theory and work through the steps of constructing and assessing the accuracy of the model using commercial software (Agisoft Metashape). Pitfalls and best practices will be explained. Students are invited to bring their own imagery (check with us for guidance on best practices for image collection) or we will provide some, and we might collect some prior to the classroom portion. Any laptop will work, but those with NVIDIA graphics cards will be faster.

River morphodynamic modelling across scales using BASEMENT software River morphodynamic processes shape the landscape and are relevant for their characteristics. The modelling of such processes allows for analyzing and predicting trajectories in landscape evolution. The BASEMENT software is a versatile tool for the numerical modelling of various river morphodynamic processes from catchment to reach scale. The available 1D and 2D models are based on the Saint-Venant-Exner equations for transient flow including bed and suspended load, i.e. transport of coarse and fine sediments. Implemented numerical schemes for solving the governing equations are best choice for alpine conditions and efficiency is employed by parallelization for multi-core CPU and GPU. The software has an intuitive user interface that simplifies the setting up of models and comes along with comprehensive documentation. BASEMENT is available for free and is in transition to open source software. </br>The clinic includes a short introduction to the theoretical background of the models and demonstrates how to setup hydro and morphodynamic simulations that can be run straight away. For the case of the 1D model, a local river widening is considered where all states of gradually varied flow including flow transition may occur during bed level evolution until the situation reaches its dynamic equilibrium state. The case study follows a conceptual approach following best practice in application to ensure robust model setup and to avoid pitfalls.

Fora.ai: Embedding earth systems modeling in a collaborative framework for innovative, impactful and resilient solution-building Fora.ai is an intuitive digital environment that enables groups with diverse expertise to collaboratively interact with embedded simulation models to understand real world socio-environmental problems and create novel and impactful solutions. Participants interact with this digital representation and with each other, iteratively creating, revising and testing solutions until diverse needs are addressed. Workshop participants will use Fora.ai’s interactive game-board to collectively build solutions to environmental hazards (e.g., flooding and wildfires). The virtual environment allows for participation in a facilitated process in which users: 1) input their individual priorities, 2) collaboratively run simulations to understand the complexity of the hazards, 3) co-design solutions to address these problems, 4) see how their solutions affect outputs of interest, and 5) deliberate on the tradeoffs that arise from each solution due to competing priorities. Participants will be introduced to the environmental hazard model and, with facilitator assistance, engage in multiple iterations of the process of prioritization, solution-building, and reflection on results. This process will allow them to refine their proposed solutions towards intervention strategies that they would jointly support for implementation, with an understanding of its benefits and drawbacks. The workshop will end with a focus group debrief. Laptops or tablets required.

• Submitted abstracts

Conference Venue

This year the conference will be held at XXX at the University of Minnesota, Minneapolis, Minnesota.

Address:
University of Minnesota
XXX Building
XXX Street

Conference Lodging and Daily shuttles

For participants not receiving CSDMS travel support, CSDMS has secured a discounted lodging rate at the Residence Inn, Boulder Canyon. You will receive an emailed link for the discounted lodging upon completion of your meeting registration.

Daily shuttle service between the Boulder Marriott Canyon / Residence Inn Canyon and the meeting venue will depart the hotel each morning at 8:00 and 8:30AM and return to the hotel after the meeting each evening.

Poster guidelines

The poster boards are configured for up to 46" wide by 60" tall (portrait orientation) posters (116 cm wide by 152 cm tall). Anything larger than these dimensions will reduce the space of your colleagues so please be respectfull of these poster dimensions.

Electronic publications (Epubs)

We're excited to announce that we will also offer Epub submissions for this year's annual meeting. Epubs are Jupyter notebooks that contain a scientific problem description and some findings that are investigated by numerical algorithms or models, that walks the reader through the science by executing the algorithms or models. The Epubs will be reviewed and can be part of a poster or oral presentation or separately submitted. Guidelines on what the notebook should include can be found here.
