CSDMS =Community Surface Dynamics Modeling System

Promotes development and use of numerical modeling in earth surface dynamics research.

~ 450 members, (int.)nationally, academic, industry, government

• Model, Data and Educational Repositories• Access to supercomputer system, called Beach• Development of an easy-to-use Coupling Tool (CMT)

What is CSDMS?

CSDMS Repositories

o Data Repository

o Model Repository

o Educational Repository

Model Repository

• Models have meta-data

• Models are open-source

• Models are freely downloadable from CSDMS HPCC

Model Repository

We developed a database for the Model Repository, now users:1.Provide Metadata in new user-friendly questionnaire.2.Submit Model and Associated Test & Validation files to CSDMS

Three classes of Models

TOPOFLOW

Sept 2010,

93 terrestrial models,57 Coastal models,27 Marine models,50 Hydrology models,4 Carbonate models.

Objective: distribute model simulations, educational presentations, reports, publications, short course material.

EKT Repository in 2010:

- 3 modeling textbooks + all codes available through repository.

- 4 modeling courses; more general to detailed processes.

- 20 modeling labs; coastal-geological, terrestrial and sediment transport.

- > 40 educational movies (real-world and model animations)

Educational Repository

Lectures & Labs on Wiki

http://csdms.colorado.edu/wiki/Education_portal

Educational Animations

o Model animations to explain surface-dynamics processes. Every animation has a short description, and explanation of theory, and references.o Fit into the data-base structure in Wiki.

CEM: Coastal Evolution of Wave-dominated Coast (Ashton & Murray).

Educational Animations

Basic model experiments, stepping up in complexity.Associated theory and algorithms are key for learning processes as well as model sensitivity.

SEDFLUX: Basic Plume SEDFLUX: High Switch Frequency

CMT Tool

The CSDMS Modeling Tool allows you to couple and run CSDMS components on the CSDMS supercomputer in a user-friendly environment.

A component can be any unit that encapsulates some useful functionality, most often a model or function.

CMT Tool

CMT Tool• Input data needs to be prepared;

standardizing formats (NetCDF)

• Output data can be processed with VisIT,

• Lab 2 dedicated to NetCDFand VisIT

Temperature, depth volume

Coupled Models

Ability to drag in components; run them together

4 course labs will be dedicated to running models

Modeling Project

• Discuss and propose modeling projects

• 2 Labs for running simulations and presentations

• Report + documented simulations graded
