Yes If above answer is no, provide end year model development Code development status When did you indicate the 'code development status'? Model availability As code Source code availability (Or provide future intension) Through CSDMS repository Source web address Source csdms web address Program license type Other Program license type other -- Memory requirements High Typical run time hours Describe input parameters Simulation time (t) and time step (dt), Initial grid size and slope, Incoming discharge and sediment load (t), Sea level (t), no of grain size classes, grain size distribution, grain size. Sediment transport coeficients Input format ASCII Other input format Describe output parameters Grid of deposition of different grains over time. The model generates postscript files of stratigraphic sections. Output format ASCII Other output format Pre-processing software needed? No Describe pre-processing software Post-processing software needed? Yes Describe post-processing software Grid plotting software, Postscript plotting software Visualization software needed? Yes If above answer is yes Matlab Other visualization software SURFER/GRAPHER Describe processes represented by the model Fluvial erosion and depositions, lateral deposition across the floodplain, plume deposition in marine domain. Describe key physical parameters and equations See references. Describe length scale and resolution constraints The model domain starts in the fluvial floodplain, the main river channel is considered an incoming boundary condition. Gridcells are typically averaged over 100's meters to 1000's of meters. Tests ran with grids of 150 by 150 km. Describe time scale and resolution constraints Developed as a stratigraphic model, approach is event-based. Intended time scale ranges from several decades to Holocene (10-10.000yrs). Describe any numerical limitations and issues Code is research grade Describe available calibration data sets Not readily available; theoretical experiments are available as examples. Upload calibration data sets if available: Describe available test data sets AquaTellUs was originally developed for simulation of the fluvial-dominated Volga delta. The 2D experiments are still available and can be used as a test data set. Upload test data sets if available: Describe ideal data for testing Boundary conditions like river discharge and sediment loads, input grainsize data, sea level history. Floodplain and deltaic sedimentation rates and grainsize data. Do you have current or future plans for collaborating with other researchers? Intent to use for braided Arctic fan deltas. CSDMS group is currently working on floodplain processes and bedload distribution patterns based on RS data. Is there a manual available? No Upload manual if available: Model website if any Model forum / discussion board Comments Code is research grade and needs to be refractored before submission to CSDMS. This part will be filled out by CSDMS staff OpenMI compliant No but possible BMI compliant No but possible WMT component In progress PyMT component Is this a data component Can be coupled with:
