Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Model type Modular Model part of larger framework Note on status model Date note status model Incorporated models or components: WBM-WTM, BQART, Spatial dimensions 2D Spatial extent Global, Continental Model domain One-line model description Global sediment flux and water discharge model. Extended model description An extension of the WBMplus (WBM/WTM) model. Introduce a riverine sediment flux component based on the BQART and Psi models.

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 GPL v2 Program license type other Memory requirements 9 GB for global simulation at 6 arc-min resolution Typical run time 3 hours per year for global simulation at 6 arc-min resolution Describe input parameters depending on configuration, the model can be run with Air temperature and Precipitation only. In the most complex configuration, the model will also need vapor pressure, solar radiation, wind, daily minimum and maximum temperature. Built-in functions allow trading input variables (e.g. use cloud cover instead of solar radiation). Input format Binary Other input format RGIS - .gdbc Describe output parameters The WBMplus model can output any variables used for the water balance and transport calculations. WBMsed unique output are: sediment-flux, over-bank water discharge, and all the BQART parameters. Output format Binary Other output format RGIS - .gdbc and conversion to NetCDF Pre-processing software needed? No Describe pre-processing software Post-processing software needed? No Describe post-processing software Visualization software needed? Yes If above answer is yes ESRI Other visualization software VisIt Describe processes represented by the model see: Sagy Cohen, Albert J. Kettner, James P.M. Syvitski, Balazs M.

Describe key physical parameters and equations [[Describe key physical parameters::The BQART equation: Qs=ϖBQ¯0.31A0.5RT for T⩾2∘C Qs=2ϖBQ¯0.31A0.5R for T<2∘C Qs - aver. sediment flux (kg/s) ϖ - coefficient of proportionality (kg s−1 km−2 °C−1) (=0.02) B - =L(1−Te) Eh, Te is the trapping efficiency of a reservoir or lake, L is lithology and Eh is human erosivity factor. Q - avr. water discharge (m3/s) - [calculated by a WBMplus module] A - basin area (km) R - max. relief (km) T - avr. temperature]] Describe length scale and resolution constraints Available datasets are for global and continental domains. Realistic high-res simulations for global scale is 6 arc-min and for continental 3 arc-min. Higher resolution datasets are available for both (e.g. 15 arc-sec for Europe). Describe time scale and resolution constraints It simulate at daily time-steps. Maximum available datasets time-span is between 1901-present. Describe any numerical limitations and issues Describe available calibration data sets Upload calibration data sets if available: Describe available test data sets Extensive input dataset is available on the CSDMS HPCC (beach) at '/scratch/ccny/RGISarchive' and '/scratch/saco2635/RGISarchiveCSDMS'. Upload test data sets if available: Describe ideal data for testing Do you have current or future plans for collaborating with other researchers? Is there a manual available? Yes Upload manual if available: Media:WBMsed manual2-lmf.doc, Media:WBMsed.v2 manual.pdf Model website if any Model forum / discussion board Model version 2 is available. Comments This part will be filled out by CSDMS staff OpenMI compliant No but possible BMI compliant No but possible WMT component No not possible PyMT component Is this a data component Can be coupled with:
