Summary Also known as Model type Single Model part of larger framework Note on status model Date note status model Technical specs Supported platforms Unix, Linux, Mac OS, Windows Other platform Programming language Fortran77 Other program language Code optimized Single Processor Multiple processors implemented Nr of distributed processors Nr of shared processors Start year development 1991 Does model development still take place? No If above answer is no, provide end year model development 1991 Code development status When did you indicate the 'code development status'? Model availability As code Source code availability (Or provide future intension) Source web address Source csdms web address Program license type Other Program license type other -- Memory requirements <512Mb Typical run time Minutes In/Output Describe input parameters Timestep (sec.), Spacestep (m), Flow velocity at river mouth (m/s), Width and depth of river mouth (m), Bedload dumping rate (m/s), Concentration (gm/m3 of coarse and med silt, Concentration (gm/m3) of fine silt and clay) Input format ASCII Other input format Describe output parameters Vertically-integrated flow velocities and bed elevations as functions of time and two horizontal dimensions Output format ASCII Other output format 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 Other visualization software any software that can read ASCII data Process Describe processes represented by the model This driver program solves the equations describing horizontal velocities in a buoyant, turbulent, plane jet issuing in a normal direction from a coast into a large volume of still fluid. Sedimentation under the jet is modelled using a hemipelagic rain formulation, bedload dumping, and downslope diffusion due to slides, slumps and turbidity currents. Describe key physical parameters and equations The equations are from Albertson et al. (1950) and Syvitski et al. (1988).
