Version 2.7.x
(February 2017)
Minor Release v2.7
General
New Features
- New bedload transport formulae: Wilcock and Crowe, Engelund and Hansen
(for single-grain) - Definition of external sediment and hydraulic source over material index
- Improved and extended mpm_multi and smartjaeggi_multi using hiding function
according to Ashida and Michiue (1972) with new options to choose reference
critical Shields parameter: based on mean, median, geometric diameter, or
diameter of fractions - New logarithmic friction laws: Yalin, Bezzola
Bugfixes
- User-defined settling velocities
- New tag bedload_exponent used for mpm and mpm_multi, correction of Wong
and Parker formulation - dynamic_depth_solver_precision: eliminated dependency on min_water_depth
- Minor others
Subsystem BASEparse
Subsystem BASEchain
Subsystem BASEplane
New Features
- New local_slope_correction concept: local_slope_longitudinal and
local_slope_lateral suppressed, introduced local_slope_vanrijn and
local_slope_chen - New tag theta_critical_default with theta_critical_vanrijn and theta_critical_yalin
- Dynamic determination of flow curvature based on water surface inclination
- Dynamic determination of flow curvature based on local streamline
reconstruction - Hydraulic boundary hydrograph with dynamic slope in case of erosion
- New element output momentum that returns flow intensity (water depth times
velocity)
Bug-fixes
- Local slope: updating local slope correction due to changed bed slope
- Correction of zero_gradient downstream boundary condition
- Revision of upwinding in bed load transport (bed load flux averaging)
- Write sediment_grid.shp file to the right location (where .bmc file and result
files are written) - Revision and new concept for creation and initialization of layers
(create_new_layers) - Improved node_history output for grain_size
- control_volume_type: replaced dmean by d90
- Fix grain_size_friction on fixed bed
- Fix high velocities in upstream BCs for inner weir, inner gate and inner h-q
