Version 2.2.x

(August 2011)

Bugfix Release v2.2.1

General

Bug fixes:

  • gravity transport for multiple grain classes
  • correction of wall friction in BASEplane
  • strong coupling of hydraulic / sediment
  • suspension inflow in 1D (use of dynamic diffusion coefficient)
  • topo restart in 1D (cross section was written in a wrong way)
  • sediment transport in 1D: armored layer was not used for single grain calculations
  • correction of CV-thickness due to armored layer
  • output of bed-fluxes for Matlab
  • inner weir in 2D: the weir crest was set too high in certain cases where the weir level was below the ground level
  • too small pickup-rate in 2D suspension corrected
  • exchange terms for suspension in 2D corrected for dry elements which were wet before

Small Features:

  • CFL numbers up to 2.0 allowed
  • new calibration factor dor dynamic turbulent diffusitiy in 2D suspension
  • new sink velocity type (after Zhang)
  • new calibration parameters in 1D suspension (pickup-factor, factor for reference concentration, factor for turbulent viscosity)
  • more comprehensive transport diagram in 1D
  • max. layer thickness to be exceeded before a new layer is created can now be defined by the user in 1D

Minor Release v2.2

General:

New Features:

  • External coupling implemented for data exchange with external programs over TCP/IP (experimental stage)

Subsystem BASEparse:

  • Input Tags for new features

Subsystem BASEchain:

New Features:

  • Account for grain abrasion due to mechanical stress after Sternberg

Bug fixes:

  • Bugfix in layer creation for sediment transport

Subsystem BASEplane

New Features:

  • Cycle step for quasi-steady bed-load and suspension transport to speed up morphological simulations
  • zhydrograph boundary improved. Ghost cell velocities can be set to zero (e.g. for lakes) or to the upstream cell velocity (e.g. for a stream).
  • Threshold value can be set in water surface output in case of dry conditions
  • External sources for bed-load and suspension moved to MORPHOLOGY-block
  • Upwind-factor for bed-load transport is assigned now for each material index
  • 64-bit linux version available for Ubuntu Natty (11.04)

Bug fixes:

  • Correction in water balance for partially saturated elements
  • Bugfix in dynamic-depth solver, partially wetted cells were not treated correctly
