• Maintenance - Cleaned up the friction library
• New feature - Added bedform routines based on Soulsby (2005)

Version 4.1 Revision 10 (01/17/2013)

Modifications

• New feature - Least squares interpolation
• Maintenance - Moved structures code to separate files.
• Maintenance - Cleaned up wetting and drying subroutine.

1. Added parallelization to onecellwidechannels special wetting/drying case loop.
2. Moved distance to wall calculation to eddy viscosity module and added parallelization.
3. Added parallelization to flpond.

• Bug Fix - Revised deferred correction subroutines and fixed OpenMP race condition
• Maintenance - Changed code structure so that component variable definitions are in fortran modules in separate files named *_def.F90 (e.g. sed_def.F90), and component libraries are in separate files named *_lib.F90 (e.g. sed_lib.F90). Also separated source into folders so that is better organized.
• Change - Revised new block structures for boundary specification
• New feature - Added OpenMP parallelization to sediment avalanching subroutine
• New features - Added time step statistics to sediment transport
• Change - Moved water density from module to input in all friction subroutines.
• Change - Cell-face water depth is not calcuated from cell face water elevation, and bottom elevation instead of interpolating the water depth between cells. The new approach more efficient since the bed elevation only changes once per time step, and the water level gradients are calculated anyway.
• Bug fix - Fixed bug related to bed slope correction in Lund-CIRP and Soulsby-Van Rijn transport equations.
• Bug fix - Fixed bug relates to simplified log-law wall friction formulation
• Bug fix - Corrected if statement in iterative log-law wall friction formulation
