|5 years 10 months ||Finally, the 5 expositions test works properly and has a sane
structure. The necessary build code has been added for CAAMLIO.

|5 years 10 months ||A documentation warning has been fixed. The examples have been
cleaned-up (removing commented out lines). The res1exp and
massbalance test now properly work and don't use multiple copies of
the same files.
|5 years 10 months ||The implementation of E. Schmucki's albedo parameterization needed
refinements. Now a version using the classical grain size and one
using the optical equivalent grain size are implemented.

Equation for snow:
- theta_r was not exactly determined as described in the paper in

|5 years 10 months ||Change to soil freezing/thawing for Richards equation. Temperature
change of soil due to phase changes is stored in a temporary

*.inp files with only one radiation flux are rarely found today.
|5 years 10 months ||This is now a hopefully well tested commit that finalizes the
introduction of a SNOW_EROSION switch acting only on the main
station and SNOW_REDISTRIBUTION acting on virtual slopes only.

|5 years 10 months ||Switching to DGESVD solver when DGTSV fails is not always preferred,
as DGESVD can be so slow, that a smaller time step and trying DGTSV
again works faster. This is especially the case in simulations with
many layers. Now this can be controlled with

water transport in snow using Richards equation. Just taking
theta_r=0 was causing a too big error in wet snow covers, so
something different was needed.
