= ORCHIDEE-LAK =
ORCHIDEE-LAK is based on the version 4369 of the trunk.
ORCHIDEE-LAK is the same as ORCHIDEE-MEB except that at the column 2, is assigned the energy and hydrology budgets of
the lake.

== Implementation ==

In this version, the multicolumn-version has been developed based on the same idea of the implementation in
ORCHIDEE-DOFOCCO-MULTICOLUMN.
This implementation is done in ORCHIDEE-MEB.

For calling the lake, the column 2 has been assigned.
In the module lake.f90, the implementation of the surface temperature, different fluxes of the lake are done.
The module lake.f90 is an adaptation of FLake (http://www.flake.igb-berlin.de/docs.shtml) to ORCHIDEE.



== Validation of the code ==
Comparison between the surface temperature of this version with FLake offline by using the same inputs.
i.e. data from the Seine basins.

== Future of the version ==



== Run this version ==
In order to run the version, as well as for the version ORCHIDEE-MEB,
compile it via gmake without_xios then execute it in a test case
where a run.def file with the different parameters for the lake version are
defined.
The different parameters to assign a value are:


{{{
#Depth of the lake
DEPTH_LAKE=20 
#Extinction coefficient
TURBIDITY_LAKE=0.1
FETCH=4000
#Height at which is measured the air temperature
HEIGHT_TQ=2
#Height at which is measured the wind speed
HEIGHT_U=2
#Initial mean temperature
T_m=10
#Initial mixed-layer temperature
T_wML=10
#Initial ice temperature
T_ICE=0
#Initial bottom temperature
T_bot=10
#Height of the thermocline
h_ML=10
#Thickness of the ice layer
h_ice=0
#Shape coefficient
CTT=0.5
#Height and temperature of the bottom sediment layer
H_B1=0
T_B1=4
#Time step 
dtlake=1800
