    11New:
    22---
     3
     4Plant canopy model of Watanabe (2004,BLM 112,307-341) added.
     5It can be switched on by the inipar parameter plant_canopy.
     6The inipar parameter canopy_mode can be used to prescribe a
     7plant canopy type. The default case is a homogeneous plant
     8canopy. Heterogeneous distributions of the leaf area
     9density and the canopy drag coefficient can be defined in the
     10new routine user_init_plant_canopy (user_interface).
     11The inipar parameters lad_surface, lad_vertical_gradient and
     12lad_vertical_gradient_level can be used in order to
     13prescribe the vertical profile of leaf area density. The
     14inipar parameter drag_coefficient determines the canopy
     15drag coefficient.
     16Finally, the inipar parameter pch_index determines the
     17index of the upper boundary of the plant canopy. 
    318
    419Allow new case bc_uv_t = 'dirichlet_0' for channel flow.
