    200200Topography mode.\\\\
    201201The user can choose between the following modes:\\\\
    202 '' 'flat' ''\\\\
    203   Flat surface.\\\\
    204 '' 'single_building' ''\\\\
     202'' 'flat' ''
     203  Flat surface.
     204'' 'single_building' ''
    205205  Flow around a single rectangular building mounted on a flat surface.
    206   The building size and location can be specified by the parameters building_height, building_length_x, building_length_y, building_wall_left and    building_wall_south.
    207 
    208 'single_street_canyon'
    209 Flow over a single, quasi-2D street canyon of infinite length oriented either in x- or in y-direction.
    210 The canyon size, orientation and location can be specified by the parameters canyon_height plus either canyon_width_x and canyon_wall_left or  canyon_width_y and canyon_wall_south.
    211  
    212 
    213 'read_from_file'
    214 Flow around arbitrary topography.
    215 This mode requires the input file TOPOGRAPHY_DATA. This file contains the arbitrary topography height information in m. These data must exactly match the horizontal grid.
    216 
    217 Alternatively, the user may add code to the user interface subroutine user_init_grid to allow further topography modes. These require to explicitly set the topography_grid_convention to either 'cell_edge' or 'cell_center'.
    218 
    219 Non-flat topography modes may assign a kinematic sensible wall_heatflux and a kinematic wall_humidityflux (requires humidity = .T.) or a wall_scalarflux (requires passive_scalar = .T.) at the five topography faces.
    220 
    221 All non-flat topography modes require the use of momentum_advec = scalar_advec = 'pw-scheme', psolver /= 'sor',  alpha_surface = 0.0, galilei_transformation = .F., cloud_physics  = .F.,  cloud_droplets = .F., and prandtl_layer = .T..
    222 
    223 Note that an inclined model domain requires the use of topography = 'flat' and a nonzero alpha_surface.
     206  The building size and location can be specified by the parameters [#building_height building_height], [#building_length_x building_length_x], [#building_length_y building_length_y], [#building_wall_left building_wall_left] and [#building_wall_south building_wall_south].
     207'' 'single_street_canyon' ''
     208  Flow over a single, quasi-2D street canyon of infinite length oriented either in x- or in y-direction.
     209  The canyon size, orientation and location can be specified by the parameters [#canyon_height canyon_height] plus '''either''' [#canyon_width_x canyon_width_x] and [#canyon_wall_left canyon_wall_left] '''or'''  [#canyon_width_y canyon_width_y] and [#canyon_wall_south canyon_wall_south].
     210'' 'read_from_file' ''
     211  Flow around arbitrary topography.
     212  This mode requires the input file [#TOPOGRAPHY_DATA TOPOGRAPHY_DATA]. This file contains the arbitrary topography height information in m. These data must exactly match the horizontal grid.\\\\
     213Alternatively, the user may add code to the user interface subroutine [#user_init_grid user_init_grid] to allow further topography modes. These require to explicitly set the [#topography_grid_convention topography_grid_convention] to either '' 'cell_edge' '' or '' 'cell_center' ''.\\\\
     214Non-flat '''topography''' modes may assign a kinematic sensible [#wall_heatflux wall_heatflux] and a kinematic [#wall_humidityflux wall_humidityflux] (requires [#humidity humidity] = .T.) or a [#wall_scalarflux wall_scalarflux] (requires [#passive_scalar passive_scalar] = .T.) at the five topography faces.\\\\
     215All non-flat '''topography''' modes require the use of [#momentum_advec momentum_advec] = [#scalar_advec scalar_advec] = '' 'pw-scheme' '', [#psolver psolver] /= '' 'sor' '',  [#alpha_surface alpha_surface] = 0.0, [#galilei_transformation galilei_transformation] = ''.F.'', [#cloud_physics cloud_physics]  = ''.F.'',  [#cloud_droplets cloud_droplets] = ''.F.'', and [#prandtl_layer prandtl_layer] = ''.T.''.\\\\
     216Note that an inclined model domain requires the use of topography = '' 'flat' '' and a nonzero alpha_surface.
