-<h2>NAME</h2> <I>i.eb.h_SEBAL95 </I>- computation of <i>sensible heat flux</i> [W/m2] after Bastiaanssen, 1995 in [1].

-<b>DEM</b>=name
-<b>T</b>=name
-<b>RH</b>=name
-<b>WS</b>=name
-<b>NSR</b>=name
-<b>Vh</b>=name
-<b>ETP</b>=name
-
-<h2>DESCRIPTION</h2>
-
-<p><em>i.eb.h_SEBAL95</em> given the vegetation height (hc), humidity (RU),
-wind speed at two meters height (WS), temperature (T), digital terrain model (DEM),
-and net radiation (NSR) raster input maps,
-calculates the sensible heat flux map (h0).
-
-<p>Optionally the user can activate a flag (-z)
-that allows him setting to zero all of the negative evapotranspiration cells;
-in fact these negative values motivated by the condensation of the air water
-vapour content, are sometime undesired because they can produce computational
-problems. The usage of the flag -n detect that the module is run in night hours
-and the appropriate soil heat flux is calculated.
-
-<p>The algorithm implements well known approaches: the hourly Penman-Monteith method as presented in Allen et al. (1998) for land surfaces and the Penman method (Penman, 1948) for water surfaces.<br>
-
-<p>Land and water surfaces are idenfyied by Vh:<br>
-- where Vh less than 0 vegetation is present and evapotranspiration is calculated;<br>
-- where Vh=0 bare ground is present and evapotranspiration is calculated;<br>
-- where Vh more than 0 water surface is present and evaporation is calculated;<br>
-
-<p>For more details on the algorithms see [1].
-
-
-<h2>OPTIONS</h2>
-
-The program will run non-interactively if the user specifies program
-arguments and flag settings on the command line using the following
-form:
-
-<p><b>i.eb.h_SEBAL95</b> <b>[ -qzd ]</b>
-<b>DEM</b>=name
-<b>T</b>=name
-<b>RH</b>=name
-<b>WS</b>=name
-<b>NSR</b>=name
-<b>Vh</b>=name
-<b>ETP</b>=name
-
-
-
-<p>Alternatively, the user can simply type <em>i.eb.h_SEBAL95</em> on the
-command line and the program will ask for parameter values and flag
-settings interactively, using the standard GRASS parser interface.
-
-
-<h3>Parameters:</h3>
-<dl>
- <dt><b>DEM</b>=<I>name</I>
- <dd>Input elevation raster [m a.s.l.]. Required.</dd>
-
- <dt><b>T</b>=<I>name</I>
- <dd>Input temperature raster [�C]. Required.</dd>
-
- <dt><b>RH</b> =<I>name</I>
- <dd>Input relative humidity raster [%]. Required.</dd>
-
- <dt><b>WS</b> =<I>name</I>
- <dd>Input wind speed at two meters raster [m/s]. Required.</dd>
-
- <dt><b>NSR</b> =<I>name</I>
- <dd>Input net solar radiation raster [MJ/(m2*h)]. Required.</dd>
-
- <dt><b>Vh</b> =<I>name</I>
- <dd>Input vegetation heigth raster [m]. Required.</dd>
-
- <dt><b>ETP</b> =<I>name</I>
- <dd>Output evapotranspiration raster [mm/h]. Required.</dd>
-
-</dl>
-
-
-<h2>NOTES</h2>
-
-<p>Net solar radiation map in MJ/(m2*h) can be computed from the combination of the r.sun ,
-run in mode 1, and the r.mapcalc commands.
-
-<p>The sum of the three radiation components outputted by r.sun (beam, diffuse, and reflected)
-multiplied by the Wh to Mj conversion factor (0.0036) and optionally by a
-clear sky factor [0-1] allows the generation of a map to be used as
-an NSR input for the <em>i.evapo.pm</em> command.
-<br>
-example:
-<br>r.sun -s elevin=dem aspin=aspect slopein=slope lin=2 albedo=alb_Mar incidout=out beam_rad=beam diff_rad=diffuse refl_rad=reflected day=73 time=13:00 dist=100;
-<br>r.mapcalc 'NSR=0.0036*(beam+diffuse+reflected)';
