Creatig a drainage network file
- Obtain a drainage network with MOHID GIS in [Basins]
- Alternatively can also obtain a drainage network with program BasinDelimiter (from SourceSafe) with a basin.dat with the keywords, adapted to the study watershed:
TOPOGRAPHIC_FILE : ..\..\GeneralData\DTM\MDT200mSD.dat TRESHOLD_AREA : 100000 DELINEATE_BASIN : 1 OUTLET_I : 1 OUTLET_J : 44 WRITE_REACHES : 1 REACHES_FILE : ..\..\GeneralData\DrainageNetwork\DrainageNetwork.dnt
- Define the cross sections for the drainage network file in MOHID GIS.
DO NOT FORGET TO SELECT SAVE ALL IN MOHID GIS TO UPDATE THE FILE!!!
(Currently in this version of the cross sections program keyword TERRAIN_LEVEL is not written, instead is written BOTTOM_LEVEL (old version). TERRAIN LEVEL = BOTTOM_LEVEL + HEIGHT. Change it for example with excel, new program should be written)
- Define the network file just created in the drainage network data file with:
NETWORK_FILE : ..\..\GeneralData\DrainageNetwork\DrainageNetwork.dnt

Sample
NETWORK_FILE : ..\..\GeneralData\DrainageNetwork\DrainageNetworkAlcabrichel_100ha_terrain.dnt CHECK_NODES : 1 CHECK_REACHES : 1 HYDRODYNAMIC_APROX : 1 MASS_ERR : 0.001 GLOBAL_MANNING : 0.06 MIN_WATER_DEPTH : 0.01 INITIAL_WATER_DEPTH : 0.0 XS_CALC : 1 DOWNSTREAM_BOUNDARY : 1 TIME_SERIE_LOCATION : ..\..\GeneralData\Timeseries\TimeSerieLocation_200_new.dat OUTPUT_TIME : 0 864000 DISCHARGES : 1 (1-if have a discharge file; 0 if not discharging) CONTINUOUS : 0 MAX_DT_FLOOD : 100 STABILIZE : 1 DT_FACTOR : 0.75 STABILIZE_FACTOR : 0.05 MINIMUM_SLOPE : 0.0001
If want to model Properties
Than additionaly to the above options need to define properties to be modelled. One block for each property (see a list
<beginproperty> NAME : salinity UNITS : psu DESCRIPTION : salinity DEFAULT_VALUE : 0.3 MIN_VALUE : 0.0 ADVECTION_DIFUSION : 1 !1-want to transport property; 0 - no transport DISCHARGES : 0 !1-property is discharged;0 - no discharges TIME_SERIE : 1 WATER_QUALITY : 0 !1-use water quality model for property transformation;0-no transformation <endproperty>
