Module DrainageNetwork

Other Features

Creatig a drainage network file

• Obtain a drainage network with MOHID GIS in Delineate 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

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
