Creatig a drainage network file

• 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
