Interpolate Cross Section or 1D/2D River coupling in Open Flow FLOOD

Question

Versi&oacute;n: OpenFlows FLOOD CONNECT Edition (build 10.03.00.01). 
 Hello, 
 I am trying to acopling a river to a MOHID Land project by interpolating cross sections. However, I have an error with the file "Cross Section File". This error is "No cross section found in file". 
 For this reason, I would like to know what type of file is necessary to use the "1D / 2D River Coupling" and the "Interpolate Cross Section" tools and how generate this file (Cross Section File). 
 Thans,

Hello Alvaro, In OpenFlows FLOOD, when running the 1D/2D River Coupling tool you'll indeed require the Cross Section File. This file has a FLOOD specific format and currently it doesn't have an automatic tool to build it. However, the format is ASCII text file, so you may create it manually in a relatively straightforward way. The file format is as follows. For each river cross-section you need to create a "block" starting with and finishing with . I nside this block you add a keyword: NAME : XS001 with the name/id of the cross-section. Then still inside < BeginCrossSection> / you'll add a second block <>/ <> inside which you'll list 3 columns with X, Y and Z values for the cross-section. Here what the file should look like with 2 cross-sections: NAME : XS001 <> 384287.4 248624.9 13.21 384283.1 248635.4 12.03 384282.7 248636.3 10.55 384281.2 248640.2 10.74 384279.4 248644.6 12.97 384279 248645.5 13.57 <> NAME : XS002 <> 384189.1 248238.5 13.21 384187.8 248238.2 12.15 384183.2 248237.4 10.16 384180.8 248236.9 10.93 384180.3 248236.8 12.93 384180.3 248236.8 13.08 <> Please let me know if you require any additional information. Kind regards, Luis
