Import sections and cross profiles in text format

It is possible to import sections from text files containing tables with values separated by tabs, on several lines. This file can be at the formats described below, or be a Mascaret geo file.

In the case of a text file, all formats managed by SIC are available:

  • L or 1 = Section of type Width - Elevation
  • A or 2 = Section of type Abscissa - Elevation
  • C or 3 = Section of type Circular
  • D or 4 = Section of type Culvert
  • P or 5 = Section of type Power
  • R or 6 = Section of type Rectangular
  • T or 7 = Section of type Trapezium

If behind this letter or this number is added the letter s or S (attached, without space), this section will be considered as singular (to insert one or more device (weir, gate, etc.).

Example :

section_234 $   145782.9 $ $ 0 $ A $  45.089584 $   9.902083
 -174.223              39.000
 -173.065              38.312
  173.065              38.312
  174.223              39.000
ld_Isola-Serafini $   146338.4 $ $ 0 $ As $  45.092918 $   9.900417
  -57.613              38.000
  -55.546              36.403
   55.546              36.403
   57.613              38.000
section_236 $   147124.1 $ $ 0 $ A $  45.099583 $   9.897083
 -125.365              32.880
 -124.500              32.486
  124.500              32.486
  125.365              32.880

To access the Import window sections of a reach, there are two possibilities:

  • Select a reach, make a right-click and choose "Import sections" in the context menu;
  • In the description window of a reach, click the "Import" button at the top of the window.

These tables can be quite varied in format (see below).

Before each abscissa-elevation table, a line allows to import the general data of the section, separated by the characters $ (dollar).

  1. Section name
  2. Abscissa (in m)
  3. Minor-Medium elevation overflow (for minor-medium bed section) or distance for the major bed (for a major bed section). Just leave space character is the section is just a minor bed section.
  4. Section type : 1 for major bed section, 0 for minor bed section or minor-medium bed section if the minor-medium elevation overflow is filled. You can also just put a space character if the section is just a minor bed section
  5. Format of the section with a letter of number code (L or 1, A or 2, C or 3, D or 4, P or 5, R or 6, T or 7). Additional letter s or S if the section is singular (for a cross device such as weir, gate, etc) (Ls, As, Cs, etc)
  • # Latitude in decimal degrees or in metric unit (option)
  • # Longitude in decimal degrees or in metric unit (option)
  • # Geolocation reference of the section (option, soon)
  • # Lateral offset of the geolocation reference (option, soon)
  • # Angle of the section with respect to a reference (option, soon)

The abscissa and the overflow elevation are optional. In the absence of values (or just one or several space characters), the abscissa default will be 0 and the section will be considered as a minor bed section (without overflow minor-medium bed elevation). If the section format is not given the Abscissa- Elevation format will be supposed (therefore corresponding to the A or 2 code).

For the format Width - Elevation (code L or 1) we also have access to 2 possibilities : normal or transposed, with the same idea as above but with Width instead Abscissas.

For the parametered formats the transposed mode does not exist. Data must be given under the following format:

C or 3 = Section of type Circular:

Radius
Bank Elevation <tab> Bed Elevation

D or 4 = Section of type Culvert:

Width<tab> Side slope
Bank Elevation <tab> Bed Elevation

P or 5 = Section of type Power:

Width<tab> Coeff Power
Bank Elevation <tab> Bed Elevation

R or 6 = Section of type Rectangular:

Width
Bank Elevation <tab> Bed Elevation

T or 7 = Section of type Trapezium:

Width<tab> Side slope
Bank Elevation <tab> Bed Elevation

   25.096              17.318

The interpolation space step DX can also be specified in the file. The format is:

DX=00000500.0;

If this file is created by the software Matlab, the write format is for example:

fprintf(fidout,'%s%010.1f%s\r\n','DX=',PasDX,';');

The first "DX=" line found will be attributed to the whole reach. The next ones, if any, will be attributed to the following sections until a new one is specified. The "DX= lines" must always be written before a section data line (cf example above).

Import command line

If large numbers of reaches must be created, it is possible to automate this import by calling the software from the command line with multiple profile files as parameters, either in the options of the command line, or in a edisic.mac file. For more information, see dedicated chapter.
