7.11. Changer les paramètre de simulation

La manière la plus facile pour éditer les paramètres de simulation et d’ouvrir le fichier « .inp » avec l’application SWMM. Les paramètres peuvent être changer dans SWMM, la valeur initiale est reprise, si disponible, de la base de données TEKSI assainissement (p.ex. sections, hydrauliques) ou copié du fichier template « .inp ».

7.11.1. Title/Notes:

  • Set by the user as a QGEP_SWMM option

  • update title if necessary.

7.11.2. Options:

  • Copied from the template input file if exists.

  • set / update simulation parameters.

7.11.3. Climatology:

  • Copied from the template input file if exists.

  • set / update climatology parameters

7.11.4. Hydrology:

Rain Gages:

QGEP_SWMM creates one raingage for each subcatchment.

By default:

  • Time serie: Each raingage is related to a default rain time serie called default_qgep_raingage_timeserie. The time serie must be created and the value Series Name updated accordingly.

  • Other parameters have default SWMM values

Aquifers:

QGEP_SWMM creates an aquifer for each QGEP aquifiers.

By default:

  • An aquifer is created for each QGEP aquifiers

  • The bottom elevation is set to the minimal_groundwater_level

  • The water table elevation is set to the average_groundwater_level

  • Other parameters have default SWMM values

Subcatchment:

QGEP_SWMM creates a subcatchment for each QGEP catchment area.

By default: - A subcatchment is created for each QGEP wastewater_networkelement linked to the catchment area (max. 4: fk_wastewater_networkelement_rw_current, fk_wastewater_networkelement_rw_planned, fk_wastewater_networkelement_ww_current, fk_wastewater_networkelement_ww_planned) - it is linked to a rain gage. - The width is computed from the mean of the minimal / maximal distance between the outlet and the catchment area contour. If the outlet is unknown the centroid is used rather thant the outlet. - The coverages (attribute land uses) are computed from the intersection between the catchment area and the planning zone - Other parameters have default SWMM values

The subcatchment can be linked to an aquifer via the groundwater attribute.
