TWW - SWMM correspondances --------------------------- Title/Notes: ^^^^^^^^^^^^ No correspondance in TWW. This parameter must be set by the user in the template ``.inp`` file or before running the simulation. - Copied from the template input file if exists. Options: ^^^^^^^^ No correspondance in TWW. This parameter must be set by the user in the template ``.inp`` file or before running the simulation. - Copied from the template input file if exists. Climatology: ^^^^^^^^^^^^ No correspondance in TWW. This parameter must be set by the user in the template ``.inp`` file or before running the simulation. - Copied from the template input file if exists. Hydrology: ^^^^^^^^^^ **Rain Gauges [Gages in SWMM]:** TWW_SWMM creates one raingage for each subcatchment. By default: - Time serie: Each raingage is related to a default rain time serie called ``default_tww_raingage_timeserie``. The time serie must be created and the value Series Name updated accordingly. - Other parameters have default SWMM values See ``vw_swmm_raingages.sql`` for details. **Aquifers:** TWW_SWMM creates an aquifer for each TWW ``aquifer``. By default: - An aquifer is created for each TWW ``aquifer`` - 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 See ``vw_swmm_aquifers.sql`` for details. **Subcatchment:** TWW_SWMM creates a subcatchment for each TWW catchment area. By default: - A subcatchment is created for each TWW ``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 than the outlet. - The coverages (attribute land uses) are computed from the intersection between the catchment area and the planning zone (see ``vw_swmm_coverages.sql``) - SWMM Dry Weather Flow: - are set to 0 for rain water subcatchments - are set to ``waste_water_production[_current,_planned]`` if set - else it computed from the subcatchement area and ``population_density[_current,_planned]`` - Other parameters have default SWMM values The subcatchment can be linked to an aquifer via the groundwater attribute. See ``vw_swmm_subcatchments.sql``, ``vw_swmm_subareas.sql``, ``vw_swmm_dwf.sql`` and ``vw_swmm_coverages.sql`` for details. **Snow Packs** No correspondance in TWW. This parameter must be set by the user in the template ``.inp`` file or before running the simulation. - Copied from the template input file if exists. **Unit hydrographs** No correspondance in TWW. This parameter must be set by the user in the template ``.inp`` file or before running the simulation. - Copied from the template input file if exists. **LID Controls** No correspondance in TWW. This parameter must be set by the user in the template ``.inp`` file or before running the simulation. - Copied from the template input file if exists. Hydraulics ^^^^^^^^^^ **Junctions** - TWW_SWMM creates a junction for each TWW manhole, some kind of special structures and the wastewater nodes linking primary pipes without a wastewater structure. See ``vw_swmm_junctions.sql`` for details. **Outfalls** - TWW_SWMM creates an outfall for each TWW discharge_point. See ``vw_swmm_outfalls.sql`` for details. **Dividers** - TWW_SWMM creates a divider for the manholes and special structures having the function ``separating_structure`` - See ``vw_swmm_dividers.sql`` for details. **Storage Units** - TWW_SWMM creates a storage for some kind of TWW infiltration installations and some kind of TWW special structures. - See ``vw_swmm_storages.sql`` for details. **Conduits** - TWW_SWMM creates a conduit for each TWW reach. - Roughness is created from ``coefficient_of_friction``, ``wall_roughness`` or ``swmm_default_coefficient_of_friction`` (see: :ref:`Coefficient-Of-Friction`) - TWW profile type are matched to SWMM profile type, dimensions are computed from ``reach.clear_height`` and ``pipe_profile.height_width_ratio`` - Custom pipe profile described by a curve are currently not exported - See ``vw_swmm_conduits.sql`` and ``vw_swmm_xsections.sql`` for details. **Pumps** - TWW_SWMM creates a pump for each TWW pump. When a curve ``tww_od.hq_relation`` is liked to the pump it is exported as a SWMM curve. - See ``vw_swmm_pumps.sql`` and ``vs_swmm_curves.sql`` for details. **Orifices** No correspondance in TWW. Orifices are not created from TWW objects. An empty table is created - See ``vw_swmm_orifices.sql`` for details. **Weirs** - Are created from TWW prank weir (without H/Q relation) and leaping weir. - See ``vw_swmm_weirs.sql`` for details. **Outlets** No correspondance in TWW. However, outlets are created to export TWW prank weir having a H/Q relation. - See ``vw_swmm_outlets.sql`` for details. **Transects** No correspondance in TWW. This parameter must be set by the user in the template ``.inp`` file or before running the simulation. - Copied from the template input file if exists. **Controls** No correspondance in TWW. This parameter must be set by the user in the template ``.inp`` file or before running the simulation. - Copied from the template input file if exists. Quality ^^^^^^^ **Land uses** - TWW_SWMM creates a SWMM land use kind for each TWW planning zone kind. - See ``vw_swmm_landuses.sql`` **Pollutants** No correspondance in TWW. This parameter must be set by the user in the template ``.inp`` file or before running the simulation. - Copied from the template input file if exists. Curves ^^^^^^ - Are created for pumps linked to a ``tww_od.hq_relation`` and for wastewater structures linked to a ``tww_od.hydr_geom_relation`` - See ``vw_swmm_curves.sql`` for details. Time series ^^^^^^^^^^^ No correspondance in TWW. This parameter must be set by the user in the template ``.inp`` file or before running the simulation. - Copied from the template input file if exists. Time patterns ^^^^^^^^^^^^^ No correspondance in TWW. This parameter must be set by the user in the template ``.inp`` file or before running the simulation. - Copied from the template input file if exists. Labels ^^^^^^ No correspondance in TWW. This parameter must be set by the user in the template ``.inp`` file or before running the simulation. - Copied from the template input file if exists.
