How to fill lid controls catalog

Edgar Fuste edited this page Nov 2, 2021 · 1 revision

As SWMM works with LID's Giswater works with LID's also.

You need to fill catalog table (inp_lid_control) before to work with the usage table (inp_lid_usage table). To fill catalog remember that: factor colums are related to different values in function of LID strategy choosed.

EXAMPLE 1: RAIN BARREL EXAMPLE

To create a RAIN BARREL (using lid name (lidco_id) as RB-1) you need to mix STORAGE & DRAIN objects, using syntax defined below:

id lidco_id lidco_type value_2 value_3 value_4 value_5 value_6 value_7 value_8
1 (serial) RB-1 RB
2 (serial) RB-1 STORAGE 36 0 0 0
3 (serial) RB-1 DRAIN 10 0.5 0 6

EXAMPLE 2: GREEN ROOF WITH IMPERMEABLE BOTTOM

To create a GREEN ROOF with impermeable bottom (using lid name (lidco_id) as GR-1) you need to mix SURFACE & SOIL & STORAGE & DRAIN objects, using syntax defined below:

id lidco_id lidco_type value_2 value_3 value_4 value_5 value_6 value_7 value_8
1 (serial) GR-1 BC
2 (serial) GR-1 SURFACE 3 0 0 0 0
3 (serial) GR-1 SOIL 3 0.5 0.1 0.05 1.24 2.4
4 (serial) GR-1 STORAGE 3 0.5 0 0
5 (serial) GR-1 DRAIN 5 0.5 0 0

For LID's with Surface layers:

value_2 : StorHt
value_3 : VegFrac
value_4 : Rough
value_5 : Slope
value_6 : Xslope

For LID's with Pavement layers:

value_2 : Thick
value_3 : Vratio
value_4 : FracImp
value_5 : Perm
value_6 : Vclog

For LID's with Soil layers:

value_2 : Thick
value_3 : For
value_4 : FC
value_5 : WP
value_6 : Ksat
value_7 : Kcoeff
value_8 : Suct

For LID's with Storage layers:

value_2 : Height
value_3 : Vratio
value_4 : Filt
value_5 : Vclog

For LID's with Underdrains layers:

value_2 : Coeff
value_3 : Expon
value_4 : Offset
value_5 : Delay

See Appendix D: Command line SWMM [LID_CONTROLS] section (EPA SWMM user's manual 5.0.22) for more information
NOTE: As SWMM have been improved on 5.1 version, you can generate inp compatible with 5.1 version LID's control usign the same strategy to create your LID CONTROLS but taking a look on user's manual of your 5.1 SWMM version
