Applies to: parameters.storage_drain_params.drain_coef_1, parameters.storage_drain_params.drain_coef_2, parameters.wet_threshold
Where: Table 2(a), model parameter values by surface type, p. 223
Publishes Si 1.9 mm, D0,i 10 and b 0.013 in the Irrigated grass column. The same table explicitly labels site-specific initial states elsewhere, while these surface parameters carry no city label.
Where: Section 2.5, Equation 19, p. 224-225
States that paved surfaces, roofs and irrigated vegetation use the power-law drainage equation Di = D0,i(Ci,t-1)^b. It establishes the scientific form but does not print the SUEWS interface selector.
Applies to: parameters.storage_drain_params.drain_eq
Where: DrainageCoef1 configuration, SUEWS_Veg.txt example values, p. 62
Explicitly pairs DrainageEq 3 and DrainageCoef1 10 with Grass (irrigated). This evidence is scoped only to drain_eq; the exact physical coefficients remain sourced to Järvi et al. (2011).
Where: Table 4(a), parameters used in SUEWS by surface, p. 1701
The later compilation repeats irrigated-vegetation D0,i 10 and b 0.013 but leaves Si blank. Its caption points unfootnoted parameters back to Järvi et al. (2011).
| Name | supported Järvi et al. label the source surface Irrigated grass. |
|---|---|
| Target | supported The table and drainage equation publish storage and drainage parameters for the irrigated-grass SUEWS surface, matching land_cover.grass. |
| Values | supported Table 2(a) gives irrigated grass Si 1.9 mm, D0,i 10 and b 0.013, while Section 2.5 assigns irrigated vegetation to Eq. 19's power-law form. The official v2020a documentation separately pairs DrainageEq 3 with irrigated grass. Every stored value is therefore covered without treating a paper equation number as an interface selector. issue #1087 |
| Source | supported Järvi et al. (2011) directly publish the three physical parameters and drainage form. The source-only parameter override attributes the interface selector to the official v2020a documentation. Järvi et al. (2014) is retained only as compilation evidence; its Table 4(a) repeats D0,i and b but leaves the irrigated-vegetation Si cell blank, which does not supersede the original table. issue #1087 |
| Place | supported The original table presents a surface-type parameter rather than a Helsinki determination. Generic is therefore the supported evidence place; origin Helsinki preserves migration lineage. |
| Representativeness | supported The publication presents the tuple by surface type without a site-specific derivation, supporting generic rather than city representativeness. |
| Method | supported Literature accurately describes direct transcription of the published physical parameters, equation form and documented interface selector. |
| Identity | supported The original table distinguishes irrigated grass from grass and publishes different drainage forms and coefficients for them. The stable Helsinki path and origin retain migration identity. |
The previous unresolved finding came from treating a blank in the later Järvi et al. (2014) compilation as missing original evidence. Järvi et al. (2011) publishes the three physical parameters and equation directly; official SUEWS documentation establishes the separate selector mapping. The source and scope metadata are corrected without changing any parameter, target, stable path, origin or legacy ID.
