This document presents site features and cross-sectional diagrams used for Hydrus-Slice hydrological modeling of the Sea-Tac Third Runway Embankment Fill project. It shows fill depths ranging from 0 to 160 feet across multiple modeled slices, with cross sections identifying impervious areas, elevation contours, and the watershed divide between Miller Creek and Walker Creek. The figures were produced in November 2001 as part of environmental engineering analysis for the third runway construction.

A 2001 technical memo from Hydrocomp, Inc.'s Norm Crawford outlines recommendations for hydrological modeling of Miller, Walker, and Des Moines Creeks near Sea-Tac Airport's new runways and taxiways. The document describes how surface runoff and groundwater flow from both impervious runway surfaces and surrounding pervious grasslands should be calculated and linked across three modeling tools: HSPF, Hydrus, and the Slice model. Key recommendations include properly accounting for infiltration, reducing till seepage by 33% for inactive groundwater recharge, and reconciling discrepancies in land area calculations between the different models.
