Description: The SRH-2D hydrologic model software was used in conjunction with the 2016 topography model of the Trinity River between Lewiston Dam and the North Fork Trinity River to estimate flows and fish habitat at a variety of flow rates. The model opperates within a two dimensional mesh of variable cell sizes. Wetted area output directly from the model therefore follows model mesh cells, yeilding a blocky configuration to the wetted area extent.For the data presented here, the water surface elevation estimates for mesh cells were used to develop a water surface (ArcGIS Terrain format), which was intersected with the 2016 topography model (also ArcGIS Terrain format) for a more accurate representation of the actual aeiral extent. Post intersection processing included the removal of polygons covering less than 5 ft2, smoothing of the angular results that come from Terrain intersection, and manual removal of a few modeling artifact polygons where major tributaries approach the river and at the tight river bend in Junction City. See the lineage section of these metadata for details.
