Extending Allegheny County Hydrology Data for the Nine Mile Run Watershed

Posted on by

DESCRIPTION

Publicly available 2015 Allegheny County high resolution QL2 LiDAR data and corresponding orthophotos from the same year provide excellent starting points for creating a hydrologic surface that can be used for basin analyses in urban environments. For the Nine Mile Run Watershed in Allegheny County, PA, county-wide hydroenforced data were used to further develop a higher resolution hydrologic dataset. This derivative dataset was then used to model the effects of the urban environment on surface water flow. These types of enhanced hydrology datasets are valuable for sub-basin catchment analyses and peak flow calculations within the watershed. This workflow established a repeatable data development and data improvement process that can be followed for similar hydrology extension projects using the forthcoming statewide QL2 LiDAR dataset for Pennsylvania and beyond.
