Erik Strandhagen to Discuss Stormwater Analysis at Annual GIS Conference

Integral Senior Scientist, Erik Strandhagen, GISP, will present at the “Geographic Information System (GIS) In Action” conference on April 17, 2014, at Portland State University in Portland, Oregon. The presentation, titled “Hydrologic Analysis of Stormwater Source Controls,” is coauthored by Integral staff Michael Martin, P.E.; David Livermore, R.G., L.H.G.; and Eric Bushèe. This annual geospatial information conference is hosted by the Columbia River Region of the American Society of Photogrammetry and Remote Sensing, and the Oregon-Southwest Washington Chapter of the Urban and Regional Information Systems Association..

Mr. Strandhagen will describe how GIS methodology was used to support effective stormwater modeling at a former industrial site in Portland, Oregon. To model stormwater source control measures, Mr. Strandhagen performed a hydrologic drainage analysis of the preconstruction and post-construction digital elevation models utilizing ArcGIS software and the ArcHydro extension. The GIS hydrologic analysis identified topographic depressions, catchments, longest flow paths, and land cover to support storm event modeling. This GIS methodology can be applied to a variety of other sites and is another component of Integral’s comprehensive approach to stormwater management.

Integral’s stormwater management services address planning, sampling, design, engineering, and compliance at the facility level and for entire drainage basins. With 12 years of experience, Mr. Strandhagen has comprehensive expertise in spatial hydrologic modeling, geostatistics, advanced gridding analysis, and integrated calculations of chemical body mass and volume for soil, sediment, groundwater, and geologic 3 dimensional subsurface site models.
