DCS Hydrology Submission for Lincoln County, Oregon

공공데이터포털

The hydrology dataset for Lincoln County, Oregon includes proposed 10-, 50-, 100-, and 500-year discharges for Salmon River, Schooner Creek, Drift Creek, Siletz River, Olalla Creek, West Olalla Creek, Alsea River, Yachats River, Yaquina River, Depot Creek, and Big Creek. Proposed discharges were determined using a log-Pearson Type III, flood frequency analysis of USGS gages with the computer program HEC-FFA, and regional regression equations.

Floodplain Redelineation Submission for Lincoln County OR

공공데이터포털

The Floodplain Mapping/Redelineation study deliverables depict and quantify the flood risks for the study area. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual- chance flood event, and areas of minimal flood risk. The Floodplain Mapping/Redelineation flood risk boundaries are derived from the engineering information Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA).

DCS Hydraulics Submission for Clearwater County FY20

공공데이터포털

Recent developments in digital terrain and geospatial database management technology make it possible to protect this investment for existing and future projects to a much greater extent than was possible in the past. The minimum requirement for hydraulics data includes input and output files for all hydraulic models and spatial datasets that are needed to implement the models.
