thumbnail new Modeling Copper River Flows to Protect the Copper River Highway in Alaska –USGS, in cooperation with the Alaska Department of Transportation and Public Facilities, assessed and modeled hydrology and flow conditions along the Copper River Highway, which traverses the wide alluvial fan before the large, glacier-fed river enters the Gulf of Alaska. The highway is at risk because of its low grade, stream channel reconfiguration, and possible flooding by high flows of the Copper River. The USGS FaSTMECH model was used to simulate design highway changes and diversion channels to accommodate varying levels of flows. (Full report)

 

thumbnail new Assessing Lake Storage to Accommodate Flooding in Burned Areas of Coconino County, Arizona –USGS, in cooperation with Coconino County, Arizona, and the U.S. Forest Service, used geophysical surveys and boreholes to assess storage capacity at Cinder Lake, which was used to capture flood waters resulting from massive fires northeast of Flagstaff that burned more than 15,000 acres. The flooding in areas downgradient of the burn resulted in extensive damage to private lands and residences, municipal water lines, and roads. Channels were built to move the waters away from communities into Cinder Lake. USGS techniques helped the County to determine how much could be diverted and stored in the underlying cinder deposits and alluvial deposits. (Full report)

 

thumbnail new Flood Inundation Maps for communities in New York –Digital flood-inundation maps for parts of the West Branch Delaware River through the Village and part of the Town of Delhi, New York were created by USGS, in cooperation with the Village of Delhi, the Delaware County Soil and Water Conservation District, and the Delaware County Planning Department. Delhi has experienced severe flooding along the West Branch Delaware River; most notably during January, 1996, June, 2006, and October, 2010, and August, 2011. Emergency responders benefit from a library of flood-inundation maps that are referenced to the stages recorded at the USGS streamgage upstream from Delhi. By referring to the appropriate map, emergency responders can discern the severity of flooding (depth of water and aerial extent), identify roads that are or will soon be flooded, and make plans for notification or evacuation of residents in harm's way based on current and near-future flood levels.

thumbnail new Flood Inundation Maps Available in Atlanta and other parts of Georgia –USGS, in cooperation with partners such as the City of Atlanta, estimate the areal extent and depth of flooding corresponding to selected water levels at USGS streamgages at Peachtree Creek at Atlanta, Georgia and at Chattahoochee River near Atlanta, Georgia. Access these and other maps at the Georgia Flood Inundation website.
