“…To date, mainly onedimensional (1D) steady-flow models have been widely used to recreate the magnitudes of palaeofloods and the maximum water levels reached in the landscapes that they traversed. Chiefly, this approach has required a geometric representation of the floodway achieved through the provision of discrete simplified surveyed crosssections of the floodway and evidence from the landscape of maximum flooding levels (Pardee, 1942;Baker, 1973;Dorava and Meyer, 1994;Tómasson, 1996). The progression of the peak flood level down the system is not considered in these models but the flood is assumed to peak instantaneously and simultaneously at all sections.…”

“…Coordination with the Anchorage office of the USCG was the first of significance since the Mount Redoubt eruption in 1989-90 when lahars threatened the Drift River Oil Terminal ( fig. 1) and vessel traffic in Cook Inlet (Dorava and Meyer, 1994). AVO and the USCG discussed potential impacts of the range of eruption scenarios, reviewed estimated hazard zones depicted in the hazard report, and discussed what kind of emergency messages the USCG would issue in the event of an eruption.…”

Dissemination of volcano-hazard information in coordination with other Federal, State, and local agencies is a primary responsibility of the Alaska Volcano Observatory (AVO). During the 2005-6 eruption of Augustine Volcano in Alaska, AVO used existing interagency relationships and written protocols to provide hazard guidance before, during, and after eruptive events. The 2005-6 eruption was notable because of the potential for volcanogenic tsunami, which required establishment of a new procedure for alerts of possible landslideinduced tsunami in Cook Inlet. Despite repeated ash-cloud generating explosions and far-traveled ash clouds, impacts from the event were relatively minor. Primary economic losses occurred when air carriers chose to avoid flights into potentially unsafe conditions. Post-eruption evaluations by agencies involved in the response indicated weaknesses in information centralization and availability of specific information regarding ash fall hazards in real time. Volcano Hazard Warning System in Alaska Since its founding in 1988, AVO has been responsible for issuing hazard warnings pertaining to Alaska's active volcanoes. The three component agencies of AVO-the U.S. Geological Survey (USGS), the University of Alaska Fairbanks Alaska Interagency Operating Plan for Volcanic Ash Episodes Although AVO is responsible for detecting volcanic unrest and issuing notification of hazardous activity, the complete public warning process involves communication among a number of other State and Federal agencies, each of which have their own warning and information dissemination responsibilities and products (table 1). This multiagency response to volcanic activity in Alaska is documented in "The Alaska Interagency Operating Plan for Volcanic Ash Episodes" (Madden and others, 2008). In the first iteration of the plan published in 1994 after the 1992 eruptions of Mount Spurr, signatory agencies include USGS, NWS, FAA, Alaska Department of Homeland Security and Emergency Management (ADHSEM; then called the Alaska Department of Emergency Services or ADES), and the U.S. Air Force (USAF). The U.S. Coast Guard (USCG) was added in 2004 and the Alaska Department of Environmental Conservation, Division of Air Quality (ADEC/DAQ), was added in 2008. By design, the plan is updated approximately every 2 years and the 2008 revision represents the 5 th edition of the plan. The purpose of this document is to summarize each agency's key responsibilities and procedures in alerting each other and the public regarding volcano hazards. The emphasis until 2008 had been on airborne ash hazards to aviation; following the Augustine eruption, it was expanded to include protocols related to ash-fall hazards on the ground, particularly as reflected in air quality and impacts on public health. As the 2005-6 Augustine unrest progressed, the Interagency Plan was a principal organizing document that guided agency preparedness and communications. This was the first time the plan was used in response to a significant event near Anchorage.

“…Because wind direction and speed will control the movement of the ash plume, the areas most likely to receive ashfall are those in the zone of prevailing winds. (Dorava and Meyer, 1994). The largest of these occurred on January 2, 1990 and inundated Rust Slough, including parts of the Drift River Oil Terminal.…”

“…As a result of this process, increased flow in Montana Bill Creek ( fig. 9) initiated bank erosion that exposed, but did not rupture, a buried oil pipeline that crosses Montana Bill Creek north of the oil terminal (Dorava and Meyer, 1994).…”
