- Description
- This publication serves as notice of intent to procure services for the Department of Commerce (DOC), National Oceanic & Atmospheric Administration (NOAA), Pacific Marine Environmental Laboratory located in Seattle, WA on a sole source basis with Humboldt-Innovation GMBH. The government intends to acquire services using FAR Part 13, Simplified Acquisition Procedures. Proposed vendor will develop, test and implement 2D models of the characteristics of waves generated by landslides. The NOAA Center for Tsunami Research (NCTR) located at the Pacific Marine Environmental Laboratory (PMEL) in Seattle, WA USA is working on a comprehensive tsunami hazard assessment of U.S. coastlines for the Nuclear Regulatory Commission (NRC). The assessment is based on tsunami generation, propagation, and inundation modeling. An important research topic necessary for this comprehensive endeavor is the understanding of the generation of tsunami waves caused by landslides. Two and three-dimensional modeling is crucial for characterizing the resultant tsunami wave in order to evaluate the potential threat for the near and far field. The major task will be to extend the currently two-dimensional models to three dimensions. The available 3D version of iSALE was designed to model meteorite impact processes. The approach is to adjust the 3D impact code to landslide modeling analogous to the 2D models. However, 3D modeling has high demands on computing power, and the available 3D code is not on the same development level as the 2D version and does not provide the same functionality yet. In particular multi-material handling needs to be implemented and computation efficiency has to be improved to enable the simulation of landslides and the generation of tsunamis with the 3D code. The aim is taking first steps towards 3D modeling of landslides with iSALE including: 1. Implementation of the multi-material handling, the crucially important first step. 2. Identification of required computation power for 3D models (such estimates depend to a large extent on an efficient implementation of multi-material handling) 3. Set-up of typical landslide geometries. To improve computation efficiency, special boundary conditions at the slope are required. 4. Implementation of landslide specific rheology models (analogous to 2D modeling) 5. Benchmarking and validation.The first steps will be performed at the Humboldt-University, Berlin, (2 months) where the model is currently used and no extra time for installation and adjustment to the available computer hardware is required. The work will then be continued at PMEL in collaboration with scientists of NCTR. The primary deliverable is implementation of improved 2D models of the characteristic of waves generated by landslides. An additional deliverable is a first generation basic approach towards 3D modeling of landslides. A report on the use of the model will be provided and personnel at the NOAA Center for Tsunami Research will be trained in the use of the implemented model. Results of this work should be published in international journals. Results will be presented at the annual meeting of the American Geophysical Union (AGU) 2008 in San Francisco in December 2008. Other associated deliverables may also be provided, as governed by the evolving needs of the project. The NOAA Center for Tsunami Research does not yet itself have the capability to conduct modeling of landslide generated tsunami. For this reason, the NOAA Center for Tsunami Research will collaborate with Dr. Wünnemann, who has developed the iSALE model. Originally developed by Dr. Wünnemann for modeling of meteorite impact, iSALE can be adapted for landslide modeling. Based on the 2D models that were developed during the first period of the project it is planned to implement further improvements to meet more realistic conditions for the generation of tsunami waves by landslides. The first study demonstrated that accurate description of material behavior is of crucial importance for the resulting wave signal. Some work will be spent on further improvements in material modeling. The government intends to negotiate a firm- fixed price contract with a period of performance that will start from date of award and will end January 31, 2009. This notice of intent is not a request for competitive proposals. However, all proposals received within 15 days of publication of this synopsis will be considered by the government. All responses must be in writing and may be faxed attention to Maria Mendoza at (206)527-7513or email at maria.l.mendoza@noaa.gov. This is a small purchase action estimated value not to exceed $100,000.00. ****The Western Regional Acquisition Division, requires that all contractors doing business with this Acquisition Office be registered with the Central Contractor Registry (CCR) as of October 1, 2003. After this date, NO award can be made unless the vender is registered in CCR. For additional information and to register in CCR please access the following web site: http://www.ccr.gov. In order to register with the CCR and to be eligible to receive an award from this acquisition office, all offerors must have a Dun & Bradstreet Number. A Dun & Bradstreet number may be acquired free of charge by contacting Dun & Bradstreet on-line at www.dnb.com/eupdate or by phone at (800) 333-0505. All contractors are also required to complete online Representations and Certifications at HTTP://ORCA.BPN.GOV.
