- Description
- The U.S. Army Corps of Engineers, Philadelphia District, intends to award on a sole source basis to University of Delaware, Center for Applied Coastal Research, Department of Civil and Environmental Engineering, Newark, Delaware 19716. The work consists of 1. Data acquisition and input preparation for numerical morphological model CSHORE and enhancement of CSHORE capabilities in predicting wave overwash, barrier island migration, and beach recovery. 2. Data acquisition and input preparation for numerical storm surge and wind wave models using unstructured numerical grids. The specific tasks for Part 1 are as follows. 1a. Calibration and Verification of CSHORE Using Field Data The cross-shore model CSHORE has been calibrated and verified using small-scale and large-scale laboratory data with no or minor overwash. Preliminary comparisons with the beach profile data at Ocean City, MD for the Halloween 1991 storm, 11 November 1991 storm, and 4 January 1992 storm indicate the need to modify the formulas for suspended sediment and bedload transport rates in the wet and dry zone for the case of major overwash. CSHORE with the modified sediment transport formulas will be compared with the available beach profile data at Dewey Beach and Rehoboth Beach in Delaware for the December 1992 storm. Deliverable One journal paper and one conference paper to document the modified CSHORE and its comparisons with several laboratory and field data sets. 1b. Detailed Evaluation of CSHORE Using Overwash Experiment The evaluation of CSHORE in Task 1a is based on the comparison between the measured and computed beach profiles. For the case of significant overwash, it is necessary to examine the accuracy of the predicted wave overtopping and overwash rates. An experiment is being conducted to measure the rates of wave overtopping and overwash of a dune in a wave tank. The progression of the dune profile lowering and narrowing will be measured for different initial dune profiles in order to evaluate the accuracy of CSHORE. This detailed evaluation is necessary for the accurate prediction of the volumes of water and sediment transported landward during a storm. Deliverables One technical report for the experiment and the evaluation of CSHORE. One journal paper based on the technical report. 1c. Extension of CSHORE for Barrier Island and Beach Recovery The landward end of CSHORE is presently limited to dry land. CSHORE will be extended to predict wave transmission and sediment transport into a bay side so that CSHORE can be used to predict the landward migration of a barrier island, as well as the landward migration of a ridge with a runnel during beach recovery. An experiment will be conducted in the wave tank used in Task 1a to calibrate and verify the extended CSHORE. An additional experiment will be conducted for a barrier island or a ridge on a hard bottom (peat layer) to examine the effect of limited sediment availability on suspended sediment and bedload transport. This extension of CSHORE will be necessary to apply CSHORE to a barrier island or ridge situated above the peat layer. Deliverables One technical report for the experiments and the calibration and verification of the extended CSHORE. One journal paper summarizing the technical report. 1d. Documentation of CSHORE 2009 CSHORE is being extended to a permeable wet and dry zone so as to predict coarse sediment beach profile evolution. An experiment is being prepared in a separate wave flume to calibrate and verify the permeable CSHORE. Deliverables Journal paper for the permeable CSHORE. User's manual for CSHORE 2009 which includes all the extensions made in 2009. 1e. Water Level, Wave and Beach Profile Data in Delaware The Delaware beach profile data during 1991 to 2008 will be assembled. The corresponding water level and wave data will be acquired, analyzed, and processed for the calibration and verification of CSHORE for FY2010. D eliverables 1) Data file for water level data during 1991 to 2008. 2) Data file for wave data during 1991 to 2008. The specific tasks for Part 2 are as follows: Parallel coupling of STWAVE, ADCIRC and C2SHORE The final goal of the work is to use the Earth System Modeling Framework (ESMF) to couple large-scale ocean models, STWAVE and ADCIRC, and small-scale sediment transport model, C2SHORE in a multi-grid system for application on the Delaware coast. The current work will focus on developing ESMF friendly versions (initial-run-finalize scheme) of existing computational codes, creating ESMF compliance for each code and building couplers for the coupled system. A preprocessing script will be written to allow easily updating with new versions of computational components (e.g., new parallel versions of STWAVE, both the half plane and the full plane versions). The model-coupling framework will be tested on a Linux cluster or a Unix system with parallel computational capabilities. Extensive model tests with model/data comparisons in a particular domain (e.g., Delaware coast) may be conducted in the next FY. The coupling between ADCIRC and STWAVE is to be a two-way coupling using ESMF and MPI. The coupling between ADCIRC-STWAVE and C2SHORE is to be a one-way coupling at this time (with information passing from ADCIRC-STWAVE to C2SHORE). The coupled system is to run in both serial and parallel modes. The detailed specifications to fulfill the final goal are listed below. There will be exactly one ADCIRC domain. Allow for more than one STWAVE domain, which will require running more than one instance of STWAVE simultaneously in parallel Allow for multiple C2SHORE grids and therefore multiple instances of C2SHORE, the C2SHORE grids will not necessarily be the same as the STWAVE grids (Plan for next FY.) Use a pre-defined global mapping file (fort.25a) that specifies the mapping from STWAVE grids to ADCIRC mesh. Use pre-defined global mapping file (fort.25b) that specifies the mapping from ADCIRC mesh to each STWAVE grid. Use a pre-defined coupling file (fort.cp) that specifies input parameters specific to the coupling. Similar mapping files (4 and 5) and input files (6) will exist for C2SHORE and should be used accordingly (Plan for next FY) Constructs and calls from ESMF will be used to enable the parallel (MPI) communications and coupling. For example, using ESMF array constructs in conjunction with the global mapping files (fort.25a and fort.25b) should facilitate the physical topology mapping being transferred to a mapping in memory, as ESMF arrays carry memory/processor location information. Use appropriate mapping function to perform the regridding. Deliverables Source codes of the COUPLER program, EMSF compliant, makefile script and modified computational components. Users' manual and technical report No RFP will be issued based on this notice. However, all information received within five (5) calendar days after date of publication of this notice will be considered SOLELY for the purpose of determining whether to conduct a competitive procurement in the future. A determination by the Government not to open the requirement to competition based upon responses to this notice is solely within the discretion of the Government. The Government will not pay for information received. The NAICS code is 541690.
