Delaware Bay, DE/NJ (M090) Bathymetric Digital Elevation Model (30 meter resolution) Derived From Source Hydrographic Survey Soundings Collected by NOAA

Bathymetry for Delaware Bay was derived from seventeen surveys containing 321,774 soundings. No surveys were omitted. The surveys dated from 1945 to 1993. The total range of sounding data was 3.7 meters to -47.0 meters at mean low water. Mean high water values between 1.3 and 1.8 meters were assigned to the shoreline. Seven points were found that were not consistent with the surrounding data. These were removed prior to tinning. DEM grid values outside the shoreline (on land) were assigned null values (-32676). Delaware Bay has twenty-six 7.5 minute DEMs and four one degree DEMs. The 1 degree DEMs were generated from the higher resolution 7.5 minute DEMs which covered the estuary. A Digital Elevation Model (DEM) contains a series of elevations ordered from south to north with the order of the columns from west to east. The DEM is formatted as one ASCII header record (A- record), followed by a series of profile records (B- records) each of which include a short B-record header followed by a series of ASCII integer elevations (typically in units of 1 centimeter) per each profile. The last physical record of the DEM is an accuracy record (C-record). The 7.5-minute DEM (30- by 30-m data spacing) is cast on the Universal Transverse Mercator (UTM) projection. It provides coverage in 7.5- by 7.5-minute blocks. Each product provides the same coverage as a standard USGS 7.5-minute quadrangle but the DEM contains over edge data. Coverage is available for many estuaries of the contiguous United States but is not complete.

Savannah River, GA/SC (S120) Bathymetric Digital Elevation Model (30 meter resolution) Derived From Source Hydrographic Survey Soundings Collected by NOAA

Bathymetry for the Savannah River was derived from nine surveys containing 34,353 soundings. Two older, overlapping, less accurate surveys were omitted before tinning the data. The average separation between soundings was 59 meters. Seven of the nine surveys used dated from 1934. The remaining two surveys, located in the southeast, dated from 1971 and 1974. The total range of sounding data was 1.2 meters to -15.9 meters at mean low water. Mean high water values between 1.9 and 2.5 meters were assigned to the shoreline. Three points were found that were not consistent with the surrounding data. These were removed prior to tinning. DEM grid values outside the shoreline (on land) were assigned null values (-32676). The Savannah River has seven 7.5 minute DEMs and two one degree DEMs. The 1 degree DEMs were generated from the higher resolution 7.5 minute DEMs which covered the estuary.

Cordova, Alaska Tsunami Forecast Grids for MOST Model

The Cordova, Alaska Forecast Grids provides bathymetric data strictly for tsunami inundation modeling with the Method of Splitting Tsunami (MOST) model. MOST is a suite of numerical simulation codes capable of simulating three processes of tsunami evolution: generation, transoceanic propagation, and inundation of dry land. Tsunami waves are computationally propagated across a set of three nested grids (A, B, and C), each of which is successively finer in resolution, moving from offshore to onshore. Nearshore details are resolved to the point that model output can be directly compared with tide gauge observations and can provide estimates of wave arrival time, wave amplitude and simulation of wave inundation onto dry land. A Grid Resolution: 60 arc-sec in x direction, 30 arc-sec in y direction. B Grid Resolution: 12 arc-sec in x direction, 6 arc-sec in y direction. C Grid Resolution: 4 arc-sec in x direction, 2 arc-sec in y direction.
