However, theWakeby distribution provides a better fit than LP3 for large flood events (p_(exc) < 0.1)at three of the four stations, and results in further increases (0.6 to 1.8 ft) in theestimated 100-yr flood elevations. These increases have significant implications todelineation of the ...
Base Flood Elevation (BFE means a determination of the water surface elevations of the base flood as published in the Flood Insurance Study. When the BFE has not been provided in a “Special Flood Hazard Area”, it may be obtained from engineering studies available from a Federal, State, or...
Psychrometric Constant (γ) The Atmospheric Pressure (Pr, [KPa])is the pressure exerted by the weight of the atmosphere and is thus dependent on elevation (elev, [m]). To a certain (and limited) extent evaporation is promoted at higher elevations: $$Pr=101.3\ast {\left(\frac{293-0.0065...
Once the number of nodes is determined, we use this number to find break points along the high-resolution centerlines based on the flow distance and node length. Finally, we use the median location value of the high-resolution centerlines between each 200 m break point to define the node...
We present a case study of impacts of evolving nearshore bathymetry and topography on base flood elevations and provide a discussion of implications from various perspectives. The example site is located in Pacific County, Washington, on Long Beach. The sandy shore there is exposed to the Pacific...
The SWOT science team determined that a node length of 200 m was a good balance between preserving SWOT elevation and geolocation accuracies while maintaining a finer spatial resolution for representing river processes. To define nodes, we calculate flow distance along the high resolution GRWL ...
After extracting the road surface from the patches, edges are generated according to the rule of parallel to the road center line. The road width can be calculated after merging all patches. The road width was determined by the average distance from the edge points to the central line. The ...
, M variable is determined, such that more accurate classifications have a greater impact on the final prediction than less accurate ones. Because the accuracy of the basic 𝐻𝑚Hm classification is slightly higher than that of the random classification, the former are called weak 𝐻𝑚Hm ...
