Thanks a lot Krey for all that amazing content! One remark and one short question: If you have different inundation areas, but model values with no velocity or no depth as noData, you will miss them out when using the RasterCalculator (because noData - something still is noData). Some areas might have no flood hazard class before and then change to 5 but still wont be displayed in the difference map. Rather type: If d = NoData OrElse v = NoData Then Output = 0 ‘H0 no water ... and the difference map will also cover regions which were not wet in the before case. My question is if it is possible to display the difference terrain layer above the MapLayer, so that the difference map can be transmissive and the underlying map layer will be displayed in full color?
Dear sir, I am very much keen to know how *.h5 or *.hdf data can be read and displayed on web interface (say directly or sort of other readable converted format). I really need to understand how it works? Thank you in advance for your time, and helps.
Ok so the process of preparing H1-H6, requires a hybrid, of the hazard calculated at each time slice, then merged for all time slices does it not? This is a very exhaustive process (Easy enough to code however). This being the case back in 2008 I looked into a better method to define Hazard that does not require the three values of 'Depth", 'Velocity" and 'DepthxVelocity' noting that VxD is simply the MOMENTUM of the flowing water, so why not call it that??? Any way the algorithm that I came up with resulted in a curve very much shaped like that by Trieste (1988) The definition is: Hazard = D*(1+V^2) = (0.1,0.2...1,2,....etc) Please create this as a hazard in HEC and see for yourself the benefits of this definition compared to H1-H6.

What an amazing 2021 start, very good! Another challenge: can you explain how to produce a gridded data with HEC-DSS file format, from HEC-MetVue, to input in HEC-RAS has a gridded precipitation (saw that in the first part of the video (near minute 34: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-5zszZC1XcQU.html)? Thanks!
