I may not have understood all the science, but I very much appreciate the computer simulation and the original photography. Very helpful in understanding how massive it really was. Thank you!!!
Thanks for all the hard work simulating this disaster. I grew up in Scituate, MA in the 1970s and lived in the area in the 1980s & 90s. I visited friends who lived in the North End back at that time and remember Giorgio's Pizza and Bova Italian Bakery fondly. I have family who adopted 2 cats from the bakery and named them after it (Bova & Bee). Fond memories. Now in Boston, "as slow as molasses in January" is no joke! Edit: add stuff
Hello Cody, Yes, the Hope Slide might make a good target for simulation. I did publish a You Tube that features the Chehalis Lake (BC, Canada, 2007) landslide and tsunami that might interest you. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-X3LuT1lP00c.html Thanks.
Hello Fake Farmer, Yes, some call the Mosul Dam the most dangerous in the world. It is built atop slowly dissolving rock. A bad choice! A few months ago I did run a simulation of its failure... es.ucsc.edu/~ward/mosul-map.mov The simulation has not yet made it to the "You Tube" stage. Thanks.
Just a suggestion: you may have more viewership if you add some sort of audio/voiceover so the audience isn't simply sitting in silence. Great videos otherwise
ingomer200 in the ~1970s* west virginia had one of the worst, if not the worst flood in its history caused by a collapsing dam. make a simulation for a video on the tsunami *couldve been earlier/later then the ~1970s
Yes Thanks LegendCraft69 Gaming, That would be the Buffalo Creek Flood of 1972. 500,000 m^3 escaped. It might make a good video. That case seems very similar to a recent movie I did called Bento Rodrigues Mine Disaster.mov ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-k0PWRiEWMTY.html 70 million m^3 escaped there.
+ingomar200 I need to tell you that molasses is a shear thinning fluid,meaning that it gets thinner with more force. Considering the fact that it is 5 stories high,gravity would thin all that molasses for a while. Many science websites shared this. That is why it travelled at 54kph at the start.
Hello Daniell, Yes, just how to implement frictional resistance to flow in this story is a matter of debate. Total frictional resistance is some function of flow velocity and flow thickness, F(V,H) Likely, resistance goes up as velocity increases and flow thickness decreases. One functional class of intrinsic resistance is shear thinning as you mention. Even within this class however you have a huge leeway in implementation of F(V,H). Keep in mind that you really want to simulate Total Frictional Resistance not just intrinsic viscous friction -- the molasses has to push air out of the way for example. There is an additional dynamic drag force here. I chose the total frictional de-acceleration equal to Const*(Flow Velocity^2)/(Flow thickness) with the constant adjusted to match the observed extent of the flow. This seemed to work well, but there may be other equally good choices. Regardless of details, one end member that everyone can agree on is the "no friction at all" case that was shown in the video. This gives the 35mph initial flow rate, but clearly contradicts observations of flow extent.
