I have been thinking about the sabotage and the flooding of the moat that was being built. The only people who would have died would wave been in the blast zone of the bomb that destroyed the dam.

Here is why. The river has always been talkted about to be more than 15 deep, 100 feet wide and the dam was about 30 feet wide (which was also reinforced as well.

Now the pressure you may think would be great on that dam especially the river would be moving at 1.5 mph. Sounds a lot but in actually it is not. Here is why.

The movement of the water is perpendicular to the dam and is constantly moving away. So the only force of the water that is static on the dam would be the first few inches to about a foot of water  that would be pushing against the dam.

Now with that said, I calculated the dam would hold over 500,000  lb of pressure if it was not reinforced. The pressure against the dam is more than half of that.

Lest say there is about 250,000 lb of dirt that needs to be moved. thats about 125 tons of explosive force to bust open the dam.

SO ... to clear the dam wide open and to flood at maximum rate, you need about 104 sticks of dynamite of force. Now, I doubt the  explosive that was used would have been as strong as that. In fact, it probably would have weaken the dam and it then broke open with a 5-10 foot gap at first then open up in the next few minutes.

Also the length of time it would take to flood  the moat would take over 30 minutes. Here is why... remember the river is moving perpendicular to the dam at 1.5 mph. Well, if the dam is head on the river, it would fill up with that rate of flow. It is 4000 feet distance, it's 0.75 miles. so 30 minutes to fill.

BUT... since the moat is 90 degrees to the river it will fill at a slower rate.

SO... the toilet bowl flush you first described could have not happened. First, the explosive needed to be equivalent to 100 tons of force. Second, the rate of fill would need in minutes would have been a head on to the river and have a speed of 15 mph (10 times faster).

One other point would be the fact that the moat may be still in sections and the flooding would have stopped at multiple levies or dams.


so... the range of 1000 people hurt and most of them survived is actually a lower number. It should be just about everyone survived except the few in he blast radius.

Please keep in mind that there are more things between heaven and hell than are even dreamed of in your philosophy, sport. Especially in D&D. Anything is possible. Never mind arguing with your "this is SCIENCE!!" nonsense.

So we playing at my place tonight, right?

Mutt

sure but I'm out early. 10:30 or so, so if you can start early it would be better
