So, as long as the science-based tag holds, I believe there's no way. Given that " The total electricity consumption of the Netherlands in 2013 was 119 terawatt-hour" (from Wikipedia), this works out to about three thousand times the total electricity budget for the whole Netherlands. If we want to flood Netherlands in ten years, we require 10 million such pumps, with an expenditure of some 500 trillion USD, and an energy requirement of 40 TW. Using OnoSendai's figure of 1.3E+16 cubic meters of water, to be raised on average 150 m, we get 0.3E+16 pump-seconds given that one year is 3E+7 seconds, it's 100 million pump-years.
It turns out that with about four megawatt of power you can raise six hundred cubic meters of water per second, one meter. Walling in the Netherlands and pumping water in requires some pumping. The kind of energy needed for such a bit of planetary reshaping is out of reach of our K0.73 civilization and, again, would probably wreck the planet in the bargain. The whole area is quiet and in the middle of the European plate. Enough snowballs to raise the sea level by 250+ meters would be enough to steam cook the planet, long before the steam condensed enough to contribute to the water level. What would actually happen is that the "snowballs" would explode in incandescent water vapour in the atmosphere. It takes 1.1 MJ to bring it to 0 ☌ and 0.334 MJ to melt it, leaving a net credit of 198 MJ, or 830000 kilocalories enough to bring eight tonnes of water to the boiling point. The alteration in salinity would wreck the oceanic circulation even more, and kill off a large(?) part of the sea life.Ī kilogram of ice at orbital speeds of 20 km/s and initial temperature of 10 K possesses a kinetic energy of 200 MJ. In this picture, the Chicxulub impactor is approximately the size of the dot on the "i" of "Chicxulub" (15 km diameter).Īlso, even if fragmented in an implausible string of smaller water comets, that quantity of water would get most coastal areas flooded everywhere on the whole planet and its kinetic energy would still wreck the weather systems (there's something of the kind in J. Multiplying that for a height of 300 meters gives around 30 million cubic kilometers of water, which, as a sphere, would have a radius of around 310 kilometers: forty times the size of the Chicxulub impactor, it would not be an asteroid but a small moon, the same size and one fourth the mass of Vesta. You could get away with a Grote Mandrenke, but no more (and you want "permanent").Īdding that much water through a "cosmic snowball" would require a more-than-Chicxulub-sized water asteroid: the kinetic impact alone would wreck the Earth.Īctually the surface of the Earth is 510 million square kilometers, of which about 80% is water to be raised.
I don't mind melting all that ice, but after that, I am about 260 meters of sea level rise short of entirely flooding the Netherlands, and I'm not sure if I can even get that amount of water.Ĭan I permanently and entirely flood the Netherlands, and if yes, how do I do it in as fast a way as possible?Īs you pointed out, there is not enough water on the Earth. At that rate, engineering is very likely to be able to keep up with rising sea levels, and I'll never succeed in flooding the country.Īlso, if I melt all the ice, on mountains and the poles, I sadly only have enough water for a sea level rise of about 216 feet/ 66 meters. Waiting for nature is a slow business though, at 2-3 mm a year. Wikipedia seems to suggest that apparently, a sea level rise of 65-130 cm by the year 2100 can be survived (with relative ease). This will mean that I need a sea level rise of about 330 meters, since the highest point in the Netherlands is the Vaalserberg at 322.4 meters above NAP and I want it flooded too. I want the Netherlands to be flooded entirely, and I want the event to be of such a scale that it goes faster than hydroengineering can keep up with.
