Way cool. Did you know that gravity varies significantly all over the surface of the earth as well? This is primarily due to changes in the density and thickness of the earth's mantle and crust. There is a satellite that is mapping the earth's gravity as well from space, which I believe will actually assist eventually in improving water management in Cambodia since it is so flat and the variance in gravity can actually affect water flows as a result.
I knew the strength of gravity is variable around the planet, and that 'being close to a mountain' means that you come under its gravitational attraction - but I didn't know that the differences from place to place were big enough to affect water flow in a flat country. Interesting.

We'll have to wait on the completion of the data collection and processing, but the very coarse data they had prior to the satellite indicated changes of larger than a meter between Battambang and Takeo in terms of the impact. Gravimetric surveys are one of the most expensive and valuable geology tools available, usually flown via helicopter. Someone already did it in Cambodia, but given the cost and value of the data, not surprisingly it hasn't been shared.Chuangt2u wrote:I knew the strength of gravity is variable around the planet, and that 'being close to a mountain' means that you come under its gravitational attraction - but I didn't know that the differences from place to place were big enough to affect water flow in a flat country.

It would be interesting to see whether stronger gravity can indeed make water flow uphill (although ocean tides do this every day) and to what extent that effect could affect Cambodia.
