Our neighbours are all chatting about it, but I think we're OK for now. There's this website which tells you what's going on with the Ping river and even if you can't read Thai (like me) you can still work out if it's going to flood or not. Here's how:
1. Go to HYDRO-1 CENTER CHIANGMAI
2. Click on menu item 6 in the menu on the left
3. Click on the top table that looks like this:
4. What you get is a table showing critical measurements in two locations.
P1 is the River Ping at the Narawat Bridge. The banks overflow (in the absence of any action by local authorities) at 3.70m and 440 m3/sec. You can see above that at 5am on 14 August, it was at 2.74m and 254 m3/sec, so no danger. You can also see that the level has been falling, not rising.
P67 is a point some 6-7 hours north of P1 (travelling at the speed of the water). This is interesting, because if P67 gets to 4.00m and continues rising, 6-7 hours later P1 will be at 3.70m and will also continue rising, so it's likely that Chiang Mai will flood unless the army boys get off their arses and start carting sand bags around.
That is the end of the tutorial.
