Heads Up Boys & Girls---River on the Rise

[Gonzo the Face]

For all of those concerned or interested the river is on the rise.   From last evening at 8 PM,  up almost a half meter.  Still on the rise.

[Gonzo the Face]

 Belay that..... past hour remained level.  But still  keep an eye opened    .......  maybe some dew will fall.

Instead of gold.......theres a lot of rain in them thar hills!

[Sandy Freckle]

3 drops of rain on a cigarette paper is enough to stop me from......, 

[naboo]

It's OK, the dam south of Chiang Mai will help the flow. 

[Bung]

That dam in Padaet has one section completely opened up now and sth of the dam a good flow can be seen. Seems to be working. 

[Thailand]

Saw they had been releasing water via the PaDaet dam this morning, seemed to be having the desired effect but certainly a lot rain in the past few days starting to test the newer defences.

There is in CM two retired senior 'Mechanical Engineers' one Yank and one from down under.

Both have told me completely independent of the other that an inflatable 'Wier' would solve much of CM's problems.

Low water inflate, rising water deflate.

Very old technology that they claim works.

i dont know about from last night but its certainly risen about 18 inches

since pic 1 was taken six days ago 

 

to the two pics from this afternoon

A point of question Dave,,,, are those level markings in feet and inches or metric?   I would think that being here it would be metric.

[Dante99]

Those measurements are in Leagues/2000, the common measurement by local hydrologists.

[mamborobert]

Are you sure about that Dante or being funny (I hope).  When I have seen these about town (Wat Ket especially)  they always look like centimetres/metre marks, notwithstanding that they may report in other measures elsewhere or in both.

 

The P1 marker at Nawarat is certainly metric. and reports I have noted over the last ten ears or so (sample below) are using hydrology measures in metrics for Chiang Mai

 

3.2

Historical flood map and flood warning system.  The severe floods usually arrive during August and September. The recent ones (in the past 20 years) occurred in 1994, 1995, 2001, 2005, and 2011 with maximum water levels at the P1 station of 4.43, 4.27, 4.18, 4.93 and 4.94 m, respectively. From an experience in observed flood routing from past flooding events between input flood hydrograph at stream gauge P.67 (Ban Mae Tae, 32 km upstream of P1) and output hydrograph at P1, it was found that if the maximum depth of flood at P.67 equals 4.70 m, the maximum depth of flood at P.1 equals 3.7 m, within about 7-8 hrs later(Chatchawan, 2005). Based on this correlation and observed relationship between flood level at P1 and flood depth measured in the city during flood events, flood warning system for Chiang Mai city was set up in the form of flood hazard maps. Chiang Mai flood maps given by Civil Engineering Natural Disaster Research Unit (CENDRU) Chiang Mai University divides inundation areas into seven zones depending on upstream referenced water level at P1 (Chatchawan, 2005; CENDRU, 2013).

for your viewing pleasure the most recent  p67 v p1 comparison i have seen and as Gonzo noted went up quite a bit in the first 8 hours today, updated figures and graphics for the Ping are available at the Hydro site.

A league is not a vertical measurement, rather a horizontal one.  One league is a unit of distance equal to 3.0 statute miles (4.8 kilometers).

Ok then..., so maybe the Jules Verne novel "20,000 leages under the Sea" ..., was written about a very large organisation of fish playing soccer under the sea?

Should I start to think about investing in a dinghy?

Dante may not have been funny but that is a chuckle.

...around here you don't have to be dinghy to think that way

 

...and.....   How highs then water mama ?

 

anybody remember that ???

Good answer, but no cue-pee [ Kewpie ] doll.

 

If, like me, you're oldern  dirt, and still have some memory left maybe this  will  ring a bell.

If the  Padaet Dam wasn't there the excess water would have gone a long time ago wouldnt it ? or is that too simplistic. I dont know. Someone on this forum when it was constructed, suggested that the dam is to keep the water near the city in dry times and boat owners happy.Conspiracy theory? Any water experts on here.

[Sandy Freckle]

Just as a side issue..., can anyone remember the last time there was flooding inside the moat ?

Correct, the weir controls water level in CM cbd at a near constant level.

Last big downpour caused surface flooding.

Problem with old city area is poor drainage and I hope draining of northern moats is an attempt to mitigate real flooding. 

[evenstevens]

without any researching, this rainy season to E/S    is about the norm, perhaps just up some,  so no need for any  hot wind heads up, at this point of time

from  E/S  residing  here   2001...2005....2011,  was indeed heads up  time,

its a Barry White  good nite to all

Is it a weir or is it a dam, or is it a damn weir?
