A number of provinces up north here, over the years, have been systematically doing just that.
Attempting to redirect overflowing seasonal water with newly created khlongs and huge holding ponds....to be used later for general aggie purposes and whatnot.
Yet, it's still a challenge for some provinces that have a diversity of elevations.
Flooding has always existed here and always will.....by the very nature of the heavy seasonal rains, combined with the natural composition of the loamy clay soil.
Nonetheless, a very wet and saturating September running into October.
