Last two weeks, some strong flash flood came and washed away, destroyed it. Nonetheless, nearly one foot of mud and eroded soil was trapped and controlled by the structure at the back.
I repaired it as Danny and Nong Endring were doing something else. The new structure. This time, more stones were put in the middle of a two-feet thick structure. It was cloudy when I took this photo.
This stone barrier was able to withstand the last flash flood. Lots of stones on the base, also deposited organic matter at the back.
The "long wall", left side.
Also three layers so far. Controlling topsoil erosion.
Even a deluge, Ondoy type of flooding will not be able to destroy this structure. Lots of big stones beneath, plus organic matter which have become soil already. Water from the flash flood will only pass at the top. The three layers slow down the flow and force of rampaging water. A big portion of the flash flood is actually trapped at the back, slowly sinks in after the rains have stopped.
This depression will soon become flat. The trees in this area grow faster. They have lots of organic fertilizers there.
Among the original stone terraces near the treehouse. Built in 2005 and still existing until now.
Stone stairs.
Our modest contribution at reducing soil erosion and flash flood.
