Restoring ravines – or mega-gullies – is done by replanting robust vegetation and building small earth dams in the ravine. This slows the velocity and destructive power of runoff water, reduces the amount of runoff water and allow the ravine to recover by depositing sediments.
These simple structures remain fragile. Through study and observation the techniques used have improved through the years. With the support of friends and family more resources were deployed, more and larger dams were placed in the ravine.
Thanks to the experience gained in recent years, the dams now offer more resistance to the enormous power of the rising water.
Moreover, sediments deposited behind the dams after every heavy rain, allowed for the first time in more than a decade to achieve ravine restoration.
