Expansion on Time
Intersection of Olifants and Selati Rivers
Repeating the three steps of the parallel extension of sub rivers, the transverse filter slopes placement and sediment recycling allows the wetlands to grow out over time, While adjusting the seasonal water and soil problems, the expansion of wetland is carried out by taking advantage of the alternation of the dry season and the flood season. During the dry season from June to September, excavation is carried out to collect sediment and build sandbars, and excavate sub rivers and plants.Surface runoff filtration during flood season.
