Well ... the rivers ...
In fact those rivers are not really rivers in the usual sense. This island is in a Tropical area and so is having a very special hydrological system.
During the Tropical storm season, rain is like deluge ant that explain the huge erosion inland, the deep valleys and why the huts village in Djo and Gha basin are build on terrain higher area. Those part are flooded by fresh water in a matter of hours. ^^
So even, if it seems incredible, those rivers are rivers only a few weeks each years. After the tropical storm season, salted water began it slow conquest and just before the rain season, the so called rivers are a place for salted or more or less brackish water that's the reason why it's populated by mangrove.
At the moment, some plants and trees are more or less trying to look like mangrove ... but I hope that with the brand new Berghoff African foliage, released today it will change for good.
The plane ...
As there are special links between some people in the North of Tropica and people from what was USSR ... remember the soviet had built the Banga airport as a spare for Buran emergency landings ... you must not beeing surprised by the landing of a Russian IL-76.
