dry wood decomposes thermally into
volatile matter and char (fixed carbon). Volatile matter released from the solid fuel forms
during combustion. Char is mostly carbon, while volatile matter is a mixture of various
dry rivers, etc.) and quality (eutrophication, organic matter pollution, saline intrusion, etc.) The value of this criticality ratio that indicates high water stress is based on expert judgment and experience (Alcamo and others, 1999). It ranges between 20 % for basins with highly variable runoff and 60 % for temperate zone basins. In this map, we take an overall value of 40 % to indicate high wa
monotony produced by a low scrubby vegetation and large tracts of undifferentiated flat terrain. This is not, for one moment, to suggest that it shouldn't be World Heritage listed. The abundance of wildlife, particularly birdlife, which flocks into the swampy areas of the park during the dry season demonstrates how important it is to the fauna of the area. It's just not an area of great beauty.
