Vu Gia Thu Bon River Basin

The pilot region encompasses the whole Vu Gia-Thu Bon river basin as well as adjacent areas of the provinces Da Nang and Quang Nam, with a total area of 12,382 square kilometers (VGTB 10,350 square kilometers).

Rainfall totals 2000-4000 mm per year, which accounts for 60-80% of rainfall during the rainy season from October to November.

The topography is characterized by the highland in the west with mountains reaching up to 2000 m a.s.l. as well as extensive lowlands along the coast in the east (see Topographic Map). About 75% of the area is covered by forest, agricultural land accounts for around 11% (220.040 ha, of which 61% is used for rice cultivation) and 5% is urbanized (MONRE, 2010).
