A tree lies in the shallows of the Mekong River. Flooding along the river, in northern Cambodia, often leads to forests being destroyed. "Flooding is a way of life along the lower Mekong River in Vietnam and Cambodia. Every year between August and November, monsoon rains fill the rivers of Southeast Asia, and the Mekong River Delta broadens well past its dry season levels. The annual floods carry nutrient-rich silt to farmland around the river and provide the moisture needed to grow vast fields of rice", according to NASA's Earth Observatory.
