The karst immersion and waterlogging is one of the typical and the most harmful natural disasters in southern karst areas of China. It is threat to the local production and life for a long time. In recent years, due to the construction of more reservoirs, the disaster became serious. This article takes immersion and waterlogging of Banwer's subterranean rivers in Yantan reservoir area as an example, researches the daily rainfalls reflection to the water level of reservoir depression, discusses characteristics of immersion and waterlogging of the valley, analyzes the disaster index in detail, such as water level process, the highest water level, sensitive rainfall, original waterlogged rainfall and delayed day numbers etc., and provides the reference as a basis to the disaster analysis.
