Purple inverted triangles mark gauge stations at Luang Prabang, Vientiane, Mukdahan, Pakse, Kratie, Chaktomuk, My Thuan, and Can Tho. Major place names include Miaowei, Linghong, Bassac, Tan Chau, and Vam Kenh. Latitude and longitude are labelled, a north arrow is provided, and a scale bar ranges from 0 to 200 kilometres.Map of the study area with gauge locations shown in pink triangles
