Cambodia and Vietnam - December 24th, 2011

This APM image shows the Mekong Delta region in southwestern Vietnam, and stretches into Cambodia in the upper part of the full image. The Mekong Delta region is the area of Vietnam where the Mekong River approaches and empties into the sea through a network of distributaries.

The Mekong delta region encompasses a large portion of southwestern Vietnam of 39,000 square kilometres (15,000 sq mi). The size of the area covered by water depends on the season. The region displays a variety of physical landscapes, ranging from mountains and highlands to the north and west to broad, flat flood plains in the south (such as those visible in this image).

The city covers an area of 678.46 square kilometres (262 sq mi), with some 11,401 hectares (28,172 acres) in the municipality. The agricultural land in the municipality amounts to 34.685 square kilometres (13 sq mi) with some 1.476 square kilometres (365 acres) under irrigation.

Cambodia and Vietnam - November 7th, 2011

This APM image shows the Mekong River crossing Cambodia and flowing past Phnomh Penh, towards Vietnam (visible in the lower part of the full image). Located on the banks of the Mekong, Phnom Penh is the capital and largest city of Cambodia.

The Mekong is the world’s 10th-longest river and the 7th-longest in Asia, with an estimated length of 4,909 km (3,050 mi). It drains an area of 795,000 km2 (307,000 sq mi), discharging 475 km3 (114 cu mi) of water annually. The extreme seasonal variations in flow and the presence of rapids and waterfalls in this river have made navigation extremely difficult.

Wetlands of the Tonlé Sap, Cambodia – October 30th, 2011

Cambodia - October 29th, 2011

The Tonlé Sap, visible as a light green area in the center of this image, is a combined lake and river system of major importance to Cambodia. It is the largest freshwater lake in South East Asia and an ecological hot spot that was designated as a UNESCO biosphere in 1997.

The Tonlé Sap is unusual for two reasons: its flow changes direction twice a year, and the portion that forms the lake expands and shrinks dramatically with the seasons. From November to May, Cambodia’s dry season, the Tonlé Sap drains into the Mekong River at Phnom Penh. However, when the year’s heavy rains begin in June, the Tonlé Sap backs up to form an enormous lake.

Thailand - October 24th, 2011

This wide-swath ASAR image shows hills and lakes in Thailand (below) and Laos (above). The large lake just above the image center is the reservoir created by the Nam Ngum Dam on the Nam Ngum river, a major tributary of the Mekong in Laos.

Visible to the south is the reservoir created by the Ubol Ratana Dam (formerly known as the “Phong Neeb Dam”), a multi-purpose dam located in Tambon Kok-Soong, Ubol Ratana District, approximately 50 km north of Khon Kaen, Khon Kaen Province, Thailand. It was the first hydroelectric power project developed in the Thailand’s northeastern area of Isan. The dam impounds the Nam Phong, a tributary of the Mekong River.
