The 2004 tsunami deposits and probable paleotsunami deposits were studied at the southern Kho Khao Island, on Andaman Sea coast of Thailand. The 2004 tsunami laid down about 8?cm of fining upward medium sand and locally about 40?cm of massive coarse sand with common mud clasts. The sediments were characterized by the presence of marine foraminiferal assemblage; however, already after 5?years many of carbonate foraminiferal tests were partly or completely dissolved. The probable paleotsunami deposits form layer about 1?m thick. It consists of massive very coarse sand with common big shells and mud clasts. Its composition suggests a marine origin and the presence of mud clasts, and similarity to the 2004 tsunami deposits suggests that the layer was left by paleotsunami, which took place probably during the late Holocene, even though two shells within the layer gave ¹⁴C ages of 40,000?years or more.  相似文献   

Groundwater development in the CCOP countries: challenges and opportunities     

Niran Chaimanee 《Environmental Earth Sciences》2013,70(5):1951-1956

CCOP stands for Coordinating Committee for Geoscience Programmes in East and Southeast Asia—an intergovernmental organization comprising of eleven Member Countries: Cambodia, China, Indonesia, Japan, Malaysia, Papua New Guinea, the Philippines, Republic of Korea, Singapore, Thailand and Vietnam. CCOP’s mission is to facilitate and coordinate the implementation of applied geoscience programmes in the region to contribute to economic development and an improved quality of life within the region. As an intergovernmental geoscience organization, CCOP organizes its activities in seven programmes, including the groundwater programme, which promotes capacity building, technology transfer, exchange of information and institutional linkages for sustainable groundwater resource development in CCOP Member Countries. The overview of the status of groundwater development within the CCOP Member Countries will be elaborated highlighting quantity and quality challenges for its sustainable development. Some examples of challenges are the large numbers of people in these regions that still have no access to an improved water source; decline in the availability of freshwater, particularly in large river basins due to global warming; saltwater intrusion; arsenic pollution of groundwater, etc. Finally, the emphasis of the importance of capacity building in sound groundwater management will be shown as the contribution of CCOP to its members. The recommendation to capture the opportunities for groundwater development in CCOP Member Countries will be presented and discussed.  相似文献
