Research purposes: To establish indicators of WRS for river basins in Viet Nam which are appropriate to charateristics and water use of basins; To use the proposed indexs to assess WRS for typical regions in Ma river basin; subsequently, proposing oriented solutions to make WRS feasible and appropriate to real conditions. | MINISTRY OF EDUCATION AND MINISTRY OF AGRICULTURE TRAINING AND RURAL DEVELOPMENT THUYLOI UNIVERSITY NGUYEN THI MUI STUDY ON WATER RESOURCES SECURITY FOR SUSTAINABLE DEVELOPMENT OF MA RIVER BASIN Major Soil and Water Environment Specialized Code 9 44 03 03 SUMMARY OF TECHNICAL PHD THESIS HANOI 2018 1 The research is completed at Thuyloi university Scientific instructor Prof. Dr. Le Đinh Thanh Name of Supervisor 1 Name of Supervisor 2 Name of Supervisor 3 The dissertation shall be defensed at the Thesis Assessment Board of the University at . on .

Rationales At present WRS WRS has become a major and urgent issue for many river basins and regions in the world especially for transnational river basins and water-scarce territories. The Ma river basin is considered to be a place where has limited potentiality of water. However there are still tensions in the exploitation and use of water resources for the following reasons i The unequal distribution of water resources both in terms of space and time has caused floods and droughts affecting the exploitation and use of water among regions in the basin ii Disasters floods and droughts on the Ma river system frequently occur iii The hydrological regime in the main stream and on the tributaries of the Ma River basin has changed a lot due to the consequence of the construction and exploitation by small and medium water-use works in the basin. In addition extremely unusual weather patterns and climate change are also major causes of storms floods and depletion of water resources in the basin iv Water in the basin has been seriously polluted specially on the Lung Lach Truong Yen rivers and downstream of the Ma river. To contribute more scientific and practical foundations for planning exploitation and management of water resources with an aim to promote more sustainable socio-economic development and more effectively .
