INTRODUCTION: The Inception Meeting among Department of Meteorology and Hydrology (DMH) Nay Pyi Taw Office, other related Myanmar government offices and ADB Consultant Part II-A & -B for TA-8456 was held on 16 September 2014 with the presence of 38 participants. Objective The objectives of this meeting are: (1) to inform the participants about the Part II of the Capacity Development Technical Assistance, Transformation of Urban Management (TA-8456) including its objectives, scope, methodology, draft work plan, expected major activities and outputs; (2) to establish a scheme for collaboration among the participants; and (3) to identify major issues and needs for flood management in Myanmar, in particular for the three cities (Yangon, Mandalay and Mawlamyine). The TA promotes sustainable urban development in Myanmar towns by building institutional capacity of local authorities, leading to the prioritized needs-based provision of essential infrastructure. The TA comprises Part I: Urban Management (Yangon, Mandalay, Mawlamyine, Pathein, Lashio, and Monywa) and Part II: Flood Management (Yangon, Mandalay, and Mawlamyine). The Executing and Implementing Agencies of the TA are as follows. Executing Agency: The Ministry of Construction (MOC) through the Department of Human Settlements and Housing Development, implementing Agency of Part I: The Urban Research and Development Institute, MOC Implementing Agency of Part II: The Department of Meteorology and Hydrology (DMH), Ministry of Transport The Part II of the TA aims to strengthen institutional capacity and sustainability of DMH for flood management by conducting a hydro-meteorological analysis related to floods in the Ayeyarwady River basin, a hydro-meteorological analysis related to floods and storm surges in the Yangon plain and the Thanlwin River basin, risk assessment for these river basins, and related training programs. Expected Outcomes The expected outcomes of the meeting were: Participants are informed about the Part II of TA-8456 Transformation of Urban Management and share their expectations on the project; and Participants build a scheme for collaboration for strengthening flood management for Yangon, Mandalay and Mawlamyine. Participants identify issues and needs for flood management in Myanmar. II.
