Ma River is the biggest in the Central of Viet Nam with the length of 512 km and stretching over two latitudes and longitudes, therefore, the basin’s meteorological and hydrological regime is very complicated. The current situation of hydro-meteorological network in the basin is unevenly distributed with a high density in the downstream, sparse or not in the upstream particularly a part of basin belongs Lao PDR’s territory that are challenges for flood forecasting and hydrological research. The contents of this paper will summarize, synthesize main natural geographic characteristic, meteorological, hydrological features, main weather conditions, causes of flood formation as well as analysis of monthly rainfall distribution which based on the long-term historical data. All of these will be indispensable information for developing of flood forecast approach or further hydrological researching for the Ma river basin in the future. Besides, some comments and suggestion are proposed in order to partially surmount the spatial rainfall data gap in the Ma river basin.
