    Abstract

    Among the large rivers rising on the Tibetan Plateau and adjacent high mountains, the discharge and suspended sediment load of the Ayeyarwady (Irrawaddy) River are the least well known. Data collected between 1969 and 1996 at Pyay (Prome) are analysed to provide the best available modern estimate of discharge (379 � 47 �109 m3/year) and suspended sediment load (325 � 57 �106 t/year) for the river upstream of the delta head. A statistical comparison with data collected in the nineteenth century (1871 to 1879) shows discharge has significantly decreased in the last ?100 years. Regression and correlation analyses between discharge in the modern period and indices of El Ni�outhern Oscillation (ENSO) show a relationship. Copyright � 2009 John Wiley & Sons, Ltd.
