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 Β± 47 Γ— 10^9^ m^3^/year) and suspended sediment load (325 Β± 57 Γ— 10^6^ 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 NiΓ±o–Southern Oscillation (ENSO) show a relationship. Copyright Β© 2009 John Wiley & Sons, Ltd.

## Abstract Before 1900, the Missouri–Mississippi River system transported an estimated 400 million metric tons per year of sediment from the interior of the United States to coastal Louisiana. During the last two decades (1987–2006), this transport has averaged 145 million metric tons per year. Th

The mean annual flow of the lower Ebro river has reduced by 29% during this century (592 to 426m3 s-I). The main causes are increased water use and evaporation from reservoirs in the river basin. The losses due to irrigation explain 74% of the decrease, whereas losses by evaporation in the reservoir

The planned restoration of the lowermost 18 km of the Skjern river system (catchment area 2490 km 2 ) through re-meandering the river to its former course and the creation of a shallow lake and ponds is the largest river restoration project in Europe. An important aspect of the project planning and
