  journal={Hydrological Processes},
The decrease of river runoff draining into Lake Balkhash in Central Asia was investigated using hydrological and meteorological data over a long‐term period. The data from the difference integral curves of the annual runoff from 1911 to 1986 suggested that a low‐flow period began in 1970 in the River Ili, and in 1973 in the east rivers, continuing until 1986. Compared with the runoff before 1969, the decrease of runoff in the upper reaches of the River Ili was less than those in the middle and… 

Runoff variations in the Luanhe River Basin during 1956-2002

The decrease of runoff in the Luanhe river basin, which caused water crisis in Tianjin for several times, was investigated using discharge data covering the period 1956–2002. The data from the

Patterns of Lake Balkhash water level changes and their climatic correlates during 1992-2010 period

The variation in Lake Balkhash water levels during the period from 1992 to 2010 and their relationship with climate dynamics were investigated in this study, using satellite altimetry data and

Impacts of climatic change on river runoff in northern Xinjiang of China over last fifty years

Challenges to the sustainable use of water resources in the Ili River basin of Central Asia

Water is a scarce resource in Central Asia, and many catchments span international boundaries, among them that of the Ili River, which is shared by China and Kazakhstan. Since 1970, the natural

Change in the Extent of Glaciers and Glacier Runoff in the Chinese Sector of the Ile River Basin between 1962 and 2012

Change in glacier area in the Kuksu and Kunes river basins, which are tributaries to the internationally important Ile River, were assessed at two different time steps between 1962/63, 1990/93, and
