1. Introduction The Mackenzie River basin (MRB) is one of the world’s largest high-latitude river basins and covers an area of approximately 1.8 million km 2 ( Fig. 1 ). In this paper, we focus our attention on three extreme rainfall events (with rainfall exceeding 100 mm) that occurred over the southern MRB between 1993 and 2001: 22–23 June 1993, 18–19 June 1996, and 28–29 July 2001. The southern MRB encompasses the Peace River and Athabasca River basins, and covers an area of approximately

ability to represent glacier melt and runoff production for a glacierized catchment. In this paper, based on the combination of observed data and simulations, we analyze glacier variation and the response of hydrological processes in a typical glacierized catchment of the central Tian Shan during recent decades. We then project the potential change of the response of the hydrologic processes to future climate scenarios. 2. Description of study area The study area of the Kunma Like River basin (one of

1. Introduction The Menomonee River, which drains much of the Milwaukee metropolitan region ( Fig. 1 ), experienced record flooding 21 June 1997 and 6 August 1998. Sample flood frequency distributions ( Fig. 2 ) for the Menomonee River at Wauwautosa [319 km 2 ; U.S. Geological Survey (USGS) gauge number 04087120] and its tributaries Underwood Creek (47 km 2 ; USGS gauge number 04087088) and the Menomonee River at Menomonee Falls (90 km 2 ; USGS gauge number 04087030) illustrate the magnitudes

1. Introduction Discharge from northern-flowing rivers is the primary freshwater source to the Arctic Ocean. Studies show that both the amount and the timing of freshwater inflow to the ocean systems are important to ocean circulation, salinity, and sea ice dynamics ( Aagaard and Carmack 1989 ; Macdonald 2000 ; Peterson et al. 2002 ). Climate over Arctic regions has experienced significant changes during the past few decades. For instance, climate changes over Siberian regions include

1. Introduction The Jordan River, flowing from the Mount Hermon area to the Dead Sea, is the most important freshwater system in the region, and its water is almost fully used by withdrawal from Lake Kinneret, fed to a large extent from the upper Jordan River (UJR) basin. As the countries in the eastern Mediterranean (EM) region show high rates of growth of population and urbanization, the current scarcity of water is expected to worsen in the future, with the additional pressure on the water

al. 2000 ; Xiong et al. 2010 ). Meeting the demand for water for agricultural, domestic, and industrial purposes from limited water resources is likely to be a challenge for the future. In China, river flow makes up ~80% of water consumption and is thus the main water source for human society. Especially in the context of climate change, this creates an urgent need to quantify and understand the factors that contribute to changes in river flow and allow water planning and management of China to

. Brubaker et al. (2001) showed the long-term analysis of evaporative sources for the Mississippi River basin (MRB). Variations of evaporative oceanic sources can affect the recycling of precipitation. In addition, over 36 years some significant trends in sources of water for the basin were identified. Second, Bosilovich et al. (2005) evaluated climate atmospheric general circulation model (AGCM) simulations for a 50-yr duration. The AGCMs show global increasing trends of precipitation, but the trend

1. Introduction The Colorado River spans seven states in the western United States and is a leading provider of water for municipal use, agriculture, and power in the Southwest. In the face of the warming climate, numerous papers have warned about sizable water shortages of the Colorado River ( Barnett and Pierce 2008 , 2009 ; Christensen et al. 2004 ; McCabe and Wolock 2007 ; Rajagopalan et al. 2009 ). In 2013, the Bureau of Reclamation (BOR) released a comprehensive Colorado River Basin

1. Introduction Climatologically, the mei-yu season over the Yangtze–Huai Rivers basin (YHRB; Fig. 1b ) in east-central China from mid-June to mid-July is one of the three heavy rainfall periods in China. The other two are the early summer rainy season from mid-May to mid-June over south China and the summer rainy season in north-northeast China after mid-July (e.g., Ding 1992 ). This intraseasonal variation exhibits sharp northward shifts among the three regions, which are associated with

1. Introduction The presence of a seasonal snowpack in western Canada forms an essential component of its regional water resources and also serves as a sensitive indicator of climate change. Peak flows of the Fraser River of British Columbia (BC) and its many tributaries usually occur in late spring and early summer and are driven by snowmelt, especially at high elevations ( Moore and Wondzell 2005 ). The Fraser River basin (FRB) is a snow-dominated system ( Morrison et al. 2002 ), but
