Study of hydro-climatology at a range of temporal scales is important in understanding and ultimately mitigating the potential severe impacts of hydrological extreme events such as floods and droughts. Using daily in-situ data over the last two decades combined with the recently available multiple-years satellite remote sensing data, we analyzed and simulated, with a distributed hydrologic mode...

The main goal of this study is to use "top-down"? approach to simulate catchment scale hydrologic processes, in terms of water partitioning, runoff generation, storage dynamics and human/water interaction, and therefore to obtain a comprehensive understanding on intra-annual water balance of watersheds. An evaporation model at seasonal scale is developed based on Budyko framework. A runoff gene...

Water resources management requires the knowledge of the environmental conditions and hydrologic processes. The development of Geographic Information Systems (GIS) has allowed the use of spatially and physically based hydrologic models in order to simulate the hydrology in a complicated natural system. It is very important to use such tools especially in regions with limited available data. In ...

[1] Stream hydrology strongly affects the structure of aquatic communities. Changes to air temperature and precipitation driven by increased greenhouse gas concentrations are shifting timing and volume of streamflows potentially affecting these communities. The variable infiltration capacity (VIC) macroscale hydrologic model has been employed at regional scales to describe and forecast hydrolog...

[1] The long-term (1935–1999) monthly records of temperature, precipitation, stream flow, river ice thickness, and active layer depth have been analyzed in this study to examine Lena River hydrologic regime and recent change. Remarkable hydrologic changes have been identified in this study. During the cold season (October–April), significant increases (25–90%) in stream flow and decrease in riv...

The McMurdo Dry Valleys (MDV) of Antarctica are composed of nearly 2000 km of ice-free terrain, supporting a vibrant cold desert ecosystem despite harsh conditions. The ecosystem is largely regulated by the hydrologic cycle within the MDV, which is controlled by climate dynamics. The strength and timing of connections among the hydrologic reservoirs of the MDV (atmosphere, glaciers, soils and p...
