I Introduction By linking climatic variations with the fundamental biological requirement of water availability , drought is a primary topic within applied climatology. Drought acts as a unifying climatological approach that provides valuable information for agricultural, ecological, and hydrological applications. While a lack of water is straightforward to comprehend and appreciate, a wide arr...

Based on Coupled Model Intercomparison Project Phase 5 (CMIP5) dataset and a variable infiltration capacity (VIC) hydrological model, this study assesses the possible influence of climate change in the upstream region of the Yangtze River on droughts in the future 30 years. Long-term daily soil moisture content were simulated by VIC model at a 50 km × 50 km resolution from 1951 to 2013. Regiona...

Accurate terrestrial water storage (TWS) estimation is important to evaluate the situation of the water resources over the Yangtze River Basin (YRB). This study exploits the TWS observation from the new temporal gravity field model, HUST-Grace2016 (Huazhong University of Science and Technology), which is developed by a new low-frequency noise processing strategy. A novel GRACE (Gravity Recovery...

[1] In this paper, we investigate floods and droughts in the Upper Mississippi basin over a 50-year period (1950–1999) using a hydrological model (Variable Infiltration Capacity Model – 3 Layer). Simulations have been carried out between January 1950 and December 1999 at daily timestep and 1/8 spatial resolution for the water budget and at hourly time-step and 1 spatial resolution for the energ...

Stream and riparian groundwater hydrology has been studied in a small intermittent stream draining a forested catchment for a system representative of a Mediterranean climate. The relationship between precipitation and stream runoff and the interactions between stream water and the surrounding riparian groundwater have been analysed under a wide spectrum of meteorological conditions. The hypoth...

Repeated observations in the North Pacific subtropical gyre near Hawaii reveal pronounced freshening (--0.15 psu) and cooling (--0.5øC) of the upper thermocline from 1991 through 1997. The freshening appears progressively later on deeper isopycnals consistent with subduction of surface salinity anomalies at higher latitudes and subsequent southward advection. Winter rainfall anomalies in the ce...

The ongoing debate on water policies in Spain is characterised by a traditional paradigm, dominated by the intervention on hydrological systems through the construction and management of infrastructure, which is progressively being abandoned but is currently still strong while the emergence of new management approaches. Climate change and the Water Framework Directive (WFD) are, in addition, th...

The Mikkes basin is located at the north centre of Morocco. The yearly approach of the P<2T ratio reveals a very bad monthly distribution of precipitations and a seasonal drought which is apparently observed well after the Eighties era. The extent of the drought can be shown clearly by the strong deficit of the river between the periods 1970-1979 and 1980-2000 which is considerable with around ...
