The impact of climate change and glacier mass loss on the hydrology in the Mont-Blanc massif
Assessment of climate change impacts on water resources of the Purus Basin in the southwestern Amazon. Knowledge about water resources is critical for climate adaptation in face of long-term changes and more frequent extreme events occurrence. During the major droughts of and , a large epicenter was located in the southwestern Amazon over the Purus River Basin. In this sense, we conducted a hydrological simulation in this basin to assess the climate change impacts on its water resources throughout the 21st century. The consequences of projected climate change are severe and will probably have a great impact upon natural ecosystem maintenance and human subsistence. In a climate change adaptation process, the preservation of the natural forest cover of the Purus Basin may have great importance in water retention.
Hydrological impacts of climate change on a data-scarce Greek catchment
Conceived and designed the experiments: SHM. Wrote the paper: SHM. The hydrological response to land cover changes induced by human activities in arid regions has attracted increased research interest in recent decades. The study reported herein assessed the spatial and quantitative changes in surface runoff resulting from land cover change in the Al-Baha region of Saudi Arabia between and using an ArcGIS-surface runoff model and predicted land cover and surface runoff depth in using Markov chain analysis. Land cover maps for and were derived from satellite images using ArcGIS
Journal of Water and Climate Change 1 March ; 10 1 : 63— The changing climate has raised significant concerns for water resources, especially on a watershed scale. In this study, the downscaled global circulation model GCM products were further bias corrected and evaluated for the period of — The results of this study show: 1 the Parameter—elevation Regressions on Independent Slopes Model PRISM products offer a reliable replacement for limited observations for bias correction using quantile mapping QM technique; 2 average increases of 2. For management of local water resources, this study provides a better understanding of variations in the streamflow rate and timing to a potential climate change in the study area as well as corresponding uncertainties in the estimation processes. Global water circulation makes atmosphere and hydrology closely interact with fluxes of water and energy, which has immediate and long-term effects on water systems. Precipitation and temperature — two principal meteorological drivers of surface hydrology — significantly affect the volume and timing of streamflow Sagarika et al.

Hydrologic Impacts of Ensemble-RCM-Projected Climate Changes in the Athabasca River Basin, Canada
Climate change has significant implications on water resources and freshwater ecosystems Eum et al. Regional climate models RCMs and macroscale hydrologic models MHMs are common approaches to investigate the effects of projected climate changes on local hydrological regimes. RCMs are able to simulate detailed regional atmospheric and terrestrial processes Denis et al. The Athabasca River is the longest undammed river in the Canadian Prairies, and the potential effects of climate change on its hydrological cycles have been implicated for water scarcities, wild fires, flooding, and droughts Cheng et al.
This paper demonstrates a climate change impact study on the hydrological process of a data-scarce Greek watershed. The ERA-Interim reanalysis climate data regarding the period from to were used for the historical simulation of the watershed. The ArcSWAT simulated data were evaluated against the observed discharge data for the periods with the available data. Based on the results, the increase in the minimum and the maximum temperature contributed to an increase in the actual evapotranspiration and the surface runoff. In contrast, the temperature increase caused a reduction in the infiltration. An increase reduction in the precipitation led to an increase reduction in the hydrological components. The climate change impact analysis of the Greek watershed showed that not only the precipitation changes but the temperature changes as well directly influence the water balance components of the research area and particularly the infiltration.
Wetlands are globally important ecosystems that provide critical services for natural communities and human society. Montane wetland ecosystems are expected to be among the most sensitive to changing climate, as their persistence depends on factors directly influenced by climate e. Despite their importance and climate sensitivity, wetlands tend to be understudied due to a lack of tools and data relative to what is available for other ecosystem types. Here, we develop and demonstrate a new method for projecting climate-induced hydrologic changes in montane wetlands. Using observed wetland water levels and soil moisture simulated by the physically based Variable Infiltration Capacity VIC hydrologic model, we developed site-specific regression models relating soil moisture to observed wetland water levels to simulate the hydrologic behavior of four types of montane wetlands ephemeral, intermediate, perennial, permanent wetlands in the U. Pacific Northwest.

Special issue: Water, ecosystem, cryosphere, and climate data from the interior Data description paper 19 Mar Cold region hydrology is very sensitive to the impacts of climate warming. Impacts of warming over recent decades in western Canada include glacier retreat, permafrost thaw, and changing patterns of precipitation, with an increased proportion of winter precipitation falling as rainfall and shorter durations of snow cover, as well as consequent changes in flow regimes. Future warming is expected to continue along these lines. Physically realistic and sophisticated hydrological models driven by reliable climate forcing can provide the capability to assess hydrological responses to climate change.
