Large flood events in recent years in the state of Wisconsin, USA raised a question of whether high precipitation events are on the rise. The objective of the research was to examine temporal and spatial patterns of extreme precipitation in Wisconsin during 1950–2006. The daily precipitation data used in the study were created by researchers at the University of Wisconsin‐Madison using spatial interpolation of weather stations data across the state to a grid mesh with a spatial resolution of 8 km. For extreme precipitation indices, we calculated 99th, 95th, 90th, 85th, and 80th percentiles of daily total precipitation (>1 mm) in a year and the number of days per year with daily precipitation exceeding 10 mm, 20 mm, and 50 mm. We also conducted the Mann–Kendall test for trend, examined how geographical heterogeneity varied over time, and built quantile regression models for annual summer precipitation. Main findings include the following: the temporal trend of extreme precipitation varied widely across the state; the highest percentile index showed an increasing trend over the largest area, whereas indices of less extreme precipitation tended to generally decrease; extreme precipitation tended to show more dispersed and skewed spatial patterns than annual total precipitation. Overall, indices related to frequency showed more similar spatial and temporal trends to total precipitation than magnitude indices.

“…All the considered rivers are characterised by dam systems for the mitigation of flooding episodes in urbanised areas with potential effects on the analysed ∆Q day values. Thus, for each river drainage basin, we evaluated quantitatively the effects of dam on the streamflow analysis with a statistical approach: concerning the Tiber river, since 1921, (i.e., the starting point of present MED river flow analysis; Table 1) the superposition of flood waves so that the resulting flood waves can be smoothed (Natale and Savi, 2007;Villarini et al, 2011) In the Nemunas river, ice break-up events, rather than rainfall intensities, are the most important controlling factor the discharge rate peaks. Long-term trends indicate that in the nineteenth century, ice cover remain unbroken on average for 30 days longer than in the twentieth century (Stonevičius et al, 2008).…”

Abstract. Volcanic and anthropogenic aerosols, by reflecting solar radiation and acting as cloud condensation nuclei, play a key role in the global climate system. Given the contrasting microphysical and radiative effects of SO2 on rainfall amounts and intensities, the combined effects of these two factors are still poorly understood. Here, we show how concentrations of volcanic sulphate aerosols in the atmosphere, as derived from Greenland ice core records, are strictly correlated with dramatic variations of hydrological cycle in Europe. Specifically, since the second half of the 19th century, the intensity of extreme precipitations in Western Europe, and associated river flood events, changed significantly during the 12–24 months following sulphur-rich eruptions. During the same period, volcanic SO2 exerts divergent effects in central and Northern Europe, where river flow regimes are affected, in turn, by the substantial reduction of rainfall intensity and earlier occurrences of ice break-up events. We found that the high sensitivity of North Atlantic Sea Surface Temperature (SST) and North Atlantic Oscillation (NAO) to atmospheric SO2 concentrations reveals a complex mechanism of interaction between sulphur-rich eruptions and heat exchange between Ocean and atmosphere with substantial impacts on hydrological regime in Europe.

“…The method has received considerable attention in many statistical literatures, but less so in areas related to water resources analysis (Tareghian and Rasmussen 2013). Several studies are reported in generic environmental sciences including analysis of streamflow distributions (Luce and Holden 2009); studying rainfall trend (Mazvimavi 2010); hydrological uncertainty (Weerts et al 2010); and hydro-metrological analysis (Villarini et al 2011). In climatology, the QR method has been used to downscale precipitation data such as Tareghian and Rasmussen (2013).…”

In this paper, we present a study of assessing regional water resources in a highly regulated river basin, the Dee river basin in the UK. The aims of this study include: 1) to address the issue of hydrological simulations for regulated river catchments; 2) to develop a new method revealing the trends of water resources for different scenarios (e.g. dry and wet) and 3) to facilitate water resources assessment under both climate change impacts and regulations. We use the SWAT model to model the hydrological process of the river basin with carefully designed configurations to isolate the impact from the water use regulations and practice. The spatially-distributed model simulations are then analysed with the quantile regression method to reveal the spatial and temporal patterns of regional water resources. The results show that this approach excels in presenting distributed, spatially focused trend information for extremely dry and wet scenarios, which can well address the needs of practitioners and decisionmakers in dealing with long-term planning and climate change impact. The representation of the management practice in the modelling process helps identify the impact from both climate change and necessary regulatory practices, and as such lays a foundation for further study on how various management practices can mitigate the impact from other sources such as those from climate change. The novelty of the study lies in three aspects: 1) it devises a new way of isolating and representing management practice in the hydrological modelling process for regulated river basins; 2) it integrates the QR technique to study spatial-temporal trends of catchment water yield in a distributed fashion, for wet and dry scenarios instead of the mean; 3) the combination of the methods are able to reveal the impacts from various sources as well as their interactions with catchment water resources.
