چکیده
This study analyzed the multivariate flood risk for river Thames at Kingston based on historical data from National River Flow Archive (NRFA) website. The bivariate analysis framework was prepared joint return periods of peak flow (m3/s) and 3-day annual maximum pair. A total 137 samples pairs 1883 to 2019 were adopted analysis. characterized depending quantification frequency pair through copulas methods. unknown parameter each copula estimated using method-of-moment (MOM) estimator Kendall’s tau inversion, in which Clayton performed best model dependence two variables. Then, hydrologic period AND, established method. results reveal that would keep a constant value some time then moderately decrease as AMAX increases 700 m3/s. indicator under four service scenarios three flows whose positioned 50, 100, 150 years. outcomes can be used decision support during design defenses hydraulic facilities.

Modelling metaldehyde in catchments: a River Thames case-study.
The application of metaldehyde to agricultural catchment areas to control slugs and snails has caused severe problems for drinking water supply in recent years. In the River Thames catchment, metaldehyde has been detected at levels well above the EU and UK drinking water standards of 0.1 μg l-1 at many sites across the catchment between 2008 and 2015. Metaldehyde is applied in autumn and winter...
متن کاملInvestors' Perception of Bank Risk Management: Multivariate Analysis Techniques
According to the nature of their activities, banks are exposed to various types of risks. Hence, risk management is at the heart of financial institutions management. In this study, we intend to summarize the information content of bank financial statements on diverse risks faced by banks and then determine how stock markets react to bank's risk management behavior. The methodology used in this...
متن کاملHydrologic Variability of the Cosumnes River Floodplain
Natural floodplain ecosystems are adapted to highly variable hydrologic regimes, which include periodic droughts, infrequent large floods, and relatively frequent periods of inundation. Effectively managing water resources and maintaining ecosystem services provided by floodplains—and associated aquatic, riparian, and wetland habitats—requires an understanding of seasonal and inter-annual hydro...
