in this paper we present a method to perform flood frequency analysis (ffa) when the assumption of stationary is not important (or not valid). a wavelet transform model is developed to ffa. a full series is applied to ffa using two different wavelet functions, and then a combined method is investigated. in the combined method, all discharge data which were less than the lowest value of annual m...

Despite general agreement that river-valley hydrology shapes riparian ecosystems, relevant processes are difficult to distinguish and often inadequately specified in riparian studies. We hypothesize that physical constraints imposed by broad-scale watershed characteristics and river valleys modify local site conditions in a predictable and probabilistic fashion. To test this hypothesis, we empl...

[1] It is widely acknowledged that climate variability modifies the frequency spectrum of extreme hydrologic events. Traditional hydrological frequency analysis methods do not account for year to year shifts in flood risk distributions that arise due to changes in exogenous factors that affect the causal structure of flood risk. We use Hierarchical Bayesian Analysis to evaluate several factors ...

Abstract Flood is one of the most common natural disasters, which also triggers other disasters such as erosion and landslides. damage can be minimised by ensuring optimum design drainage infrastructure flood management tasks, depends largely on reliable estimation quantiles. This study investigates quantile in ungauged catchments using a kriging-based regional frequency analysis (RFFA) techniq...

Global warming is currently of great concern. Yet the ecological effects of low-frequency climate variations remain largely unknown. Recent analyses of interdecadal variability in population abundance of the Oriental migratory locust (Locusta migratoria manilensis) in China have revealed negative associations with temperature and positive associations with Yangtze drought and flood frequencies ...

To reduce flood damage in the face of increasing frequency and intensity extreme rainfall events, it is necessary to implement linkages between hazard countermeasures resilient community development. This paper introduces an example analysis climate change impact on discharge Japan discusses predictions risk assessment for flood-resistant regional
