In view of the results of the substantial past Walocalized increases in heavy rain events on the order ter Survey research on the effects of urban environof 10 to 25% in both incidence and magnitude. ments on the incidence and magnitudes of heavy rainstorms, it was considered necessary to assess and incorporate (if feasible) urban effects on the frequency distributions of heavy rainfall in Illi...

This study aims to reveal rainfall anomalies and changes over the Yellow River Basin due to the fragile ecosystem and rainfall-related disasters. Common trend analyses relate to overall trends in mean values. Therefore, we used two graphical methods: the quantile perturbation method (QPM) was used to investigate anomalies over time in extreme rainfall, and the partial trend method (PTM) was use...

The distributed lag model (DLM), used most prominently in air pollution studies, finds application wherever the effect of a covariate is delayed and distributed through time. We specify modified formulations of DLMs to provide computationally attractive, flexible varying-coefficient models that are applicable in any setting in which lagged covariates are regressed on a time-dependent response. ...

Landslide in alpine regions often causes heavy losses of both human lives and properties, most of the landslides are induced by heavy rainfall. In this paper, we put forward an early warning system of rain-induced landslide. From 2002, we carried on the demonstrative work of landslide monitoring and early warning in Yaan, Sichuan Province, China, and constructed the first county-scale landslide...

This paper considers the potential impact on human health from waterborne and vector-borne infections. It concentrates on the impact of two possible changes to climate; increased frequency of heavy rainfall events, with associated flooding and increased temperature. Flooding is associated with increased risk of infection in developing nations but not in the West unless water sources are comprom...

over the past decades, the fallout radionuclides 137cs, 210pbex and 7be are increasingly being used to quantify soil erosion and sedimentation rates. although studies using 137cs and to some extent 210pbex are now well-documented, there is a need for further work aimed at exploring the use of 7be, particularly in arid and semi-arid areas. investigating soil erosion processes occurring over shor...
