Frequency analysis of rainfall data is essential in the design and modelling hydrological systems but often statistically limited by total observation period. With advances weather radar technology, frequency areal possible at a higher spatial resolution. Still, periods are short relative to established rain gauge networks. A stochastic framework, “stochastic storm transposition” shows great pr...

Spatial variability of both long and short term rainfall in an urban environment in Malaysia was studied using historical monthly and yearly rainfall data and, unique for the humid tropics region, recently collected, short term rainfall data measured with very small time and space resolution. The results for the yearly data indicated some elongation of the spatial structures of rainfall in the ...

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract Several hydrological analyses need to be founded on a reliable estimate of the design storm, which is the expected rainfall depth corresponding to a given duration and probability of occurrence, usually expressed in terms of return period....

Changes in the hydrologic cycle due to increase in greenhouse gases cause variations in intensity, duration, and frequency of precipitation events. Quantifying the potential effects of climate change and adapting to them is one way to reduce urban vulnerability. Since rainfall characteristics are often used to design water structures, reviewing and updating rainfall characteristics (i.e., Inten...

The release of arsenic from wood pressure-treated with chromated copper arsenate (CCA) can be decreased by application of wood finishes, but little is known about the types of finishes that are best suited for this purpose. This study evaluated the effects of finish water repellent content and ultraviolet (UV) radiation on the release of arsenic, copper, and chromium from CCA-treated wood expos...

An increase in the occurrence of sudden local flooding of great volume and short duration has caused significant danger and loss of life and property in Korea as well as many other parts of the World. Since such floods usually accompanied by rapid runoff and debris flow rise quite quickly with little or no advance warning to prevent flood damage, this study presents a new flash flood indexing m...

Abstract Fine-scale characteristics of summer precipitation over Cang Mountain, a long and narrow mountain with quasi-north-south orientation in Southwest China, are studied based on station radar data. Three kinds rainfall processes classified according to the initial stations regional events (RREs) by utilizing minute-scale rain gauge RREs initiating western part Mountain exhibit eastward evo...
