Design of water infrastructures requires estimation of design flow which is the runoff that an infrastructure can handle safely. For estimation of this design flow, rainfallrunoff modelling is widely adopted. Temporal pattern (the distribution of rainfall depths over sub-storm durations) is considered to be one of the most critical input variables in the rainfall-runoff modelling. Design tempor...
1. The importance of rainfall is recognized in arid habitats, but has rarely been explored in ecosystems not viewed as rainfall limited. In addition, most attempts to study how rainfall affects organismal survival have focused on long-term rainfall metrics (e.g. monthly or seasonal patterns) instead of short-term measures. For organisms that are short lived or are sensitive to desiccation, shor...
Splash (raindrop) erosion plays an significant role in soil loss, especially in arid and semi-arid regions with poor vegetation. In this paper, by analyzing the pattern of rainfalls that occurred during 26 years in four basins located in Semnan County, their effect on the pattern of eroded sediments from the basin was investigated. Sedimentary layers from the sampling of retarding reservoir sed...

In many semi-arid environments, vegetation is self-organised into spatial patterns. The most striking examples of this are on gentle slopes, where striped patterns are typical, running parallel to the contours. Previously, Klausmeier [1999. Regular and irregular patterns in semiarid vegetation. Science 284, 1826-1828.] has proposed a model for vegetation stripes based on competition for water. ...
Studies on vegetation geographical distribution patterns are often associated with the causal factors such as rainfall, soils or temperature patterns. Reasonably accurate and reliable maps of the climatic and edaphic factors are not always readily available, and when they are, their usefulness in biogeographical investigations is constrained by the quality of the data. Variability of rainfall i...
Classifying daily climate circulation patterns has always been considered by climatologists. Investigating climate changes such as rainfall and the temperature in a same single time and place suggests that these changes are strongly influenced by atmospheric circulation patterns. Regarding so, climate changes, known as variables here, such as rainfall, temperature, and other related phenomen...
The relationship between the incidence of norovirus-associated gastroenteritis outbreaks (NAGOs) in Victoria, Australia for the period 2002-2007 and rainfall was examined. Statistical analysis involving the correlation between time series indicated that there was a statistically significant (p < 0.05) correlation between monthly NAGO incidence and average monthly rainfall. There was a lag of an...
Diurnal Variability of Tropical Rainfall Retrieved from Combined GOES and TRMM Satellite Information
Recent progress in satellite remote-sensing techniques for precipitation estimation, along with more accurate tropical rainfall measurements from the Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI) and precipitation radar (PR) instruments, have made it possible to monitor tropical rainfall diurnal patterns and their intensities from satellite information. One year (August 1998...
