We exploit El Niño–Southern Oscillation (ENSO) indices and moist static energy of surface air over the Indian subcontinent and surroundings as predictors of monsoon rainfall over India during early and late seasons, defined here as 20 May to 15 June and 20 September to 15 October, respectively. Although these seasons contribute only ~22% of the entire seasonal rainfall, they clearly affect plan...

The cleaning effect of heavy rain (the rainfall reaches 5 mm every day) on surface contamination of insulators is more effective than dew, fog, mist, and other light rain conditions which can initiate leakage currents and increase the likelihood of flashover. It is well understood that heavy rain can wash away contamination from the surface of high voltage (HV) insulators and thereby reduce the...

the economic growth and development programs in iran call for particular attention for environmental quality control and protection through designing proper sewage treatment and disposal. to design such system, 'the frequency analysis of rainfall is required for the estimation of quantities of flows. there are few places in iran, with adequate rainfall data to permit frequency analysis, an...

Soil erosion is a global challenge, seriously threatening soil and water resources andenvironmental qualities. One of the important factors to consider in the process of runoffgeneration and soil erosion is the physical and chemical properties of soils under differentland-uses. The aim of this study is to estimate soil erosion and runoff in rangeland, rain-fedand abandoned rain-fed agriculture ...

splash detachment and transport of soil particles by raindrops are the initiating mechanisms of soil erosion by water. the size distribution of splashed particles is very important and effective in the rate of other erosion processes. however, this important issue has been less considered. therefore, the present study investigated individual and interaction effects of slope, rainfall intensity ...

This paper presents rainfall erosivity values derived from a 7-year rainfall recording in the Cape Verde islands, Central East Atlantic. The data set consisted of 63 storm events, continuously registered in 15-min intervals. Kinetic energy of storm rainfall corresponded to established values in other tropical locations. Two algorithms to estimate erosivity, expressed as energy times intensity, ...

Ecohydrology. 2017;10:e1813. https://doi.org/10.1002/eco.1813 Abstract The use of green infrastructure for reducing stormwater runoff is increasingly common. One under‐studied component of the green infrastructure network is the urban forest system. Trees can play an important role as the “first line of defense” for restoring more natural hydrologic regimes in urban watersheds by intercepting r...

In this work, the multifractal properties of hourly rainfall data recorded at a location in Southern Spain have been related to the scale properties of the corresponding intensity–duration–frequency (IDF) curves. Four parametric models for the IDF curves have been fitted to the quantiles of rainfall obtained using the generalized Pareto frequency distribution function with the extreme data seri...

To determine the prevalence and seasonal variation of Psoroptes ovis (Delafond, 1858) mange in goats in the semiarid region of Paraíba, 541 crossbred goats of both sexes and different ages were examined between June 1999 and May 2001 and between August 2011 and December 2012, by washing their ear canals. The monthly prevalence of the infestation varied between 66.66% and 100% without significan...
