Annual series of three stochastic rainfall model parameters — the seasonal wet day amount (or intensity), the conditional dry–day probability (or dry–spell persistence), and the conditional wet-day probability (or wet-spell persistence) — were examined using daily rainfall records for ten UK stations for the period 1901–1995. The purpose was first, to determine the extent to which these indices...

The erosional response of calcareous soils along a climatological gradient in Alicante, SE Spain was studied. The erosional response was defined in terms of indicators obtained from field rainfall simulation experiments and laboratory studies of soil aggregation. Measurements were made at seven sites on limestones and marls between Benidorm with an y1 Ž y1. annual average rainfall of 400 mm yr ...

background: the municipal waste landfill sites have high a potential of contaminating the ‎ environment and having effects of the human health due to waste degradation, production of leachate, carbon dioxide and ‎ methane gases. the present study aims to evaluate the location of the solid waste landfill using gis and based on the oleckno index. assessment parameters included average annual rain...

This paper reports on variation in leaf area index (L) in five Eucalyptus globulus Labill. plantations in response to application of nitrogen, thinning at age 2 years and variation in climate wetness index (the ratio of rainfall to potential evaporation). Observed L is compared with: (i) L predicted to optimize net primary productivity for a given average annual temperature, annual water use an...

In this paper, the variation of temperature and rainfall at Patna are analysed using simple non-parametric tests. The trends in annual maximum minimum daily temperatures, rainfall, number rainy days a year, average per day ratio to have been examined. Tends total monthly Highest month also determined for every year. data Mann-Kendall test indicated statistically significant changes pattern city.
