a methodology is presented for the stochastic generation of daily rainfall which accounts for changes to the climatic inputs. the focus of the study is an example catchment in iran. the methodology addresses the inability of gcms to provide suitable future scenarios for the time and space scales required for a water resource impact assessment for a small catchment. one stochastic model for rain...

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...

The country's economy is dependent on many variables that play a role in growth and development of the country. There are many variables in the economy that effect on country's economy. On the other hand rainfall is one of important factor of climate change that affected on economic strategic programs such as agriculture sector programs. Rainfall Changes effect on many economic variables that i...

the zoning of phenomena based on geographical location has a long history; any geographical zone is a part on ground level, which possesses noticeable internal consistency in terms of its existing phenomena and processes. agroclimatic zoning is mainly purposed to determine agroclimate regions and to evaluate these zones based on their relative utility in order to cultivate varieties of agricult...

rainfall is recognized as one of the main triggering factors of landslides. researchers have long attempted to determine the amount of precipitation required to trigger slope failures. one of the landslide zones in iran is chaharmahal & bakhtiari province where many landslides cause high casualties in recent decades. it is significant that most of these landslides occur after a rainy period...

In this study a new conceptual model for partial duration series analysis was applied to determine the likely rainfall of the monsoon season and the pattern of rainfall events distribution. Example case study was carried out with rainfall data of semiarid area, Agra, India, experiencing extremes of yearly rainfall; ranging between high (1200 mm) to low (300 mm). The coefficient values for the e...
