A comprehensive model strategy is presented which enables the prediction of catchment hydrology and the dynamics of sediment transport within the alluvial river systems draining these catchments. The model is driven by AGCM-based weather predictions, generalised by using a stochastic weather generator, and by palaeo-climate and palaeo-environment reconstructions. The model consists of a lumped ...

Study of climatic condition has been an active c h a l l e n g i n g research area in scientific community. During last decade the concern of global warming has attracted attention not only of the scientists but also of common people. In the current scenario each and every individual is concerned about the changing climatic conditions and interested in knowing daily weather conditions to unders...

In consideration of the steady entanglements of viticulture with the environmental features – including climate – it is of concern to project which climatic conditions an area is expected to face in a changing climate scenario. A quantitative approach helps in assessing class shift in climate classification; both “generic” climatic and bioclimatic indices were considered in this study, namely: ...

parameters recognize different area weather and climatic and effect on the plants one of the best important effect elements is increase products yield. agro climatic study can state area ability and maximum exploit its. the aim of this research is, recognizing of the ability ecologic potential in different areas for cultivating brassica napus in regard to climatic temperature needs in khorasan ...

Climate change  is one of the most important challenges in recent years. Heavy flood, hot weather, early coldness, most of drought replications, risen of sea water level, pests and plant disease ,reducing of ozone layer thickness, global worming ,and melting ices, are cases that introduced climate change issue in recent decades more. Climate is one of the most important  factors for crop  chang...

Glacier National Park served as a test site for ecosystem analyses that involved a suite of integrated models embedded within a geographic information system. The goal of the exercise was to provide managers with maps that could illustrate probable shifts in vegetation, net primary production (NPP), and hydrologic responses associated with two selected climatic scenarios. The climatic scenarios...

The goal of this research is the determining of planting date and providing agricultural calendar for corn in Kermanshah province using climatic elements of temperature and rain fall. so, at first, long term  climatic statistics are collected from 2001 to 2011  and then  considered to temperature and rain fall parameters like  absolute maximum and minimum  in region during growth period, planti...

SYNOPSIS. Some of the accumulated knowledge on the complex problems involved in the transmission of helminths of domestic animals in the USA is summarized. The lollowing conditions are usually necessary for the development outside the final hosts of infective stages of these helminths: moderate temperatures, adequate moisture, oxygen, and protection from freezing, desiccation and direct sunligh...

The ionospheric plasma can significantly influence the propagation of radio waves and the ionospheric disturbances are capable of causing range errors, rapid phase and amplitude fluctuations (radio scintillations) of satellite signals that may lead to degradation of the system performance, its accuracy and reliability. The cause of such disturbances should be sought in the processes originating...
