During the past few decades, the southern part of the Caspian Sea has more frequently experienced extreme climatic events such as drought and flood. Trend analysis of hydro-climatic variables was conducted using non-parametric Mann-Kendall test and regression test for Neka basin in the north of Iran. Trends of precipitation and stream flow characteristics including maximum flow, mean flow...
Aureobasidium pullulans is ubiquitous, polymorphic and black fungus producing a variety of important metabolites including enzymes, polysaccharides and single cell protein. It is considered as a probable source for antagonistic activity against a number of phytopathogenic fungi and possible biocontrol agent of post harvest diseases. The present work aims at the antibacterial compounds produced ...
The purpose of this study was to analyze the effect spillway width on flow elevation at weir crest based flood discharge design for Probable Maximum Flood (PMF) return period using routing hydrologically Cacaban Dam (Indonesia). rainfall Precipitation (PMP) uses Hershfield Equation. analysis QPMF used Nakayasu Synthetic Unit Hydrograph (HSS). hydrologic method. is located in Jati Village, Kedun...
abstract the climate change was known to force local hydrology, through changes in the pattern of precipitation, temperature and the other hydrological variables. in this research, the impact of global warming on maximum and minimum temperature, precipitation and evapotranspiration (wheat, corn, tomato and sugar beet) of kashafrood basin under two climate change scenarios (a2 and b2), and the o...
Climate change, with effects on temperature and rainfall, has a great influence on dry period. Therefore, it is very important to study this phenomenon in the analysis of dry period length. In this study, we used GFDL-ESM2M and four RCP scenarios to simulate precipitation, maximum and minimum temperature and used CCT with statistical methods to downscale the results. The data used in this study...
Although precipitation interannual variability is projected to increase due to climate change, effects of changes in precipitation variance have received considerable less attention than effects of changes in the mean state of climate. Interannual precipitation variability effects on functional diversity and its consequences for ecosystem functioning are assessed here using a 6-year rainfall ma...
precipitation is one of important parameters of climatology and atmospheric science that have more importance in human life. recently, extensive flood and drought entered many damage to most parts of the world. precipitation forecasting and alerts management role is responsible for these problems. today, artificial neural networks are one of developed method that applied for estimate and predic...
Global precipitation data sets with high spatial and temporal resolution are needed for many applications, but they were unavailable before the recent creation of several such satellite products. Here, we evaluate four different satellite data sets of hourly or 3-hourly precipitation (namely CMORPH, PERSIANN, TRMM 3B42 and a microwave-only product referred to as MI) by comparing the spatial pat...
Climate change is a phenomenon has been based on the available evidence from a very long time ago and now its existence is very probable. The speed and nature of climate parameters changes at the middle of twentieth century has been different and its quickness more than the before and its trend changed to some extent comparing to the past. Climate change issue now regarded as not only one of th...
The purpose of this research was to investigate the trend of annual changes in Yazd stationchr('39')s meteorological parameters including minimum and maximum average daily temperature and average daily precipitation (1961-2005), as well as the predicted annual mean of these parameters in the three upcoming thirty years of the 2040s, 2070s and 2100s, by the SDSM model, under RCP2.6, RCP4.5, RCP8...
