the survey of climate change impact on drought severity- duration- frequency curves using copulas
climate change has various effects on the quantity of rainfall and warming also is lead to increases in frequency and intensity of droughts by accelerating earth drying up and consequently. it is effective on the curves of severity- duration- frequency of drought (sdf). the purpose of this study is to evaluate the effects of climate change on sdf curves in the future in qareh su basin located i...
متن کاملDerivation of Intensity -Duration-Frequency -Area(IDFA) Curves for Mashhad City
A knowledge of rainfall distribution over a finite area is needed for small bydraulic structures design. Hydrologists have always been concerned about Depth- Area- Duration (DAD) for a specific storm in a watershed. An intense storm occurred on June 6, 1992 which claimed some lives in parts of Mashhad, Khorasan Province, Iran. Data of rainfall depth at 29 raingauge stations around the city and ...

متن کاملA drought frequency formula
The important elements of a drought phenomenon are the longest duration and the largest severity for a desired return period. These elements form a basis for designing water storage systems to cope with droughts. At times, a third element, drought intensity, is also used and is defined as the ratio of severity to duration. The commonly available statistics for the causative drought variables su...
متن کاملAgricultural Drought Frequency, Duration analysis in Karoon 3 Watershed under climate change
The aim of this study is investigation of climate change impact on Karoon3 basin in future periods. For this purpose, the simulated precipitation and potential evapotranspirationof four AOGCM models was used to simulate drought index. Monthly precipitation was calculated by inverse distance weighted method. Reclamation Drought Index (RDI) was used as watershed drought index. RDI was calculated ...
