Abstract The flood regimes have been changing due to the climate change and human activities. Evaluating risk under nonstationarity is critical water resource management authorities in disaster reduction. In this study, annual maximum streamflow (AMS) was used analyze frequency Hanjiang River (HJR) Basin. A Generalized Additive Model for Location, Scale Shape (GAMLSS) employed characterize AMS ...

از آنجا که سامانه های انسانی مانند کشاورزی و صنعت، که وابسته به عناصر آب وهوایی هستند، بر مبنای ثبات و پایداری اقلیم طراحی شده و عمل می نمایند، ضروری است تغییرات بلندمدت دما و بارش، شناسایی و مدنظر قرار گیرند. در صورتی که داده های ایستگاهی بلندمدت موجود باشند؛ روش آماری، مناسب ترین روش برای ریزگردانی است. تعیین بهترین روش آماری برای ریزگردانی در یک منطقه از پیش مشخص نیست و نیازمند بررسی توانمند...

This study presents an evaluation of climate and land-use changes induced impacts on water resources Multan City, Pakistan. Statistical Down Scaling Model (SDSM) Geographical Information System (GIS) are used for change scenario spatial analyses. Hydrologic Engineering Center’s Hydraulic Modeling (HEC-HMS) model is rainfall-runoff simulation. The investigated results show significant in climato...

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...

Abstract In this study, the artificial neural network (ANN) method was applied to investigate impacts of climate change on water quantity and quality Qu'Appelle River in Saskatchewan, Canada. First, second-generation Canadian earth system model (CanESM2) adopted predict future conditions. The Statistical DownScaling Model (SDSM) then downscale generated data. To analyze river, concentrations di...
