Climatic parameters in time and space scales of change are for many reasons of Changes and how they should be based on observations using a statistical method to be determined. Analysis of the most widely used statistical methods that assess potential climate change on hydrological time series, such series of precipitation, temperature and flow rate used. This study of 11 synoptic,rain gage and...

The trend analysis of annual temperature (daily average) and total precipitation has been conducted for 14 stations located in the Aegean Region, Turkey. Sen, Spearman’s rho, Mann-Kendall test methods are used detection historical trends region. Pettitt is also implemented to find significance trend, while Theil-Sen approach applied detect change point(s) time series. Findings following study i...

İklim değişikliği, kuraklık gidişinin alansal ve zamansal yayılımının izlenmesinde farklı yaklaşımları ortaya konarak analitik çözümlemeleri ihtiyaç haline getirmiştir. Güneydoğu Anadolu Projesi (GAP) kapsamında; 19 242 km²’lik büyüklüğü ile sulama alanlarının %50’sine sahip Şanlıurfa’da yürütülen bu çalışmada, yöntemler kullanılarak meteorolojik kuraklığın alansal-zamansal eğiliminin büyüklüğü...

the aim of this study was the analysis of discharge variations of two rivers i.e. qezelozan and shahroud, regarding the sustainable rice production in guilan province. to achieve this purpose four trend analysis tests including sen, mann-kendall, linear regression and spearman were used. in this study, river discharge data of 49 and 37 years for respectively qezelozan and shahroud rivers were u...

abstract: the dust is one of the weather phenomena that have negative environmental effects and consequences. the central city of ahvaz in khuzestan province is one of cities that in every year witnessed the dust in its environment. in this study, after determining that the dust phenomena data are abnormal, using the sen's nonparametric model been proceed to modeling of changes and survey ...

Streamflow is an important factor in the study of water resource management, floods, and droughts. Dramatic climate change has created extreme rainfall distributions, making the study of streamflow trends and variability even more crucial. In this study, the long-term streamflow data and trends recorded at gauging stations in Northern Taiwan are analyzed using the Mann-Kendall test. The data us...

abstract recent global warming has led to a change in the global hydrological cycle and an increase in extreme events such as flood and drought at the global and continental scales. however, at the regional scale, the magnitude of warming and the resulting changes in water resources are different from one region to another. unlike air temperature whose increase is evident throughout the world, ...
