Investigation of the precipitation phenomenon as one of the most important meteorological
factors directly affecting access to water resources is of paramount importance. In this study …

The aim of this study was to analyse spatial and temporal homogeneity and trends in
seasonal and annual precipitation and their fluctuations during 1957–2016 in Iran. For …

Abstract Although the Urmia Lake has undergone remarkable drought conditions within the
past decades mainly due to climate change, drought studies covering the entire Urmia Lake …

In this study, the trend of precipitation and river flow rate changes in Lake Urmia basin (LUB)
were investigated at two monthly and annual scales using the modified Mann-Kendall test …

Human activities and climatic changes have caused severe changes in hydrological values
in recent decade. On the other hand, extreme values such as those of flood have non …

Investigation of precipitation characteristics on daily, monthly, and annual time scales can
contribute to gaining important information related to temporal and spatial distribution of …

Trend analysis of reference evapotranspiration (ET 0), as a key factor in irrigation
programming, has an important role in water resources management. Many parameters …

The behavior of hydrological processes is periodic and stochastic due to the influence of
climatic factors. Therefore, it is crucial to develop the models based on their periodicity and …

Temporal changes of meteorological variables can affect reference evapotranspiration (ET
0). The goal of the present research is to analyze the changes of ET 0 and identify the impact …

The spatial variability of precipitation was investigated in the northwestern corner of Iran
using data collected at 24 synoptic stations from 1986 to 2015. Principal component analysis …
