introduction identification and analysis of time-series behavior of the climatic elements and processes upon them are the basic factors of climatology science and has an important role in management and environmental planning. in general, the behavior of climatic elements are observed in 3 form: trend, oscillation and fluctuation. these behaviors will help us to identify more the climate change...

Climate variability and change is threatening water resources around the world. One hundred and fourtheen (114) stations from Reference Hydrometric Basin Network (RHBN) around Canada with at least 30 years continuous data (up to 2011) were selected to study the trend in mean annual runoff for different periods of 30 to 100 years in step 10 years by non-parametric Mann-Kendall test. Effect of sh...

Drought is one of the natural phenomena which occurs in all climates in different parts of the world. Iran is located in the dry belt of the world. The increase of desertification, drought reoccurrence, and destruction by human in this geographical region needs more studies on spatial and temporal trend of rainfall. In this study, trends of climatic drought during 1975-76/ 2004-05 in seasonal a...

rainfall and flow rate are of the most important climatic and hydrologic parameters whose investigation and determination of their behavior are of great importance in water resources management. one of the most suitable methods available for assessment of hydro-climatological conditions in the watershed is trend analysis which is used to examine the changes of a variable during time. current st...

Groundwater is a critical resource for the development of any region. In Bhopal, groundwater also used various purposes, including domestic use and irrigation. Overexploitation due to increasing demand coupled with pollution raises concern about sustainability supplies in future. This study aimed analyze trends parameters Bhopal over 22 years using Mann-Kendall (MK) Modified (MMK) trend tests M...
