Climate change has important effects on earth environment and human life. Therefor, investigation and study of climate change is very essential. This study investigated rainfall, temperature, relative humidity and wind variability by analyzing data for annual and monthly climatic factors collected at 13 synoptic stations (industrial cities of Iran) by using Mann-Kendall test. The results of mon...

today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...

Climate change is nowadays a major cause of concern in water related fields because it may cause more severe, shortened or prolonged droughts or floods in the future. In this research was tried to the best model of climate change is determined from the climate change models to determining the minimum temperature, maximum temperature and precipitation for the Birjand synoptic station. For this r...

Knowledge of the spatiotemporal dynamics soil temperature in cold environment is key to understanding effects climate change on land–atmosphere feedback and ecosystem functions. Here, we quantify recent thermal status trends shallow ground using most up-to-date data set over 457 sites Russia. The consists situ temperatures at multiple depths (0.8, 1.6, 3.2 m) collected from 1975 2016. For regio...

Abstract Long-term observational data are essential for detecting and understanding local, regional and global climate change. The goal of this paper is to consider climate data of west of the Caspian Sea for any trends in Annual means of 2m temperature and precipitation at the stations of Anzali, Rasht, Astara and Lahijan for 1956-2018 period. Some inconsistencies in the data were found. Our ...

In the present study, a modelling approach based on Geographical Information Systems (GIS) analysis is presented with the aim of identifying the influence of environmental parameters on three genera, namely, Tortula, Grimmia and Bryum as representatives of Iranian bryoflora. By using ArcGIS Desktop, we produced a model for environmental variables include altitude, precipitation, temperature and...
