Evaluation of climate change and its possible consequences on hydrological processes in catchment will help to the challenges of water resources managers and decision makers in the future. One of the common tools for evaluating of this event is utilization of rainfall-runoff model to simulate the hydrological process. The aim of this study is to investigate effects of climate change on runoff a...

increasing of energy demand and decreasing of water resources, could make the future energy production as a big challenge. climate change is one of the main reasons for water resources limitation. future precipitation and air temperature, change hydrological conditions and directly effect on the hydropower production. for showing the future condition and making it possible to manage the hydropo...

Abstract This study examines the effects of climate change on runoff in the Yellow River basin in Khuzestan province. In this study, the combination of 14 general circulation models under two emission scenarios A2 and B1 were used for simulating the climatic variables in the next period (2025-2054) compared to the baseline period (1971-2000). The weighting method of mean observed temperature...

The impacts of climate Change, more than being influenced by the change in precipitation amount, is affected by the changes imposed by this phenomenon on rainfall regime (intensity and frequency); it means that climate change can cause extensive droughts/floods due to impact on temporal and spatial rainfall distribution, and hence, conducting some studies on return period of extreme rainfalls s...

increasing greenhouse gases in recent decades and increasing its resulting temperature has causes the imbalance of the earth’s climate system and widespread climate changes in most regions of earth planet. development strategic policy in this area has been forced with a big challenge because of the need for water in the central region on the one hand and water resource constraints on the other ...

The Solanaceae family with 49 species of 10 genera is one of the important nutritional, economical, medicinal and ornamental families in which six genera of them are classified in the group of wild relatives. Predicting the effect of climate change on the distribution of plant species is important for their management and conservation. In this study, the effects of climate change on this family...
