In the arid and semi-arid area's rainfall have considerable changes in terms of time and amount that make the water resource management an important issue. In this research, using both Boolean and Fuzzy logic were zoned potentiality suitable areas for construction of underground dams. The study area is located in the central region of Ardabil province with 7461 km2 area and semi-arid climate. F...

This study was conducted to identify suitable sites for planting Avicennia marina in Soltani Khore of the urban coast of Bushehr. The most effective criteria for Avicennia marina planting include land characteristics (i.e. land use, slope, elevation, soil electrical conductivity, soil texture, and soil type), seawater (i.e. tidal range, wave, acidity, electrical conductivity, and salinity), and...

Managed relocation (MR) has rapidly emerged as a potential intervention strategy in the toolbox of biodiversity management under climate change. Previous authors have suggested that MR (also referred to as assisted colonization, assisted migration, or assisted translocation) could be a last-alternative option after interrogating a linear decision tree. We argue that numerous interacting and val...

Rainfall-Runoff simulation is one of the main subject of hydrology and environmental management. Therefore, researchers are constantly interested in finding new ways to solve this problem and modify existing models or modeling methods. However, the lack of statistics and information from the poor development of hydrological networks has always been a major problem in countries that facing finan...

A case study of the Sacramento Basin is undertaken to examine problems of planning for the impacts of climate change on water resources utilizing output from general circulation climate models. This work provides a sensitivity analysis linking climate, stream ̄ow, and planning decisions. Water resource planners want reliable time series of stream ̄ow in the basin. Sacramento basin hydrological mo...
