Floods are both complex and destructive, in most parts of the world cause injury, death, loss agricultural land, social disruption. Flood susceptibility (FS) maps used by land-use managers land owners to identify areas that at risk from flooding plan accordingly. This study uses machine learning ensembles produce objective reliable FS for Haraz watershed northern Iran. Specifically, we test abi...

Water-yield assessment is crucial to effectively achieve water supply management at the basin scale. It affected by climate change, and Land Use/Land Cover Change (LULCC). This paper quantifies combined impact of LULCC change on yield over short long-term periods in Haraz basin, Iran. has experienced severe forest degradation, agricultural expansion, urbanization. Most lands are within plains c...

in this study species richness of earthworms in the central elburz mountains is reported for the first time based on samples collected from 33 localities along the haraz and chalus rivers. twelve species were identified representing seven genera from family lumbricidae (rafinesque-schmaltz 1815): aporrectodea caliginosa (savigny 1826), a. rosea (savigny 1826), a. jassyensis (michaelsen 1891), d...

Iran is one of the flood-prone areas in world with inappropriate climatic patterns. In this study, flood risk maps three scenarios by combining Analytic Hierarchy Process (AHP), Analytical Network (ANP) and Fuzzy (FAHP) models Ordered Weighted Average (OWA), Linear Combination (WLC) models., Local (LWLC) two new models, Multi-Criteria Analysis (WMCA) Geo Technique for Order Preference Similarit...

Climate changes pose great threats to the main services of ecosystems such as food security, water security and health. This research was carried out in Haraz river basin rangelands, Mazandaran province in the north of Iran in 2015-2017 to analyze the perspectives of Haraz river basin (HRB) pastoralists about climate change. From 5236 local pastoralists, the sample size was consisted of 350 one...

Monthly samples of six fish farms from January 2010 to December 2010 in the northern Iran, Haraz River, were used to determine relationship between chemical parameters of main water, inlet and outlet and their effects on fish growth and production. Results revealed that concentration of nutrients in outlet was more than that of inlet of farms and statistical analysis showed that there were sig...
