[ 1 ] - مقایسۀ آسیب‌پذیری زیرحوضه‌های آبخیز سامیان بر اساس تغییرات مؤلفه‌های اقلیمی
پژوهش حاضر با هدف ارزیابی آسیب‌پذیری اقلیمی آبخیز سامیان در استان اردبیل انجام شد. در این راستا، نخست شاخصهای مهم اقلیمی و فیزیکی در سطح 27 زیرحوضه محاسبه و سپس به تعیین آستانهها اقدام شد. نتایج نشان داد که شاخصهای فصل خشک و مرطوب بهترتیب در محدودة 05/48 (زیرحوضة 21) تا 63/86 (زیرحوضة 12) و 99/254 (زیرحوضة 16) تا 83/130 (زیرحوضة 3) میلیمتر متغیرن...
[ 2 ] - ارزیابی و تحلیل وضعیت سلامت آبخیز کوزه‌تپراقی، استان اردبیل
پژوهش حاضر با هدف ارزیابی سلامت آبخیز کوزه‌تپراقی واقع در استان اردبیل با استفاده از تحلیل 27 معیار مرتبط با ابعاد مختلف هیدرولوژیکی، انسانی و اقلیمی انجام شد. به‌همین منظور، ابتدا اطلاعات پایه منطقه‌ای شامل داده‌های هیدرولوژی، فرسایش و رسوب، اقتصادی، اجتماعی و اقلیمی از گزارش‌های پیشین جمع‌آوری و تحلیل شد. سپس متناسب با ماهیت داده‌های مورد استفاده چندین بانک اطلاعاتی در محیط نرم‌افزار‌هایFrags...
[ 3 ] - Introducing the Flood Vulnerability Index (FVI) as a flood crisis management tool
Background and objective: Floods are among the most dangerous natural disasters that causes loss of life and property every year. The destructive effects of floods are more documentedو due to climate change and increasing economic and social development. Social and infrastructural vulnerabilities have also increased due to human settlement adjacent to river floodplains. Therefore, to prevent mo...
[ 4 ] - Modeling Production and Canopy Cover Parameters to identify the Most Effective Environmental Factors in Baghrou Semi-Steppe Rangelands of Ardabil Province, Iran
The aim of the study was to determine the most important environmental factors (topography, climate, and soil) affecting changes in production and canopy cover of plant variations and to prepare prediction maps, based on the most important factor, in semi-steppe rangelands of Hir-Baghrou, Ardabil province, Iran. First, by detecting the vegetation types and different classes of environmental fac...
[ 5 ] - Indicators and components of assessing variations and changes in climate change
Background and Objective: In the present study, concepts related to climate change and climate study scales have been studied and various indicators related to climate change have been presented and then important and practical indicators in evaluating climate change components have been evaluated. Method: Monitoring the changes in extreme climatic events requires data in short-term time scales...
[ 6 ] - Modeling of monthly flow duration curve using nonlinear regression method for un-gauged watersheds of Ardabil Province
The flow duration curve (FDC) represents the frequency distribution of water flow over a period of time, which is widely used in hydrology to evaluate different ranges of river water flow applications. Therefore, it is necessary to develop a suitable estimation model and method in un-gauged watersheds. To this end, in the present study, a modeling method based on nonlinear regression, for the p...
[ 7 ] - Hot Spots Analysis of Landscape Metrics and Runoff Landscape Index in Ardabil Province
Hot spots are often associated with places where an abnormal process has occurred. Accordingly, their identification can help experts and managers to scrutinize the state of health and sustainability, from an ecological point of view. The present study was therefore conducted to analyze the spatial autocorrelation and identify hot spots of 11 landscape metrics, the new Runoff Landscape Index (R...
[ 8 ] - Spatio-Temporal Changes of Natural Vegetation Disturbance in the Ahle Iman Watershed, Ardabil Province
The present study aimed to assess the spatio-temporal changes in the natural vegetation cover of Ahl Iman watershed, Ardabil province. For this purpose, land use maps of the three years (2000, 2010, and 2020) were extracted from Landsat satellite images. Then, seven landscape metrics (patch density, edge density, patch richness, splitting index, contagion index, Euclidean nearest neighbor dista...
[ 9 ] - Monitoring of Management Practices and Hydrological Response in the Representative and Paired Watersheds of Iran-Part one
The early 20th century has been unique because of the initiation of paired watersheds (PWs) research in several world regions. So that, between 1930 and 1970, there was a significant expansion in the setting up PWs. They are currently being used for management and conservation objectives due to their special potential and appropriate research facilities. Undoubtedly, without having comparative ...
[ 10 ] - Screening watersheds of Ardabil province concerning flood vulnerability
In recent years, the world has faced many challenges. Among the natural phenomena, the flood effect has attracted a lot of attention due to its adverse effects. More than half of the destruction and damage caused by global flooding occurs in the Asian continent, which causes loss of life, damage to infrastructure, and creates conditions of panic in communities. Increasing resilience is critical...
[ 11 ] - Investigating spatial changes of soil moisture after heavy spring rains, Fars province
Soil moisture is an important variable in climatic, hydrological, and ecological systems that link atmospheric processes to the earth's surface. The rainfall systems of the water year 2017-2018 abnormally caused more than normal rainfall in Fars province and caused major changes in the surface moisture of the soil. The purpose of this research is to analyze the spatial changes of soil moisture ...
[ 12 ] - An Overview on the Monitoring of Management Practices and Hydrological Response in the Representative and Paired Watersheds of Iran- Part Two
The present review has been compiled to monitor management practices and hydrological response in 12 representatives and paired watersheds of the country including Tangeshol (Fars), Khamesan (Kurdistan), Dehgin (Hormozgan), Zidasht (Alborz), Shush (Khuzistan), Kakhk (Khorasan Razavi), Kechik (Golestan), Kasilian (Mazandaran), Gonbad (Hamedan), Goorband (Sistan & Baluchestan), Herris (East Azarb...
