Vulnerability, understood as the propensity to be adversely affected, has attained importance in the context of climate change by helping to understand what makes populations and territories predisposed to its impacts. Conditions of vulnerability may vary depending on the characteristics of each territory studied-social, environmental, infrastructural, public policies, among others. Thus, the p...
چکیده این تحقیق با هدف پهنهبندی آسیبپذیری آبخوان مرند با استفاده از روشهای DRASTIC، AVI و مقایسه پهنهبندی در سه روش مذکور انجام شده است. روش DRASTIC از ترکیب هفت مشخصه هیدروژئولوژیک قابل اندازهگیری و مؤثر در انتقال آلودگی به آبهای زیرزمینی تشکیل شده است. روش AVIنیز دارای دو مشخصه است. نتایج حاصل از روش DRASTIC تقریباً کاملترین شاخص برای ارزیابی میزان آسیبپذیری آبهای زیرزمینی است که مح...
Groundwater vulnerability assessment is of crucial importance for land use/cover management. Some methods have been proposed specifically for the karst hydrogeological settings. Among them, COP and PaPRIKa, as two commonly applied recent methods, were adopted for the resource vulnerability assessment of a humid temperate karst region, north of Iran. Comparison of water bacterial content and dis...
Accelerating climate change and other cumulative stressors create an urgent need to understand the influence of environmental variation and landscape features on the connectivity and vulnerability of freshwater species. Here, we introduce a novel modeling framework for aquatic systems that integrates spatially explicit, individual-based, demographic and genetic (demogenetic) assessments with en...
The assessment of vulnerability at the community level is currently strongly evolving. Also participatory methods are seen as the way forward to act successfully at the local/community level. In order to carry out effective measures for risk reduction, information has to be available about the hazards that threaten a certain area, the elements at risk (population, buildings, infrastructure, eco...
