Abstract Flash flood is among the most catastrophic natural hazards which causes disruption in environment and societies. mainly initiated by intense rainfall, due to its rapid onset (within six hours of rainfall), taking action for effective response challenging. Building resilience flash floods require understanding socio-economic characteristics societies their vulnerability these extreme events. This study provides a comprehensive assessment investigates main hazard, i.e. frequency,...

ABSTRACT Drought is a natural hazard developing slowly and affecting large areas which may have severe consequences on society economy. Due to the effects of climate change, drought expected exacerbate in various regions future. In this study, impact change characteristics assessed, statistical methods are employed analyse significance projections. This first study utilizing 21 recently available downscaled global models generated by NASA ( NEX‐GDDP ) evaluate projections over across United...

Abstract Flash flood is a recurrent natural hazard with substantial impacts in the Southeast US (SEUS) due to frequent torrential rainfalls that occur region, which are triggered by tropical storms, thunderstorms, and hurricanes. floods costly hazards, primarily their rapid onset. Therefore, predicting property damage of flash imperative for proactive disaster management. Here, we present systematic framework considers variety features explaining different components risk (i.e. hazard,...

Drought is an extreme climate phenomenon that happens slowly and periodically threatens the environmental socio-economic sectors. Iraq one of countries in Middle East has been dealing with serious drought-related issues 21st century. Here, we investigate meteorological drought across from 1948 to 2009 at 0.25° spatial resolution. The Standardized Precipitation Evapotranspiration Index (SPEI) utilized as a multi-scalar index accounting for effects temperature variability on drought. Four main...

Ecosystem water-use efficiency (WUE) is defined as the ratio of carbon gain (i.e., gross primary productivity; GPP) to water consumption evapotranspiration; ET). WUE markedly influential on and cycles, both which are fundamental for ecosystem state, climate environment. Drought can affect WUE, subsequently disturbing composition functionality terrestrial ecosystems. In this study, impacts drought its components GPP ET) assessed across Contiguous US (CONUS) at fine spatial temporal...

Hydrological droughts have considerable negative impacts on water quantity and quality, understanding their regional characteristics is of crucial importance. This study presents a multi-stage framework to detect characterize hydrological considering both streamflow quality changes. are categorized into three stages growth, persistence, retreat, variables (i.e., temperature, dissolved oxygen concentration, turbidity) utilized further investigate drought recovery. The applied 400 gauges...

Abstract Flash floods are common natural hazards in the southeast United States (SEUS) as a consequence of frequent torrential rainfall caused by tropical storms, thunderstorms, and hurricanes. Understanding flash flood characteristics is essential for mitigating associated risks implementing proactive risk management strategies. In this study, including frequency, duration, intensity assessed addition to their property damages. The National Oceanic Atmospheric Administration (NOAA) Storm...

Urmia Lake is a large hyper-saline lake located in the northwest of Iran. It plays an important role hydrology, climate and ecology its surrounding regions. In recent years, water level has been dropped significantly. This study investigates seasonal annual variations area from 2000 to 2011 using remote sensing data. MODIS imageries Normalized Differential Vegetation Index (NDVI) were used extract surface lake. Results reveal significant decline during last past 12 years. Analysis images...

<p>Drought risk refers to the potential losses imposed by a drought event, and it is generally characterized as function of vulnerability, hazard, exposure. Here, we assess at national level across Africa considering climate change, population growth, socioeconomic vulnerabilities. Drought vulnerability quantified using rigorous multi-dimensional framework based on 28 factors from six different sectors economy, energy infrastructure, health, land use, society, water resources....
