Using regionally downscaled and adjusted outputs of three global climate models (GCMs), meteorological drought analysis was accomplished across Ankara, the capital city Turkey. To this end, standardized precipitation index (SPI) evapotranspiration (SPEI) were projected under (representative concentration pathway) RCP4.5 RCP8.5 greenhouse gas scenarios. In general, our results show that Ankara experienced six severe two extreme events during reference period, 1971–2000. However, projections...

Most of the water quality models previously developed and used in dissolved oxygen (DO) prediction are complex. Moreover, reliable data available to develop/calibrate new DO is scarce. Therefore, there a need study develop that can handle easily measurable parameters particular site, even with short length. In recent decades, computational intelligence techniques, as effective approaches for predicting complicated significant indicator state aquatic ecosystems such DO, have created great...

Abstract The anthropogenic impacts of development and frequent droughts have limited Iran's water availability. This has major implications for agricultural sector which is responsible about 90% consumption at the national scale. study investigates if declining availability impacted agriculture in Iran. Using Mann‐Kendall Sen's slope estimator methods, we explored changes production area during 1981–2013 period. Despite decreasing this period, irrigated continuously increased. unsustainable...

Trends in river flow at national scale Iran remain largely unclear, despite good coverage of multiple monitoring stations. To address this gap, study explores the changes Iranian rivers’ discharge using regression and analysis variance methods to historically rich data measured hydrometric Our assessment is performed for 139 selected stations located data-rich basins that cover around 97% country’s rivers with more than 30 years observations. findings show most studied Iran’s (>56%)...

The state of Oklahoma located in the Southern Plains region United States. standardized precipitation evapotranspiration index (SPEI) is a widely used meteorological drought that incorporates potential (PET) into precipitation-based index. However, understanding appropriate PET method for SPEI across different temporal scales non-arid climate conditions remains limited. We compared Thornthwaite (TW), Hargreaves (HG), and Penman-Monteith (PM) equations at various accumulations, considering...

Abstract Climate change, one of the major environmental challenges facing mankind, has caused intermittent droughts in many regions resulting reduced water resources. This study investigated impact climate change on characteristics (occurrence, duration, and severity) meteorological drought across Ankara, Turkey. To this end, observed monthly rainfall series from five meteorology stations scattered Ankara Province as well dynamically downscaled outputs three global models that run under RCP...
