Significance Iran is facing a state of water bankruptcy that threatens its socioeconomic development and natural environments. Using an exceptionally rich measured groundwater dataset, we illustrate the extent severity Iran’s depletion salinization problems during 2002 to 2015 period, when number extraction points nearly doubled. nonrenewable withdrawal was about 66 million m 3 in 1965, which cumulatively grew approximately 133 × 10 2019. This increase 3.4 times capacity famous Three Gorges...
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...
Cycling of water quality constituents in lakes is affected by thermal stratification and homo-thermal conditions other factors such as oligotrophication, eutrophication, microbial activities. In addition, hydrological variability can cause greater differences residence time cycling man-made (reservoirs) than natural lakes. Thus, investigations are needed on vertical mixing new impounded reservoirs, especially those constructed to supply domestic water. this study, sampling campaigns were...
Although numerical water quality models offer valuable insights into thermal stratification (TSn) and mixing dynamics in lakes, they are often resource time consuming, limiting their applications for investigating a large number of lakes over wide geographical area. An alternative approach is using well-known classification systems, which require minimum data to provide acceptable information on TSn patterns lakes. This study investigates the regimes 198 dam reservoirs located Iran, Lewis's...
This study aims at understanding the impacts of projected climate change on hydrological processes within Maumee River watershed (16 395 km 2 ) lying in Lake Erie Basin using soil and water assessment tool (SWAT). The model was calibrated validated for a baseline time‐period 1995–2005. Downscaled ensemble temperature precipitation data from three general circulation models (GCMs) then used to assess future flow, sediment, nutrient loading mid‐century (2045–2055) late‐century (2089–2099) time...
Abstract In this study, metal concentrations in the water column and surface sediment of Sabalan Dam Reservoir (SDR) were determined. Moreover, heavy pollution index (HPI), contamination (CI), evaluation (HEI), enrichment factor (EF), geo-accumulation (Igeo), quality guidelines (SQGs), consensus-based SQGs (C-BSQGs), mean probable effect concentration quotients (mPECQs) evaluated for sediments SDR. It was observed that river entry lower, but those higher than corresponding values vicinity...
Rapid industrialization and population growth have elevated the concerns over water quality. Excessive nitrates phosphates in system an adverse effect on aquatic ecosystem. In recent years, machine learning (ML) algorithms been extensively employed to estimate quality traditional methods. this study, performance of nine different ML is evaluated predict nitrate phosphorus concentration for five watersheds with land-use practices. The distribution affects model all urban watersheds, regular...
The utilization of waste materials to control phosphorus (P) pollution has been intensively studied as a promising strategy achieve sustainable wastewater treatment. Although many methods are proposed and investigated develop modified waste-based adsorbents, core yet still-debated issue is their effectiveness viability in real-world applications. Therefore, this critical review summarizes the current research state on use forms adsorbents for dissolved reactive P removal from wastewater....
The formation of hypoxic zone in the Gulf Mexico can be traced to agricultural watersheds Midwestern United States that are artificially drained order make land suitable for agriculture. A number best management practices (BMPs) have been introduced improve water quality region but their relative effectivenss these BMPs reducing nutrient load has not properly quantified. In determine useful discharge from a tile watershed, Soil and Water Assessment Tool (SWAT) model was calibrated validated...
The use of global and regional climate models has been increasing in the past few decades, order to analyze future natural resources socio-economic aspects change. However, these model outputs can be quite biased, which makes it challenging them directly for analysis purpose. Therefore, a tool named Climate Data Bias Corrector was developed correct bias climatic projections historical periods three primary variables—rainfall, temperature (maximum minimum), solar radiation. It uses quantile...
Climate change will profoundly affect hydrological processes at various temporal and spatial scales. This study is focused on assessing the alteration of water resources availability low flows frequencies driven by changing climates in different time periods 21st century. evaluates adaptability prevailing Global Circulation Models (GCMs) a particular watershed through streamflow regimes. analysis was conducted Great Miami River Watershed, Ohio analyzing historical future simulated using 10...
