“…Table 3 shows the impact of climate change on the watershed processes and type of pollution impacting the water quality. Watershed processes like soil erosion and soil washout, due to runoffs, contribute to the deposition of soil particles into water bodies leading to alteration of water quality parameter like TSS, TDS, nutrient loadings pathogen contaminant concentrations [26,27]. Presence of decayed living organisms in watershed, overheating, land degradation and excessive agricultural practices also contribute to effective flash flood, excessive evaporations, river sedimentations and depositions of more nitrogen and phosphorous resulting in the increase in organic matter fluxes, heavy metals, eutrophication processes in water bodies and decrease in DO.…”

The impacts of climate change on water quality of water bodies are associated with the climatic extreme events (heavy rainfall and flood, heat, drought, wildfires, cyclones, hurricane, super storms) as the major drivers that require knowledge of understanding. Most research studies present the role of climate change in threatening water quality, risks on drinking water and contributions of catchment in water pollution, but less attention has directed to specific sensitive water quality parameters, appropriate methodologies, risks on ecosystem and managerial practice to reduce the impacts. This review highlight the of effect climate change on surface water bodies based on recent literatures on the impacts of climate change on water quality and promote practical opportunity for better management of these impacts. We conclude that consideration of climate change preparedness plan in catchments is the best option to adopt for minimization of climate change impacts on water quality of water bodies.

“…Other projected changes to dissolved oxygen (O2) levels have been documented in nearshore environments including the North Sea (Meire et al, 2013;Wakelin et al, 2020), Arabian Sea (Lachkar et al, 2019), California Current System (Dussin et al, 2019;Siedlecki et al, 2021;Pozo Buil et al, 2021), and coastal waters surrounding China (Hong et al, 2020;Yau et al, 2020;Zhang et al, 2021;. Hypoxia projections in relatively smaller estuaries have also been documented in the Elbe (Hein et al, 2018), Garonne (Lajaunie-Salla et al, 2018), and Long Island Sound (Whitney and Vlahos, 2021).…”

Abstract. Multiple climate-driven stressors, including warming and increased nutrient delivery, are exacerbating hypoxia in coastal marine environments. Within coastal watersheds, environmental managers are particularly interested in climate impacts on terrestrial processes, which may undermine the efficacy of management actions designed to reduce eutrophication and consequent low-oxygen conditions in receiving coastal waters. However, substantial uncertainty accompanies the application of Earth System Model (ESM) projections to a regional modeling framework when quantifying future changes to estuarine hypoxia due to climate change. In this study, two downscaling methods are applied to multiple ESMs and used to force two independent watershed models for Chesapeake Bay, a large coastal-plain estuary of the eastern United States. The projected watershed changes are then used to force a coupled 3-D hydrodynamic-biogeochemical estuarine model to project climate impacts on hypoxia, with particular emphasis on projection uncertainties. Results indicate that all three factors (ESM, downscaling method, and watershed model) are found to contribute significantly to the uncertainty associated with future hypoxia, with the choice of ESM being the largest contributor. Overall, in the absence of management actions, there is a high likelihood that climate change impacts on the watershed will expand low-oxygen conditions by 2050, relative to a 1990s baseline period; however, the projected increase in hypoxia is quite small (4 %) because only climate-induced changes in watershed inputs are considered and not those on the estuary itself. Results also demonstrate that the attainment of established nutrient reduction targets will reduce annual hypoxia by about 50 % compared to the 1990s. Given these estimates, it is virtually certain that fully implemented management actions reducing excess nutrient loadings will outweigh hypoxia increases driven by climate-induced changes in terrestrial runoff.
