Rising water temperature in rivers: Ecological impacts and future resilience

Wiley Interdisciplinary Reviews Water, Journal Year: 2024, Volume and Issue: 11(4)

Published: March 5, 2024

Abstract Rising water temperatures in rivers due to climate change are already having observable impacts on river ecosystems. Warming has both direct and indirect aquatic life, further aggravates pervasive issues such as eutrophication, pollution, the spread of disease. Animals can survive higher through physiological and/or genetic acclimation, behavioral phenological change, range shifts more suitable locations. As such, those animals that adapted cool‐water regions typically found high altitudes latitudes where there fewer dispersal opportunities most at risk future extinction. However, sub‐lethal animal physiology phenology, body‐size, trophic interactions could have significant population‐level effects elsewhere. Rivers vulnerable warming because historic management left them exposed solar radiation removal riparian shade, hydrologically disconnected longitudinally, laterally, vertically.

Climate change impacts on the temperature and magnitude of groundwater discharge from shallow, unconfined aquifers

Water Resources Research, Journal Year: 2014, Volume and Issue: 50(4), P. 3253 - 3274

Published: March 27, 2014

Abstract Cold groundwater discharge to streams and rivers can provide critical thermal refuge for threatened salmonids other aquatic species during warm summer periods. Climate change may influence temperature flow rates, which in turn impact riverine ecosystems. This study evaluates the potential of climate on timing, magnitude, from small, unconfined aquifers that undergo seasonal freezing thawing. Seven downscaled scenarios 2046–2065 were utilized drive surficial water energy balance models (HELP3 ForHyM2) obtain future projections daily ground surface recharge.

Shallow groundwater thermal sensitivity to climate change and land cover disturbances: derivation of analytical expressions and implications for stream temperature modeling

Hydrology and earth system sciences, Journal Year: 2015, Volume and Issue: 19(5), P. 2469 - 2489

Published: May 26, 2015

Abstract. Climate change is expected to increase stream temperatures and the projected warming may alter spatial extent of habitat for cold-water fish other aquatic taxa. Recent studies have proposed that thermal sensitivities, derived from short-term air temperature variations, can be employed infer future due long-term climate change. However, this approach does not consider potential streambed heat fluxes gradual shallow subsurface. The groundwater particularly important regimes groundwater-dominated streams rivers. Also, recent investigated how land surface perturbations, such as wildfires or timber harvesting, influence by changing fluxes, but these typically considered disturbances also fluxes. In study, several analytical solutions one-dimensional unsteady advection–diffusion equation subsurface transport are estimate timing magnitude changes seasonal variability in temperatures. Groundwater sensitivity formulae accommodate different scenarios. suggest will warm response depends on rate warming, properties, bulk aquifer depth, velocity. results emphasize difference between (e.g., seasonal) multi-decadal) surface-temperature variability, thus demonstrate limitations using water records project warming.

Only meters below our feet, shallow aquifers serve as sustainable energy source and provide freshwater storage ecological habitats. All of these aspects are crucially impacted by the thermal regime subsurface. Due to limited accessibility however, temperature measurements scarce. Most commonly, groundwater temperatures approximated adding an offset annual mean surface air temperatures. Yet, value this is not well defined, often arbitrarily set, rarely validated. Here, we propose usage satellite-derived land instead 2 548 measurement points in 29 countries compiled, revealing characteristic trends between Here it shown that evapotranspiration snow cover impact on globally, through latent heat flow insulation.

Climate change will have both quantitative and qualitative effects on groundwater resources. These impacts differ for aquifers in solid unconsolidated rock, urban or rural locations, the principal processes of recharge.
