Environmental Flow Requirements of Estuaries: Providing Resilience to Current and Future Climate and Direct Anthropogenic Changes

Frontiers in Environmental Science, Journal Year: 2021, Volume and Issue: 9

Published: Nov. 17, 2021

Estuaries host unique biodiversity and deliver a range of ecosystem services at the interface between catchment ocean. They are also among most degraded ecosystems on Earth. Freshwater flow regimes drive ecological processes contributing to their economic value, but have been modified extensively in many systems by upstream water use. Knowledge freshwater requirements for estuaries (environmental flows or E-flows) lags behind that rivers floodplains. Generalising estuarine E-flows is further complicated responses appear be specific each system. Here we critically review E-flow 1) identify key (hydrodynamics, salinity regulation, sediment dynamics, nutrient cycling trophic transfer, connectivity) modulated regimes, 2) drivers (rainfall, runoff, temperature, sea level rise direct anthropogenic) generate changes magnitude, quality timing flows, 3) propose mitigation strategies (e.g., modification dam operations habitat restoration) buffer against risks altered build resilience indirect anthropogenic disturbances. These support re-establishment natural characteristics which foundational healthy ecosystems.

An integrative salt marsh conceptual framework for global comparisons

Limnology and Oceanography Letters, Journal Year: 2023, Volume and Issue: 8(6), P. 830 - 849

Published: July 15, 2023

Abstract Salt marshes occur globally across climatic and coastal settings, providing key linkages between terrestrial marine ecosystems. However, salt marsh science lacks a unifying conceptual framework; consequently, historically well‐studied locations have been used as normative benchmarks. To allow for more effective comparisons the diversity of marshes, we developed an integrative framework. We review ecosystem‐relevant drivers from global to local spatial scales, integrate these multi‐scale settings into framework, provide guidance on applying framework using specific variables 11 examples. Overall, this allows appropriate comparison study sites by accounting global, coastal, inter‐, intra‐system unique each marsh. anticipate that incorporating will mechanism critically evaluate research questions foundation quantitative studies deepen our understanding function scales.

Drivers of rising monthly water temperature in river estuaries

Limnology and Oceanography, Journal Year: 2024, Volume and Issue: 69(3), P. 589 - 603

Published: Jan. 12, 2024

Abstract River estuaries are habitats for a variety of organisms, including many temperature‐sensitive species; water temperatures in affected by several factors as they influenced both terrestrial and marine environments. Therefore, understanding the that influence river essential environmental management. However, no information exists on temperature change at high temporal resolution over wide area; moreover, relationship with has not yet been clarified. Here, we have described actual status riverine its area Japanese archipelago. Our results indicated 217 294 rivers showed significant monthly increase temperature. The average annual rates was highest October 0.090°C yr −1 lowest February 0.068°C . Furthermore, snowfall, air increase, sea temperature, land use were identified increasing rate increase. Factors influencing estuarine varied from month to month—with meteorological being strongest influencers spring fall, anthropogenic winter. findings emphasize importance considering only oceanographic phenomena, but also influences topographic features understand pattern changes estuaries.
