Understanding the role of natural and anthropogenic forcings in structuring the periphytic algal assemblages in a regulated river ecosystem [PDF]

open access: yesScientific Reports, 2023
Periphytic algal assemblages in the River Sindh of Kashmir Himalaya were studied in relation to environmental factors and anthropogenic alterations like flow regulation for Run-of-River hydropower plants to understand their ecology in a regulated river ...

Predicting Cyanobacterial Blooms Using Hyperspectral Images in a Regulated River [PDF]

open access: yesSensors, 2021
Process-based modeling for predicting harmful cyanobacteria is affected by a variety of factors, including the initial conditions, boundary conditions (tributary inflows and atmosphere), and mechanisms related to cyanobacteria growth and death. While the

Evaluation of non-indigenous biological assessment tools using benthic macroinvertebrates in a regulated river in the semi-arid region of Iran [PDF]

open access: yesScientific Reports
Benthic macroinvertebrates are widely used as key indicators in the biomonitoring of aquatic ecosystems, particularly in fragile ecosystems downstream of dams.

Metabolism Regimes in Regulated Rivers of the Illinois River Basin, USA

open access: yesScientific Data
Metabolism estimates organic carbon accumulation by primary productivity and removal by respiration. In rivers it is relevant to assessing trophic status and threats to river health such as hypoxia as well as greenhouse gas fluxes.

Spatial heterogeneity and distribution patterns of dissolved carbons and total ammonia nitrogen in the upper Changjiang River under 2022 summer extreme drought conditions [PDF]

open access: yesCarbon Balance and Management
The biogeochemical cycling of carbon in aquatic systems is profoundly regulated by extreme hydrological events, particularly through their impacts on dissolved carbon species (DCs) and total ammonia nitrogen (TAN).

Scaling properties reveal regulation of river flows in the Amazon through a forest reservoir [PDF]

open access: yesHydrology and Earth System Sciences, 2018
Many natural and social phenomena depend on river flow regimes that are being altered by global change. Understanding the mechanisms behind such alterations is crucial for predicting river flow regimes in a changing environment.

Time series modeling and forecasting of a highly regulated riverine system: implications for fisheries management

open access: yesCalifornia Fish and Wildlife Journal, 2020
Here we apply seasonal time series modeling to flow and fisheries management in a highly regulated river system. Time series modeling is commonly employed to forecast future values of streamflow and extrinsic climate-related seasonal data based on ...

Natural and Geomorphological Response of the Small Lowland River Valley for Anthropogenic Transformation

open access: yesResources, 2021
The regulation of small rivers and the consequent maintenance works are common in the Central European Lowlands. This article attempts to determine the relationship between the invertebrate fauna (and consequently the biocenosis) of the small lowland ...

Ecohydrology of wetland plant communities along an estuarine to tidal river gradient

open access: yesEcosphere, 2020
Abiotic filters that interact with wetland plant communities along tidal–fluvial gradients are highly dynamic, and understanding their quantitative thresholds and relationships to interspecific competition is important during an era of sea‐level rise and

Thermal regime of a highly regulated Italian river (Ticino River) and implications for aquatic communities

open access: yesJournal of Limnology, 2016
Thermal alteration is one of the adverse effects of flow regulation sharpened in recent years due to climate changes. In this work, we characterize the thermal regime of a highly regulated river located in Northern Italy, which is the emissary of Lake ...
