Lessons Learnt From Long‐Term Monitoring of River Restoration in an English Chalk Stream

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT River restoration can be difficult to evaluate due to insufficient monitoring over timescales too short to adequately capture physical and ecological response. To better understand restoration outcomes, this study quantified changes in physical habitat (depth, velocity, substrate composition) and macroinvertebrates at two restoration projects ...

Effects of spatial and environmental factors on benthic a macroinvertebrate community

open access: yesZoologia (Curitiba), 2014
Interactions between terrestrial and aquatic systems influence the structure of river habitats and, consequently, affect their benthic macroinvertebrate composition. The aim of this study was to evaluate the effects of spatial and environmental variables

Macroinvertebrate Recovery to Varying Hydropeaking Frequency: A Small Hydropower Plant Experiment

open access: yesFrontiers in Environmental Science, 2021
As the demand for hydroelectricity progresses worldwide, small hydropower operators are increasingly examining the feasibility of using existing infrastructure (e.g., settling basins) in run-of-the-river schemes for intermittent power production.

Benthic Macroinvertebrates Assemblages in the Fish Pond

open access: yesIOP Conference Series: Earth and Environmental Science, 2022
Overall, small holder of fish farmers in Kelantan in particular does not monitor their pond water quality to maintain fish health due to tedious and expensive work. Hence, this study was proposed to identify the assemblages of benthic macroinvertebrates at the fish pond for potential as a tool for water quality assessment via biological indicator.

Geomorphic Effects and Habitat Impacts of Large Wood at Restoration Sites in New England

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Large wood (used interchangeably with the term “instream wood”), which refers to trees, logs and other wood within a channel, is beneficial to river ecosystems and is being used more frequently as a component of river restoration projects. We identified metrics to evaluate the effectiveness of large wood to promote ecological and geomorphic ...
