“…Sediment deposition and suspension in rivers resulting from intense agricultural activities have been well documented in the region (Alberto et al, 2016;Sirabahenda et al, 2017). Monitoring of suspended sediment during 2013 -2017 showed that the sediment loads are high in several PEI Rivers and stakeholders involved in watershed management have to consider mitigating actions in order to attenuate erosion (Sirabahenda et al, 2017). One cost-effective strategy to guide mitigations consists of implementing robust decision-making tools.…”

“…Secondly, those models are used to develop a methodology to calculate effective riparian buffer widths to reduce sediment loads. To this end, a lumped nonparametric model, the Artificial Neuro-Fuzzy Interface System (ANFIS; Jang, 1993) based model, including a new parameter related to soil and land-use characteristics, was developed by Sirabahenda et al (2017). This model is used along with the well-known semi-deterministic model, the Soil and Water Assessment Tool (SWAT) model with the goal of simulation of impacts from different scenarios of land use and management on sediment loads using a PEI watershed.…”

In most countries, major development projects must satisfy an Environmental Impact Assessment (EIA) process that considers positive and negative aspects to determine if it meets environmental standards and appropriately mitigates or offsets negative impacts on the values being considered. The benefits of before-after-control-impact monitoring designs have been widely known for more than 30 years, but most development assessments fail to effectively link pre- and post-development monitoring in a meaningful way. Fish are a common component of EIA evaluation for both socioeconomic and scientific reasons. The Ecosystem Services (ES) concept was developed to describe the ecosystem attributes that benefit humans, and it offers the opportunity to develop a framework for EIA that is centred around the needs of and benefits from fish. Focusing an environmental monitoring framework on the critical needs of fish could serve to better align risk, development, and monitoring assessment processes. We define the ES that fish provide in the context of two common ES frameworks. To allow for linkages between environmental assessment and the ES concept, we describe critical ecosystem functions from a fish perspective to highlight potential monitoring targets that relate to fish abundance, diversity, health, and habitat. Finally, we suggest how this framing of a monitoring process can be used to better align aquatic monitoring programs across pre-development, development, and post-operational monitoring programs.

“…The Dunk River (PEI, Canada) has historically experienced fish kills linked to the use of pesticides that can bind to soil and/or be transported by erosion processes on its highly agricultural watershed during summer rainstorms [32,33]. Degradation of its water quality through high sediment loads caused by an annual mean soil loss estimated at 10 tonnes ha −1 has been reported for over a decade [1,34]. Hence, continuously monitoring suspended sediment yield, with adequate techniques to acquire representative data, is necessary to support water resources managers and farm owners in their efforts to address the water quality issues in the Dunk River.…”

The increased soil loss in an agricultural watershed raises challengers for river water quality and a reliable automated monitoring for suspended sediment concentrations (SSC) is crucial to evaluate sediment budgets variation in systems. The aims of this study were (1) to test if an acoustic doppler current profiler (ADCP) would give similar results to turbidity probe measurements as a high frequency monitoring tool for suspended sediment; and (2) to analyze the relationship between sediment drivers and SSC in a typical agricultural drainage basin. The acoustic and optical backscatter sensors were used to collect SSC data during the ice-free seasons of four consecutive years in the Dunk River (PEI, Canada). The slopes of the relationships between the two SSC indirect measurements were not significantly different than 1. Correlations between SSC and hydro-meteorological variables showed that the high SSC values were more associated with the streamflow and water velocity than precipitation. This study highlighted the great potential of ADCP for the continuous monitoring of suspended sediment in an agricultural watershed. For summer periods the prevalence of clockwise hysteresis (74.1% of measured rainstorm events with SSC > 25 mg L−1) appeared related to rainstorm behaviors.
