Comparison of modelling approaches to estimate trapping …

The Brown equation, used worldwide in agricultural sedimentation ponds, proved to be less efficient in predicting the trapping efficiency of the basins (r = 0.67, p = 0.1, leave-one-out RMSE = 47.2%) than a MLR model using the volume of the basin, the surface of the harvested catchment and the Von Post decomposition degree of the peat …

Impact of a Commercial Peat Moss Operation on Water …

The St-Charles Plain (Kent County, New Brunswick, Canada) commercial peat moss operation has been ongoing since 1983. To process the peat, a dry extraction method is used that requires extensive drainage of the peat bog. The water is directed toward sedimentation ponds, where it drains into a small brook, which feeds into a river …

Retention of Sediment and Nutrient Loads with Peak Runoff …

Pond maintenance alone failed to ensure optimal sedimentation pond efficiency. In 2008, SSC increased a few days after pond maintenance. The NB SSC 25 mg/L guideline was exceeded at all stations ...

Settling of peat in sedimentation ponds | Semantic …

Abstract Settling ponds are used to prevent erosion and the transport of suspended material from peat mines into downstream watercourses. In this study, …

Exploratory study of suspended sediment concentrations

Peat bog harvesting is an important industry in many countries, including Canada. To harvest peat, bogs are drained and drainage water is evacuated towards neighboring rivers, estuaries or coastal waters. High suspended sediment concentrations (SSC) were found in the drainage water at one particular site during the 2001–2002 …

Settling of peat in sedimentation ponds

Settling ponds are used to prevent erosion and the transport of suspended material from peat mines into downstream watercourses. In this study, …

Managing runoff, water quality and erosion in peatland

Conventional methods for controlling water quality from drainage areas include sedimentation ponds, wetlands, etc. Sedimentation ponds typically maintain a permanent pool of water to improve water quality by settling of SS and sediment-bound pollutants. ... At peat mining sites, dissolved phosphate usually constitutes 30–50% of …

Sedimentation rates in a Long Island marsh determined …

suggesting that Flax Pond was a tidal marsh during the 1870s the time of transition. The profile of 210Pb activity from site 2 gives an estimated mean sedimentation rate of 0.63 cm yr-l over the top 55 cm of marsh peat, equivalent to a deposition rate of 436

Comparison of Soil Nutrient Supply Patterns among Full and …

Peat soil nutrient availability and mineralization have been found to increase with atmospheric or soil warming (Bridgham et al. 1998; Sihi et al. 2016; Munir et al. 2017). Pond and soil warming (and subsequent nutrient availabilities) may increase following an initial deepening of water in a beaver pond (Munir and Westbrook 2021b).

Design, installation and monitoring of siltation ponds, peat …

Three sedimentation ponds were constructed to control the quality of runoff from Bog 567, a peat extraction site located 10 km northeast of Lameque, New Brunswick. Monitoring, conducted over a period of twelve months, consisted of measuring the rate of stream flow, the level of suspended sediments, the rate of peat accumulation in the …

Occurrence and trophic transport of organic compounds in sedimentation …

Sedimentation ponds are therefore recognised as a robust and cheap way of protecting nearby water bodies. Hence, thousands of sedimentation ponds have been built along Norwegian and European major roads (Meland, 2016). In Norway some sedimentation ponds receive tunnel wash water, and this is the case for one of the …

Effectiveness of surface mine sedimentation ponds

An in-field evaluation of the effectiveness of sediment ponds in reducing suspended solids in the runoff from surface mining activities was performed. Nine selected sedimentation ponds in the three eastern coal-mining States of Pennsylvania, West ia, and Kentucky were sampled under two different operating conditions--a baseline and a ...

Ditch network maintenance in peat-dominated …

Sedimentation or silt traps are small pits (1–2 m 3) in the bottom of drainage ditches constructed for capturing the eroded solids (Haahti et al. 2017). …

Ditch network maintenance in peat-dominated boreal …

Peat decomposition increases and its hydraulic conductivity decreases with years since drainage, therefore these results indicate that managing site drainage conditions in old peatland drainage areas with deep ditches has marginal effect on drainage condition. ... Sedimentation ponds are significantly larger water protection structures …
