Factors Affecting Sediment Accumulation in Sedimentation Ponds
The efficiency of sedimentation ponds to retain solid material has been monitored for a considerable period of time in peat production areas in Ireland. The efficiency of sedimentation ponds in six forestry board districts was investigated during summer 1988. The variation in the sediment accumulation of the sedimentation ponds was …

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 …

High concentrations of suspended solids in coal mine sedimentation ponds are a factor in lowering water quality. This study focuses on the influence dissolved solids have on concentration and settling of suspended solids. Water samples from sedimentation ponds in Eastern and Western Kentucky were used to evaluate water composition in such ponds.

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 ponds, and the …

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, three different sedimentation ponds were compared under laboratory conditions. The ponds were built on 1/10 and 1/20 scales. Two types of experiments were carried out.

Retention of suspended solids and sediment bound nutrients from peat
Increased requirements for drainage water treatment has lead to the development of new methods for removing suspended solids and nutrients from peat mine drainage waters. Peak runoff control, constructed floodplains and sedimentation ponds were studied in the field at the Pohjansuo peat mine in Central Finland. Sediment and nutrient …

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).
