The peatlands of the PDNP are amongst the most degraded and contaminated in the world. Anthropogenic and climatic pressures have caused widespread erosion (Bower 1960a, 1960b, 1961; Tallis 1985; Bonn et al. 2009).Peak Pb concentrations of up to 1650 μg g −1 can typically be found between 5 and 10 cm below the peat's …

Sediment export and retention are important ecosystem processes in any landscape causing soil erosion and sediment loading in waterways consequently affecting the health of aquatic habitats downstream. The present study quantifies sediment export and retention in four watersheds, viz., Hivra, Satrapur, Konta, and Jagdalpur in the …
Soil erosion and sediment transport have significant consequences, including decreased agricultural production, water quality degradation, and modification to stream channels. Understanding these processes and their interactions with contributing factors is crucial for assessing the environmental impacts of erosion. The primary …
Chemical weathering includes carbonic acid and hydrolysis, dissolution, and oxidation. Erosion is a mechanical process, usually driven by water, wind, gravity, or ice, which transports sediment and soil from the place of weathering. Liquid water is the main agent of erosion. Gravity and mass wasting processes (see Chapter 10, Mass Wasting) move ...
Forest roads are predicted to produce up to 90% of total sediment from forest operations (Dangle et al., 2019). For example, in a small headwater watershed in Peninsular Malaysia, soil was lost from the forest road system at a rate of 272 ± 20 t ha −1 year −1, of which approximately 60% was contributed by the road's surface (Sidle et al ...
Major factors affecting sediment erosion from peat mines were assessed to provide information on the peat delivery mechanism. Surface runoff and erosion from three plots of 100 m 2 were measured in the field using three different rainfall intensities varying from 0.58–4.38 mm/min. The settling of peat was studied in the laboratory using a …
The environmental problem of peat mining involves the erosion of peat and its subsequent transport from the mining field into downstream rivers. Increased …
Sedimentation and Erosion. Sediments are material of varying size of mineral and organic origin. Erosion is the process of carrying away or displacement of sediment by the action of wind, water, gravity, or ice (Smith & Smith 1998). The process of deposition of sediment from a state of suspension or solution in a fluid is called sedimentation ...
The concept of sediment budgets can be used to link in-field erosion processes with sediment loads downstream, and express the efficiency of the catchment's sediment delivery system (Walling et al., 2002; Fig. 1). In this way, sediment reduction strategies, such as soil erosion control can be better spatially targeted.
