Investigating rates and mechanisms of lateral erosion in a small bedrock river using erosion pins, structure-from-motion photogrammetry, and optically stimulated luminescence dating: Konza Prairie, northeast Kansas
… the fluvial processes driving lateral bedrock erosion and the timescales over which it occurs remain poorly understood. In order to advance our understanding of how bedrock rivers erode laterally over time, I investigated past and present erosion rates at Kings Creek, an incised stream in …

The Effect of Management on Erosion of Civil War Battlefield Earthworks
… Earthworks while allowing public access. Soil erosion, both natural and human-induced, is a major concern facing the preservation of the earthworks. Currently, the National Park Service is committed to preserving these earthworks for future generations by determining which maintenance …

Annual Erosion of a Small Watershed in the North Dakota Badlands; USA
<p>Understanding the process of erosion is important and necessary to guide not only land management today, but serve as a basis for future practices. The seasonal rate of sediment transport was monitored in a small drainage basin near the North Unit of Theodore Roosevelt National Park in western …

Modeling Channel Degradation at the Watershed Scale: A Comparison of GWLF, SWAT, and CONCEPTS
… research efforts have focused on controlling erosion sources in agricultural and urban land areas. New research suggests major contributions to overall sediment loads may be due to stream channel degradation. Monitoring and modeling techniques to assess the contribution of channel sediment to …

Geomorphology and rehabilitation of erosion-degraded areas using soil bioengineering in the Rio Bacanga basin, São Luís, Maranhão State
… characteristics were related to highly developed erosion processes. The approach considered the identification of environmental fragility classes, the monitoring of an experimental station and the rehabilitation of a degraded area using soil bioengineering techniques. The adopted methodological …

Prediction of sedimentation and bank erosion due to the construction of Kahang Dam
… of the sediment dynamics and riverbank erosion downstream the dam will be of great benefit to researchers and policymakers. The present research employs the use of field techniques and estimation models to improve the (i) prediction of suspended sediment concentration, (ii) monitoring …

Terrestrial Laser Scanning for Quantifying Uncertainty in Fluvial Applications
… to measure SBR. Both total station surveying and erosion pins overestimated total volumetric retreat compared to TLS by 32% and 17%, respectively. The error in SBR using traditional methods would be significant when extrapolating to reach-scale estimates of sediment load. TLS allowed for …

The physical and ecological impacts of mangrove expansion and mangrove removal: Tauranga Harbour, New Zealand
… Elevation Tables (RSETs), buried base plates, erosion pins and sediment traps. Typically surface sediments within mangrove colonies were mud-dominated, and sedimentation provided substrate accretion up to 21 mm yr-1 in the upper reaches of the study sites. Substrate accretion was also observed …

Case study to document the condition of McConnell creek and the effect of redcedar revetments
… hydrology of a site, accelerating the natural erosion rates of the stream banks and decreasing water quality. This case study was conducted to document overall creek condition at McConnell Creek in Wichita, Kansas and estimate the effect of streambank stabilization installations. The effects of …
