This article presents results from the long term-monitoring of gully headcut retreat rates (GHRR) between 1959 and 2015 in different parts of the Udmurt Republic and is based on the use of historical aerial photographs and field observations. It was determined that GHRR decreased from 2.4 to 0.3 m yr⁻¹ during the 1959–1997 observation period and the 1998–2015 period, respectively.

Bedload transport measurements were performed with acoustic sensors (geophones and accelerometers) mounted underneath impact plates during summer 2015 in the Albula River in Switzerland. The measurements showed that the signal response in terms of geophone and accelerometer impulses is comparable for both types of sensors and that there is a good correlation between discharge data and impulses recorded by both types of sensors.

Bed sediment chemical data are not normally used in traditional water quality monitoring studies/programs. However, they can be quite useful for reconnaissance purposes to identify potential long term monitoring sites and or water quality hotspots as well as to reconstruct long term water quality chemical levels. The paper provides three examples where bed sediments have been used successfully for those purposes.

The Selenga River is the largest tributary of Baikal Lake, it's delta covers around 600 km². Suspended sediment concentrations (SSC) in the Selenga river delta were modelled based on LandSat images data. The variability in suspended sediment retention during the period 1989 to 2015 was calculated. The results suggest that SSC storage in the delta is observed during high discharges, whereas export increases under lower flow conditions. The changes in seasonal patterns are explained by wetland.

This paper describes the use of erosion model calculations and GIS spatial analytical methods for the evaluation of trends in erosion rates in the RP. Climate change, land use transformation and crop rotation modification are the main factors governing erosion rates in the region during recent decades.

The paper explores existing data bases relating to erosion and sediment transport in South Africa. It identifies a number of problems with using these and stresses the need to supplement existing data with a novel approach based on the use of sediments accumulating in small farm dams. These could provide directly comparable data by identifying a common time line in all dams using a radioactive fallout isotope called Caesium-137 that was first liberated into the global atmosphere in the 1950s.

Excess sediment has been identified as a key issue for the River Rother, West Sussex, UK, a 350 km² river catchment. The aim is to identify the severity, extent, possible causes and potential mitigation options available to reduce sediment into the river. Ten monitoring sites were installed on four major tributaries and the main channel of the River Rother to collect sediment in the river. Sediment will be compared with possible source soil samples to trace where the sediment originated.
