5 Mountain environments are sensitive to disturbance both from climate change and anthropogenic impacts (Ives & Messerli 1989). 6 The incidence of geomorphological hazards tends to be high in mountainous, high-energy environments where narrow valley floors are juxtaposed with steep unstable side slopes. Infrastructure and population are always at risk and this risk increases as expansion of roads and settlements continue. These issues are often greatest in mountainous terrain where population and infrastructure have developed along upland river valleys.
In simple terms this depicts the mountain sediment system as a series of sediment stores linked by a series of transfer processes (Fig. 4). Recognizing and quantifying significant sediment stores and the processes that link them is the basis of the sediment budget approach. The seminal work by Rapp (1960) working in the Kärkevagge catchment in Sweden used this methodological approach and inspired others to follow a similar approach in identifying the significance of sediment storage in regulating the sediment yield Morphoclimatic models Process dynamics and activity from mountain catchments (Church & Ryder 1972).
Pesticides, PCBs, some radionuclides) the baseline value is zero, and contamination assessment is relatively straightforward. g. metals, phosphorus). In rare cases this can be accomplished through analysis of monitoring data or archived samples, but in most cases values are determined through the analysis of sediments that have accumulated through time (Smol 2002). Threshold-effect values are often determined through an assessment of the physical, chemical or biological nature of the sediment, or a combination of these.
