Non-destructive investigation on small earth dams using geophysical methods: Seismic surface wave multichannel analysis (masw) and s-wave refraction seismic methods
(2020-01-01)
The application of non-destructive methods of investigation in dams, such as refractive seismic analysis and multichannel surface wave analysis (MASW) are increasingly effective from the point of choosing the best dam site, ...
Effect of a dam on epilithic algal communities of a mountain stream: before-after dam construction comparison
(PAGEPress, 2013-02)
In this study we evaluated the effect of a dam on epilithic algal communities by analyzing community response after dam construction and by comparing community composition, structure and biomass upstream and downstream of ...
Dams versus habitat: predicting the effects of dams on habitat supply and juvenile rainbow trout along the Santa Cruz River, Patagonia
(Springer, 2015-02)
Because of their remote location and lack of supporting infrastructure, large glacial rivers of southern Patagonia have remained free of dams. But this is bound to change: two dams proposed for the Santa Cruz River would ...

Effects of a Dam Reservoir on the Distribution of Heavy Metals in Two Chilean Native Freshwater Fish Species
(Springer, 2016)
In order to determine the effect of a dam on metal concentrations in riverine fish species, we studied fish inhabiting the influent (Cachapoal River) and effluent (Rapel River) of the Rapel Reservoir in central Chile. Heavy ...
