Bedload transport assessment is important for geomorphological, engineering, and ecological studies of gravel-bed rivers. Bedload can be monitored at experimental stations that require expensive maintenance or by using ...

The current study presents an experimental procedure used to determine bedload sediment transport rates in channels with high gradients and coarse sediment. With the aim to validate the procedure for further investigations, ...

This paper shows the advances of an experimental study of the spill of copper concentrate into immobile gravel beds. The purposes of this research are to identify the dynamics of the copper concentrate as it spills in ...

For a long time, tracer techniques based on dyes, salts and more recently heat have been used to estimate shallow flow velocities. Traditionally, flow velocity estimation using tracers would consist of tracking the movement ...

The aim of the present study is to contribute an ecologically relevant assessment of the ecotoxicological effects of pesticide applications in agricultural areas in the tropics, using an integrated approach with information ...
