      Because increasing climatic variability and anthropic pressures have affected the sediment dynamics of large tropical rivers, long-term sediment concentration series have become crucial for understanding the related ...

    • The integration of field measurements and satellite observations to determine river solid loads in poorly monitored basins 

      Espinoza-Villar, R.; Martinez, J.-M.; Guyot, J.L.; Fraizy, Pascal; Armijos, E.; Crave, A.; Bazan, H.; Vauchel, P.; Lavado-Casimiro, W.

      The use of satellite imagery to assess river sediment discharge is discussed in the context of poorly monitored basins. For more than three decades, the Peruvian hydrological service SENAMHI has been maintaining several ...

    • Sediment budget in the Ucayali River basin, an Andean tributary of the Amazon River 

      Santini, W.; Martinez, J.-M.; Espinoza-Villar, R.; Cochonneau, G.; Vauchel, P.; Moquet, J.S.; Baby, P.; Espinoza, J.C.; Lavado-Casimiro, W.; Carranza, Jorge; Guyot, J.L.
