      Rovira Garcia, Albert; Ibáñez, Carles; Martín Vide, Juan Pedro (2015-11)
      Article
      Accés obert
      Several attempts to estimate the suspended load and the sediment deficit caused by the reservoirs have been carried out in the lower Ebro River. However, existing data are scarce, scattered along time and space, and obtained ...
