Ephemeral rivers, geomorfphological evolution and mapping. A case study in NE Iberian Peninsula
Ibisate González de Matauco, Askoa
; ; ; ; ; (International Association of Geomorphology, 2022-09)
Ephemeral rivers (IRES – Intermittent Rivers and Ephemeral Streams) differ from perennial rivers in that they do not have a base flow, therefore, when direct flow stop, they dry up. This condition is spatially accentuated ... -
Geomorphological evolution of ephemeral rivers through historical and UAVs images
Ibisate González de Matauco, Askoa; ; ; ; ; ; ; (EGU, 2022-04-19)
Ephemeral rivers hydromorphological processes are intermittent and many times of fast response. Therefore they remain still quite unknown. The geomorphological mapping of river forms and geomorphological units is a useful ... -
Hydromorphological characterization, assessment and monitoring in ephemeral streams: a case study in NE Iberian Peninsula
; Ibisate González de Matauco, Askoa; ; ; ; ; ; ; ; ; ; (International Association of Geomorphology, 2022-06-20)
Ephemeral streams are an important reality in the Mediterranean area, constituting more than 50% of the channel network in the eastern region of the Iberian Peninsula. The northernmost cases are located in the semi-arid ... -
Sediment displacement evolution after dam removal in a mountain river (Oioki dam, Leitzaran River)
; Ibisate González de Matauco, Askoa; Sánchez Pinto, Ibán ; ; ; ; ; (EGU, 2021-04)
Bedload sediment transport was monitored from 2016 to 2020 in the Leitzaran River, in a reach affected by the removal of 7-meters high dam (Oioki dam). The removal was accomplished in two phases, the 3 first meters were ...
