Sagmata stream experimental watershed: monitoring flashfloods in ephemeral streams of semiarid Patagonia (Chubut province, Argentina)

Half of the population of the Chubut Province (Argentina) lives in the Lower Valley of the Chubut River (VIRCh). The occasional rains produce flash floods in the ephemeral streams and high turbidity pulses in the Chubut River, which may cut off the provision of fresh water to the communities and flo...

description Half of the population of the Chubut Province (Argentina) lives in the Lower Valley of the Chubut River (VIRCh). The occasional rains produce flash floods in the ephemeral streams and high turbidity pulses in the Chubut River, which may cut off the provision of fresh water to the communities and flood risk as well. In order to get field data on soil erosion and hydrological processes, the Sagmata Stream Experimental Basin (CEAS), a 129 km2 pilot basin, was instrumented in 2017. Results are presented for the period December-2017 to February-2022. The mean annual rainfall was 161 mm. Seasonal variations in precipitation and duration of storms are not significant. Three events with high 10 min- rainfall intensity were recorded: 42, 45, and 63 mm/h. During the period, 17 flood events have been registered, with a maximum flow discharged into the Chubut River of 34.6 m3/s. The average sediment concentration of the flow is 33.4 g/l with a maximum registered value of 60.6 g/l. The results constitute a contribution to the knowledge of regional hydrology as well as for the formulation of projects to guarantee water security in VIRCh.

El Valle inferior del Río Chubut (VIRCh) es el lugar de asiento de la mitad de la población de la Provincia del Chubut (Argentina). Las lluvias ocasionales producen crecidas repentinas en los arroyos efímeros y pulsos de alta turbiedad en el Río Chubut que provocan el corte del suministro de agua potable a las poblaciones y riesgo de inundación. Con el objetivo de contar con información de campo de los procesos hidrológicos y de erosión de suelos, en el año 2017 se inició la instrumentación de una cuenca piloto de 129 km2 de extensión, denominada Cuenca Experimental Arroyo Sagmata (CEAS). Se presentan resultados para el periodo diciembre-2017 a febrero-2022. La lluvia media anual fue de 161 mm. No se observan variaciones estacionales en la precipitación y duración de las tormentas. Se registraron tres eventos con elevada intensidad en 10 min: 42, 45 y 63 mm/h. Durante el periodo se han registrado 17 eventos de crecidas, con un caudal máximo vertido en el Río Chubut de 34.6 m3/s. La concentración media de sedimentos transportados en suspensión por el flujo es de 33.4 g/l con un valor máximo registrado de 60.6 g/l. Los resultados presentados constituyen un aporte tanto al conocimiento de la hidrología regional como así también para la formulación de proyectos que garanticen la seguridad hídrica en el VIRCh.
