Abstract

Intense rainfall produces flooding in the Quequén Salado river basin (Buenos Aires, Argentina). To analyze the causes, a hydrogeomorphologic study was performed in the Pillahuincó Grande and Pillahuincó Chico creeks upper basin, located in the Quequén Salado river basin. The main characteristics, dynamics and processes that influence the different courses of the hydrographic basin are described. The drainage is dendritic produced by its geological structure. The sinclinals and anticlinals on the SW side have a high slope, whereas on the east side, are expressed as smooth slopes. The typical infiltration of the area is between 12 and 25 mm/h. In shallow sectors of the main streams, flow coming from the upper basin that result in floods downstream because creeks can not contain water volumes
