[Online] international conference
River morphology and flood control Piura River
Morfología fluvial y control de inundaciones río Piura - PERU

19 and 20 November 2020

 Objective

Research, study and particular fast track plan of rapid action “design as you go”.

150 years of human intervention have transformed the Piura River, Peru‘s main irrigation area, into a semi-channelled and regulated river with levee embankments, groynes and sedimented floodplains in the lower river basin, Bajo Piura, and a non-river-channelled reach of a sediment ejection source area in the upper basin: Alto Piura. The deviation of the natural course of the Piura river in the lower river basin, which in the past discharged into the sea, a proper river mouth, to a new point of discharge, a non-proper river mouth, with a longer river length in the last century, has resulted in a complex problem in the river morphology of the lower river basin. As a consequence, an aggradation (sedimentation) process is occurring in the lower river basin. Simultaneously, the degradation of the upper river basin, which is the source of sediment ejection into the lower basin, has continued unchecked, leading to the necessity that mitigation measures be implemented to counteract the streambed and river bank level changes, if adequate measures are not taken to solve the problem. An effective evaluation of the riverbed in this degradation-aggradation process in the upper, intermediate and lower river basins requires an understanding of the morphological processes involved in river channel geometry adjustment and projected equilibrium conditions.

The objective of this research, which will be the main topic of this conference, was to study how the aggradation-degradation process of the Piura River streambed and banks might be managed by means of an adequate river training and flood control system:

The objective of this conference is to alert local authorities to the urgency of addressing the issue of flood control in Piura, through adequate "engineering principles, organization, administration and ethics" and non-political and non-corrupt implementation, four years after the destructive El Niño 2017 flood event, caused by the lack of an integral plan and adequate decision making.

The main focus of the conference will be the following key themes:

The conference will also include presentations on fluvial morphology, flood control and how highly qualified river engineering authorities can manage rivers efficiently without political influence while maintaining engineering and ethical principles. Invited sessions from river engineering and flood control experts will be presented within the framework of river morphology and flood control of the Piura River.

The conference introduces to a fast track action plan, design as you go, with strategies for flood control, alternatives and recommendations.

An adequate flood control system based on several variables, besides of social and environmental issues will take in fact several years, and in the meantime a flood defence in the lower basin is also a must, up to the effective flood control system is ready.
