Hydraulic Analysis of Control Structures for Non-Newtonian Flow Vulnerability in Tinajas Creek

Abstract:

In the world, non-Newtonian flows, also known in Peru as landslides, currently generate human and, above all, material losses, and they are activated when heavy and prolonged rains occur. The magnitude and frequency of these phenomena have increased in the last 50 years not only due to the lack of management of water resources in streams, but also now due to the effects of climate change that has generated a change in the regional and local water cycle. To analyze this vulnerability in the Tinajas stream with 13km in length, a field campaign was executed and important precipitation data collection, then with the definition of the conceptual model a numerical model was applied, the latter was validated with a water footprint that occurred in 2017, with this methodology, the location of control structures called dikes of 150 m long, 5m wide and 4m high in strategic areas in the creek was proposed, and predictive scenarios were simulated to evaluate the contribution of the containment dikes to the vulnerability of this non-Newtonian mixture that converges more frequently in the Tinajas creek. The results of the hydrologic scenarios were analyzed with and without the control structures, obtaining up to 60% containment for a 200-year hydrologic event.
