The cities of Moquegua and Ilo are located in a desert close to the Atacama Desert and the supply of water for population use in the current scenario and projected for a 50-year horizon is a concern, that is, to the year 2071; For this reason, the calculations of the current and projected population quantity have been made with a growth rate of 1.6% established by the National Institute of Statistics (INEI). Currently, the demand for water for population use in Moquegua is fully met with contributions from the Pasto Grande dam, but there is a water deficit for Ilo of 43 l/s. In the year 2071 the city of Moquegua will have a population of 204,340 inhabitants and the demand for water for population use will be 0.591 m3/s with an average increase of 7 l/s per year; and the city of Ilo will have a population of 178,722 inhabitants and the demand for water will increase to 0.517 m3/s with an ...

The main objective of this article is to demonstrate the importance and necessity of applying amorphous gabions around the pillars of the continental bridge, to counteract the impact of scour. For the development of the research, the local scour that occurs in the pillars of the Continental Bridge (Madre de Dios, Peru) was calculated, analyzed and compared for return periods of 100 and 500 years; The Hec Ras software was used to perform the hydraulic modeling. The development of the article was accomplished by compiling scour calculation methodologies, such as the Colorado State University (CSU) method. Additionally, it was possible to reach the conclusion that, when working with the CSU method, more real values are obtained in terms of local scour.

Debris flows are one of the processes of mass movements that are generated by heavy rains and are activated in the upper parts of the basins. The application case of the present research carried out in the Rio Seco stream in the district of San Bartolomé, located in the Province of Huarochirí, Department of Lima seeks to recreate a debris flow event that occurred on February 2, 2017 as a result of the climatic phenomenon in the Lima Andes. Likewise, it seeks to identify the areas of debris flow threats for different return periods Tr = 100 and Tr = 500 years. For this investigation, the mathematical model is applied using the FLO-2D software, which will process topographic data, rheological properties of the debris fluid and liquid hydrographs in different return periods. Finally, processing the data, results such as flow depth, maximum flow velocities of possible deposition zones, sed...
