The purpose of this research project is to develop a hydrogeological model using FEFLOW software, aiming to obtain seepage rates in the 03 soil layers due to rainfall recharge in the Ccoyahuacho slope, and subsequently install drains. Through soil mechanics studies, results of poorly graded gravel, well-graded gravels were obtained, and with the geological study, Andesite rock was identified. Furthermore, the hydrological study yielded an intensity of 227.33 mm/h for a 15-minute duration and a 100-year return period. Additionally, a topographic survey was conducted using the Phantom 4 RTK drone, obtaining 149,354 UTM 18S topographic points. The application of the hydrogeological model resulted in a seepage rate of 0.0002 l/s without drain installation. With the subdrain installed, a seepage rate of 878.1 l/s was achieved, indicating that the flow is directed towards the drainage system. ...

Recently there are models that study the hydrological behavior in the land cover of the hydrographic basins. For this reason, it is essential to understand the hydrological impact on land cover, which will serve for the management of watersheds. The study analyzed the changes in plant cover for the periods between 1985 and 2015, where plant covers such as Tolar, Wetlands, Puna grassland, Andean grasslands, and Yaretales were identified. Therefore, it was shown that there are losses of soil covers such as wetlands at 2.39%, Puna grassland at 1.71%, and Andean grassland at 4.77%. In addition, in this research, the semi-distributed model of Soil and Water Assessment (SWAT) was applied to study the impact of land use and land cover change (LULC) on the basin's water balance under study. The model was calibrated from (1981-1992), with the flow data observed. The result indicates that the most...

This article focuses on the simulation of the hydraulic behavior of the Rimac river in a 200-meter section in the Carapongo area of Lima, Peru, in order to determine the floodable areas in the event of increases in flows that exceed historical averages, calculating the levels of water and flow speeds to characterize the effects of flooding on the inhabitants who settle in nearby areas, as happened in March 2017 in the presence of flows of greater magnitudes in the Rimac river. [1] For the development of this article, the hydraulic simulation software called Hec Ras 6.2 was used using a fixed bed model with a fixed cross section channel, for which a topographic survey, granulometric analysis and subsequent estimation of the roughness coefficient were carried out, finally the review of the hydrological information with reference to the events that occurred in March 2017 in the Coastal Niñ...

Landslides in southern Peru are primarily caused by water saturation due to precipitation. Detailed geotechnical studies have identified parameters of soil layers, such as peat bog, gravel with fine sand, colluvial deposits, weathered slate, and fractured bedrock. These elements generate seepage and compromise slope stability. This research proposes the installation of horizontal drains along the slope to capture the seepage flow, using Slide 6.0 software and finite difference modeling technique. Different scenarios, both static and seismic, were conducted to evaluate the factor of safety. The results revealed that without drain installation, the factor of safety was 1.34 in the static scenario and 0.95 in the seismic scenario. However, by implementing the drains, stability significantly improved, with a factor of safety of 1.512 in the static scenario and 1.209 in the seismic scenario. ...

Dams are very useful hydraulic structures nowadays as they allow the generation of renewable energy, such as the case of the Tablachaca dam, one of the largest in Peru, which harnesses the waters of the Mantaro River. This dam is located in the Quichuas-Huancavelica sector and provides a significant amount of energy each year. However, it also poses a significant risk to the surrounding population and the Electroperu camp since it has been observed that this type of structure can fail due to hydraulic, structural, and geotechnical factors, leading to a breach in the structure or affecting its internal functioning, potentially resulting in dam failure. In such an event, it would devastate the downstream population. In this investigation, our focus was to corroborate this hypothesis in order to identify and delimit the most affected areas by the displacement of the flow. We compiled data t...
