In the present work, a review was made of the current state of the assessment of the climate impact on the availability of surface waters in South America. A review of 72 scientific articles refereed and indexed during the period 2010 to 2019 of 10 countries was made: Argentina, Bolivia, Brazil, Colombia, Chile, Ecuador, Paraguay, Peru, Uruguay, and Venezuela. Scientific articles in Spanish, English and Portuguese were reviewed. It was obtained that the variables related to the topic were 28, of which 7 were the main ones: climate change, rain, vulnerability, climatic variability, hydrological modeling, water regulation, and rural development. It was observed that there is an increase in the number of scientific articles carried out in the last five years, reflecting the interest of South American countries in the presence of climate change and its iIn the present work, a review was made...

In the district of Ricardo Palma, human settlements are located near streams, which are seriously affected during the heavy flooding season (rainy season), which increases due to the presence of the El Niño Southern Oscillation (ENSO) and the global effect of climate change. To get to know the flood zone 09 de Octubre - La Ronda, Ricardo Palma, software was applied to obtain the area of influence to study, and to know 10.5 software was applied to obtain the area of influence to study, and to know the rainfall record of the National Water Service. Meteorology and Hydrology of Perú(SENAMHI) for a continuous period of 27 years of maximum daily rainfall, with the HEC HMS 4.9 software the maximum design flows for different return periods were obtained, and the HEC RAS 6.2 software to obtain the flooding area. To find out the support of the authorities in the presence of the Niño Southern O...

El objetivo de la presente investigación se realizó para evaluar los efectos del cambio climático en las aguas superficiales del río Santa y en la producción agrícola, centro poblado de Rinconada - en el distrito de Santa, Áncash, Perú. Se analizaron las variables cambio climático, aguas superficiales, y producción agrícola. Se trabajó con la información recabada de Senamhi (Servicio Nacional de Meteorología e Hidrología del Perú), a través de base de datos Pisco, la Junta de usuarios de Santa, la Comisión de Regantes de Rinconada y el sistema integrado de estadística agraria de la región Ancash. El cambio climático se modeló entre 2006 y 2015, a través de la temperatura, y la precipitación histórica frente a las aguas superficiales y la producción agrícola, y se seleccionaron las mejores ecuaciones de regresión. Se observa que los agricultores muestran preocu...

The effect of climate change on the surface waters of the Santa River, the town center la Rinconada, Ancash, Peru, was assessed. Climate change was modeled between 2006 - 2015, through temperature, precipitation, and historical evapotranspiration versus surface waters based on water availability, and the best regression equations were selected. A validated survey of users of the Rinconada Irrigation Commission (CRR) was also taken. The best equation was exponential type for surface water and average precipitation. In contrast, for surface water and climate change the most appropriate was multiple linear regression. In relation to the survey, 83.33% strongly agree that they are concerned about climate change, and 81.37% agree that they are fully prepared for climate change caused by high temperatures. 27.5 % strongly disagree that the amount of water available in the canals has decreased ...

Climate change has a significant impact on river flows, leading to overflows and floods that affect populations, especially in Andean regions. This study examines flood scenarios in the Cunas River Basin (Junín, Peru) through hydrological and hydraulic simulations under various climate projections. A Reliability Ensemble Averaging (REA) approach was employed using CMIP6 climate models. In this analysis, precipitation data were processed, basin parameters were calculated, and peak flows and the extent of flood-prone areas were estimated. HEC-HMS software was used to simulate peak flows corresponding to return periods of 25, 50, 100, 139, and 200 years, while HEC-RAS was employed to determine flood zones. Model calibration and validation relied on historical precipitation data from nearby stations. The results indicate a considerable increase in peak flows and flood-prone areas due to cli...

The study of sustainable construction materials is getting attention, since the materials must be ecological, recyclable and renewable to generate a positive impact on the environment as a substitute for the construction materials currently used in rural areas of Huancayo. The objective of this research is to determine a sustainable material with resistant mechanical properties, such as reinforced blocks with Agave americana L fiber. The block components were sand, clay and silt, in order to evaluate its behavior, 5 dosages of fiber were proposed: 0%, 0.25%, 0.5%, 0.75% and 1%, these were expressed with respect to the total weight of the sample, on the other hand, the fiber used was cut to obtain a length of 25mm. Strengths were evaluated using the simple compression method, the Brazilian diametral compression tensile method and the modulus of rupture method. The result for the most opti...
