Available in PDF, EPUB and Kindle. Book excerpt: La erosión del suelo es la separación del material superficial por la acción del viento ( eólica) o del agua ( hídrica) de la masa de material en la que se encuentra. Actualmente existen viviendas y núcleos urbanos bajo cuencas naturales. Esto ha ocasionado que gran cantidad de material sólido erosionado a causa de la fuerza del agua llegue a las redes de alcantar illado generando problemas de acumulación y pérdida de capacidad de desagüe, en lugar de llegar a los cauces naturales como lo hacía antes. Una de estas cuencas periurbanas es la cuenca AVIAR , que tiene menos de un kilómetro cuadrado y se encuentra en la Comú d'Encamp(Andorra). Esta cuenca es el caso de estudio del presente proyecto. El desarrollo de los modelos de erosión tiene como objetivo facilitar la estimación del material sólido erosionado y diseñar así las posibles medidas de protección para evitar la pérdida de suelo. Se distinguen dos grandes grupos de modelos de erosión, los modelos empíricos y los modelos de base física . Como modelos empíricos se ha descrito el modelo USLE ( Universal Soil Loss Equation ), que expresa el promedio de las pérdidas anuales de suelo a largo plazo . Además, se han descrito las formulaciones que surgieron a partir de ésta, la RUSLE (USLE Revisada), que aporta nuevas metodologías de cálculo; y la MUSLE (USLE Modificada), que permite obtener el volumen de sedimentos en un determinado ev ento . Se han des crito varios modelos de base física según sus caracter ísticas, si bien , el presente estudio se centra en el cálculo de sedimentos mediante KINEROS 2, modelo en base SIG semidistribuido y de dominio público utilizado para este extremo. Se ha discretizado el modelo en subcuencas de t amaño reducido y se ha comparado los resultados obtenidos con los d el modelo ya validado de Zambrano et al. 2014, aplicado previamente en la misma cuenca objeto de estudio. Se ha calculado el volumen de material sólido producido e n la cuenca AVIAR durante el año 2012 con todos los modelos empíricos descritos y se han comparado con la suma de los sedimentos estimados por KINEROS 2 a lo largo de todos los eventos del año. Los resultados obtenidos dan una idea del orden de magnitud de l material sólido erosionado anualmente, que en este caso se encuentra entre 20 y 30 toneladas por hectárea y año. Se hubieran podido ajustar más los resultados si se hubiera contado con datos medidos a la salida de la cuenca calibrando apropiadamente KINE ROS 2.

This book was released on 2019-11-26 with total page 3006 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first Pan-American Conference on Soil Mechanics and Geotechnical Engineering (PCSMGE) was held in Mexico in 1959. Every 4 years since then, PCSMGE has brought together the geotechnical engineering community from all over the world to discuss the problems, solutions and future challenges facing this engineering sector. Sixty years after the first conference, the 2019 edition returns to Mexico. This book, Geotechnical Engineering in the XXI Century: Lessons learned and future challenges, presents the proceedings of the XVI Pan-American Conference on Soil Mechanics and Geotechnical Engineering (XVI PCSMGE), held in Cancun, Mexico, from 17 – 20 November 2019. Of the 393 full papers submitted, 335 were accepted for publication after peer review. They are included here organized into 19 technical sessions, and cover a wide range of themes related to geotechnical engineering in the 21st century. Topics covered include: laboratory and in-situ testing; analytical and physical modeling in geotechnics; numerical modeling in geotechnics; unsaturated soils; soft soils; foundations and retaining structures; excavations and tunnels; offshore geotechnics; transportation in geotechnics; natural hazards; embankments and tailings dams; soils dynamics and earthquake engineering; ground improvement; sustainability and geo-environment; preservation of historic sites; forensics engineering; rock mechanics; education; and energy geotechnics. Providing a state-of-the-art overview of research into innovative and challenging applications in the field, the book will be of interest to all those working in soil mechanics and geotechnical engineering. In this proceedings, 58% of the contributions are in English, and 42% of the contributions are in Spanish or Portuguese.
