In Peru, the occurrence of catastrophic events causes irreparable loss of human lives and extensive material damage. These effects are increasing in scope and intensity in recent years, just as the demands increase at almost all scientific disciplines linked to land preparation tasks, demanding proposals for preventive actions or mitigation. This requirement gets extended particularly to geomorphology. In Peru, the standpoint linked to the positions aligned with the idealist, generalizing and deductivist lines of the classic Davisian geomorphology approach, is being now gradually replaced by the development of a systemic, morphoclimatic and inclusive approach. The result is that starting from direct observation of the land; this approach has contributed to the solution of concrete problems. This article discusses some experiences in the use, management and land occupation by our ancient ...

En el Perú, la ocurrencia de fenómenos catastróficos causa irreparables pérdidas humanas y enormes daños materiales. Estos efectos se vienen incrementando en magnitud e intensidad en los últimos tiempos, de igual manera, se incrementan las exigencias a casi todas las disciplinas científicas vinculadas a las tareas de acondicionamiento del territorio, demandando propuestas de acciones preventivas o de mitigación. Este requerimiento se extiende en particular a la geomorfología. En el Perú, el enfoque vinculado con las posiciones alineadas con la línea idealista, generalizadora y deductivista de la geomorfología clásica davisiana, está siendo en la actualidad gradualmente sustituido por el desarrollo de un enfoque sistémico, morfoclimático e integrador, el resultado es que partiendo de la observación directa del terreno, este último viene contribuyendo a la solución de pr...

El presente trabajo titulado GEOMORFOLOGÍA DEL ORIGEN DEL RIO AMAZONAS, aborda el no hasta hace mucho discutido tema del origen de río Amazonas, analizando para ello las formas del relieve y los procesos morfodinámicos más saltantes, de esta parte de la cordillera del Chila, a la cual se ha llegado finalmente después de numerosos acercamientos efectuadas por expediciones anteriores. La zona estudiada abarca un área aproximada de 55km2 de extensión, comprendiendo un conjunto de cuatro cuencas: Garhuasanta, Sillanque, Apacheta y Ccaccansa, las mismas que constituyen el sector del extremo inicial de esta gigantesca red hidrográfica del río Amazonas. Estas cuencas se hallan en la cordillera del Chila conocido también como cordillera Choquecorao, en la provincia de Caylloma, departamento de Arequipa. Las cuencas referidas son estudiadas en forma cualitativa y en algunos de los valor...

In the summer of 2017 the north and central coast of Peru, endured rains as they had not been registered for many years, the departments of the north and center of the country were the most affected. In Lima, 80% of the identified streams were activated, causing mudslides and floods that affected the towns of Chosica, Huachipa, Carapongo, Cajamarquilla, Santa Eulalia, Campoy, among others, all located in the Rímac river basin. The occurrence of this phenomenon has been considered atypical by its magnitude and its improvised occurrence, for which the Multisectorial Committee in charge of the study of this phenomenon (ENFEN) called it «El Niño Costero». This natural phenomenon generated disasters such as the destruction of homes, land roads, bridges, schools and other infrastructure, especially in towns located in vulnerable areas. In this context, this research aims to explain the cha...
