%X Concern has grown in Chile to protect and conserve aquatic ecosystems taking into account the high degree of habitat degradation. As a first step towards the development of conservation plans, it is necessary to classify these ecosystems in order to learn about them and understand their different types and functions. Considering that hydrological regime is the main factor in the composition of river ecosystems, an Eco-Hydrological Classification of Chilean Rivers (REC-Chile) has been developed. REC-Chile is based on the hierarchical superposition of the controlling factors of the hydrological pattern in Chile. REC-Chile is a multi-scale classification system, allowing to represent different river patterns at different spatial scales according to the selected controlling factors. The typology of the river segment is represented as a 6-digit code, in which the position of the digit represents the controlling factor and the digit value represents the factor category. This hierarchical configuration and the assignment of geography- independent classes makes REC-Chile an easy way of interpreting the hydrological classes. Given the flexibility provided by the multi-scale nature of REC-Chile, and the simplicity in the interpretation of the classes, it is expected that REC-Chile will become a very useful and suitable tool for developing conservation plans for aquatic ecosystems. En Chile existe un aumento en la preocupaci車n por proteger y conservar los ecosistemas acu芍ticos debido al elevado estado de deterioro del h芍bitat. Como un primer paso para desarrollar planes de conservaci車n, se hace necesario realizar una clasificaci車n de estos ecosistemas para conocer y entender los distintos tipos y su funcionamiento. Entendiendo que el caudal es el principal factor en la composici車n de ecosistemas fluviales, se ha desarrollado una clasificaci車n Eco-Hidrol車gica de los r赤os de Chile (REC-Chile) basada en una superposici車n jer芍rquica de factores controladores del patr車n hidrol車gico en Chile. REC-Chile es multiescalar, permitiendo seg迆n los factores controladores seleccionados representar distintos patrones fluviales a diversas escalas espaciales. La tipolog赤a del tramo de r赤o se representa como un c車digo de 6 d赤gitos, en donde la posici車n del d赤gito representa el factor controlador y el valor a la categor赤a de 谷ste. Esta configuraci車n jer芍rquica, as赤 como la asignaci車n geogr芍ficamente independiente de sus clases, dota a la REC-Chile de facilidad en la interpretaci車n hidrol車gica de las clases. Debido a la ductilidad y flexibilidad, entregada por la multiescalaridad y po
