Evaluación de requerimientos ecológicos para el dise？o de regímenes ambientales de caudales fluviales

the environmentally advanced societies are claiming progressively an authentically integral fluvial management, that implements watershed management programs based on the paradigm of the environmental flows regime (efr). this work suggests a generic methodology for the reliable efr setting, that facilitate the water use with an environmental acceptable cost. additionally, it outlines the approaches and outstanding techniques for the evaluation of instream flow requirements, which constitute the efr by means of the instream flow regime (ifr). the adaptation of these approaches to the colombian rivers will contribute to the conservation of their valuable biodiversity.
