Análisis de las condiciones actuales y propuesta para la protección yo rectificación del tramo del río Catamayo sector el Boquerón, Cantón Catamayo, Provincia de Loja

Abstract

Abstract: The engineering of rivers has the purpose of determining the morphometric and hydraulic parameters of the channels or water courses; as well as establishing behavioral changes over time in its stretchesand sections. Characteristics that are altered showing scour and / or sedimentation; as a consequence of extreme extraordinary events that produce critical speeds and considerable shear stresses or due to anthropic factors resulting from human activities. In the present research work, the main morphological processes existing in the riverbed have been characterized, the section ofthe Catamayo river The Boquerón neighborhood(Loja province) hydraulically evaluated, the behavior of the riverbed through its extraordinary maximum avenue with the Hec-RASprogram analyzed, calculated its granulometry, established its general scour and examined the effects of mining on the Catamayo River. Obtaining the location of the areas susceptible to floods, overflows and undermining for a maximum annual flow with a return period of 100 years. Finally, to show a typology of structural and non-structural works that could be used in the locality.
