Floods are a natural phenomenon that in many cases impacts on population, public infrastructure and services, among others. A body of evidence suggests that extreme climatic events will intensify due to El Ni~no-Southern Oscillation phenomenon and global warming. In that context, this thesis is aimed to provide tools to articulate climatic, hydrologic and hydraulic modeling. To this end, the Rimac basin, whose waters are the main source of Lima city (30% of the whole population of Peru), was selected as study area. The present investigation has concentrated on three tasks, namely: [1] to adapt the Genie Rural a 4 parametres Journalier (GR4J) rainfall-runo model for the Rimac river basin to reproduce and forecast daily and hourly discharge in a semidistributed approach; [2] to generate a digital river bed elevation model using the structure-from-motion technique, exploring its potential as input for hydraulic models; [3] to correct general circulation model named Hadley Global Environment Model 2 (HadGEM2) of the Coupled Model Intercomparison Project (CMIP5) using Statistical Downscaling used for the precipitation. Under the light of our results, we believe that the aforementioned techniques have the potential to overcome the limitations in hydro-meteorological and morphological data for the Rimac River basin and other basins. Thus, they can be used to build an integrated system flood management for the Rimac River. The present thesis is organized as follows: the first chapter presents the general aspects of the thesis. Chapter 2 focuses on the study of the temporal downscaling of the hydrological GR4J model, Chapter 3 describes the digital reproduction of a shallow river bed using the structure-from-motion technique. Likewise, Chapter 4 focuses on the technical aspects for the correction of the general circulation model family named HadGEM2 using statistical downscaling. Finally, in Chapter 5 we present the general conclusions of this study and the future work we suggest.
