The assessment of climate change impacts on water resources and flood risk is typically underpinned by hydrological models calibrated and selected based on observed streamflow records. Yet, changes in climate are rarely accounted for when selecting hydrological models, which compromises their ability to robustly represent future changes in catchment hydrology. In this paper, we test a simple framework for selecting an ensemble of calibrated hydrological model structures in catchments where contrasting climatic conditions have been observed. We start by considering 78 model structures produced with the FUSE modular modelling framework and rely on a Pareto scheme to select model structures maximizing model efficiency in both wet and dry periods. The application of this approach in three case study basins in Peru enables the identification of structures with good robustness, but also good p...

Hydrometeorological data from the Rontoccocha Ecohydrological Monitoring System and the Soil and Water Assessment Tool hydrological model were used. The results show that climate change has a more significant impact on water resources (up to 26% increase in mean annual runoff) than land use change (up to 1%). However, when combining both factors, the effects depend on the magnitude and dynamics with which each scenario influences hydrological processes. We find that MERESE has a high potential under changing conditions, since, through afforestation practices, it can increase groundwater (GWQ; 10–20%) and reduce surface runoff (SURQ; 10–60%). However, these effects could be improved considering the findings of this study. This research evaluated the impacts of land use and climate change on the hydrological responses of a high Andean watershed, as well as the relevance of the MERESE p...

In the last two decades, approximately 2.15 million inhabitants in Peru were affected by floods, mainly concentrated in the Andean–Amazon basin, whose frequency has increased as a consequence of climate change. The objective of this research is to evaluate the potential impact of climate change on the magnitude of frequent (2-year) flood flows and the extent of flooded areas in the Huallaga River basin (HRB). We used the hydrological and hydrodynamic model MGB and an approach to select four CMIP6 global climate models (GCMs) representative of extreme conditions (Cold-dry, Cold-wet, Warm-dry, and Warm-wet) for the scenarios SSP2-4.5 and SSP5-8.5, analyzed in two future periods (2035–2065 and 2069–2099). The results show that the impacts on flood flows and flooded areas vary according to the selected GCM, with the largest increases concentrated in the headwater areas and along the ma...

La presente investigación tuvo como objetivo principal determinar la relación entre la gestión de cuentas por cobrar y la morosidad de la Caja Piura del distrito de Rioja, año 2018, pues fue un estudio de tipo descriptivo – correlacional, de enfoque cuantitativo y diseño no experimental, para lo cual se tomó como población y muestra a 48 trabajadores de la Caja Piura del distrito de Rioja, a quienes se aplicó como técnica la encuesta acompañado de un cuestionario como instrumento, obteniendo como resultados que, la gestión de cuentas por cobrar se viene desarrollando de forma deficiente (63%), ello debido a que existe una serie de falencias en cuanto a las políticas de crédito, las cuales no se basan en los estándares y normas aplicadas al crédito, asimismo se evidenció fallas en las cuentas incobrables, por otro lado el nivel de morosidad es alto (60%), debido a las de...
