The study of the variation of solute concentration in different discharge scenarios (low-flow during dry season vs high-flow during wet seasons) will provide insights on the hydrological behavior of the catchment (chemostatic vs chemodynamic) and to quantify chemical weathering rates. Moreover, this proposal will identify solute sources and water pathways to assess their contribution to streamflow in the Maipo watershed. Finally, results from this proposal will allow us to investigate the processes involved in the region\u0092s Critical Zone, which extends from the canopy top to the water table, and their response to climate change, especially during drought events.\r\nSolute generation from chemical weathering reactions, and their release and transport in rivers is of vital importance in the study of water resources. Understanding solute dynamics can provide insights on global chemical weathering rates, besides forecasting hydrogeochemical composition and thus, water quality under different hydrological scenarios. This is a key point in the context of climate change in Mediterranean catchments, where drought events are on the rise. Therefore, identifying water sources in streamflow and how they respond in different hydrological conditions can contribute to understanding the dynamics of water storages and fluxes through the Critical Zone. This information can be used directly for water management and governance.\r\nGiven the importance of understanding water through the Critical Zone in Mediterranean mountainous watersheds, several questions arise:\r\n\u0096What are the dominant water sources feeding streamflow in a mountainous Mediterranean catchment?\r\n\u0096What are the main sources and fluxes of solutes and what are the chemical weathering rates in Mediterranean rivers?\r\n\u0096What are the concentration-discharge patterns in Mediterranean Chilean Rivers?\r\nTo address these questions, I propose to analyze the concentration-discharge patterns of major ions in the Maipo basin, in the Regi\u00f3n Metropolitana, along with the study of other environmental tracers such as water stable isotopes. To do so, I will conduct monthly field sampling campaigns, to measure instantaneous discharge and collect water samples geochemical analyses of major ions and water stable isotopes. The Maipo basin is properly instrumented, giving the opportunity to develop models with long-term discharge data, and integrate hydrological and geochemical results. The results will be used to calculate concentration-discharge patterns. Additionally, the data obtained from the geochemical analysis will allow the calculation of chemical weathering rates. Finally, I will develop hydrograph separation models using historical discharge data and the newly generated water stable isotopes and major ions datasets, to investigate the effects of drought events in solute sources and water pathways.\r\nThese results will provide new insights on solute dynamics, water sources and hydrological response of the Critical Zone experiencing progressive drought in mountain Mediterranean catchments, and also to provide a geochemical baseline on hydrochemistry and weathering rates for watersheds in Central Chile.\n                                        <\/div>\n                                    <\/div>\n                                <\/div>\n                            <\/div><div class=\"mt-3\"><i class=\"fas fa-solid fa-user-tag fa-fw me-2\"><\/i><small class=\"text-muted\">Investigador\/a Responsable<\/small><\/div><span class=\"caption-field-publish\"><\/span><\/div><\/div><\/div><\/div><\/div><div class=\"  circle--pattern-bottom-large col-sm-12 col-md-12 img-article\"><div class=\"holder-publish col-md-12\" style=\"border-bottom: 1px solid #35DB54\"><div class=\"content-holder h-100 component-border overflow-hidden row m-0 p-4 aling-items-center\"><ul class=\"p-0 list-style-none\"><li class=\"p-0 ms-1 me-2\"><i class=\"fa fa-solid fa-id-card-clip fa-fw\"><\/i> PIN 27\/A056<\/li><li class=\"p-0 ms-1\"><i class=\"fa fa-regular fa-calendar fa-fw ms-1\"><\/i>Enero 2022 - Diciembre 2022<\/li><\/ul><div class=\"caption col-12 p-0 col-md-12 row m-0 align-items-center\"><div class=\"px-md-1\"><small class=\"badge rounded-pill fw-semibold\" style=\"background-color:#35DB54 !important; color:#FFF\">Finalizado<\/small>\n                            <div class=\"accordion accordion-flush\" id=\"68486\">\n                                <div class=\"accordion-item\">\n                                    <h3 class=\"my-0 small-space pt-2 title-ss text-decoration-none accordion-header\">\n                                        <a role=\"button\" class=\"bg-transparent p-0\" href=\"\">\n                                            <i class=\"fas fa-solid fa-link fa-fw me-2\"><\/i>\n                                            El ion fluoruro como trazador geoqu\u00edmico e hidrol\u00f3gico en cuencas monta\u00f1osas semi\u00e1ridas: Comparaci\u00f3n con otros trazadores geoqu\u00edmicos e isot\u00f3picos\n                                        <\/a><\/h3>\n                                    <div id=\"collapse-68486\" class=\"accordion-collapse collapse\" data-bs-parent=\"#68486\">\n                                        <div class=\"accordion-body p-0 pt-4 pb-4\">\n                                            Las monta\u00f1as semi\u00e1ridas constituyen la fuente primordial de agua para las poblaciones\r\nubicadas en zonas pedemontanas.

Este ion, perjudicial para la salud de las personas, presenta concentraciones\r\nsuperiores a los niveles permitidos en las cuencas del norte de la sierra y en la cuenca del\r\nr\u00edo Huaco, en su sector central.

El objetivo de este proyecto es comprender la din\u00e1mica de la\r\nconcentraci\u00f3n y el flujo total del fluoruro a lo largo de la cuenca del r\u00edo Huaco para determinar\r\nsu sensibilidad ante los procesos hidrol\u00f3gicos en su variaci\u00f3n. A su vez, se evaluar\u00e1 su\r\npotencial como trazador hidrol\u00f3gico y geoqu\u00edmico comparativamente a otros iones como el\r\ncloruro y la composici\u00f3n de los is\u00f3topos estables de H y O del agua (2H\/1H y18O\/16O), para\r\ncomprender dichos procesos en monta\u00f1as semi\u00e1ridas. Adicionalmente, mediante el uso\r\nde estos trazadores naturales en combinaci\u00f3n con la medici\u00f3n del caudal se podr\u00e1 estimar el\r\nrendimiento h\u00eddrico de la cuenca, lo cual es fundamental para la gesti\u00f3n y manejo del recurso.\n                                        <\/div>\n                                    <\/div>\n                                <\/div>\n                            <\/div><div class=\"mt-3\"><i class=\"fas fa-solid fa-user-tag fa-fw me-2\"><\/i><small class=\"text-muted\">Investigador\/a Responsable<\/small><\/div><span class=\"caption-field-publish\"><\/span><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>[\/vc_tta_section][vc_tta_section title=&#8221;Contacto&#8221;
