Isotope hydrology and baseflow geochemistry in natural and human-altered watersheds in the Inland Pacific Northwest, USA
(2015-02-18)
This study presents a stable isotope hydrology and geochemical analysis in the inland Pacific Northwest (PNW) of the USA. Isotope ratios were used to estimate mean transit times (MTTs) in natural and human-altered watersheds ...
Tracing water sources and fluxes in a dynamic tropical environment from observations to modeling
(Frontiers in Earth Science, 2020-11-06)
Tropical regions cover approximately 36% of the Earth’s landmass. These regions are home to 40% of the world’s population, which is projected to increase to over 50% by 2030 under a remarkable climate variability scenario ...
Hydrogeochemical baseline in a human altered landscape of the Central Pacific coast of Costa Rica
(Springer Nature, 2020)
Abstract Groundwater pollution in tropical and human-altered coastal landscapes is receiving novel
attention due to decreasing in annual recharge as a consequence of recurrent droughts and overexploitation, whereby saline ...
Groundwater and surface water connectivity within the recharge area of Guarani aquifer system during El Niño 2014–2016
(Wiley & Sons, 2018)
Recharge areas of the Guarani Aquifer System (GAS) are particularly sensitive and vulnerable
to climate variability; therefore, the understanding of infiltration mechanisms for aquifer recharge and surface run‐off generation ...
Insight into the stable isotopic composition of glacial lakes in a tropical alpine ecosystem: Chirripó, Costa Rica
(Wiley & Sons, 2018)
Tropical high‐elevation lakes are considered sentinels of global climate change. This work characterizes the hydrological conditions of tropical alpine glacial lakes located in the highlands of Chirripó, Costa Rica, using ...
Preface to Stable isotopes in hydrological studies in the tropics: ecohydrological perspectives in a changing climate
(Wiley & Sons, 2019)
Tropical regions (comprised between the Tropics of Cancer and Capricorn, 23.5°N to 23.5°S) cover approximately 36% of the Earth's landmass. They are home to 40% of the world's population, which is
projected to increase ...
Estudio de la calidad del agua superficial y su relación con las características socioambientales en la parte alta de la microcuenca del Río Poás
(Universidad Nacional (Costa Rica), 2020)
La dinámica poblacional de la parte alta de la microcuenca del río Poás, supone la existencia de una afectación al recurso hídrico superficial, ante los cambios de tipo social en temas de desarrollo urbano y gestión del ...
Isotope hydrology of a tropical coffee agroforestry watershed: Seasonal and event-based analyses
(Wiley & Sons, 2018)
Stable isotope variations are extremely useful for flow partitioning within the
hydrologic cycle but remain poorly understood throughout the tropics, particularly in
watersheds with rapidly infiltrating soils, such as ...
Isotopic composition in precipitation and groundwater in the northern mountainous region of the Central Valley of Costa Rica
(Taylor & Francis, 2016)
The linkage between precipitation and recharge is still poorlyunderstood in the Central America region. This study focuses onstable isotopic composition in precipitation and groundwater in the northern mountainous region ...
Hydrogeological responses in tropical mountainous springs
(Taylor and Francis Ltd., 2018)
This study presents a hydrogeochemical analysis of spring
responses (2013–2017) in the tropical mountainous region of the
Central Valley of Costa Rica. The isotopic distribution of δ18O and
δ2
H in rainfall resulted ...
