Groundwater recharge mechanisms inferred from isoscapes in a complex tropical mountainous region
(AGU Publications, 2016-05-23)
Stable isotope variations and groundwater recharge mechanisms remain poorly understood across the tropics, particularly in Central America. Here stable isotopes (δ18O and δ2H) in groundwater, surface water, and rainfall ...
Tracer-aided modelling reveals quick runo generation and groundwater losses producing young stream ow ages in a tropical rainforest catchment
(2021-05-29)
There is still limited understanding of how waters mix, where waters come from and for how long they reside in tropical catchments. In this study, we used a tracer-aided model (TAM) and a gamma convolution integral model ...
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 ...
Tracer hydrology in a hydrometric data-limited and complex tropical mountainous region: the case of the Central American Isthmus
(European Geosciences Union, 2019)
Numerous socio-economic activities are dependent on the seasonal rainfall and groundwater recharge cycle across the Central American Isthmus. Demographic growth and unregulated land use changes resulted in extensive surface ...
Groundwater flow modeling using iMOD for Barva and Colima aquifers in the Central Valley of Costa Rica: validation of a conceptual model using tracer data
(Universidad Nacional de Salta, 2018)
A stationary numerical model of groundwater flow was developed using iMOD to better understand the recharge processes within Barva and Colima aquifers (BCS), located in the northwestern region of the Central Valley of Costa ...
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 ...
Event report: “Green adaptation strategies for water security in the Central American Dry Corridor”. Nicoya, Costa Rica.
(Universidad Tecnológica de Dresde, Alemania, 2019-11)
This document contains the report of the workshop entitled “Green adaptation strategies for water security in the Central American dry corridor” organized in Nicoya, Costa Rica, on 26 March 2019. The workshop represented ...
Nitrate Legacy in a Tropical and Complex Fractured Volcanic Aquifer System
(John Wiley & Sons (Estados Unidos), 2023)
Nitrate legacy is affecting groundwater sources across the tropics. This study describes isotopic
and ionic spatial trends across a tropical, fractured, volcanic multi-aquifer system in central Costa Rica in
relation to ...
Variación Espacial de la Composición de 222RN en los Acuíferos Barva y Colima Superior, Costa Rica
(Universidad de Costa Rica (Costa Rica), 2016)
Radon (222Rn) is a useful natural-occurring tracer to elucidate groundwater to surface water connectivity
with important implications for human health. This study presents the first spatial distribution of 222Rn in ...
