Characterization of surface water isotope spatial patterns of Scotland
(Elsevier B.V., 2018-07-24)
The extended National Waters Inventory of Scotland (NWIS) monitoring network in combination with an extensive, supplementary low flow sampling campaign was used to create isoscapes of surface water for management purposes ...
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 ...
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 ...
DOC Transport and Export in a Dynamic Tropical Catchment
(American Geophysical Union, 2019)
Abstract Dissolved organic carbon (DOC) transport and export from headwater forests into freshwaters in highly dynamic tropical catchments are still understudied. Here we present a DOC analysis (2017) in a
pristine and ...
Headwaters drive streamflow and lowland tracer export in a large-scale humid tropical catchment
(John Wiley and Sons Ltd, 2020)
Headwaters are generally assumed to contribute the majority of water to downstream users, but
how much water, of what quality and where it is generated are rarely known in the humid tropics.
Here, using monthly monitoring ...
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 ...
End member and Bayesian mixing models consistently indicate near-surface flowpath dominance in a pristine humid tropical rainforest
(John Wiley & Sons Ltd, 2021)
The impacts of forest conversion on runoff generation in the tropics have received much
interest, but scientific progress is still hampered by challenging fieldwork conditions and
limited knowledge about runoff mechanisms. ...
A preliminary isotope-based evapotranspiration partitioningapproach for tropical Costa Rica
(John Wiley and Sons Ltd, 2021-07)
Spatially and seasonally distributed information on transpiration (T) fluxes is limited in the tropics. Here, we applied a coupled isotope mass balance model to separate water fluxes of T and evapotranspiration (ET) from ...
Modelling non-stationary water ages in a tropical rainforest: A preliminary spatially distributed assessment
(John Wiley and Sons Ltd, 2020)
Pristine tropical forests play a critical role in regional and global climate systems. For a
better understanding of the eco-hydrology of tropical “evergreen” vegetation, it is
essential to know the partitioning of water ...
