Abstract Water transit time is now a standard measure in catchment hydrological and ecohydrological research. The last comprehensive review of modeling approaches was published 15+ years ago. But since then the field has largely expanded with new data, theory applications. Here, we these developments focus on water‐age‐balance data‐based approaches. We discuss compare methods including StorAge‐Selection functions, well/partially mixed compartments, water age tracking through spatially...
Abstract Catchment travel times integrate the multitude of hydrological flow processes and provide insights into catchment functioning. StorAge Selection (SAS) functions describe how residence water in storage are related to outflows. As such, SAS useful summarize transport catchments ideal simulate outflows concentrations various solutes tracers. Recent studies suggested that using one probability distribution function (pdf) for may not account all systems. In this study we introduced a...
Abstract Recent studies on the relationships between catchment storage and water ages using Travel Time Distributions (TTDs), Residence (RTDs), StorAge Selection (SAS) functions have led to hypothesis that streamflow preferentially mobilizes younger when is high. This so‐called “Inverse Storage Effect” (ISE) needs further evaluation in more catchments with diverse climates physiographical features. In this work, we assessed validity of ISE WS10 (H. J. Andrews forest, Oregon, USA), a forested...
Abstract. Catchment travel time distributions (TTDs) are an efficient concept for summarizing the time-varying 3D transport of water and solutes towards outlet in a single function age estimating catchment storage by leveraging information contained tracer data (e.g., deuterium 2H tritium 3H). It is argued that preferential use stable isotopes O H as tracers, compared to tritium, has truncated our vision streamflow TTDs, meaning long tails distribution associated with old tend be neglected....
Abstract Travel time distributions (TTDs) are concise descriptions of transport processes in catchments based on water ages, and they particularly efficient as lumped hydrological models to simulate tracers outflows. Past studies have approximated catchment TTDs with unimodal probability distribution functions (pdf) successfully simulated outflows those. However, intricate flow paths contrasting velocities observed complex systems may generate multimodal age distributions. This study...
Abstract. Catchment travel time distributions (TTDs) are an efficient concept to summarize the time-varying 3-dimensional transport of water and solutes outlet in a single function age estimate catchment storage by leveraging information contained tracer data (e.g. 2H 3H). It is argued that increasing use stable isotopes O H compared tritium as tracers has truncated our vision streamflow TTDs, meaning long tails associated with old neglected. However, reasons for truncation TTD still...
<p>Catchment travel time distributions (TTDs) are an integrative measure of time-varying flow paths and hydrological processes, commonly derived from tracer data (e.g. 2-H, 3-H). Recently, it has been argued that the use stable isotopes O H compared to tritium neglects long tails TTDs thus truncates our vision on streamflow age. However, reasons for truncation TTD remain obscured by methodological limitations, including different mathematical models sampling strategies. In this...
Wasser, das durch hydrologische Landschaften (wie Einzugsgebiete) fliest, benotigt unterschiedlich lange, um den nachsten Fluss zu erreichen. In anderen Worten: Wasser im besteht aus einer Verteilung von verschiedenen Alters. Transitzeitverteilungen (engl.: Travel Time Distributions (TTDs)) charakterisieren die Transitzeiten des Wassers bis zum Abfluss einem Einzugsgebiet und beschreiben, wie Einzugsgebiete speichern abgeben, vor Tagen, Monaten Jahren als Niederschlag gefallen ist....
<p>Vegetation exhibits critical feedback with runoff generation. Trees show distinct water uptake patterns relying on soil from different depths and groundwater a mixture of sources that is commonly very in terms age distribution isotopic composition. Here we present multi-method multi-model approach to study the spatio-temporal sap flow tree streamflow headwater catchment (mixed forest, 43 ha). For this, monitored spatially distributed at >30 trees over two years,...
