Thermodynamics in the hydrologic response: Travel time formulation and application to Alpine catchments

Andrea Rinaldo, Michael Lehning, Bettina Schaefli, Francesco Comola

This paper presents a spatially-explicit model for hydro-thermal response simulations of Alpine catchments, accounting for advective and non-advective energy fluxes in stream networks characterized by arbitrary degrees of geomorphological complexity. The r ...

Using Heat as a Tracer to Characterize Streambed Water Fluxes of the Brenta River (Italy)

Andrea Rinaldo

This work deals with the characterization of the spatial and temporal variability of water exchange fluxes from/to the Brenta river streambed (Veneto, Italy), critically important to regional water resources management. The aquifer system is structurally q ...

Non-stationarity in experimental travel time measured in a lysimeter: theoretical and modeling lessons from a simplified hydrological system

Andrea Rinaldo, Enrico Bertuzzo, Pierre Claude Jean Queloz, Luca Carraro, Gianluca Botter

Experimental data have been collected over a year-long period in a large weighing lysimeter. Natural climatic forcing occurs, except for rainfall which is artificially generated as a given Poisson process at a daily timescale. A constant water table is mai ...

The importance of hydraulic groundwater theory in catchment hydrology: The legacy of Wilfried Brutsaert and Jean-Yves Parlange

Alexis Berne

Based on a literature overview, this paper summarizes the impact and legacy of the contributions of Wilfried Brutsaert and Jean-Yves Parlange (Cornell University) with respect to the current state-of-the-art understanding in hydraulic groundwater theory. F ...

Hydrology of the Sudanian Savannah in West Africa, Burkina Faso

Theophile Mande

As in all semi-arid regions, Tambarga, a small village surrounded by national parks in the landlocked country of Burkina Faso, is affected by the seasonality of the local hydrology. Seasonal and spatial variability of rainfall shapes the livelihoods of rur ...

Capillary Effects on Groundwater Waves in Unconfined Coastal Aquifers

David Andrew Barry

Various types of Boussinesq model exist, including those that account for finite-depth aquifers and capillary effects. Such models are used to simulate propagation of groundwater waves (watertable fluctuations) due to, for example, tides. However, discrepa ...

Modelling migration and dissolution of mineral particles in saturated porous media

David Andrew Barry, Christof Holliger, Alessandro Brovelli, Elsa Marina Lacroix

Understanding and predicting the fate in soils and other porous media of solid mineral particles with grain diameters in the micrometer range is important in a number of environmental and civil engineering applications, including subsurface hydrology, wast ...

Sustainable soil and water resources: modelling soil erosion and its impact on the environment

David Andrew Barry

With the projected increase in world population to 9 billion by 2050, along with per capita income growth, the demand for land and water resources is going to increase significantly. Conversion of land to intensive agriculture has led to dramatic decreases ...

Stream temperature modeling using fiber optic distributed temperature measurements in a sub-Saharan watershed, Burkina Faso

Malik Matthey

High spatial and temporal resolution water temperature measurements, using DTS, allow to model and to control stream temperature evolution in the Tambarga’s basin (Burkina Faso). A wireless sensor network recorded solar radiation, air temperature, air humi ...

Modeling groundwater and benzene discharge to a river from an alluvial aquifer subject to strong interactions with surface water

Jordi Batlle-Aguilar

Modeling groundwater flow and contaminant transport in industrialized and urbanized alluvial plains is challenging because of the dynamic nature of the strongly interacting river – groundwater system and the scarcity of data. An original combined regional ...
