Advancing ecohydrology in the 21st century: A convergence of opportunities

Andrea Rinaldo, Nicolaas Cornelis van de Giesen, Gabriel George Katul

Nature-based solutions for water-resource challenges require advances in the science of ecohydrology. Current understanding is limited by a shortage of observations and theories that can further our capability to synthesize complex processes across scales ...

Evaporation from cultivated and semi-wild Sudanian Savanna in west Africa

Marc Parlange, Natalie Claire Ceperley, Theophile Mande, Nicolaas Cornelis van de Giesen

Rain-fed farming is the primary livelihood of semi-arid west Africa. Changes in land cover have the potential to affect precipitation, the critical resource for production. Turbulent flux measurements from two eddy-covariance towers and additional observat ...

An information-theoretical perspective on weighted ensemble forecasts

Nicolaas Cornelis van de Giesen, Steven Vincent Weijs

This paper presents an information--theoretical method for weighting ensemble forecasts with new information. Weighted ensemble forecasts can be used to adjust the distribution that an existing ensemble of time series represents, without modifying the valu ...

Data compression to define information content of hydrological time series

Marc Parlange, Nicolaas Cornelis van de Giesen, Steven Vincent Weijs

When inferring models from hydrological data or calibrating hydrological models, we are interested in the information content of those data to quantify how much can potentially be learned from them. In this work we take a perspective from (algorithmic) inf ...

HydroZIP: How Hydrological Knowledge can Be Used to Improve Compression of Hydrological Data

Marc Parlange, Nicolaas Cornelis van de Giesen, Steven Vincent Weijs

From algorithmic information theory, which connects the information content of a data set to the shortest computer program that can produce it, it is known that there are strong analogies between compression, knowledge, inference and prediction. The more w ...

Carbon monoxide as a tracer of gas transport in snow and other natural porous media

Marc Parlange, Marc Calaf Bracons, Wolf Hendrik Huwald, Scott W. Tyler, Nicolaas Cornelis van de Giesen

The movement of air in natural porous media is complex and challenging to measure. Yet gas transport has important implications, for instance, for the evolution of the seasonal snow cover and for water vapor transport in soil. A novel in situ multi-sensor ...

Distributed fiber-optic temperature sensing for hydrologic systems

Luc Thévenaz, Marc Parlange, Wolf Hendrik Huwald, Nicolaas Cornelis van de Giesen

Instruments for distributed fiber-optic measurement of temperature are now available with temperature resolution of 0.01°C and spatial resolution of 1 m with temporal resolution of fractions of a minute along standard fiber-optic cables used for communicat ...

Fiber optics opens window on stream dynamics

Marc Parlange, Nicolaas Cornelis van de Giesen

A new approach to monitoring surface waters using distributed fiber optic temperature sensing is presented, allowing resolutions of temperature of 0.01°C every meter along a fiber optic cable of up to 10,000 m in length. We illustrate the potential of this ...
