Generalization of an Encoder-Decoder LSTM model for flood prediction in ungauged catchments

Olga Fink, Yi Zhang, Peter Molnar, Silvan Ragettli

Flood prediction in ungauged catchments is usually conducted by hydrological models that are parameterized based on nearby and similar gauged catchments. As an alternative to this process-based modelling, deep learning (DL) models have demonstrated their a ...

More green and less blue water in the Alps during warmer summers

Gabriele Manoli, Peter Molnar, Paolo Burlando

Climate change can reduce surface-water supply by enhancing evapotranspiration in forested mountains, especially during heatwaves. We investigate this ‘drought paradox’ for the European Alps using a 1,212-station database and hyper-resolution ecohydrologic ...

Matching ecohydrological processes and scales of banded vegetation patterns in semiarid catchments

Gabriele Manoli, Gabriel George Katul, Peter Molnar

While the claim that water-carbon interactions result in spatially coherent vegetation patterning is rarely disputed in many arid and semiarid regions, the significance of the detailed water pathways and other high frequency variability remain an open ques ...

Ecomorphodynamics of rivers with converging boundaries

Paolo Perona, Benoît Crouzy, Peter Molnar

Many rivers worldwide show converging sections where a characteristic limiting front for vegetation establishment on gravel bars is observed. An important conceptual model was advanced in 2006 by Gurnell and Petts, who demonstrated that for the convergent ...

Vegetation establishment in convectively accelerated streams

Paolo Perona, Benoît Crouzy, Peter Molnar

We study the conditions for vegetation establishment within river reaches with converging boundaries. Common to many such rivers worldwide is the existence of a limiting front (e.g., Figure 1a) beyond which all the riverbed vegetation is uprooted by floodi ...

Biomass selection by floods and related timescales: Part 1. Experimental observations

Paolo Perona, Benoît Crouzy, Katharina Maria Edmaier, Peter Molnar, Zhe Jiang

Several research investigations have explored the interaction between morphodynamic and vegetation growth processes from both the modelling and the experimental viewpoints. Results have mainly been concerned with morphologic analyses of the effects of vege ...

Modelling river and riparian vegetation interactions and related importance for sustainable ecosystem management

Paolo Perona, Peter Molnar

We discuss the importance of modeling riparian vegetation and river flow interactions under differing hydrologic regimes. Modelling tools have notable implications with regard to the understanding of riverine ecosystem functioning and to promote sustainabl ...

An experimental comparison of silica gel and quartz sand grains as sediment media for growing vegetation at the laboratory scale

Paolo Perona, Peter Molnar, Zhe Jiang

In this technical note we compare silica gel grains and quartz sand as sediment media for vegetation root growth in laboratory experiments for ecohydrology and ecohydraulics. Silica gel grains become quite transparent when saturated with water. This would ...

An observation-based stochastic model for sediment and vegetation dynamics in the floodplain of an Alpine braided river

Paolo Perona, Peter Molnar

Riparian vegetation dynamics in Alpine rivers are to a large extent driven by the timing and magnitude of floods which inundate the floodplain, transport sediment, erode the river bed, and create and destroy suitable germination sites. Here we present a st ...
