Spatiotemporal Dynamics of Flow and Hydrochemistry in Drainage Networks

Despite their high ecological value, non-perennial streams have received less attention than their perennial counterparts. This doctoral thesis addresses this disparity by advancing knowledge on the dynamics of the drainage density and hydrologic processes ...

Nowcasting of High-Intensity Rainfall for Urban Applications in the Netherlands

Guo-Shiuan Lin, Marc Schleiss

Radar rainfall nowcasting has mostly been applied to relatively large (often rural) domains (e.g., river basins), although rainfall nowcasting in small urban areas is expected to be more challenging. Here, we selected 80 events with high rainfall intensiti ...

Towards a metabolic theory of catchments: scaling of water and carbon fluxes with size

Sara Bonetti, Francesca Bassani

Catchments are heterogeneous ecosystems involving several abiotic and biotic processes, where the mutual interactions among water, vegetation, and biogeochemical fluxes take place at different scales. Many biological processes in nature are characterized b ...

Short-term dynamics of drainage density based on a combination of channel flow state surveys and water level measurements

Andrea Rinaldo, Jana Freiin von Freyberg, Izabela Bujak-Ozga

Headwater streams often experience intermittent flow. Consequently, the flowing drainage network expands and contracts and the flowing drainage density (DD) varies over time. Monitoring the DD dynamics is essential to understand the processes controlling i ...

Improved framework to estimate travel time and derived distributions in hydrological control volumes

Mitra Asadollahi

Crossing properties of soil saturation, defined as the duration and excursion of soil saturation below and above certain thresholds, are key variables to ecosystem functioning and evolution by primarily influencing the plant and soil microbes physiological ...

Flexural-tensegrity snapping tails for bio-inspired propulsion in fluids

Pedro Miguel Nunes Pereira de Almeida Reis, Claudio Boni

Many aquatic animals propel themselves by flapping their tails. Leveraging a recently proposed snapping cantilever beam based on the concept of flexural tensegrity, we propose a bio-inspired propulsion device. The design comprises a segmental beam with hol ...

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 ...

Monitoring changes in temporary stream networks during rainfall events

Andrea Rinaldo, Jana Freiin von Freyberg, Izabela Bujak-Ozga, Ilja van Meerveld

Stream networks are important flow pathways along which water transports solutes, sediments and affects living communities. Field observations in headwater catchments have shown that the networks of actively flowing channels are not static, but rather expa ...

An innovative autonomous robotic system for on-site detection of heavy metal pollution plumes in surface water

Bhawna Nagar, Alexander Haider, Qiuyue Yang

Smart monitoring has been studied and developed in recent years to create faster, cheaper, and more user-friendly on-site methods. The present study describes an innovative technology for investigative monitoring of heavy metal pollution (Cu and Pb) in sur ...

Missing water from the Qiangtang Basin on the Tibetan Plateau

David Andrew Barry, Tao Wang, Jiaqi Chen

The Qiangtang Basin is a large endorheic basin in the inner part of the Tibetan Plateau and has been thought to be a dry region in contrast with its wet surrounding outer region that feeds all the major Asian rivers. Combining surface hydrological data wit ...
