Confluence Dynamics in a Modelled Large Sand-Bed Braided River

Longitudinal variability in hydraulic geometry and substrate characteristics of a Great Plains sand-bed river

DTM and interpolations in GRASS: application to a braided river

The present work deals with the problems related to the generation of Digital Terrain Model (DTM) of braided rivers by means of the open source GIS GRASS. In particular, we investigated how to optimize the terrain survey, that is how to reduce the density of topographic points that we have to survey and which is their best distribution, related to the employed interpolation method and with resp...

A braided cancer river connects tumor heterogeneity and precision medicine

With the ever-increasing complexity of tumor heterogeneity (TH) discovered through cancer genome sequencing, it is apparent that TH has become the biggest hurdle for precision cancer therapeutics. Through studying the genomics of exceptional responders to targeted therapeutic agents in kidney cancer, we demonstrated parallel convergent gene/pathway/capability/function evolution of kidney cancer...

Metric-Resolution 2D River Modeling at the Macroscale: Computational Methods and Applications in a Braided River

Metric resolution digital terrain models (DTMs) of rivers now make it possible for multi-dimensional fluid mechanics models to be applied to characterize flow at fine scales that are relevant to studies of river hydraulic geometry (HG) and ecological habitat, or microscales. These developments are important for managing rivers because of the potential to better understand system dynamics, anthr...

Fine Sediment Infiltration Dynamics in a Gravel-bed River following a Sediment Pulse

Pulses of fine sediment in gravel-bedded rivers can cause extensive fine sediment infiltration (FSI) into void spaces in coarse bed material, potentially altering river morphodynamics and aquatic ecosystems. Previous work suggests a conceptual model of FSI whereby FSI occurs to a limited depth as a function of the relative grain size of bed sediment compared with infiltrating sediment and is in...
