Using Deep Learning AI to Detect Riparian Vegetation Recovery Following a Major Flood in the Brisbane River

River Research and Applications, EarlyView.
ABSTRACT Post‐flood riparian vegetation recovery demands significant attention; however, the complexity of traditional remote sensing methods often hinders environmental managers from implementing rapid vegetation monitoring. This paper developed a model using a Deep Learning Model within ArcGIS to classify and detect recovery of vegetation with high ...

Hydro-geomorphology, sediment transport and human impact in large South American rivers: preface

Latin American Journal of Sedimentology and Basin Analysis, 2021
The research on the hydro-geomorphology, sediment transport and human impact of large rivers has recently increased in South America. The GLOCOPH (Global Commission on Continental Paleohydrology) Working Group on Large Rivers chaired by us, organized ...

How have bridges and culverts changed rivers? A scientometric investigation

Revista Brasileira de Geomorfologia
Bridges and culverts play a crucial role as connectors between river banks. However, these crossing structures alter sediment transport, flow regime, and river morphology.

Use of aerial multispectral images for spatial analysis of flooded riverbed-alluvial plain systems: the case study of the Paglia River (central Italy)

Geomatics, Natural Hazards & Risk, 2017
Image processing and classification techniques are widely used for land use definition. They can also provide interesting applications in fluvial geomorphology, for outlining morpho-sedimentary features (bars, channels, banks and floodplain) at various ...

Mid and Late Holocene evolution of Brateș Lake region (Danube floodplain) based on the multiproxy analysis

Revista de Geomorfologie, 2018
This study proposes a local paleo–landscape reconstruction of the Danube floodplain based on a stratigraphic sequence retrieved from Brateș Lake which, by its emplacement near the confluence of Danube – Prut rivers, was fully receptive to changes ...

Restoring Lateral Connectivity to Anthropogenic Riverscapes: Six Lessons From Stage Zero

River Research and Applications, EarlyView.
ABSTRACT Centuries of river modification, particularly straightening and incision, have severely reduced lateral connectivity between rivers and their floodplains. As a result, Stage 0 riverscapes, characterised by high lateral connectivity (e.g., anastomosing or wetland riverscapes), are now rare in anthropogenic landscapes.

ICESat-2 for Fluvial Geomorphology

, 2022
ICESat-2, a space-borne altimeter launched by NASA in 2018, has the ability to resolve the ground at sub-meter resolution. Using novel filtering techniques and data I/O, we are able to visualize bare-ground transects of heavily vegetated terrain. This presentation was given during the 2022 ESIP January meeting held virtually in January 2022.

Anabranching and maximum flow efficiency in Magela Creek, northern Australia [PDF]

, 2004
Anabranching is the prevailing river pattern found along alluvial tracts of the world's largest rivers. Hydraulic geometry and bed material discharge are compared between single channel and anabranching reaches up to 4 times bank-full discharge in Magela

Application of a Presumptive Standards Approach to Evaluate Environmental Flows in a Highly Regulated River Basin

River Research and Applications, EarlyView.
ABSTRACT The presumptive standards approach to environmental flows offers a method to develop interim guidelines for ecological and social‐cultural flow needs. The approach is based on deriving acceptable percent‐of‐flow limits based on naturalised flows (the absence of depletion or alteration of flow), and it can be an effective precursor to a full ...
