Overview

What is he best known for?

The fields of study he is best known for:

Sedimentary rock
Sediment
Erosion

George Postma mainly investigates Geomorphology, Turbidity current, Geochemistry, Hydraulic jump and Sediment. His Geomorphology study frequently links to related topics such as Quaternary. His Turbidity current research is multidisciplinary, incorporating elements of Clastic rock, Debris flow, Geotechnical engineering, Turbulence and Flow.

His study in Geochemistry is interdisciplinary in nature, drawing from both Abyssal plain and Oceanography. His Hydraulic jump research incorporates themes from Supercritical flow and Bedform. George Postma has researched Sediment in several fields, including Deglaciation and Canyon.

His most cited work include:

Large floating clasts in turbidites: a mechanism for their emplacement (413 citations)
Depositional Architecture and Facies of River and Fan Deltas: A Synthesis (287 citations)
Classification for sediment gravity-flow deposits based on flow conditions during sedimentation (274 citations)

What are the main themes of his work throughout his whole career to date?

George Postma spends much of his time researching Geomorphology, Turbidity current, Sediment, Turbidite and Sedimentary rock. His work in Geomorphology is not limited to one particular discipline; it also encompasses Flume. His Turbidity current study combines topics in areas such as Hydraulic jump, Outcrop, Turbulence, Petrology and Bedform.

His Sediment course of study focuses on Channel and Flow. His work in Turbidite covers topics such as Oceanography which are related to areas like Terrigenous sediment. The Geochemistry study combines topics in areas such as Shear zone and Slumping.

He most often published in these fields:

Geomorphology (45.12%)
Turbidity current (23.17%)
Sediment (19.51%)

What were the highlights of his more recent work (between 2010-2020)?

Geomorphology (45.12%)
Turbidity current (23.17%)
Bedform (12.20%)

In recent papers he was focusing on the following fields of study:

George Postma focuses on Geomorphology, Turbidity current, Bedform, Turbidite and Aggradation. His Geomorphology study incorporates themes from Froude number and Flume. His biological study spans a wide range of topics, including Outcrop, Flow, Petrology, Facies and Mineralogy.

His Petrology research is multidisciplinary, incorporating perspectives in Turbulence, Stratification and Internal flow. His research integrates issues of Hydraulic jump, Channel, Monterey Canyon, Canyon and Supercritical flow in his study of Bedform. The study incorporates disciplines such as Sedimentary depositional environment, Late Miocene and Bouma sequence in addition to Turbidite.

Between 2010 and 2020, his most popular works were:

Morphodynamics and sedimentary structures of bedforms under supercritical-flow conditions: New insights from flume experiments (178 citations)
A comparative study of sediment waves and cyclic steps based on geometries, internal structures and numerical modeling (155 citations)
Key Future Directions For Research On Turbidity Currents and Their Deposits (97 citations)
