Along three rivers at the Mendocino triple junction, northern California, strath, cut, and fill terraces have formed in response to tectonic and eustatic processes. Detailed surveying and radiometric dating at multiple sites indicate that lower reaches of the rivers are dominated by the effects of oscillating sea level, primarily aggradation and formation of fill terraces during sea level high stands, alternating with deep incision during low stands. A eustasy-driven deposi- tional wedge… Expand

Fluvial terrace formation in the lower Awhea and Pahaoa River valleys, New Zealand: implications for tectonic and sea-level controls
Abstract Altitudes and ages of fluvial terraces along the lower Awhea and Pahaoa River valleys are compared with the altitudes and ages of Holocene marine deposits and terraces in the activelyExpand

River incision into bedrock resulting from the combined effects of tectonic uplift and climate governs long-term regional landscape evolution. We determined spatial and temporal patterns ofExpand
Numerical modeling of fluvial strath-terrace formation in response to oscillating climate
Many river systems in western North America retain a fluvial strath-terrace rec ord of discontinuous downcutting into bedrock through the Quaternary. Their importance lies in their use to interpretExpand

Dating the Tejo river lower terraces in the Ródão area (Portugal) to assess the role of tectonics and uplift
Abstract The Tejo river is one of the major drainages in Iberian Peninsula; it is a long-lived system (ca. 3.4 Ma) and provides an archive of long-term landscape development and environmental changeExpand
Quantification of fluvial incision in the Duero Basin (NW Iberia) from longitudinal profile analysis and terrestrial cosmogenic nuclide concentrations
The Duero Basin is one of the largest Cenozoic basins in Iberia and contains a relatively well-preserved sedimentary infill. The top of the sedimentary sequence crops out at elevations up to 900 mExpand
Stochastic alluvial fan and terrace formation triggered by a high-magnitude Holocene landslide in the Klados Gorge, Crete
Abstract. Alluvial fan and terrace formation is traditionally interpreted as related to Quaternary climate oscillations under the backdrop of slow and steady tectonic activity. However, severalExpand
