Special Issue Information
Dear Colleagues,
The purpose of this Special Issue of Geosciences is to provide original research articles in the field of geomorphology, earth surface processes, and climate–tectonic interactions focused on transient landforms and transient stages of landscapes.
The Earth’s topography results from the interaction between deep tectonic processes and erosional processes, which theoretically evolve toward a so-called “steady state” stage when tectonic uplift is balanced by erosion. One of the current challenges in geomorphology is to characterize the “transient landscapes” from the steady state ones and interpret their origin. Numerous recent studies have shown that transient stages represent some large, and sometimes unsuspected, periods of the evolution of the Earth's topography. However, the complexity of the relationships between the uplift processes and the erosional response of the geomorphic systems which operate at different timescales (104 to 106 years) and length scales (1-1000’s km including fluvial, hillslope, or colluvial scales) does not easily allow one to extract the relative impact of tectonics, climate, and biology from landforms and their erosional products.What are the response times of the geomorphic systems? Can we estimate the nature, magnitude, and timing of forcing parameters? What are the couplings and feedback mechanisms between surface erosion, climate, and tectonic processes? The answer to these questions can be found in innovative works including detailed interpretations of modern geomorphic parameters coupled with modeling and/or analytic approaches. A case-by-case basis is expected to allow to distinguish among surface uplift and climate influence on transient landscapes. These case studies can give important constraints on the spatiotemporal evolution of past and active tectonics, and on the response of geomorphic systems following major climate changes.
Authors are invited to submit their work focusing on the following topics:
-Geomorphological or geological field studies possibly combined with SIG maps and geobrowser tools;
-Transient river long profiles and knickpoint migration analyses linked to base-level changes or active tectonic areas;
-Response time, drainage network dynamics, and the interplay between fluvial, hillslope, and mass movement processes associated with transient landscapes;
-Numerical/experimental modeling of landscapes;
-Mid- to long-term erosional budget and associated topographic evolution constrained by thermochronology, cosmogenic isotopes, optically stimulated or infrared stimulated luminescence, paleoelevation data and other analytic approaches.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Geosciences is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
