Élaboration d’un cadre chronostratigraphique pour le Pléistocène de la région Centre-Val de Loire (France) : présentation du projet de recherche et des premiers résultats by Céline Coussot, Morgane Liard

“…The stratigraphic correlations observed between the different sequences of each area have revealed the need to establish a regional chronostratigraphic framework for this period, little known until now.A research group, supported by Inrap and made up of geomorphologists and prehistorians working within the framework of preventive archeology, was thus constituted in order to propose a first synthesis of the studied stratigraphies.In the absence of absolute dating, this work relies mainly on facies analogies with reference sequences, established in the Centre-Val de Loire region for alluvial records and in the north of France for silt records.The medium-term objectives are to define regional benchmark horizons that enable the identification of pleistocene stratigraphic sequences from the archaeological survey phase, with a view to the detection of Palaeolithic sites as well as to understand how the major pedological and morphogenic Pleistocene episodes appear within the silt and alluvial superficial formations.…”

Presenting a Geomorphological Conceptual Model of Construction of bridges in urban floodway- river valleys by Esmaiel Najafi, Amir Safari, Ezatoalah Ghavavati, Amir Karam

“…Geomorphology is related to the processes and forms of the earth's surface, and any human activity, including the construction of bridges, leads to quantitative and qualitative changes in the movement and displacement of materials and kinetic energy and affects the geomorphic system, is the concern and involvement of geomorphologists. Geomorphology, as a systematic science can also study and explain the environmental realities that have been objectified in the form of processes and forms in nature, and introduce their results and output spatially in the form of maps and models. …”

GravelSens: A Smart Gravel Sensor for High-Resolution, Non-Destructive Monitoring of Clogging Dynamics by Kaan Koca, Eckhard Schleicher, André Bieberle, Stefan Haun, Silke Wieprecht, Markus Noack

“…Engineers, geomorphologists, and ecologists acknowledge the need for temporally and spatially resolved measurements of sediment clogging (also known as colmation) in permeable gravel-bed rivers due to its adverse impacts on water and habitat quality. …”
