Hydrosedimentary dynamics in the Loire Basin" seminar

Quantifying and modelling background load

ZAL "Transfers" Thematic Group

7 September 2021 from 9 a.m. to 12.30 p.m. - off-line

The ZAL's "Transfers" thematic group, led by Nathalie Gassama (University of Tours), Malgorzata Grybos (University of Limoges) and Stéphane Braud (DREAL for the Loire-Bretagne basin), is organising its first seminar on the subject of hydrosedimentary dynamics in the Loire basin. During this half-day event, researchers and managers will present a range of work on the Loire and its tributaries. This seminar will take place remotely.

Free and compulsory registration
