Publikováno v: Søe, N E, Kroon, A, Odgaard, B V, Lykke-Andersen, H & Kristiansen, S M 2018, ' Bathymetric control of Holocene spit migration in a lacustrine environment ', Holocene, vol. 28, no. 8, pp. 1245-1254 . https://doi.org/10.1177/0959683618771498

Wave processes are well known for developing spit systems in large or elongated lakes by inducing longshore sediment transport for spit migration, while bathymetric interaction is less studied. In this study, we investigate the combined effects of wa

Publikováno v: Physics and Chemistry of the Earth, Parts A/B/C. 36:1386-1397

Airborne electromagnetic methods (AEM) are used extensively in groundwater investigations, often in combination with high-resolution seismic data. Despite the frequent use of this mapping strategy, only a few cases are found in the literature. In thi
