DKup24-landhævningsmodel for Danmark

https://doi.org/10.54337/ojs.perspektiv.v24i49.10878Resumé
En regional model af vertikale landbevægelser for Danmark er udviklet med geodætiske data fra de sidste godt hundrede år. Modellen beskriver deformationer i det nationale højdesystem og muliggør en dynamisk fremskrivning af DVR90. Modellen bidrager endvidere i vurderinger af effekterne af fremtidige klimaforandringer i planlægning af infrastruktur and kystbeskyttelse.
Modellen er beregnet ved hjælp af en empirisk metode ud fra data fra de tre nationale præcisionsnivellementer, vandstandsmålere og permanente GNSS-referencestationer. NKG2016GIA-modellen udviklet af Steffen et al. (2016) anvendes som reference-model. Modellen beskriver ændringer i perioden 1900-2000.
