@udhavmaharaj It is an amazing method of bathymetry collection. An evaluation in Lærdal: mdpi.com/2072-4292/15/1…

@AlfKnut Amazing, how did the data compare to traditional methods?

A model of Lærdal river. High precision Green and red LiDAR bathymetry provides an amazing foundation for building hydraulic models.

@udhavmaharaj The measurements were done by the Austrian company AHM, and I think they used the Riegl VQ-880.

@AlfKnut Which sensor did you use ?

Is #hydropeaking of rivers disrupting your favourite summer pastimes? 🛶 SEI's @faisalashraf25 and colleagues studied how energy demands affect socio-recreational ecosystem services (SRESs), using 🇫🇮's Kemijoki River as a case study. 🔗buff.ly/41XClEZ @SciTotEnv

@altorabi1 Congratulations.

@EliisaSelina @SuomenAkatemia The same place in winter

Research visit to NTNU, Trondheim, has started with frazil ice and ice run observation site visits. ☀️💧#DefrostingRivers @SuomenAkatemia

@SterudErik @arildhermstad @BaneNORSF @Presserom For jernbane er det vel 200 år som er dimensjonerende flom i dag. Det same gjeld for vegar med høg trafikk og vanskeleg omkøyring. viewers.vegnorm.vegvesen.no/product/859942…

Nå er det umulig å komme seg med tog mellom Trondheim og Oslo. Rørosbanen er stengt pga styrtregn, mens Dovrebanen er stengt på ubestemt tid. Kan @BaneNORSF bruke anledningen til å ruste Dovrebanen mot klimaendringen. nrk.no/trondelag/roro…

@SterudErik @trondstenvik Har nasjonalt laksevassdrag nokon gong fungert som vern mot inngrep i vassdrag?

Still some ice on Tornionjoki

@PerttiScience @alirezasharifig @altorabi1 @AbolfazlJalali Very interesting two days seeing new rivers and discussing ice monitoring strategies. I hope to come back in winter to see the ice.

@alirezasharifig @altorabi1 @AlfKnut @AbolfazlJalali Nice to see you out with #CRYO_RI crew, unlucky I could not join..

Good day with @altorabi1 , @AlfKnut and @AbolfazlJalali Field visit for the measuring ice thickness project.
