Abstract
Ice jams are dangerous hydrological phenomena characteristic of most rivers of Russia. To reduce the risk of flooding of settlements during the spring flood, the development of technology for integrated monitoring of the river ice cover, based on the methods of GPR and the Earth remote sensing (ERS), is proposed. The advantage of the technology is the ability to obtain detailed information in vast and inaccessible areas with a bleak climate. The results of an experimental study of a site of 0.4 km2 in the Khatystakh arm of the Lena River are presented. The OKO-2 GPR (Logis-Geotech group of companies, Russia) determined the thickness and structure of the ice cover. Satellite images determined the tonal characteristics of the ice cover in contact with sand and water. The combination of GPR results and ERS images made it possible to obtain detailed information about the spatial change in the thickness and structure of the ice cover. The prospect of integrated information lies in the possibility of integral assessments, and their use in modeling, monitoring and forecasting ice conditions in the spring.
