The investigation of dangerous marine phenomena in the coastal zone based on the field observations results

Abstract

A review of the results obtained based on long-term observations of hydro-and meteorological parameters, carried out for many years IMGG FEB RAS. One of the main objectives of the research field of the wave variability in the coastal zone is the experimental study of marine hazards in the coastal zone, which may represent a serious threat to the coastal settlements. IMGG FEB RAS holds the full cycle investigations of wave parameters at the coastal area till the creation of instruments to the measurement and software systems for the analysis of the results to the direct analysis of the field data.

Development of the dual-channel frequency meter for measurements with hydrostatic pressure sensor

“…As a result, the system can record all the data in real time with further transmission of the information for analysis. In contrast to the AWR, the advantage of the cable system is no loss of the recorded data with losing the sensor, which may occur due to sea waves, ice and other reasons [2]. However, the cable system requires a communication line between the sensor and the coastal measuring construction and, considering the lack of the power supply system in coastlines, it must have a backup power source.…”

“…In order to make the measuring process less complicated, we should decrease the amount of cables used for communication and powering the sensors. To simplify the problem, it is recommended to use the frequency output sensors, which can be connected with one coaxial load-bearing cable [3]. Meteorological condition must be taken into account with wave registration, which results in using meteorological station, that also requires its own power supply making it more difficult to install the measuring equipment.…”
