Mitigating the Negative Impacts of Caspian Sea Level Fluctuations On Coastal Infrastructure

Natural fluctuations of the Caspian Sea level create many problems for its coastal infrastructure, complicate navigation and fishing, and negatively affect the ecological situation both in the coastal zone and in the coastal water area.It is necessary to deal with a complexity in a sea area alteration very carefully in order not to destroy the fragile ecological balance of coastal flora and fauna.To reduce the negative consequences of a northern water area shoaling of the Caspian Sea, a dredging is constantly carried out, which requires a careful planning due to a constant variability of the sea area boundaries.Taking into account this fact, the problem of permanent monitoring of newly formed closed water bodies with the help of autonomous water drones that allow to quickly build a 3d model of the water body for dredging planning becomes urgent.As a rule, such bodies of water are formed far from large settlements and energy sources, and the process of surveying the water body can stretch in time, so the problem of recharging the batteries of the drone becomes very relevant and is solved with the help of solar panels.The data received from the distance sensors can be noisy, so they are subjected to a de-noising procedure.
