Details of Kolkheti coastal dynamic system


Dataset identification

Title of datasetKolkheti coastal dynamic system
Narrative summary of datasetThe objective of research was to study Poti - Supsa Coastal Line Changes ( Grigoleti area) using all existing data (including historical ), aiming to reveal development of river Rioni new delta (Nabada) and Poti sea port entrance channel sedimentation processes. The old maps (from 1957 to 2016) of river Rioni new delta (Nabada) were retrieved from the Poti sea port archive, which were referenced to the new Gamma Consulting ltd produced maps, transformed to UTM-37N projection, maps were referenced by visual orienteers.
Summary of processing methodologyExisting and field survey data were recalculated using geodesic calculator to geographic WGS-84 and rectangular coordinate system –zone 37N.
Project/programmeAn assessment and forecasting of the Georgian Black Sea shore development
Start date1957-01-01
