Investigating the waters' flushing of the inner basin of nea Moudania harbor (northern Greece)

Abstract

The harbour of Nea Moudania lies at the southeastern coasts of the external Thermaikos gulf

and constitutes one of the most important harbours of the Northern Greece. The great importance of

the harbour in combination with its imminent extension raises the need of a thorough investigation of

its hydrodynamics. The study of the waters’ flushing between the inner and outer basin of the harbour

constitutes the objective of this work. For this purpose, field research was realised, including current

measurements in the port entrance as well as pressure – water level data recordings. Meteorological

data have been also collected and studied. The analysis of the collected data led to flushing flow

rates of a few m3

of one order of one day, with mean annual value of 0.7 days. These values were taken into account

for the estimation of the self-purification capacity of the harbour inner basin.
