摘要：The Neretva river springs in high dinaric karst and with its current intersects it vertically and flows into the Adriatic sea. From the place of Počitelj it becomes lowlands river which through deposition of fluvio-glacial and alluvial material flooded karst basins in the lower stream and created a delta 40 km long and 5 – 10 km wide. The Neretva delta is divided with slopes of Biokovo (Rilići) and Gabelska greda on two different units: the Upper-Neretva delta or Svitavsko blato and lake Deransko (Hutovo blato) within borders of Bosnia and Herzegovina, and the Lower-Neretva delta within borders of Croatia, which is the subject of this work. Lower-Neretva delta can be divided according to a Conditional-Homogenous regionalization and criterium of natural elements into six micro-units: Vidovsko blato, Vrbovci – Koševo, Kuti, Luke, Rogotin – Ušće and Opuzen – Ušće. According to criterium of socio-cultural and un-migrated areas it can be divided into four micro-units: Karst – limestone frame (mountain area), bordering area (contact between karst and swamp), alluvial plane (flow of the Neretva and the Mala Neretva) and seafront. According to nodal-functional regionalization and central settlements it can be divided into three units: the area of Metković, Opuzen and Ploče.
