-    Evaluate the basic characteristics of sedimentary environment in intertial ecosystem of Red River Delta (geomorphology, dynamics and material composition);
-    Clarifying the role of sedimentary environment for intertidal ecosystem of Red River Delta, proposing solutions for protection and restoration.

Theoretical results:
The project has analyzed and synthesized classification of intertidal zone and intertidal ecosystems.
The project has identified the role of the sedimentary environment for the intertidal ecosystems in intertidal zone of Red River Delta, including:
-    Sedimentary environment plays an important role for distributions of intertidal ecosystems in intertidal zone of Red River Delta.
-    Sedimentary environment plays an important role in the ecological succession of intertidal ecosystems of Red River Delta.
Applied results:
Based on results of project for proposing restoration and development of intertidal ecosystems in Red River Delta.

The project determined how to divide intertidal zone and intertital ecosystem;
The project identified the role of sedimentary environment for the intertital ecosystem of Red River Delta.
