Species Distribution Modelling could be used in the prediction for the assemblage according to the present distribution and environment factors via the Model Maxent and Marxan.

I recommend using the phytoplankton index to assess phytoplankton pollution, and the eutrophication index, then try to use these two indices to explain the dynamics of phytoplankton. another thing, make a comparison between abundance and specific richness in relation to months and seasons, you will find a lot of results to interpret, a multidimentional analysis (acp, acc, afc, ach, for classification of groups and to visualize the interactions between the different species. without forgetting the correlation test, good luck

You could try to use hydrodynamic with water quality models like:

Delft3D - https://oss.deltares.nl/web/delft3d

MOHID - http://www.mohid.com/

Both are open-source models.

There are two methods for fetching phytoplankton samples.

1- Quantitative study method.

2-Qualitative study method.

The quantitative study is that the workplace is determined, taken from the depth of 30 - 40 cm from the surface of the water to the bottom, then submerge the plastic container with a volume of 1 liter, after it is filled we put 3 milliliters of edge material (local solution) is wrapped with a light-proof material and kept Within a temperature of 25 ° C until reaching the laboratory, then the sample is concentrated for 23 days until it becomes 10 milliliters, then the sample is examined on a hemocytometer slide on a microscope under a force of 400.

Renan Ribeiro , Hello ,

how to add a porous plate in the flow (tidal current flow), to simulate the effect of the turbine (energy extraction) in the tidal current flow, in delft3d?

Thanks
