If you have an agency that maps soils, you will probably get much of the information from the soil map and the soil type descriptions of your area.  Most of those items you mentioned may be addressed. If you have an ecological classification and mapping (this may be called zoning, I suppose) of the area, it also should find much information  that would interest you.  It imay be very similar to soil map, but ecological mapping By ecologists, has a tendency to rely on plants.  Soil scientists map soils, ecologists who are also botanists map plant associations.  Soil, geology, vegetation, hydrology, salinity range, flooding, suitability for various uses, limitations, typical fauna, and possibly go into detail of native plant and animal species.  Climate, rainfall and runoff may be considered in the descriptions, or like many other things, the boundaries of the zones.

Tides are responsible for formation of ecological zonation or intertidal zonation in the mangrove forests. So, near water front true mangrove species occupy followed by other assoicate mangroves. Away from the water front and near to the terrestial habitat, halophytes are present where  water touch this region during high tides of the sea only. And soil charasterstics and salinity of soil vary from water front to land ward zone. Canopy and height of the mangrove species also varied from water front to land ward region. I am giving some references for your information 

Thank you
