Did you know... that the groundwater level of a coastal aquifer system changes with the tide?

Recommendations for improvement
1. More explanation could be added in the description columns for different types of aquifers. For example, in the ‘unconfined continental coastal aquifer’ part, how water flows within the transition zone? If you are afraid that might be too wordy, you can treat this table as a summary table and more details could be written in paragraph form.
2. The sentence ‘suppose the rock is homogeneous in the different models so that the hydraulic conductivity is uniform’ should be put at top of the table since it is an assumption for different types of aquifers.
3. It would be great if the diagram can be enlarged a bit for easier reading since the diagrams are important to assist readers to understand the concept you wanna bring out.
4. Overall, the content is detailed, clear and easy to understand. There are also quite a lot of diagrams provided to assist my understanding.
1. Brief explaination on how an aquifer works in coastal areas might help introduce the section about different aquifer types
2. Colouring all diagrams in the "Freshwater-Seawater Interface in Coastal Aquifers" section would definetly help visualise the position of the interface.
3. It might be helpful to label diagrams in numbers and refer to them in text. Since there are many diagrams, this might help readers find the relevant diagrams more easily.
1. For the figure next to Seawater Intrusion Section and the modified Schmorak and Mercado(1969) figure, it may be better to add the word 'pumping' next to the well like what you did for other figures.
2. I cannot quite follow when 'tidal efficiency' is mentioned in that section. Can you elaborate more on that?
3. There are some grammatical errors (I'm not a 100% sure about these):
a. the first two sentences of the last paragraph of the introduction should be combined.
b. 'Ghijben – Herzberg Principle purposed...' proposed?
c. Hard rock *aquifers* are composed of...
d. Sentences in the Well Design Improvements section
4. the fonts in some figures are a bit small or unlcear, e.g., Figure C of Seawater Intrusion and the figure modified from Jiao and Post (2019).
Some word choices may be a tad bit weird eg. Hard Rock Aquifer - "Hard rock aquifer composites of
igneous rock or
metamorphic rock or both." would be preferable if "composite" were replaced by "are composed"
Some very minor grammar issues eg. Hard Rock Aquifer - "Low porosity hard rock with different orientation of
joints and
fractures provides space..." "Groundwater flowsflow direction is controlled by..." Limestone Aquifer - "
Limestone aquifer is an aquifer that is made of
carbonate mineralseither marine limestone or
bioclastic limestone." I would suggest you to either remove "carbonate minerals either" or replace "either" with ", namely". "Fine-grained limestone ishas low
porosity and
permeability while
bioclastic limestone is an opposing casethe opposite/ antithesis. Seawater Intrusion - "
Seawater intrusion is defined as a process that freshwater aquifer becomes salinized due to..." a verb/ action should follow "that" eg. "
Seawater intrusion is defined as a process that salinizes freshwater aquifer due to.." alternatively you could change "that" to "where/ in which". There are some more trivial errors but I won't bore you with my grammar policing (I teach kids English as a part-time job and I've been told I can be a bit obnoxious lol) I won't mind doing a proof-read for you before the live Wikipedia, should I find the time...
I love how you used LOADS of diagrams (I'm a sucker for diagrams), I'm also a sucker for larger and colorful diagrams (meaning I'd like you to increase the size and color the diagrams).
In the tidal section you mention "Tidal efficiency of the magnitude of the oscillation of water level in a well to the oscillation of sea level is about 42%-44%": I don't know what you mean by this, and is this just one example rather than a general statment?
The section "Chemical processes in coastal aquifer" covers a bit, but there appears to be more in the diagram unmentioned in text.
Are the lifeforms in these aquifers out of scope for this topic? I seem to remember a tiny animal lived between gains in the transition of salt-fresh.
Is this hydrology studied by any geophysical methods, such as electrical conductivity or ground penetrating radar, or only by looking in wells and springs?
For some diagrams, where the text cannot be read because it is too small, you could increase the font size. Also if you can use
.svg format for your diagrams, they could then be translated into other languages more easily.
