Hello
I am currently working on a survey of a bay . during the excavation task in order to construct a drainage network , water level from the sea has rose up in one trench as shown in these pictures .

Now i know common solutions requires the use of poorly graded gravel and or special cement. I would be happy if you direct me into case studies or books that relates to this problem.

How do you plan to drain anything by gravity when the level of the bottom of the trench is below sea level? Pumps?

pumps are out of the question, could you pump up the whole sea !
