Rising water table

Rising water table

Rising water table

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.

RE: Rising water table

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

RE: Rising water table

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