1. The problem statement, all variables and given/known data
So I am currently in my final year working on my thesis. Below is the details of my thesis topic:
Metacentric height (Computational)

It is a simple matter to determine whether a body will float in a liquid, it is not so easy to determine the orientation at which the body will float or the stability of the body in that position. The student undertaking this project will develop a computer program which will determine the metacentric height of a body (a measure of stability of a floating object) made up of a series of basic shapes. Results from the program will be tested against experimental results obtained by testing sample shapes in a water tank.

2. Relevant equations
So here is the thing. When I try to look up for journals on metacentric height, I don't find anything that is closely related to my topic or is of much help. Any of you know of any journals, books or articles that would be helpful for me? If you could suggest me some books/journals it would be very helpful !

3. The attempt at a solution

I have found these two articles on google that describes a metacentric height lab experiment. However I could not find the source and need a relevant source to actually carry out the experiment. Also the experiment described is a little confusing and I did not completely understand it. If anyone is familiar with a metacentric height experiment then please explain it to me

What you need to do is search for texts on naval architecture and ship stability.

Some of the basic texts are:

"Principles of Naval Architecture", Vol. 1, the Society of Naval Architects & Marine Engineers.
"Ship Hydrostatics and Stability", Adrian Biran
"Basic Ship Theory", AJ Rawson and EC Tupper

If you search the internet diligently, you may even find copies of these works available.

One document which is freely available on the internet is the Salvage Engineers Handbook:

http://wetlands.simplyaquatics.com/d/14936-1/sehv1.pdf [Broken]

The opening chapters give a basic review of ship stability calculations for salvage engineers.

Each of these three references will show how you calculate the basic hydrostatics of floating bodies and determine properties like the location of the metacenter. It sounds like the basic goal of your thesis project is to write a program to calculate the hydrostatic properties of floating objects.

Good Luck!
