Hydraulic engineering is just a part of civil engineering. It is based on flow and conveyance of fluids, mainly water and sewage. It can be seen as an application of fluid mechanics for taking care of problems arising during storage, transport, regulation, measurement and use of water. This is needed while designing dams, canals, or cooling water facilities for thermal power plants.

Fossils (from the Latin fossilis, which means 'excavated') are the remains or signs of the activity of past organisms.These remains, preserved in sedimentary rocks, may have undergone changes in their composition (by diagenesis) or deformations (by dynamic metamorphism) more or less intense.
