Engineering Hydrology

This course on engineering hydrology aims to impart knowledge on the processes that secure the most valuable natural resource: WATER. It deals with the complex interaction and pathways of water connecting atmosphere, lithosphere and hydrosphere. This course will give an idea on how the hydrological science is mathematically quantified for engineering applications to manage water resources. The knowledge acquired in this course will be pre-requisite for different advanced level courses in post-graduate. The course starts with the explanation of hydrological processes related to atmosphere, surface and subsurface regime. This is followed by the explanation on hydrological analysis, which is mandatory for the design of hydraulic structures. The course ends with basic discussion on hydrological statistics important for dealing significant amount of data and its uncertainties, which forms the backbone of hydrological analysis.INTENDED AUDIENCE : Undergraduate students in Civil EngineeringPREREQUISITES :NilINDUSTRY SUPPORT :Basic civil engineering infrastructural companies.
