Course Information

About this Course

The course introduces hydrological cycle and concept of water budget. Precipitation, evaporation and infiltration processes are discussed that include measurements and analysis. Stream flow measurements, stage-discharge, rainfall-runoff relationships and hydrograph analysis are explained. Rational method, flood routing and the use of probability and statistical method in hydrologic analysis are presented. Applications of hydrology principles in urban stormwater design using procedures outlined in Manual Saliran Mesra Alam Malaysia (MSMA) are discussed. The course concludes with an introduction to hydrologic modeling and simulation.

Frequently Asked Questions

Q1 : What is the different between hydrology and hydraulic
A1 : Hydrology is about the water itself where it comes from where it goes However hydraulic is the structure to convey and store water
