CHAPTER 1: INTRODUCTION TO HYDROLOGY AND HYDRAULICS


HYDROLOGY

  • Hydrology is the study or science of transforming rainfall amount into the quantity of runoff. 
  • Hydrology is "The science which treats of water, its properties and laws, its distribution over the earth's surface, etc."
  • Hydrology is generally related to the study of rainfall and to water in connection to geography and geology.



HYDRAULICS

  • Hydraulics is the study or science of taking that quantity of runoff to determine a flood level.
  • Hydraulics is “That department of science which deals with the conveyance of water or other liquids through pipes or other artificial channels, and with the various mechanical applications of the force exerted by moving liquids. Often used in a wider sense, corresponding to what is now expressed by hydrokinetics or hydrodynamics. “(From the OED).
  • Hydraulics is more geared towards physics, the study of the motion of liquids in relation to disciplines such as fluid mechanics and fluids dynamics, etc.




DIFFERENTIATE BETWEEN HYDRAULICS AND HYDROLOGY




HYDRAULICS
HYDROLOGY
  1. Technology and applied science using engineering, chemistry and other science involving the mechanical properties and use liquid or fluids.
1.1. Scientific study of the experiment of the movement, distribution and quality of water on earth.
  1. Hydraulics is more geared towards physics, the study of the motion of liquids in relation to disciplines such as fluid mechanics and fluids dynamics
1.2.Hydrology is generally related to the  study of rainfall and to water in connection to geography and geology.

  1. Man made
    1.3. Nature
