Summary - Physical Hydrology Third Edition

  • 1.1 Definition and Scope of Hydrology

  • What are the principal focuses of hydrology?
    1. The way a water substance is distributed and moved on and under the earth's land surfaces and its exchange with the atmosphere.
    2. The physical and chemical interaction with earth materials.
    3. The biological processes and human activities affecting the movement, distribution and quality of water.
  • What are the three principal focuses of hydrology?
    1. The way a water substance is distributed and moved on and under the earth's land surfaces and its exchange with the atmosphere.
    2. The physical and chemical interaction with earth materials.
    3. The biological processes and human activities affecting the movement, distribution and quality of water.
  • The global hydrologic cycle includes the variations of water substance through time and space in the ocean, atmosphere and on the terrestrial compartments of the global water system.
  • The hydrologic cycle plays a central role in the earth's climate system from local to global scale.
  • What is Hydrology?
    Hydrology is the quantitive geophysical science that describes and predicts fresh water occurrence and circulation
  • What are the three principle focuses of Hydrology?
    1. The distribution and movement of water on and under the surface and exchanges with the atmosphere
    2. Its physical and chemical interaction with earth materials.
    3. The biological processes and human activities affecting the movement, distribution and quality of water.
  • 1.2 Approach and Scope of This Book

  • Basic science and mathematics is treated by fosusing on (1) relatively simple but conceptually sound quantitative representations of physical hydrologic processes and (2) approaches to the measurement of the quantities and flow rates of water and energy involved in those processes
  • 1.3 Physical Quantities and Laws

  • On which basic laws of classical physics are hydrologic relationships most often based?
    1. Conservation of mass
    2. Newton's laws of motion
    3. Conservation of energy
    4. (Fick's first law of difussion)
  • 1.4.1 Dimensions

  • What does the Law of conversation of Mass say?
    Mass is neither created nor destroyed
  • What 3 points are stated in Newtons Law of Motion?
    1. Conservation of momentum (body stays still unless external force acts on it)
    2. Change of momentum is at same rate as force acting on body, in same direction. Force=Mass*Acceleration
    3. There is always a corresponding force in the other direction with the same magnitude
  • What do the 2 laws of thermodynamics say?
    1. Energy is neither created or destroyed 
    2. heat energy always moves from the warmer to the cooler body
  • Dimension involving length are classed as geometric, those involving length and time or time only are kinematic, mass or force as dynamic and those involving temperature are thermal.
  • What does Fick´s Law say?
    Fick´s Law of diffusion says that a diffusing substance always moves from high to low concentration
  • 1.4.3 Dimensional Properties of Equations

  • What are the two most important rules in terms of equations?
    1. A dimensionally homogeneous equation that completely and correctly describes a physical relation has the same dimensions on both sides of the equal sign.
    2. In equations, the dimensions and units of quantities are subject to the same mathematical operations as the numerical magnitudes.
  • Hydrologists are often forced to develop and rely on relatively simple empirircal equations which may be dimensionally inhomogeneous. What are empirical equations and how are they developed? 
    Equations based on observed relations between measured quantities which are developed via the statistical process of regression analysis.
  • Equations can be dimensionally homogeneous but not unitarily homogeneous. However, all unitarily homogeneous equations are dimensionally homogeneous.

What is a watershed, drainage basin, river basin or catchment?
The area that drains water into a single river
What is the latent heat of fusion and the latent heat of vaporization?
Latent heat of fusion is the quantity that describes the amount of energy added or released during melting or freezing (water: 3.34 KJ/kg). Latent heat of vaporization is the same, but accounts for vaporization and condensation (water at 10 C: 2.471 MJ/kg decreasing with rising T).
What does Fick´s Law say?
Fick´s Law of diffusion says that a diffusing substance always moves from high to low concentration
What do the 2 laws of thermodynamics say?
  1. Energy is neither created or destroyed 
  2. heat energy always moves from the warmer to the cooler body
