Catchment Hydrology

  • Another application involves the separation of groundwater flow and baseflow from streamflow in the field of catchment hydrology (i.e. a method of hydrograph separation). (
  • Isotope Tracers in Catchment Hydrology. (
  • Catchment hydrology, is the study of the hydrology in drainage basins. (
  • Catchment hydrology is based on the principal of continuity, which is used to perform a water balance on a catchment: I − O = d S / d t {\displaystyle I-O=dS/dt} , where I {\displaystyle I} = inputs (P, precipitation + OW, occult water), O {\displaystyle O} = outputs (ET, evapotranspiration + R, runoff), and d S / d t {\displaystyle dS/dt} = the change in catchment storage over time. (
  • For more information see water balance) There are many terms involved with and related to catchment hydrology. (

Urban Hydrology

  • Urban Hydrology deals with the specific aspects of the hydrological cycle in urban and industrial settings. (

Isotope Hydrology

  • Isotope hydrology is the study of the isotopic signatures of water. (
  • Isotope hydrology is a field of hydrology that uses isotopic dating to estimate the age and origins of water and of movement within the hydrologic cycle. (
  • Carbon 14 dating is also used as part of isotope hydrology as all natural water contains dissolved carbon dioxide. (
  • Stable isotopes in the water molecule are also useful in tracing the sources (or proportion of sources) of water that plants use The isotope hydrology program at the International Atomic Energy Agency works to aid developing states (including 84 projects in more than 50 countries) and to create a detailed portrait of Earth's water resources. (


  • Domains of hydrology include hydrometeorology, surface hydrology, hydrogeology, drainage-basin management and water quality, where water plays the central role. (

South Africa

  • The purpose of the study was to evaluate and compare the methods used in flood hydrology to estimate depth-duration-frequency (DDF) relationships of design rainfall in South Africa based on the critical storm duration or time of concentration ( T C ) of a catchment. (

  • Socio-hydrology is an interdisciplinary field studying the dynamic interactions and feedbacks between water and people. (


  • Surface hydrology is the study of hydrologic processes that operate at or near Earth's surface. (
  • If the arrival of the water at the soil surface is less than the infiltration capacity, it is sometimes analyzed using hydrology transport models, mathematical models that consider infiltration, runoff and channel flow to predict river flow rates and stream water quality. (
  • In hydrology and geography, armor is the association of surface pebbles, rocks or boulders with stream beds or beaches. (
  • In surface water hydrology and civil engineering, drawdown refers to the lowering of the water level in a man-made reservoir or tank. (
