  2. Hydrograph - Wikipedia

    en.wikipedia.org/wiki/Hydrograph

    A unit hydrograph (UH) is the hypothetical unit response of a watershed (in terms of runoff volume and timing) to a unit input of rainfall. It can be defined as the direct runoff hydrograph (DRH) resulting from one unit (e.g., one cm or one inch) of effective rainfall occurring uniformly over that watershed at a uniform rate over a unit period ...

  3. Hydrological transport model - Wikipedia

    en.wikipedia.org/wiki/Hydrological_transport_model

    Building on the work of Horton, the unit hydrograph theory was developed by Dooge in 1959. [18] It required the presence of the National Environmental Policy Act and kindred other national legislation to provide the impetus to integrate water chemistry to hydrology model protocols.

  4. Runoff model (reservoir) - Wikipedia

    en.wikipedia.org/wiki/Runoff_model_(reservoir)

    Computing the total hydrograph Provided the value of A is known, the total hydrograph can be obtained using a successive number of time steps and computing, with the runoff equation, the runoff at the end of each time step from the runoff at the end of the previous time step. Unit hydrograph The discharge may also be expressed as: Q = − dS/dT .

    The SWMM 5.0.001 to 5.1.022 main components are rain gages, watersheds, LID controls or BMP features such as Wet and Dry Ponds, nodes, links, pollutants, landuses, time patterns, curves, time series, controls, transects, aquifers, unit hydrographs, snowmelt and shapes (Table 3). Other related objects are the types of Nodes and the Link Shapes.

  6. Hydrological model - Wikipedia

    en.wikipedia.org/wiki/Hydrological_model

    The model may be created in one (core, column), two (plan, profile), or three dimensions, and can be designed to represent a variety of specific initial and boundary conditions as needed to answer a question. Scale models commonly use physical properties that are similar to their natural counterparts (e.g., gravity, temperature).

  7. Discharge (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Discharge_(hydrology)

    Analysis of the relationship between precipitation intensity and duration and the response of the stream discharge are aided by the concept of the unit hydrograph, which represents the response of stream discharge over time to the application of a hypothetical "unit" amount and duration of rainfall (e.g., half an inch over one hour). The amount ...
