    en.wikipedia.org/wiki/List_of_graphical_methods

    This is a list of graphical methods with a mathematical basis. Included are diagram techniques, chart techniques, plot techniques, and other forms of visualization . There is also a list of computer graphics and descriptive geometry topics .

  3. Origin (data analysis software) - Wikipedia

    en.wikipedia.org/wiki/Origin_(data_analysis...

    Origin Workbook with sparklines above data columns, this allows a quick glance of the data without plotting them. Origin is primarily a GUI software with a spreadsheet front end. Unlike popular spreadsheets like Excel, Origin's worksheet is column oriented. Each column has associated attributes like name, units and other user definable labels.

  4. Double mass analysis - Wikipedia

    en.wikipedia.org/wiki/Double_mass_analysis

    An example of a double mass analysis is a "double mass plot", or "double mass curve". [3] For this, points and/or a joining line are plotted where the x- and y- coordinates are determined by the running totals of the values observed at two stations.

  5. Hydrograph - Wikipedia

    en.wikipedia.org/wiki/Hydrograph

    A stream hydrograph is commonly determining the influence of different hydrologic processes on discharge from the subject catchment. Because the timing, magnitude, and duration of groundwater return flow differs so greatly from that of direct runoff, separating and understanding the influence of these distinct processes is key to analyzing and simulating the likely hydrologic effects of ...

  6. Flow visualization - Wikipedia

    en.wikipedia.org/wiki/Flow_visualization

    In scientific visualization flows are visualized with two main methods: Analytical methods that analyse a given flow and show properties like streamlines, streaklines, and pathlines. The flow can either be given in a finite representation or as a smooth function. Texture advection methods that "bend" textures (or images) according to the flow ...

  7. 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 .

  8. Hydrographic survey - Wikipedia

    en.wikipedia.org/wiki/Hydrographic_survey

    Images acquired under the initial attempts at MBES bottom imaging were less than stellar, but fortunately improvements were forthcoming. Side scan sonar parses the continual echo returns from a receive beam that is perfectly aligned with the insonification beam using time-after-transmit, a technique that is independent of water depth and the ...

  9. Streamflow - Wikipedia

    en.wikipedia.org/wiki/Streamflow

    Plotted on a graph, these data from the unit hydrograph for that storm, which represents the runoff added to the pre-storm baseflow. To forecast the flows in a large drainage basin using the unit hydrograph method would be difficult because in a large basin geographic conditions may vary significantly from one part of the basin to another. This ...
