  2. 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 ...

  3. Stock-flow consistent model - Wikipedia

    en.wikipedia.org/wiki/Stock-Flow_consistent_model

    Once the accounting framework is fulfilled then the structure of the model, based on stylized facts, is defined. The set of equations in the model defines relationship between different variables, not determined by the accounting framework. The model structure basically helps in understanding how the flows are connected from a behavioral ...

  4. Streamflow - Wikipedia

    en.wikipedia.org/wiki/Streamflow

    A hydrograph is a chart showing, most often, river stage (height of the water above an arbitrary altitude) and streamflow (amount of water, usually in cubic feet per second). Other properties, such as rainfall and water quality parameters can also be plotted.

  5. Discharge (hydrology) - Wikipedia

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

    A hydrograph is a graph showing the rate of flow (discharge) versus time past a specific point in a river, channel, or conduit carrying flow. The rate of flow is typically expressed in units of cubic meters per second (m³/s) or cubic feet per second (cfs). Hydrographs often relate changes of precipitation to changes in discharge over time.

  6. Chart of accounts - Wikipedia

    en.wikipedia.org/wiki/Chart_of_accounts

    A chart of accounts (COA) is a list of financial accounts and reference numbers, grouped into categories, such as assets, liabilities, equity, revenue and expenses, and used for recording transactions in the organization's general ledger.

  7. Hydrographic survey - Wikipedia

    en.wikipedia.org/wiki/Hydrographic_survey

    The General Bathymetric Chart of the Oceans (GEBCO) is a publicly available bathymetric chart of the world's oceans. The project was conceived with the aim of preparing a global series of charts showing the general shape of the seafloor. Over the years it has become a reference map of the bathymetry of the world's oceans for scientists and others.

  8. List of unsolved problems in economics - Wikipedia

    en.wikipedia.org/wiki/List_of_unsolved_problems...

    Transformation problem: The transformation problem is the problem specific to Marxist economics, and not to economics in general, of finding a general rule by which to transform the values of commodities based on socially necessary labour time into the competitive prices of the marketplace. The essential difficulty is how to reconcile profit in ...

  9. Stock and flow - Wikipedia

    en.wikipedia.org/wiki/Stock_and_flow

    Economics, business, accounting, and related fields often distinguish between quantities that are stocks and those that are flows. These differ in their units of measurement . A stock is measured at one specific time, and represents a quantity existing at that point in time (say, December 31, 2004), which may have accumulated in the past.
