  2. List of rivers by discharge - Wikipedia

    en.wikipedia.org/wiki/List_of_rivers_by_discharge

    For context, the volume of an Olympic-size swimming pool is 2,500 m 3 (88,000 cu ft). The average flow rate at the mouth of the Amazon is sufficient to fill more than 83 such pools each second. The estimated global total for all rivers is 1.2 × 10 6 m 3 /s (43 million cu ft/s), [1] of which the Amazon would be approximately 18%.

    US hydropower generated 1949-2008 (blue), and hydropower as percent of total US electricity (red). Hydroelectric power generation in the United States. The earliest hydroelectric power generation in the U.S. was utilized for lighting and employed the better understood direct current (DC) system to provide the electrical flow.

  5. Hydropower - Wikipedia

    en.wikipedia.org/wiki/Hydropower

    A hydropower resource can be evaluated by its available power. Power is a function of the hydraulic head and volumetric flow rate. The head is the energy per unit weight (or unit mass) of water. [5] The static head is proportional to the difference in height through which the water falls. Dynamic head is related to the velocity of moving water.

  6. List of waterfalls by flow rate - Wikipedia

    en.wikipedia.org/.../List_of_waterfalls_by_flow_rate

    This list of waterfalls by flow rate includes all waterfalls which are known to have an average flow rate or discharge of at least 150 cubic metres per second (5,300 cu ft/s). The waterfalls in this list are those for which there is verifiable information, and the list should not be assumed to be a complete list of waterfalls which would ...

    en.wikipedia.org/wiki/Run-of-the-river...

    The European Network of Transmission System Operators for Electricity distinguishes run-of-the-river and pondage hydropower plants, which can hold enough water to allow generation for up to 24 hours (reservoir capacity / generating capacity ≤ 24 hours), from reservoir hydropower plants, which hold far more than 24 hours of generation without ...
