  2. 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).

  3. Flood management - Wikipedia

    en.wikipedia.org/wiki/Flood_management

    A weir was built on the Humber River (Ontario) to prevent a recurrence of a catastrophic flood. Flood management describes methods used to reduce or prevent the detrimental effects of flood waters. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff.

  4. Floodplain - Wikipedia

    This can encourage farming; [4] some important agricultural regions, such as the Nile and Mississippi river basins, heavily exploit floodplains. Agricultural and urban regions have developed near or on floodplains to take advantage of the rich soil and freshwater. However, the risk of inundation has led to increasing efforts to control flooding.

    The hundreds of tube wells installed in Uttar Pradesh, India, with World Bank funding, have operating periods of 1.4 to 4.7 hours/day. In contrast, they were designed to operate 16 hours/day [ 20 ] In Baluchistan , Pakistan , the development of tube well irrigation projects was at the expense of the traditional qanat or karez users [ 15 ]

  6. Recessional agriculture - Wikipedia

    en.wikipedia.org/wiki/Recessional_agriculture

    Recessional agriculture, also known as flood retreat agriculture, is a form of agricultural cultivation that takes place on a floodplain. Farmers practice recessional agriculture by successively planting in the flooded areas after the waters recede. [1] Seeds are scattered on the fertile silt deposited by the receding flood.

    On the other hand, a little over 50% of all pork production and 70% of all poultry production worldwide originated from animals kept entirely in confined buildings even around 2006, and the raw numbers were expected to increase by 3–3.5 times for pigs, by 2–2.4 times for layer hens and 4.4–5 times for broilers.

    The center is located in the University of Ghana and it is involved in conducting various research works and projects with regards to climate change in Ghana. It is also a multidisciplinary faculty which explores areas such as health, resource management, economics and renewable energy.

  9. Entrainment (hydrodynamics) - Wikipedia

    en.wikipedia.org/wiki/Entrainment_(hydrodynamics)

    Eductors or eductor-jet pumps make use of entrainment. They are used on board ships to pump out flooded compartments: seawater is pumped to the eductor and forced through a jet, and any fluid at the inlet of the eductor is carried along to the outlet, and then up and out of the compartment.
