  2. Water pricing - Wikipedia

    en.wikipedia.org/wiki/Water_pricing

    Key to effective and efficient water pricing is a systematic process to understand: (i) the value of water in alternative uses; (ii) the private and external costs of supplying water services; and (iii) the multiple options to determine an appropriate water tariff. Within the four dimensions of water pricing (uniform versus variable tariff and ...

  3. Canal lining - Wikipedia

    en.wikipedia.org/wiki/Canal_lining

    Canal lining is the process of reducing seepage loss of irrigation water by adding an impermeable layer to the edges of the trench. Seepage can result in losses of 30 to 50 percent of irrigation water from canals, so adding lining can make irrigation systems more efficient. Canal linings are also used to prevent weed growth, which can spread ...

  4. Coastal management - Wikipedia

    en.wikipedia.org/wiki/Coastal_management

    Coastal management is defence against flooding and erosion, and techniques that stop erosion to claim lands. [1] Protection against rising sea levels in the 21st century is crucial, as sea level rise accelerates due to climate change. Changes in sea level damage beaches and coastal systems are expected to rise at an increasing rate, causing ...

  5. Water supply network - Wikipedia

    en.wikipedia.org/wiki/Water_supply_network

    e. A water supply network or water supply system is a system of engineered hydrologic and hydraulic components that provide water supply. A water supply system typically includes the following: A drainage basin (see water purification – sources of drinking water) A raw water collection point (above or below ground) where the water accumulates ...

  6. Marginal cost - Wikipedia

    en.wikipedia.org/wiki/Marginal_cost

    In economics, the marginal cost is the change in the total cost that arises when the quantity produced is increased, i.e. the cost of producing additional quantity. [1] In some contexts, it refers to an increment of one unit of output, and in others it refers to the rate of change of total cost as output is increased by an infinitesimal amount ...

  7. Impact fee - Wikipedia

    en.wikipedia.org/wiki/Impact_fee

    t. e. An impact fee is a fee that is imposed by a local government within the United States on a new or proposed development project to pay for all or a portion of the costs of providing public services to the new development. [1] Impact fees are considered to be a charge on new development to help fund and pay for the construction or needed ...

  8. Landfill liner - Wikipedia

    en.wikipedia.org/wiki/Landfill_liner

    A landfill liner, or composite liner, is intended to be a low permeable barrier, which is laid down under engineered landfill sites. Until it deteriorates, the liner retards migration of leachate , and its toxic constituents, into underlying aquifers or nearby rivers from causing potentially irreversible contamination of the local waterway and ...

  9. Cost curve - Wikipedia

    en.wikipedia.org/wiki/Cost_curve

    In economics, a cost curve is a graph of the costs of production as a function of total quantity produced. In a free market economy, productively efficient firms optimize their production process by minimizing cost consistent with each possible level of production, and the result is a cost curve. Profit-maximizing firms use cost curves to ...
