A hydrologic model is a simplification of a real-world system (e.g., surface water, soil water, wetland, groundwater, estuary) that aids in understanding, predicting, and managing water resources.
SWAT is a continuous time model that operates on a daily time step at basin scale. The objective of such a model is to predict the long-term impacts in large basins of management and also timing of agricultural practices within a year (i.e., crop rotations, planting and harvest dates, irrigation, fertilizer, and pesticide application rates and timing).
Headwaters of the Pungwe River; HBV has been used to model this drainage basin. The HBV hydrology model, or Hydrologiska Byråns Vattenbalansavdelning model, is a computer simulation used to analyze river discharge and water pollution.
The Salto Santiago Hydroelectric Power Plant is a dam and hydroelectric power plant on the Iguazu River near Santiago in Paraná, Brazil.It is the third dam upstream of the Iguazu Falls and was completed in 1979.
Oxygen-18 (18 O, Ω [1]) is a natural, stable isotope of oxygen and one of the environmental isotopes.. 18 O is an important precursor for the production of fluorodeoxyglucose (FDG) used in positron emission tomography (PET).
The Río Salado, also Río Salado de los Nadadores, [1] or Salado River, is a river in northern Mexico, a tributary of the Rio Grande (Río Bravo).Its basin extends across the northern portion of Coahuila, Nuevo Leon, and Tamaulipas states.
Water Resources Management (WRM) in Chile is widely known for its 1981 Water Code—written after General Augusto Pinochet took control through a military coup d'état. Free-market mechanisms became the economic philosophy in WRM, including the development of water markets and tradable water permits. [1]
