The Penman equation describes evaporation (E) from an open water surface, and was developed by Howard Penman in 1948. Penman's equation requires daily mean temperature, wind speed, air pressure, and solar radiation to predict E. Simpler Hydrometeorological equations continue to be used where obtaining such data is impractical, to give comparable results within specific contexts, e.g. humid vs ...
Ch. 1, "Evaporation" Transpiration: the movement of water from root systems, through a plant, and exit into the air as water vapor. This exit occurs through stomata in the plant. Rate of transpiration can be influenced by factors including plant type, soil type, weather conditions and water content, and also cultivation practices. [6]: Ch. 1 ...
This garden pond has two ponds separated by a waterfall with a one-foot drop; generally, the fish in the upper pond are smaller, and ones in the lower pond are larger. Ponds may be created by natural processes or by people; however, the origin of the hole in the ground makes little difference to the kind of wildlife that will be found in the pond.
The Important Bird Area (IBA) comprises a system of evaporation ponds, the intake zone where seawater enters, and the adjacent intertidal mudflats. The system includes levee banks and scattered mangroves. During low tides, waterbirds forage on the mudflats and along nearby creeks. During high tides, they move to the saltworks to continue ...
Since evaporation ponds operate best with greater surface area of evaporation, large amount of land is required, so low quality, low cost land is better [2] A shallow pond covering greater surface area will result in faster rates of evaporation. [2] A view of evaporation ponds that are designed to extend for miles of land
E = Mass water evapotranspiration rate (g s −1 m −2) ET = Water volume evapotranspired (mm s −1 ) Δ = Rate of change of saturation specific humidity with air temperature.
The Hertz–Knudsen equation describes the non-dissociative adsorption of a gas molecule on a surface by expressing the variation of the number of molecules impacting on the surfaces per unit of time as a function of the pressure of the gas and other parameters which characterise both the gas phase molecule and the surface: [1] [2]
Inputs to SPEI datasets can include high-resolution potential evapotranspiration (PET) from the Global Land Evaporation Amsterdam Model (GLEAM) and hourly Potential Evapotranspiration (hPET). GLEAM is a set of algorithms designed to calculate actual evaporation, PET, evaporative stress, and root-zone soil moisture. [5]
