Two Comprehensive and Practical Methods for Simulating Pan Evaporation Under Different Climatic Conditions in Iran

open access: yesWater, 2021
Evaporation from surface water plays a key role in water accounting of basins, water resources management, and irrigation systems management, so simulating evaporation with high accuracy is very important.

Modeling monthly pan evaporation process over the Indian central Himalayas: application of multiple learning artificial intelligence model

open access: yesEngineering Applications of Computational Fluid Mechanics, 2020
The potential of several predictive models including multiple model-artificial neural network (MM-ANN), multivariate adaptive regression spline (MARS), support vector machine (SVM), multi-gene genetic programming (MGGP), and ‘M5Tree’ were assessed to ...

Simulation of Pan-Evaporation Using Penman and Hamon Equations and Artificial Intelligence Techniques

open access: yes, 2021
The evaporation losses are very high in warm-arid regions and their accurate evaluation is vital for the sustainable management of water resources. The assessment of such losses involves extremely difficult and original tasks because of the scarcity of ...

Evaluation of CatBoost Method for Predicting Weekly Pan Evaporation in Subtropical and Sub-Humid Regions

open access: yesPure and Applied Geophysics
Pan evaporation modeling and forecasting are needed to provide timely, continuous, and valuable information to support water management. This study aimed to overcome the constraints identified in traditional regression techniques and less explored ...

Urbanization Significantly Affects Pan-Evaporation Trends in Large River Basins of China Mainland

open access: yesLand, 2021
The causes of the pan-evaporation decline have been debated, and few researches have been carried out on the possible effect of local land use and land cover change on the regional pan-observation data series.

Laboratory Comparison of Evaporation Rate Between Colorado Sanken Evaporation Pan and Class A Evaporation Pan (Case Study: Semnan, Iran)

open access: yes, 2023
One method of estimating the evaporation rate (ER) is to use a variety of evaporation pans, such as the Class A standard evaporation pan (CASEP) and the Colorado Sanken standard evaporation pan (CSSEP). In this study, the rate of evaporation of CASEP and CSSEP have been investigated and compared with each other. This study was conducted in Semnan, Iran.

The aerodynamics of pan evaporation

open access: yesAgricultural and Forest Meteorology, 2012
Abstract In response to worldwide observations reporting a decline in pan evaporation over the last 30–50 years, we developed an instrumented US Class A pan that replicated an operational pan at Canberra Airport in Australia. The aim of the experimental facility was to investigate the physics of pan evaporation under non-steady state conditions.

Diverse trends in observed pan evaporation in South Africa suggest multiple interacting drivers

open access: yes, 2021
FUNDING: None Planning for future water resource management in a warming climate is confounded when an expectation of increasing evaporation from open water surfaces with global warming is contradicted by observations of secular declines of pan ...

Does evaporation paradox exist in China? [PDF]

open access: yes, 2009
One expected consequence of global warming is the increase in evaporation. However, lots of observations show that the rate of evaporation from open pans of water has been steadily decreasing all over the world in the past 50 years.
