In Mexico, large dams have been a critical component of the water supply. However, places where they can be built are scarcer every day, situation that adds to high costs and social conflicts cause. Much stored in is lost due evaporation, so technological alternatives currently being investigated reduce it. Regarding determination evaporated volumes, data obtained with evaporimeters do not repr...

     Rainfall runoff modeling and prediction of river discharge is one of the important practices in flood control and management, hydraulic structure design and drought management. The present article aims to simulate daily streamflow in Kasilian watershed using an artificial neural network (ANN) and neuro-fuzzy inference system (ANFIS). The intelligent methods have the high potential for dete...

Abstract The results reveal statistically significant trends with distinct slopes in quantiles for each station and season so that the changes trend of high values (quantile 0.9) evaporation were more than low 0.1). In spring, medium rates increased northern regions province (the highest slope, 0.15 mm/decade northeast), while they fell (with a slope −0.15 mm/decade) southern regions. But summe...

This report investigates the influence of surface chemistry (or wettability) on the evaporation performance of free-standing double-layered thin film on the surface of water. Such newly developed evaporation system is composed of top plasmonic light-to-heat conversion layer and bottom porous supporting layer. Under solar light illumination, the induced plasmonic heat will be localized within th...

Evaporation from soil columns in the presence of a water table is a long lasting subject that has received great attention for many decades. Available analytical studies on the subject often involve an assumption that the potential evaporation rate is much less than the saturated hydraulic conductivity of the soil. In this study, we develop a new semi-analytical method to estimate the evaporati...

shallot (allium altissimum regel.) is a medicinal, industrial and perennial plant that has underground tubers. it is one of the most important allium species in iran, which normally grows in semi-cold to very cold highlands. because of being a wild plant, shallot is encounter with water deficit during its growth season. therefore evaluation of water requirement of shallot is important. in order...

Using empirical models for estimating evaporation requires a lot of variables that some of them can not be measured in the stations. Therefore, this study aimed to simulate the daily evaporation of Tabriz synoptic satation using meteorological data including average temperature of air (ْc), wind velocity mean (m/s), relative humidity (%) and sun light hours by Adaptive Neuro-Fuzzy Inference Syst...

The purpose of this paper is to estimate the evaporation rate in the purification of wastewater by aquatic plants with aeration. Evaporation of surface water is important in dewatering processes. In particular, this is true in arid climates, where evaporation rates are high. Aeration is known to enhance the wastewater purification process, but it increases concurrently the water evaporation rat...
