“…Despite many energy budget studies, comparisons between BREB and Penman's methods are few (e.g. Winter et al, 1995;Yin and Nicholson, 1998;Vallet-Coulomb et al, 2001;Shanahan et al, 2007;Rosenberry et al, 2007). In those papers, the two methods yield a difference ranging between 5 and 20 %.…”

Abstract. In Mediterranean environments, evaporation is a key component of lake water budgets. This applies to Lake Baratz in Sardinia, Italy, a closed lake that almost dried up in 2008 after a succession of years with low seasonal rainfall. We used the energy budget method and Penman's equation to estimate evaporation over Lake Baratz. We measured, using a raft station, water temperature at the surface, at 1, 2, 4, 6 m depth and at the bottom of the lake, as well as air temperature, relative humidity, wind speed, and net radiation over a period of 3 years. We also compared Penman's equation and the energy budget method in two other climatic zones using published data. Our results indicate that mean yearly evaporation over Lake Baratz was 950 mm. On an annual scale, evaporation estimated by Penman's method omitting heat storage as is usually done was 18 % higher than by the energy budget method that included heat storage, with monthly differences ranging between −38 and +60 %. Including the heat storage term in Penman's equation changed the monthly values but did not change the yearly value significantly. Solar radiation and heat storage were found to be the most important energy fluxes to and from the lake and had the greatest effect on evaporation rates for the energy budget method. The bias between the two methods has a seasonal cycle due to the storage and release of energy from the lake. Energy advected to and from the lake by precipitation, surface water and ground water had minor effect on evaporation rates. Lake Baratz, like other lakes in a Mediterranean environment, is particularly sensitive to the summer hot and dry climate. In contrast, we found that rates of evaporation estimated from Penman and the energy budget methods over tropical African lakes were nearly constant over the entire year and the difference between the two methods smaller. Difference between the two methods for North American lakes is also smaller probably owing to the ice-cover season and to lower radiation and lower temperatures during summer.

“…The performance rank of the six methods recommended by Winter et al [35], Rosenberry et al [21] and YAO [37] are also listed in Table 5. It would be understandable that the all ranks may be different because the lakes are in different locations, and the datasets used are different YAO [37].…”

Abstract:Variations in lake evaporation have a significant impact on the energy budget and water budget of lake.Understanding these variations and the role of climate is important for water resource management as well as predicting future changes in Lake Hydrology as a result of climate change. This study presents a comprehensive of 10 years dataset (2003 -2012) from Lake Brullus (Nile Delta Lake) North-Egypt for monthly and annually variations in lake evaporation. Evaporation during this interval was calculated using six evaporation methods, based on field meteorology, and lake water temperature data. Actual evaporation determined during a month of a year was estimated using a lake energy budget model, and the estimation was used as reference evaporation for evaluation of the six methods. The deviations of method carried out evaporation results from the reference evaporation were compared among the six methods, and an execution rank was suggested based on the root mean squared deviation and coefficient of efficiency. Makkink method was the best method for the whole data interval, followed by DeBruin-Kejiman method and the poor one is Penman method.

RESUMO:A disponibilidade hídrica em açudes e reservatórios de diferentes regiões do mundo tem sofrido significativa redução em função da ausência de chuvas, poluição da água, crescente consumo no campo e nas cidades e elevadas perdas por evaporação. Dessa forma, o trabalho teve como objetivo determinar a evaporação da água com baixa turbidez armazenada em reservatórios revestidos com manta impermeável destinada à irrigação da cultura do fumo para exportação. A pesquisa foi conduzida em dois reservatórios de uma Fazenda propriedade da empresa DANCO, localizada no município de Governador Mangabeira (12º37' S; 39º03' W; 218 m). Para determinação da evaporação da água por meio do método do balanço de energia com Razão de Bowen, foram utilizadas três estruturas equipadas com instrumentos para coleta dos dados; sendo duas plataformas flutuantes e uma torre meteorológica. Observa-se que na média para todo o período de 74 dias de estudo (18 de setembro a 30 de novembro de 2016), a soma dos fluxos turbulentos (calor sensível + calor latente) correspondeu a 90,3% da energia disponível (radiação líquida -calor na água). A lâmina média de evaporação encontrada foi de 4,7 mm dia -1 , variando de 0,61 a 8,0 mm, com total acumulado de 350 mm. PALAVRAS-CHAVE: calor latente, razão de Bowen, micrometeorologia ENERGY BALANCE AND EVAPORATION OF LOW TURBIDITY WATER IN AGRICULTURAL USE RESERVOIRSABSTRACT: Water availability in dams and reservoirs in different regions of the world has suffered a significant reduction due to the absence of rainfall, water pollution, increasing consumption in the countryside and cities and high losses due to evaporation. Thus, the objective of this research was to quantify the evaporation of water with low turbidity stored in reservoirs coated with Impermeable blanket and destined to the irrigation of the culture of the 1 Doutoranda em Engenharia Agrícola, UFRB, Cruz das Almas -Bahia.
