Impact of model structure and parameterization on Penman–Monteith type evaporation models
The impact ofmodel structure andparameterization on the estimation of evaporation is investigated across a range of Penman–Monteith type models. To examine the role of model structure on flux retrievals, three different retrieval schemes are compared. The schemes include a traditional single-source Penman– Monteith model (Monteith, 1965), a two-layer model based on Shuttleworth and Wallace (198...
متن کاملEstimation of the diurnal variation of potential evaporation from a wet bare soil surface
Parlange, M.B. and Katul, G.G., 1992. Estimation of the diurnal variation of potential evaporation from a wet bare soil surface. J. Hydrol., 132: 71-89. Potential evaporation from a wet bare soil field was measured with a large sensitive weighing lysimeter on a 20 min time step for 5 days at Davis, California. The diurnal evaporation rate modeled with the Penman-Brutsaert model for potential ev...
متن کاملEvaporation in a Mediterranean environment by energy budget and Penman methods, Lake Baratz, Sardinia, Italy
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,...
متن کاملCombining the Penman-Monteith equation with measurements of surface temperature and reflectance to estimate evaporation rates of semiarid grassland
The Penman-Monteith equation is useful for computing evaporation rates of uniform surfaces, such as dense vegetation or bare soil. This equation becomes less useful for evaluation of evaporation rates at the regional scale, where surfaces are generally characterized by a patchy combination of vegetation and soil. This is particularly true in the arid and semi-arid regions of the world. The appr...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
