Kuraklık, çeşitli sosyal ve çevresel etkileri olan en önemli doğal afetlerden biridir. Bu nedenle, kuraklığı izlemek için özellikle uygun bir indeks seçmek çok önemlidir. Standartlaştırılmış Yağış İndisi (SPI) Evapotranspirasyon (SPEI) kuraklık izlemede yaygın olarak kullanılmaktadır. çalışmada, yarı kurak özelliklere sahip Kırıkkale ilinde kuraklığın gelişimini özelliklerini incelemek amacıyla...

So far, various methods have been presented for determining reference crop evapotranspiration in different parts of the world. The most popular and prestigious of them are probably the combined methods of Penman family, modified Blany-Criddle, Hargreaves - Samani and thornthwaite. Due to lack of lysimeter data in many parts of Iran, presenting an equation according to the regional condition wit...

The evapotranspiration rate has a vital role in agricultural water management. In this paper, ability of Box-Jenkins models in forecasting the reference potential evapotranspiration is estimated. For this purpose meteorological data of Mehrabad synoptic station in Tehran was selected. Using this data and according to eight famous evapotranspiration equations amounts of evapotranspiration were f...

Potential evapotranspiration (PET) indicates if a cultivation area is suitable for planting. Currently, site-specific PET models that are based on large geographic regions vulnerable to inaccurate predictions as result of climate change and sudden changes in the environmental abiotic stressors affect plant growth. For aim promoting papaya Sinta F1 cultivar, study optimized standard Thornthwaite...

Evapotranspiration is an important parameter to evaluate soil water deficit and use efficiency, especially in locations with irregularly distributed precipitation. The aim of this study was assess the daily actual evapotranspiration (ETa) estimated by Thornthwaite Mather balance adapted for crops (ThM) dual Kc method crop coefficients optimized from inverse modeling adjustment suggested FAO-56 ...

The water balance of a watershed is critical for the estimation budget to meet present and future domestic economic demand supply water. Water parameters like precipitation, temperature, evapotranspiration soil moisture content deficit surplus determine which further influenced by factors land use, types, seasonal variation other environmental factors. This paper intends estimate Barsachhu usin...

O balanço hídrico climatológico (BHC) é uma das formas de monitorar o armazenamento água no solo, sendo ferramenta essencial planejamento estratégico agrícola. Deste modo, conhecer a época maior disponibilidade e déficit torna-se importante para auxiliar na tomada decisão sobre agrícola em um determinado local. Contribui que fase planejamento, novas barragens sejam construídas água; os sistemas...

Seeking to contribute with the management of water resources in Itaipu Binacional reservoir region, this research aimed characterize dynamics evapotranspiration and evaluate performance different mathematical methods, which determine reference (ETo) from air temperature values. Fifteen municipalities were analyzed. After obtaining data series, ETo was estimated using six methods: Camargo (C), H...
