stations in 31 provinces of Iran. The evapotranspiration was estimated using 11 temperature-based models and was compared with … evapotranspiration better than other models in the most provinces of Iran (25 provinces). However, the values of R<Superscript>2 …</Superscript> were less than 0.98 for 15 provinces of Iran. Therefore, the models were calibrated and preciseness of estimation was …

Relying on a linear causal thinking, most of the hydrological models fail to incorporate socio-economic characteristics of a watershed with hydrological and environmental attributes. Based on a systems thinking philosophy, the paper aims to adopt an Object-Oriented (OO) approach based on the...
