Prediction of potential evapotranspiration (PET) using an artificial neural network (ANN) with a different architecture is not uncommon. Most researchers select the optimal statistical indicators. However, there still gap to be filled in future applications various drought indices and assessment location, duration, average, maximum minimum. The objective was compare performance PET computed ANN...

abstract potential evapotranspiration is one of basic parameter in hydrologic cycle that should be estimate in irrigation design and scheduling, watershed hydrology studies. many applications in diverse disciplines require estimates of evapotranspiration (et) at hourly or smaller time steps. the primary objectives of this study were to compare the american society of civil engineers (asce) and ...

A simplified equation to estimate spatial reference evapotranspiration (ETo_Ts) from remote sensing-based surface temperature (Ts) and local standard meteorological data is suggested. It is based on a parameterization of the meteorological conditions of the first few meters of the atmosphere through two parameters (a and b) which come from a simpler form of the Penman–Monteith equation:

17 18 The responses of canopy conductance to variation in solar radiation, vapour pressure deficit and soil 19 moisture have been extensively modelled using a Jarvis-Stewart (JS) model. Modelled canopy 20 conductance has then often been used to predict transpiration using the Penman-Monteith (PM) 21 model. We previously suggested an alternative approach in which the JS model is modified to 22

Introduction: The Antiepileptic medications are frequently categorized into divisions such as ‘first-generation’ (i.e., carbamazepine, phenobarbital, phenytoin, primidone, and valproate) ‘second-generation’ (lamotrigine, levetiracetam, felbamate, gabapentin, topiramate, tiagabine, oxycarbazepine, zonisamide, pregabalin). Chronic phenytoin ingestion leads to its impact in the cerebral cortex, re...

The presence of Umar,1 a zealous Gambian Muslim in his early thirties, filled my host’s living room with a pious atmosphere. When my host offered him a seat on the couch, Umar declined, claiming that he – following the Prophet Muhammad’s example – preferred to sit on the floor. He also declined the bottle of Fanta soft drink my host offered him, saying that he preferred drinking water. As the P...

evaporation is a fundamental parameter in the hydrological cycle. this study examines the performance of m5model tree and artificial neural network (ann) models in estimating potential evapotranspiration calculated bypenman- monteith and hargreaves- samani equations. daily weather data from two meteorological stations in asemi-arid climate of iran, namely kerman and zahedan, were collected duri...
