A comparison between artificial neural network method and nonlinear regression method to estimate the missing hydrometric data

Abstract: Missing values are a common problem faced in the analysis of hydrometric data. The need for complete hydrological data, especially hydrometric data for planning, development and designing hydraulic structures, has become increasingly important. Reasonably estimating these missing values is significant for the complete analysis and modeling of the hydrological cycle. The major objective of this paper is to estimate the missing annual maximum hydrometric data by using According to the coefficient of determinatio… Show more

“…For this reason, a technique capable of generating realistic simulations of the missing data, reflecting the complex structures of the signal, and possibly making use of auxiliary information, is needed. 10 Many different approaches have been proposed for time-series gap filling in earth sciences: techniques based on mean diurnal variation or regression Falge et al (2001); Moffat et al (2007), autoregression Bennis et al (1997); Wang (2008), singular spectrum analysis Schoellhamer (2001) ;Kondrashov et al (2014), self-organizing maps Wang (2003); Lamrini et al (2011), look-15 up tables Bamberger et al (2014), rough sets Dumedah et al (2014), and artificial neural networks, widely used in recent years Aminian and Ameri (2005); Dastorani et al (2009);Diamantopoulou (2010); Nkuna and Odiyo (2011); Bahrami et al (2011);Nourani et al (2012); Dumedah et al (2014).…”

“…The missing hydrometric data were investigated and predicted by Bahrami et al using the artificial neural network method and nonlinear regression method. Based on some performance indices, the results showed that ANN could be applied as an appropriate tool for predicting the missing data [22]. Based on intact rocks' behavior and some carbonate rocks' properties, the relationship between slake durability cycles on the prediction of uniaxial compressive strength and modulus of elasticity was evaluated by Yagiz et al using artificial neural network and nonlinear regression techniques.…”
