The use of computational intelligence base models in suspended sediment load estimation (Case study: Gillan province)

Maryam Asadi; Ali Fathzadeh

Volume 71, Issue 1 , June 2018, , Pages 45-60


  Understanding of suspended sediment rate is one of the fundamental problems in water projects which water engineers consistently have involved with it. Wrong estimations in sediment transport cause incorrect design and destruction of hydraulic systems. Due to the difficulty of suspended sediment measurements, ...  Read More

Assessing of interpolation methods in order to snow water equivalent estimation

Sharbanoo Abbasi Jondani; Ali Fathzadeh

Volume 68, Issue 4 , January 2016, , Pages 779-793


  Snow is one of the main components of hydrological cycle in most of mountainous basins. Since collecting the snow data (e.g. snow water equivalent data) is very difficult and time consuming, some effort is necessary to develop methods to estimate spatially variation of snow depth distribution. In the ...  Read More

Statistical Analysis of Hydrological Regime Changes in Rivers of Western Part of Orumieh Lake Basin

Mehdi Teimouri; Ali Fathzadeh

Volume 65, Issue 3 , December 2012, , Pages 315-328


  The discharge data used for hydrological modeling should be the long-term suitable random data without trend and jump which is followed a specific statistical distribution. In this study, the above mentioned conditions were evaluated for 31 years period (1974-2004) of annual mean discharge data of 10 ...  Read More
