https://doi.org/10.22067/jsw.v30i4.44103

Abstract
  Introduction: Time series models are one of the most important tools for investigating and modeling hydrological processes in order to solve problems related to water resources management. Many hydrological time series shows nonstationary and nonlinear behaviors. One of the important hydrological modeling ...  Read More

Investigation of Land Use Effects in Geomorphological Unit Hydrograph of Linear Reservoirs

Ahmad Fakheri Fard; Vahid Nourani; Faegheh Niazi

Volume 30, Issue 2 , May and June 2016, , Pages 377-391

https://doi.org/10.22067/jsw.v30i2.39841

Abstract
  Introduction: The influence of urbanization, as one important form of land use, on runoff and floods within watersheds has been a major topic of research during the past few decades. Urbanization affects the hydrology processes of a watershed by replacing the vegetated land cover with impervious surfaces. ...  Read More

Introducing and Application of Combined BL-ARCH Model for Daily River flow Forecasting (Case study: Shahar-Chai River)

A. Fakheri Fard; yaghoub dinpazhoh; F. Ahmadi; J. Behmanesh

Volume 27, Issue 2 , May and June 2013, , Pages 342-350

https://doi.org/10.22067/jsw.v0i0.24360

Abstract
  One of the applicable ways for simulation and forecasting hydrological processes is time series modeling. An important problem in forecasting hydrological data using time series is generating stochastic data. Any changes in stochastic series will change generating data. In this study nonlinear ARCH model ...  Read More

Prediction of Precipitation Applying Wavelet Network Model(Case study: Zarringol station, Golestan province, Iran)

P. Toufani; A. Mosaedi; A. Fakheri Fard

Volume 25, Issue 5 , November and December 2011

https://doi.org/10.22067/jsw.v0i--.11260

Abstract
  Abstract Obligatory modelling of precipitations in various periods, have a lot of problems and weakness because of their casual nature in time and space. Moreover, their uncertainty in predictions, reduce credibility of estimations which have done via these models. Wavelet is one of the novel and very ...  Read More
