Use of Neural Networks to Forecast Time Series: River Flow Modeling
"... Abstract:- This paper presents an alternative approach to time series forecasting, through use of artificial neural networks (ANNs), a relatively new concept in hydrological research. Box and Jenkins ARMAX (autoregressive moving average with exogenous inputs) models have been widely used in modeling ..."

in modeling various time series with satisfactory results. This study shows that ANNs can produce comparable, to ARMAX, and in some cases even, better forecasting results, especially for long-term prediction. By learning, through training, the underlying mapping of the time series, an ANN provides robust
A combination of Meteorological and Hydrological Models for Flood Forecasting applied to the upper river Po-basin
"... The present work deals with the coupling of meteorological models with a hydrological rainfall-runoff model for flood forecasting. In this interdisciplinary approach to mitigate hydrological disasters a rainfall-runoff model is forced by meteorological precipitation forecast from several different n ..."

Hydrology Days 2007 © Hydrology Days Stochastic modeling of Karasu River (Turkey) using the meth- ods of Artificial Neural Networks
"... Abstract: Engineering project design, environmental impact analysis and water re-sources problems, particularly hydrological simulation and forecasting often require the estimation of streamflow. Simulation and forecasting techniques of streamflow time series have been applied widely for determining ..."

The ANN ap-proaches used in this study are well known one-hidden layer feed forward back propagation (FFBP) architecture trained with the error back propagation and a variant
Measuring Predictability of Daily Streamflow Processes Based on Univariate Time Series Model
"... Abstract: Predictability is an important aspect of the dynamics of hydrological processes. The predictability of streamflow processes can be estimated based on the multivariate approach, which takes multiple explanatory variables into consideration, or, based on a univariate time series approach, wh ..."

In this study we investigate the predictability of 31 daily average discharge series with different drainage areas observed in 8 river basins in Europe and northern America on the basis of univariate time series approach
GIUH Based Transfer Function for Gomti River Basin of India
"... Geomorphologic instantaneous unit hydrograph (GIUH) can be used as a transfer function for modeling the transformation of excess rainfall into surface runoff, in which excess rainfall is an excitation (i.e. production function) to the hydrologic system. These models can be used to predict / forecast ..."
