It is very important to make hydrological time series modeling on water resource engineering and the decision making strategies of water resource management. In this paper, a comprehensive study on the application of Levenberg-Marquardt optimization algor... see more

The combination of wavelet analysis methods with data-driven models is a prevalent approach to conducting hydrological time series forecasting, but the results are affected by the accuracy of the wavelet decomposition of the series. The choice of decompos... see more

It is well known that daily estimates of GPS coordinates are highly temporally correlated and that the knowledge and understanding of this correlation allows to establish more realistic uncertainties of the parameters estimated from the data. Despite this... see more

Long records (1960–2013) of monthly streamflow observations from 8 hydrological stations in the East Asian monsoon region are modeled using a nonstationarity framework by means of the Generalized Additive Models in Location, Scale and Shape (GAMLSS). Mode... see more

Hydrological series are largely characterized by a strong random component in their behavior. More noticeable changes in the behavior patterns of rainfall/runoff temporal series are recently being observed. These modifications are not a trivial issue, esp... see more

This paper analyzes the potential of a nu-support vector regression (nu-SVR) model for the reconstruction of missing data of hydrological time series from a sensor network. Sensor networks are currently experiencing rapid growth of applications in experim... see more

Hydrology, as science, refers to the study of the hydrological cycle. This comprises hydrological processes that can be analyzed over time, space, or both together, which, in their turn, are quantitatively described by hydrological variables and represent... see more

DOI: 10.12957/cadest.2019.50174The Brazilian Power Sector consider flood prevention in the operation by reserving during the rainy season empty volumes in its hydropower reservoirs. The currently used flood control methodology assumes seasonal stationarit... see more

Traditional methods, autoregressive moving average models ARMA(p,q), Fiering, Svanidze, among others, have been successfully used in estimating hydrological time series such as flows, inflow volumes to reservoirs, series with a winter component, precipita... see more
