An RBF‐based model with an information processor for forecasting hourly reservoir inflow during typhoons
Hydrological Processes - Tập 23 Số 25 - Trang 3598-3609 - 2009
Gwo‐Fong Lin, Ming‐Chang Wu, Guorong Chen, Fei‐Yu Tsai
AbstractInflow forecasting is essential for decision making on reservoir operation during typhoons. In this paper, a radial basis function (RBF)‐based model with an information processor is proposed for more accurate forecasts of hourly reservoir inflow. Firstly, based on the multilayer perceptron neural (MLP) network, an information processor is developed to pre‐p...... hiện toàn bộ
A nonlinear data‐driven model for synthetic generation of annual streamflows
Hydrological Processes - Tập 22 Số 12 - Trang 1831-1845 - 2008
K. P. Sudheer, K. Srinivasan, T. R. Neelakantan, V. V. Srinivas
AbstractA hybrid model that blends two non‐linear data‐driven models, i.e. an artificial neural network (ANN) and a moving block bootstrap (MBB), is proposed for modelling annual streamflows of rivers that exhibit complex dependence. In the proposed model, the annual streamflows are modelled initially using a radial basis function ANN model. The residuals extracted...... hiện toàn bộ
Short‐term inflow forecasting using an artificial neural network model
Hydrological Processes - Tập 16 Số 12 - Trang 2423-2439 - 2002
Zhiheng Xu, J. Y. Li
AbstractThe primary objective of this study is to investigate the possibility of including more temporal and spatial information on short‐term inflow forecasting, which is not easily attained in the traditional time‐series models or conceptual hydrological models. In order to achieve this objective, an artificial neural network (ANN) model for short‐term inflow for...... hiện toàn bộ
Auto‐configuring radial basis function networks for chaotic time series and flood forecasting
Hydrological Processes - Tập 23 Số 17 - Trang 2450-2459 - 2009
Li‐Chiu Chang, Fi‐John Chang, Yuanpeng Wang
AbstractThe learning strategy of the radial basis function network (RBFN) commonly uses a hybrid learning process to identify the structure and then proceed to search the model parameters, which is a time‐consuming procedure. We proposed an evolutionary way to automatically configure the structure of RBFN and search the optimal parameters of the network. The strate...... hiện toàn bộ
Assessing the effect of climate change on mean annual runoff in the Songhua River basin, China
Hydrological Processes - Tập 26 Số 7 - Trang 1050-1061 - 2012
Dejia Meng, Xingguo Mo
AbstractInfluences of climatic change on the components of global hydrological cycle, including runoff and evapotranspiration are significant in the mid‐ and high‐latitude basins. In this paper, the effect of climatic change on annual runoff is evaluated in a large basin—Songhua River basin which is located in the northeast of China. A method based on Budyko‐type e...... hiện toàn bộ
A classification of drainage and macropore flow in an agricultural catchment
Hydrological Processes - Tập 16 Số 1 - Trang 27-46 - 2002
Catherine Heppell, Fred Worrall, T. P. Burt, Richard J. Williams
AbstractThis paper uses a variety of multivariate statistical techniques in order to improve current understanding of the antecedent and rainfall controls on drainage characteristics for an agricultural underdrained clay site. Using the dataset obtained from a two‐year hillslope study at Wytham (Oxfordshire, UK) a number of patterns in the nature and style of drain...... hiện toàn bộ
Improving interpolation of daily precipitation for hydrologic modelling: spatial patterns of preferred interpolators
Hydrological Processes - Tập 23 Số 23 - Trang 3281-3291 - 2009
Daniel Kurtzman, Shilo Navon, Efrat Morin
AbstractDetailed hydrologic models require high‐resolution spatial and temporal data. This study aims at improving the spatial interpolation of daily precipitation for hydrologic models. Different parameterizations of (1) inverse distance weighted (IDW) interpolation and (2) A local weighted regression (LWR) method in which elevation is the explanatory variable and...... hiện toàn bộ
The influence of macrophyte growth, typical of eutrophic conditions, on river flow velocities and turbulence production
Hydrological Processes - Tập 20 Số 18 - Trang 3915-3938 - 2006
Pamela S. Naden, P. Rameshwaran, Owen Mountford, Coralie Robertson
Teleconnection and climatic oscillation in aquifer water level in Kumamoto plain, Japan
Hydrological Processes - Tập 29 Số 7 - Trang 1687-1703 - 2015
Linyao Dong, Jun Shimada, Makoto Kagabu, Congsheng Fu
AbstractRelative little is known about the interaction between climate change and groundwater. Analysis of aquifer response to climatic variability could improve the knowledge related to groundwater resource variations and therefore provides guidance on water resource management. In this work, seasonal and annual variations of groundwater levels in Kumamoto plain (...... hiện toàn bộ
Isotopic variation in the lake water balance at the Yamdruk‐tso basin, southern Tibetan Plateau
Hydrological Processes - Tập 22 Số 17 - Trang 3386-3392 - 2008
Lide Tian, Zhongfang Liu, Tongliang Gong, Changliang Yin, Wusheng Yu, Tandong Yao
AbstractThe use of stable isotopes is a practical tool in the study of the lake water budget. This is an one way to study the hydrological cycle in the large numbers of inland lakes on the Tibetan Plateau, in which the isotope record of the sediment is believed to reflect the climatic and environmental changes. The monitoring of stable isotopes of the precipitation...... hiện toàn bộ
