Watershed characteristics such as patterns of land use and land cover (LULC), soil structure and river systems, have substantially changed due to natural and anthropogenic factors. To adapt hydrological models to the changing characteristics of watersheds, one of the feasible strategies is to explicitly estimate the changed parameters. However, few approaches have been dedicated to these non-st...

In 2008, a global production rounding 1,724 and 1,053 million metric tones respectively for walnut and hazelnut has been estimated. Bacterial diseases are threatening these nut crops all over the World. Xhanthomonas arboricola pv. juglandis (Xaj) is the agent of walnut bacteriosis, and has been associated also to brown apical necrosis. Several walnut genotypes have shown a range of tolerance to...

Floods are one of the main natural disaster threats to safety people’s lives and property. Flood hazards intensify as global risk flooding increases. The control flood disasters on basin scale has always been an urgent problem be solved that is firmly associated with sustainable development water resources. As important nonengineering measures for simulation control, hydrological hydraulic mode...

Abstract Ensemble hydrologic forecasting which takes advantages of multiple models has made much contribution to water resource management. In this study, four hydrological (the Xin’anjiang model (XAJ), Simhyd, GR4J, and artificial neural network (ANN) models) three ensemble methods simple average, black box-based, binomial-based methods) were applied compared simulate the process during 1979–1...

Assessing the impact of climate change on streamflow is critical to understanding the changes to water resources and to improve water resource management. The use of hydrological models is a common practice to quantify and assess water resources in such situations. In this study, two hydrological models with different structures, e.g., a physically-based distributed model Liuxihe (LXH) and a lu...

The Shuffled Complex Evolution—University of Arizona (SCE-UA) is a classical algorithm in the field hydrology and water resources, but it cannot solve constrained optimization problems directly. Using penalty functions has been preferred method to handle constraints, appropriate selection parameters can be challenging. To enhance universality SCE-UA, we propose Constrained Evolution Algorithm (...

The parameters of hydrological models should be determined before applying those to estimate or predict processes. Xin’anjiang (XAJ) model is widely used throughout China. Since the prediction in ungauged basins (PUB) era, regionalization XAJ has been a subject intense focus; nevertheless, while many efforts have targeted related runoff yield using in-site data sets, classic regression predomin...
