Application of Artificial Neural Networks to Project Reference Evapotranspiration Under Climate Change Scenarios
Springer Science and Business Media LLC - Tập 36 - Trang 835-851 - 2022
Evapotranspiration is sensitive to climate change. The main objective of this study was to examine the response of reference evapotranspiration (ET0) under various climate change scenarios using artificial neural networks and the Canadian Earth System Model Second Generation (CanESM2). The Hargreaves method was used to calculate ET0 for western, central, and eastern parts of Prince Edward Island u......
Regression Kriging Analysis for Longitudinal Dispersion Coefficient
Springer Science and Business Media LLC - Tập 27 - Trang 3307-3318 - 2013
Prediction of longitudinal dispersion coefficient (LDC) is still a novel topic for both environmental and water sciences due to its practical importance. In this study, the appraisal of LDC is considered as a spatial modelling problem and the analyses are carried out by regression kriging. Since LDC prediction includes some geometrical (spatial) parameters, the analyses have been performed such th......
Drought Vulnerability Assessment Based on a Multi-criteria Integrated Approach and Application of Satellite-based Datasets
Springer Science and Business Media LLC - Tập 36 - Trang 3839-3858 - 2022
Drought as a complex event depends on some geo-environmental parameters. The impact of this phenomenon on the economy and environment can be devastating. Recognizing drought-prone regions is essential for planning and adopting mitigation measures. This study focused on introducing a multiscale method based on the satellite datasets to assess drought vulnerability in non-gage areas. In this regard,......
Flood Attenuation Potential of Italian Dams: Sensitivity on Geomorphic and Climatological Factors
Springer Science and Business Media LLC - - 2023
In this work the attenuation potential of flood peaks of 265 large reservoirs all over Italy is analysed, considering a flood management that excludes gates opening and then configures strictly unsupervised attenuation effects. Key factors of dams and related basins are considered to develop a ranking method that can emphasize the interplay between dam geometry and the hydrological processes actin......
Watershed Management Benefits in a Hypothetical, Real Intention and Real Willingness to Pay Approach
Springer Science and Business Media LLC - - 2017
Despite growing knowledge of a disparity between stated and actual willingness to engage in pro-environmental behavior, little is known about the cognitive or attitudinal factors explaining the disparity. In the context of water quality improvement in a river basin, we address the disparity issue by applying two approaches: a typical valuation question with a hypothetical option of voluntary payme......
Decomposition-ANN Methods for Long-Term Discharge Prediction Based on Fisher’s Ordered Clustering with MESA
Springer Science and Business Media LLC - Tập 33 - Trang 3095-3110 - 2019
Precise and reliable long-term streamflow prediction contributes to water resources planning and management. Artificial neural network (ANN) have shown its remarkable ability in forecasting non-linear hydrological processes without involvement of complex, dynamic, hydrological and hydro-climatologic physical process in the water shed. To improve its non-stationary responses, decomposition methods ......
Knowledge and Perceptions in Participatory Policy Processes: Lessons from the Delta-Region in the Netherlands
Springer Science and Business Media LLC - Tập 23 - Trang 1641-1663 - 2008
Water resources management issues tend to affect a variety of uses and users. Therefore, they often exhibit complex and unstructured problems. The complex, unstructured nature of these problems originates from uncertain knowledge and from the existence of divergent perceptions among various actors. Consequently, dealing with these problems is not just a knowledge problem; it is a problem of ambigu......
Improving Urban Drainage Systems Resiliency Against Unexpected Blockages: A Probabilistic Approach
Springer Science and Business Media LLC - Tập 32 - Trang 4561-4573 - 2018
Considering the increase of flood hazards in many large cities, the rehabilitation of hydro-urban infrastructures is an important concern for the municipal authorities. A probabilistic approach based on Monte Carlo Simulation (MCS) is presented in this study to improve the resiliency of urban drainage systems when they are subject to unexpected structural blockages. The approach is integrated with......
Assessing Subaquatic Mass Movement Hazards: an Integrated Observational and Hydrodynamic Modelling ApproachAbstract High-resolution lake and reservoir bathymetric surveys can pinpoint locations that may experience underwater landslides (subaquatic sedimentary mass movements). These can pose a risk to underwater and shoreline infrastructure. This paper outlines an approach for using spatial variation in sedimentary patterns to identify areas susceptible to subaquatic mass... ...

Modeling the Yield–Evaporation–Spill in the Reservoir Storage Process: The Regulation Triangle Diagram
Springer Science and Business Media LLC - Tập 24 - Trang 3487-3511 - 2010
From the dimensionless reservoir water budget equation, a graphical method to model the yield–spill–evaporation loss trade-off in the reservoir storage process was built. The reservoir inflows were transformed into three parts that sum to the total mean inflow for long-term operation: evaporation, spill and yield. A regulation triangle diagram (RTD) has been proposed to provide a better understand......
