Decision Support Systems, and, more recently, participatory and collaborative modelling have emerged as a response to increased focus on stakeholder participation in activities for certain fields like water resources management. Researchers practitioners frequently use 'buzzwords' such 'participatory modelling' 'collaborative modelling'. In some cases, both terms are used interchangeably, largely due unclear distinction between them literature. This article draws the line by using levels of...

Abstract. Citizen contributions to science have been successfully implemented in many fields, and water resources is one of them. Through citizens, it possible collect data obtain a more integrated decision-making process. Specifically, scarcity has always an issue flood modelling, which addressed the last decades by remote sensing already being discussed citizen context. With this mind, article aims review literature on topic analyse opportunities challenges that lie ahead. The monitoring,...

The Vietnamese Mekong Delta (VMD) has an important role in terms of food security and socio-economic development the region; however, it is one many areas world vulnerable to floods resulting from sea level rise (SLR) due climate change. Therefore, management flooding a priority at national regional levels Vietnam. Long Xuyen Quadrangle most region VMD agriculture economy. In present work, flood hazard, vulnerability risk were assessed mapped identify for mitigation. A hydrodynamic model was...

Abstract. This paper explores the use of flow length and travel time as a pre-processing step for incorporating spatial precipitation information into Artificial Neural Network (ANN) models used river forecasting. Spatially distributed is commonly required when modelling large basins, it usually incorporated in physically-based hydrological approaches. However, these approaches are recognised to be quite complex expensive, especially due data collection multiple inputs parameters, which vary...

Abstract. This paper presents an approach to enhance the role of local stakeholders in dealing with urban floods. The concept is based on DIANE-CM project (Decentralised Integrated Analysis and Enhancement Awareness through Collaborative Modelling Management Flood Risk) 2nd ERANET CRUE funding initiative. main objective was develop test advanced methodology for enhancing resilience communities flooding. Through collaborative modelling, a social learning process initiated that enhances...

Contamination emergency in water distribution systems is a complex situation where optimal operation becomes important for public health. In case of corrective operational actions flushing the pollutant out network are needed, which have to be fast and accurate. Under such stressful situation, trial-and-error simulation experiments with hydrodynamic quality models cannot applied since significant number model evaluations may required identify solution. This paper presents methodology finding...

As Egypt’s population increases, the demand for fresh groundwater extraction will intensify. Consequently, quality deteriorate, including an increase in salinization. On other hand, salinization caused by saltwater intrusion coastal Nile Delta Aquifer (NDA) is also threatening resources. The aim of this article to assess situation 2010 (since when most data sufficiently available) regarding available resources and evaluate future NDA using a 3D variable-density flow model coupled with salt...

Abstract Participatory modelling has become a growing concept in environmental modelling, as it allows stakeholders to be involved various stages of model development. The majority studies, however, have focused on the participation during use for scenario analysis and strategy evaluation after been developed. Large‐scale community mapping efforts create new opportunities establish, detail improve flood models at development stage by working together with local stakeholders. In this article,...

Abstract Development of flood risk management ( FRM ) plans and strategies should ideally be carried out in participatory processes through involvement all stakeholders. Participation can collaboration with the experts among stakeholders themselves, leading to identification commonly agreed measures or alternatives. Stakeholder participation, however, does not come without challenges hindrances (e.g. limitation financial resources, stakeholders' spatial distribution their interest...

This article presents a simulation-optimization approach for evaluating the feasibility of managed aquifer recharge (MAR) in Samail Lower Catchment, Oman. The objective is to provide maximum and extraction rate through MAR an annual cycle two successive injection recovery periods, while meeting operational system constraints such as water level, gradient, travel time. Three groundwater management problems were solved by coupling simulation model with linear programming (SLP) nondominated...

The remediation of groundwater contamination by pumping and injection is generally a long-term costly strategy. Aquifer cleanup time highly nonlinear nonconvex function rates. objective often involves minimizing or constraining the cost. Linear programming optimization cannot guarantee global solution. In this study, four (GO) algorithms, including popular genetic algorithm, are used to minimize both cost taking rates and/or well locations as decision variables. Groundwater flow...

However, analysis model simulations are hampered by insufficient uncertain knowledge actual rainfall fields. In this research reliability groundbased measurements, different satellite products their combinations tested for impact on discharge River. Two from Tropical...

Large water distribution networks require efficient use of their resources. One the ways to become more is reduce energy consumption due pumping systems [1] [2]. In European context city Milan has a large supply system for 1.3 million inhabitants and around 4.0 commuters, which supplied entirely by 26 stations. The currently supplies its ∼50,000 customers with 103 pumps are actively operated during day [3]. previous years pump scheduling algorithm been proposed utility Pressure Management...

The Nile Delta Aquifer (NDA) is threatened by salt water intrusion (SWI). This article demonstrates an approach for identifying critical salinity concentration zones using a three-dimensional (3D) variable-density groundwater flow model in the NDA. An innovative procedure presented delineation of 2010 testing different simulation periods. results confirm presence saline caused SWI north In addition, certain regions east and southwest NDA show increased levels, possibly due to excessive...

ABSTRACT Model predictive control (MPC) is an optimal strategy suited for flood of water resources infrastructure. Despite many studies on reservoir and their theoretical contribution, optimisation methodologies have not been widely applied in real-time operation due to disparities between research assumptions practical requirements. To address this gap, we include objectives, such as minimising the magnitude frequency changes existing outflow schedule. Incorporating these objectives...

Traditional water management practices, largely based on hard engineered infrastructure and highly optimized systems, are proving insufficient for adapting to the complex interplay of future climatic, environmental socio-economic conditions. The increased frequency magnitude hydrological hazards in Europe, such as multi-year drought during period 2018-2020 subsequent summer flood that hit Central Europe July 2021, have underscored need integrated management. Nature-based Solutions (NbS)...

The Panama Canal is a critical waterway for international maritime trade. canal's operations rely heavily on Gatun Lake, 425 km² reservoir situated approximately 26 m above sea level, which supplies the water required its lock system. Each lockage consumes 50 to 120 million gallons (0.19 0.45 hm3) of water, with 32 36 lockages typically occurring daily. Lake also provides drinking about half metropolitan population in Panama. Over past decade, Lake's levels have been significantly...

Effective reservoir flood control demands real-time decision-making that balances multiple objectives. However, traditional optimization approaches are often too computationally intensive and become intractable when considering dynamically changing preferences of operators, modelled as weights different This study aims to develop tractable strategies maintain performance while reducing computational complexity. We propose two data-driven based on Model Predictive Control (MPC): (1) an...
