Multi-objective Management Of Saltwater Intrusion In Groundwater by Minh Thuan Tran Download PDF EPUB FB2

1. Introduction. Saltwater intrusion is a common environmental problem in coastal areas (Werner et al., ; Yüce, ).Coastal aquifers are hydraulically connected to the sea, which makes them highly vulnerable to contamination via saltwater intrusion. Excessive, continuous and/or unplanned groundwater withdrawal is one of the major causes of saltwater intrusion, which Cited by: 8.

Salinity intrusion management models are used to prescribe management strategies for the sustainable use of coastal aquifers by controlling salt water intrusion. Developing an optimal management model involves integrating a groundwater flow and transport simulation model within an optimization by: Saltwater intrusion has occurred to some degree in many of the coastal aquifers of the United States.

Since saltwater cannot be used to irrigate crops or be consumed by people, saltwater intrusion can be very problematic to coastal communities that rely on fresh groundwater supplies for the livelihood.

Multi-objective Optimization of Different Management Scenarios to Control Seawater Intrusion in Coastal Aquifers Article (PDF Available) in Water Resources Management 29(6) April with Surrogate model based methodologies are developed for evolving multi-objective management strategies for saltwater intrusion in coastal aquifers.

Two different surrogate models based on genetic programming (GP) and modular neural network (MNN) are developed and linked to a multi-objective genetic algorithm (MOGA) to derive the optimal pumping strategies for coastal aquifer management Cited by: Saltwater intrusion management problems are necessary to be multi-objective.

In this work, the multi-objective management schemes that are based on the minimization of the operational costs and the saltwater intrusion length as their objectives are proposed for the first time. Zimmerman noted two points often glossed over in the public debate about the aquifer: 1) simply moving groundwater wells miles from existing saltwater intrusion could mean costly new.

Groundwater Quantity and Quality Management presents the best of current thinking on managing groundwater resources, focusing on the interrelationship between quantity and quality.

Groundwater is an essential resource, yet it is subject to overuse and contamination both in. 4 Keywords: seawater intrusion, simulation-optimization, multi-objective genetic algorithm, treated wastewater, management scenarios5 6 1.

– Groundwater is valuable to supply fresh water to the public, industries, agriculture, etc. However, excessive pumping has caused groundwater storage degradation, water quality deterioration and saltwater intrusion problems. Reliable groundwater flow and solute transport modeling is needed for sustainable groundwater management and aquifer remediation design.

The developed 3D saltwater intrusion model, predictive capability of the developed SVR models and the feasibility of using the proposed linked multi-objective SVR–MOGA optimization model makes the proposed methodology potentially attractive in solving large scale regional saltwater intrusion management problems.

Inappropriate management of a coastal aquifer may lead to its destruction as a source for freshwater much earlier than other aquifers which are not connected to the sea. The reason is the threat of seawater intrusion. In many coastal aquifers, intrusion of seawater has become one of the major constraints imposed on groundwater s: 2.

Roger Luyun Jr. Corresponding Author.Two multi-objective management models are applied on a local area selected from the regional Gaza coastal aquifer. The objectives and constraints of these management scenarios include maximizing the total volume of water pumped, minimizing the salt concentration of the pumped water, and controlling the drawdown limits.
