Optimal location of cutoff walls for seawater intrusion

open access: yesApplied Water Science, 2021
In this paper, the simulation–optimization method is used to study the optimal location of cutoff walls for seawater intrusion. The optimization model is based on minimizing the chlorine concentration of two water sources after 50 years.

Asymmetric impact of groundwater use on groundwater droughts [PDF]

open access: yesHydrology and Earth System Sciences, 2020
Abstract. Groundwater use affects groundwater storage continuously, as the removal of water changes both short-term and long-term variation in groundwater level. This has implications for groundwater droughts, i.e. a below-normal groundwater level. The impact of groundwater use on groundwater droughts remains unknown. Hence, the aim of this study is to

Groundwater flood or groundwater-induced flood? [PDF]

open access: yesQuarterly Journal of Engineering Geology and Hydrogeology, 2012
A number of ‘groundwater flood’ events have been recorded over the Chalk aquifer in southern England since the 1994 occurrence at Chichester, Sussex. Reporting of this event and subsequent groundwater floods indicates that there are two types of groundwater flood event. Type 1 is the true groundwater flood in which the water table elevation rises above
