Assessment of potential seawater intrusion in a coastal aquifer system at Abomey - Calavi, Benin

Abstract: Severe sea-water intrusion can be detected several kilometers inland and represents a high risk for coastal region groundwater. The coastal aquifer of the continental terminal of the township of Abomey-Calavi (Benin) has been highly exploited for intensive drinking water capture to supply the most important cities of Abomey-Calavi, S em e and Cotonou in Benin. During the past 15 years, extracted water quantities for drinking water supply to those cities rose to the point where saline intrusion was suspected. T… Show more

“…The city of Cotonou, located on the Atlantic littoral, is one of many regional examples currently facing such challenges. The city currently draws significant groundwater resources from the Godomey pumping field (see Figure 4.2); however, the past two decades have seen an gradual increase in the salinity of the city's main wells due to a suspected saltwater intrusion [36,39]. As illustrated in Figure 4.2, saltwater potentially intrudes from the Atlantic Ocean, but more likely from Lake Nokoué to the southeast.…”

“…Semakin mendekati laut karakteristik air tanah mendekati payau hingga asin. Karakteristik air tanah pesisir yang dominan payau memiliki nilai daya hantar listrik yang relatif tinggi selain dari sifat fisik mempunyai rasa asin (Febriarta et al, 2018;Hounsinou, 2020) Air tanah di kawasan pesisir sangat dinamis, faktor yang mempengaruhi antara lain jarak terhadap laut, kedalaman air tanah, porositas batuan, dan aktivitas manusia diatasnya (Purnama, 2010). Musim juga mempengaruhi dinamika tersbut, dimana pada musim kemarau memiliki potensi intrusi air laut lebih besar dari pada musim penghujan (Hounsinou, 2020).…”

Intrusi air laut merupakan pertistiwa masuknya air laut kedalam akuifer air tanah tawar diakibatkan oleh dorongan atau tekanan air laut dimana dapat diakibatkan oleh rongga akuifer air tanah tawar kosong (Purnama, 2010;Suharno et al, 2015).…”
