Groundwater-associated anthropogenic influence on coastal lagoons: Diani and Nyali Beach, Kenya

Abstract

The general aim of the study was to elucidate the importance of groundwater as a vector of anthropogenic inputs into the coastal zone. In order to achieve this, research work was planned and approached in two fronts: (a) nutrient dynamics studies and (b) microbiological water quality studies. The study was conducted in two main areas viz. Nyali and Diani. Although it had been expected that one of these areas would be a groundwater outflow area and the other an intrusion area, they both turned out to be outflow areas. A third station, Kenyatta beach had to be included to serve as an intrusion area for comparative purposes.
