Abstract
    Nutrients distribution pattern for Tudor Creek, covering the period April, May, June and July 1986 was investigated. At the beginning of the rainy season (April), a salinity gradient with low values upstream and high values towards the open sea was evident – giving the creek estuarine characteristics. After the rainy season, salinity values were more or less uniform throughout the creek. The low salinity waters near the river mouths had high nutrient concentrations which decreased gradually towards the open sea. The highest nutrient concentrations were recorded in May which also corresponded with the rainfall peak. Though river runoff is shown to be the main source of nutrients in Tudor estuary, the Coast General Hospital’s sewage system (CGHSS) is also identified as a possible local source of nutrient supply into the estuary. However, after the heavy rains, non-conservative mixing is noticed mainly due to the reduced freshwater nutrient input and nutrient loading by the CGHSS.
