SEA LEVEL TRENDS IN THE HUMBER ESTUARY : A CASE STUDY

Patrick Parle

Abstract


In 1990 Posford Duvivier were commissioned by the National Rivers Authority to collect, audit and place on a database 550 years of tide data from 15 locations on and in the vicinity of the Humber Estuary, UK. As part of this project 373 years of the data, from 10 locations (key stations), were analysed for trends in relative sea level. The areas covered in the trend analysis included: linear trend estimates on yearly average high tide levels from all the key stations; an examination of variations in trends with location and time; and an examination of the correlation between high water trends, mean tide level trends and low water trends. This paper discusses the trend analysis.
