INVESTIGATION OF PAST AND FUTURE SEA-LEVEL CHANGES AND THEIR IMPACTS

Objective

TO STUDY THE MECHANISMS AND IMPACTS OF SEA-LEVEL CHANGES IN EUROPE.

THE PROGRAMME OF RESEARCH INTO EUROPEAN SEA LEVELS CAN BE DIVIDED INTO FOUR MAJOR PARTS:
PART 1 - AN INVESTIGATION OF EUROPEAN SEA LEVEL TRENDS USING GEOLOGICAL AND ARCHAEOLOGICAL DATA FROM THE RELATIVELY RECENT PAST.

PART 2 - A SET OF ANALYSES OF EUROPEAN TIDE GAUGE DATA FROM THE LAST TWO CENTURIES.

PART 3 - PREDICTIONS OF THE AMPLITUDES AND TIMESCALES OF FUTURE SEA LEVEL CHANGE TOGETHER WITH ESTIMATES OF CHANGE IN THE FREQUENCY AND MAGNITUDE OF STORM SURGES.

PART 4 - AN ASSESSEMENT OF THE POTENTIAL TYPES OF IMPACTS ON COASTAL AREAS DUE TO FUTURE SEA LEVEL RISE AND THEIR GEOGRAPHICAL DISTRIBUTION TOGETHER WITH A SURVEY OF THOSE AREAS OF EUROPE ALREADY EXPERIENCING SIGNIFICANT RATES OF CHANGE IN SEA LEVEL.
IN PART 1.1 ASSISTANCE WILL BE GIVEN TO THE UPDATING OF THE SEA LEVEL DATABASE. IN PART 1.2 SEDIMENTOLOGICAL STUDIES OF COASTAL BARRIER DEPOSITS ON DUTCH WADDEN, SEA ISLANDS WILL BE CARRIED OUT; THESE WILL PROVIDE VALUABLE INFORMATION ON MEAN HIGH AND LOW WATER LEVELS AND THEIR CHANGES OVER THE LAST 2000 YEARS.
IN PART 2.1 RIJKSWATERSTAAT WILL REVIEW THE QUALITY OF ITS OWN PRESENT DATA AND SEARCH FOR HISTORICAL DUTCH DATA NOT AT PRESENT HELD. IN ADDITION CONTACTS WITH HYDROLOGICAL SERVICES IN NEIGHBOURING COUNTRIES WILL BE KEPT AND AS FAR AS POSSIBLE AND USEFUL CLOSE COOPERATION WITH THESE SERVICES WILL BE REALIZED. IN PART 2.2 SPECIAL ATTENTION WILL BE PAID TO REDUCTION OF NOISE IN SERIES OF MEAN SEA LEVEL, MEAN HIGH AND MEAN LOW WATER LEVELS (FOR WHICH METEOROLOGICAL AND HYDROLOGICAL INFLUENCES - SUCH AS AIR PRESSURE, WATER TEMPERATURE AND DISCHARGES OF THE MAIN RIVERS RHINE AND MEUSE - WILL BE STUDIED), WHILST PART OF THE ANALYSIS OF TRENDS AND BREAKS WILL BE DETECTION OF INFLUENCES GREAT CIVIL ENGINEERING WORKS (CARRIED OUT FROM 1860 ONWARD) POSSIBLY HAD.FOR BOTH PARTS 2.1 AND 2.2 STUDY OF INTERRELATIONSHIPS OF ADJACENT GAUGES - PARTLY WITH RATHER SHORT SERIES OF DATA - WILL BE MADE.
