The database will describe the following aspects of the estuarine
morphology and hydrodynamics:
geometric description of the estuary:
length (and possible presence of landward boundaries);
convergence length (width variation along the estuary);
depth at the mouth (average, maximum);
data on the longitudinal variation of width and cross-section;
scale of velocity at the mouth (maximum, minimum; ebb and flood mean; during
spring and neap tides);
variation of the velocity scale (max, average) along the estuary;
friction (Manning-Gauckler-Strickler coefficient, Chézy coefficient);
tidal wave characteristics:
harmonic constituents (M2 ...);
phase lag (angle between high tide and high water slack, or angle between
high water and maximum flood velocity);
longitudinal salinity profiles;
salinity observed a fixed locations as a function of time;
salinity distribution over the cross-section.
This is a temporary page: we are sorry that more precise
definitions are not presented.
A short handbook describing the parameters will be prepared soon.
