Hydrological Data for Wetland Management

Hydrology is the prime control in wetland ecosystems, but little formal hydrological data are gathered in wetlands by hydrometric authorities. Normally; most of the hydrological data for wetlands can be obtained from informal sources, non-hydrological organizations, the local population and archival information - especially photographs. Some short-term field monitoring can be useful in augmenting the large hydrological data sets which can be gathered - even when initial enquiries yield minimum information. A case study from the North Kent Marshes is used to illustrate this fact.
