Abstract

L. Zaggia, A. Zuliani, F. Collavini & R. Zonta CNR – Istituto di Scienze Marine, Venice, Italy Abstract An investigation on the hydrology of the drainage basin of the Venice Lagoon was conducted as a part of an extensive monitoring of the freshwater and contaminant delivery from the twelve main tributaries (DRAIN project). The importance of flood events at the scale of the individual sub-basins as well as for the whole catchment was studied in detail by comparing the discharge measured in the tributary streams and time series of rainfall inputs obtained from a specifically created data base. The main results and an overview of the relevant methodological aspects faced by the study are presented. 1 Introduction A basic understanding of the catchment hydrology is an essential prerequisite in the management of water resources, particularly for flood protection, optimisation of conservative and consumptive uses (i.e. power production and land irrigation), lowland reclamation and monitoring of conta
