The Venice Lagoon and its drainage basin form a vast system, where historical and recent cities, large and medium-small industrial districts and intensive agricultural activities coexist within a peculiar environment. The drainage basin constituted of an ensemble of tributary sub-basins with contrasting characteristics and freshwater fluxes; the hydraulic pathways are generally complex and not univocally established. With the main objectives to measure the annual freshwater discharge into the Venice Lagoon and to estimate the related load of pollutants, an intense field activity was carried out in the ambit of the DRAIN project. The 12 main tributaries of the drainage basin were monitored for more than 2 years (1998-2000), obtaining a relevant data set of hydrodynamic, physico-chemical and chemical data. Integrative investigations were also developed in a multidisciplinary approach, covering the existing knowledge gaps on the hydrology and behaviour of such a complex system. The paper describes the characteristics of the system, the selected approach to investigate it, and the main project outcomes.
威尼斯潟湖及其流域构成了一个庞大的系统，在这个独特的环境中，历史悠久的城市与现代城市、大中小型工业区以及密集的农业活动并存。流域由一系列具有不同特征和淡水流量的支流子流域组成；其水力路径通常很复杂，且尚未明确确定。为了实现测量每年流入威尼斯潟湖的淡水流量以及估算相关污染物负荷的主要目标，在“排水”项目的范围内开展了密集的实地活动。对流域的12条主要支流进行了为期两年多（1998 - 2000年）的监测，获得了一套有关水动力、物理化学和化学数据的重要数据集。还采用多学科方法开展了综合调查，以填补关于这一复杂系统的水文和行为方面的现有知识空白。本文描述了该系统的特征、用于研究它的选定方法以及主要项目成果。
