本文介绍了斯海尔德河口 7 年综合监测的结果。两个数据集的结合产生了对从河口到上边界的河口水质参数的完整描述，包括扩展的淡水潮汐部分。综合监测结果和斯海尔德河所有相关生态知识，可以找到优化其管理的机会。结果表明，流量对盐度的影响在多盐到中盐过渡区具有明显的最大值。通过河口内的管理措施可以加强和改善氧条件、氮去除和浮游植物调节。然而，为了降低碳和磷负荷，应在流域内采取措施。为了恢复河口的大部分生态功能，需要更多的空间。可以从监测结果中得出解决特定功能的最佳位置。
This paper presents the results of 7 years of integrated monitoring along the Scheldt estuary. The combination of two datasets resulted in a full description of the estuaries water quality parameters from the mouth to the upper boundary, including an extended fresh water tidal part. A synthesis of the monitoring results and all relevant ecological knowledge on the Scheldt allowed to identify opportunities to optimize its management. The results show that the effect of discharge on salinity has a distinct maximum in the polyhaline to mesohaline transition area. Oxygen conditions, nitrogen removal and phytoplankton regulation can be enhanced and improved through management measures within the estuary. To lower carbon and phosphorous loads however measures should be taken within the catchment. To restore most of its ecological functions the estuary needs more space. Optimal locations to address specific functions can be derived from the monitoring results.
