Data Requirements

Modeling of integrated urban water systems (IUWS) has seen a rapid development in recent years. Models and software are available that describe the process dynamics in sewers, wastewater treatment plants (WWTPs), receiving water systems as well as at the interfaces between the submodels. Successful applications of integrated modeling are, however, relatively scarce. One of the reasons for this is the lack of high-quality monitoring data with the required spatial and temporal resolution and accuracy to calibrate and validate the integrated models, even though the state of the art of monitoring itself is no longer the limiting factor. This paper discusses the efforts to be able to meet the data requirements associated with integrated modeling and describes the methods applied to validate the monitoring data and to use submodels as software sensor to provide the necessary input for other submodels. The main conclusion of the paper is that state of the art monitoring is in principle sufficient to provide the data necessary to calibrate integrated models, but practical limitations resulting in incomplete data-sets hamper widespread application. In order to overcome these difficulties, redundancy of future monitoring networks should be increased and, at the same time, data handling (including data validation, mining and assimilation) should receive much more attention.

Object Of Study

This article took gravity wharf engineering as the object of study to explore its deformation law by using GPS positioning technology. First, we will introduce the layout of a GPS control network at the wharf and then monitor the displacement of the gravity wharf through GPS-RTK、DBS-RTK and GPS static positioning technologies separately. Comparing three groups of monitoring data, we came to the conclusion that this gravity wharf is very stable, which has also proved the feasibility to apply GPS positioning technology to the displacement monitoring of the gravity wharf.
