Optimized Use Of Water From Multiple Sources In Micro Water Grid Systems: A Modeling Approach, Hyeongrak Cho, Jungwoo Jung, Sangho Lee, Soo Kwen Chae
International Conference on Hydroinformatics
Micro water grid (MWG) is a novel approach to allow high reliability, diversification of water sources, low energy consumption, and cost reduction. Although it is not well-defined, it has potential for efficient management of urban water. MWG is suitable for use in small-scale buildings and towns, which have various uses of water produced from multiple source waters. Accordingly, design of MWG is challenging without proper tools to predict its performance. This research focused on the development and application of a model for optimized use of water from multiple sources in MWG systems. The model was comprised of two modules including …

Traditionally, the relationship between flow rate and sediment concentration in rivers has been estimated empirically. However, the problem of empirical data collection is that it is often difficult to cover the entire range of flow rates. Especially higher flow rates are often undersampled, which might lead to an underestimation of modelled sediment transport as flood events are often associated with important erosion events. In order to overcome this limitation, the introduction of the transport capacity concept can establish a safe upper bound of this sediment transport relationship. Nevertheless, given the number of implied variables in this equation, there is a …

Controlling the evolution of a reservoir in a flood episode can be critical, especially in Mediterranean basins where the concentration time is very short. In this situation, an automatic software tool can help the reservoir manager to make a quick decision. In this paper we present a DSS based on the execution of formal models by means of model checking. This technique exhaustively explores the different execution branches of a model of the system. The DSS addresses two flood control tasks. First, the DSS simulates the evolution of the reservoir (the water stored and released) when applying a predefined flood …
A Model To Structure Scientific Information For Decision Makers, Rebecca Kristine Schmidt, Damian Barrett, Simon Gallant
A Model To Structure Scientific Information For Decision Makers, Rebecca Kristine Schmidt, Damian Barrett, Simon Gallant
International Conference on Hydroinformatics
Scientific information for decision makers needs to be discoverable and transparent so that decisions are more easily based on scientific evidence. One way to achieve these goals is to specify a robust model that structures this scientific information. This paper presents a model that governs the scientific activities, inputs and products for bioregional assessments (BAs), which provide information on the ecology, hydrology, geology and hydrogeology of a bioregion with explicit assessment of the potential direct, indirect and cumulative impacts of coal seam gas and coal mining development on water resources. This scientific information will be available for all interested parties …

Introduction Environmental models are often provided in the form of software solutions, with different levels of complexity. The simplest form is an executable file reading the model setup and boundary conditions from input files, doing the calculations and generating output files with model results. Preparing input files and reading output files requires to know and respect model specifics such as file formats and calling conventions. This "user-unfriendliness" may discourage the usage of models in this simplest form. However, these models may offer great opportunities since they are often freely available and contain the pure model "core" being fast in execution. …
