The sustained and cost-effective monitoring of the water quality within European coastal areas is of growing importance in view of the upcoming European marine and maritime directives, i.e. the increased industrial use of the marine environment. Such monitoring needs mechanisms/systems to detect the water quality in a large sea area at different depths in real time. This paper presents a system for the automated detection and analysis of water quality parameters using an autonomous underwater vehicle. The analysis of discharge of nitrate into Norwegian fjords near aqua farms is one of the main application fields of this AUV system. As carrier platform the AUV "CWolf" from the fraunhoferiosb-ast will be used, which is perfectly suited through its modular payload concept. The mission task and the integration of the payload unit which includes the sensor module, the scientific and measurement computer in the AUV carrier platform will be described. Few practice oriented information about the software and interface concept, the function of the several software modules and the test platform with the several test levels to test every module will be discussed.

Environmental modelling workflows are often tedious due to heterogeneity of data sources, types and formats. This paper discusses how a software framework based on Open Geospatial Consortium (OGC) standards may facilitate the workflow steps and improve their flexibility by supporting data access, processing, and decision-making. The software framework is designed based on OGC standards, which can be realized in any modern programming language, to encapsulate processing algorithms (so called fusors) that fuse the environmental input data and run a model based computation. Such a software framework can improve the integration of new data sources into environmental applications as well as the data exchange between scientists who can then focus on the real application problem at hand. The open source model MODFLOW, which is worldwide one of the standard codes for groundwater flow simulation, is taken here as an example data fusor. A further objective of this software framework is to offer the complete modelling workflow as a web service.

Sustainable management of water resources and a safe supply of drinking water will play a key role for the development of the human prosperity in the following *** paper presents an optimal control approach for the management of the total water resources in a fast developing region under a critical water shortage.A model of the water allocation system is developed which considers both surface and groundwater resources and the distribution *** spatially distributed groundwater model is considered as a reduced model of the complex 3D Finite Element *** the optimization problem,which is formulated as large scale structured non-linear programming problem,can be solved in an appropriate computation *** performance of the proposed concept is demonstrated by close to reality optimization scenarios.
