Integrated Water Resources Management (IWRM) faces increasing complexity due to conflicts among water users, regulatory pressures, and rising energy demands for water provision. The competition for water between urban and agricultural sectors is explored alongside regulatory, technological, and socio-economic factors. The proceedings from IWRM Karlsruhe 2012 highlight practical experiences in three main areas: 1. **Challenges for Future Cities and Agriculture**: Addressing the rising demand for freshwater for both population growth and agriculture risks intensifying conflicts between economic and ecological needs. Ensuring a reliable water supply for future cities necessitates advanced technical infrastructure and environmentally optimized management, emphasizing the interconnection between water and energy and the importance of water reuse. 2. **Competing Water Uses**: Water allocation must balance the needs of domestic, industrial, agricultural, and hydropower users across different regions. This competition is exacerbated by the vulnerability of supply and sanitation systems to climate extremes and potential terrorism threats. 3. **Regulatory and Policy Framework**: Water usage generates numerous externalities, making a solid legislative and regulatory framework essential for effective management of water supply, sewerage, and storm-water services. Such frameworks are crucial for safeguarding public health, promoting ec

In dieser Arbeit werden dual-orthogonal, linear polarisierte Antennen für die UWB-Technik konzipiert. Das Prinzip zur Realisierung der Strahler wird vorgestellt, theoretisch und simulativ untersucht, sowie messtechnisch verifiziert. Danach werden Konzepte zur Miniaturisierung der Strahler dargelegt, die anschließend zum Aufbau von Antennengruppen verwendet werden. Die Vorteile der entwickelten Antennen werden praktisch anhand des bildgebenden Radars und des Monopuls-Radars gezeigt.
