Natural disasters like floods are a worldwide phenomenon and a serious threat to mankind. Flood simulations are applications of disaster control, which are used for the development of appropriate flood protection. Adequate simulations require not only the geometry but also the roughness of the Earth’s surface, as well as the roughness of the objects hereon. Usually, the floodplain roughness is ...

This study evaluated multiple aspects of flood risks and effects on the Cinan Feizuo protection area in Huaihe River basin. Flooding remains a leading problem for infrastructure, especially urban, residential areas region. Effective modeling urbanized floodplains is challenging, but MIKE (ID-2D) paramount analyzing quantifying risk vulnerable The Saint-Venant equation one-dimensional (1D) 11 mo...

Detention rockfill dams are accounted as economically efficient structures for flood control, river bed and banks protection, flow diversion, etc. As the hydraulic behavior of these structures, when are used for flood control, is affected by the depth of water in their porous media, there is interests to predict water surface profile through the body of these structures. In this research, we de...

There is considerable effort to cover the broad variety of types of risk including natural disaster risk, technical disaster risk, biological disaster risk, transport and energy, research and innovation, critical infrastructure protection, cross-border health threats, implications for the health service systems, environmental impact assessment, green infrastructure, integrated coastal managemen...

Soil moisture monitoring and the characterization of the spatial and temporal variability of this hydrologic parameter at scales from small catchments to large river basins continues to receive much attention, reflecting its critical role in subsurface – land surface – atmosphere interactions and its importance to drought analysis, crop yield forecasting, irrigation planning, flood protection, ...

For close to 70 years, the Natural Resources Conservation Service (NRCS) has provided seasonal water supply outlooks for use by Western US water managers. These outlooks are a critical component in effective water management and are utilized by a broad spectrum of users for a variety of purposes, ranging from irrigated agriculture, flood control, municipal water supply, endangered species prote...

More and more natural disasters are happening every year: floods, earthquakes, volcanic eruptions, etc. In order to reduce the risk of possible damages, governments all around the world are investing into development of Early Warning Systems (EWS) for environmental applications. The most important task of the EWS is identification of the onset of critical situations affecting environment and po...

Cyber attacks are continuing to hamper working of Internet services despite increase in the use of network security systems such as, firewalls and Intrusion protection systems (IPS). Recent Denial of Service (DoS) attack on Independence Day weekend, on July 4th, 2009 launched to debilitate the US and South Korean governments’ websites is indicative of the fact that the security systems may not ...
