Rice blast, caused by Magnaporthe grisea Cav., frequently limits rough rice yields and cultivar options in Arkansas rice production areas. Rice growers and researchers have long observed that susceptible rice plants are more blast resistant when growing in moisture saturated or flooded soil. In fact, Arkansas growers utilized flood-induced field resistance as their primary blast control measure...

To create the final spatial information and analysis, flood hazard maps and land development priority maps and information, data for the flood events to 2009 in north of Iran were incorporated with using Geo-spatial Information System data of physiographic divisions, geologic divisions, land cover classification, elevation, drainage network, administrative districts and population density and e...

Two experiments were conducted at the Delta Research and Extension Center in Stoneville, MS, during 2011 and 2012 to determine the impact of water management practices on the efficacy of insecticidal seed treatments targeting rice water weevil, Lissorhoptrus oryzophilus Kuschel. Larval densities and yield were compared for plots treated with labeled rates of thiamethoxam, chlorantraniliprole, a...

The paper presents two simulation modules –Virtual Dike and Flood Simulator– developed for flood Early Warning Systems (EWS). The UrbanFlood EWS is a distributed system that (1) analyzes sensor data received in real-time from flood defenses (dikes, dams, etc.) and (2) simulates dike stability, breaching and flood propagation. Computational modules are invoked by workflow-based expert scenarios ...

Flood disasters cause massive loss of human lives and immense damage to the infrastructure and economic activities, not only in Turkey but also all over the world. Governments consider several long-term and short-term precautions for flood control. The numerical simulation of dam-break problems could be accomplished with geographic information systems and innovation maps. Spread of the flood wa...

Social pressure on alluvial plains and deltas is large, both from an economic point of view and from a nature conservation point of view. Gradually, flood risks increase with economic development, because the expected damage increases, and with higher dikes, because the flooding depth increases. Global change, changing social desires, but also changing views, require a revision of flood-risk ma...
