A new agricultural flood losses prediction method using digital elevation data combined with agricultural economic data is presented. The method is based on dynamically simulating the procedure of flood out. An example in Huangdunhu flood detention area, Jiangshu province of China has been given to describe how to use it to predict the incoming agricultural losses. Compared with prior methods, ...

Considering characteristics of high river density, special underlying surface in plain river network region, and municipal drainage system function, river network drainage unit model is proposed, which is defined as a region surrounded by main river or embankment. Flood storage variety and control projects regulation of small rivers in each unit is simulated. With drainage catchment as an objec...

rural community and their services, productive activities, because of strong relation with environment, from long bygone were exposed to disastrous natural power. therefore residents of every region by experiment, apply the approaches and measurement to contrast with these events and reduce the damage of them in their community. public attention focused on physical factor and human making envir...

the main aim of the current paper is to discuss the important effective variables, particularly synoptic patterns, in creating flood in masoule basin using flood discharge data in komadoul station during 20 year period (1984-2003). to achieve the aim, daily average and instantaneous maximum of discharge in mentioned station were used. data accuracy was done using the data for chomesghal station...

Flood risk analysis is more complex in urban areas than that in rural areas because of their closely packed buildings, different kinds of land uses, and large number of flood control works and drainage systems. The purpose of this paper is to propose a practical framework for flood risk analysis and benefit assessment of flood control measures in urban areas. Based on the concept of disaster ri...

New field evidence and discharge calculation procedures provide new estimates of maximum late Pleistocene glacial Lake Missoula flood discharges for two important reaches along the flood route. Within the Spokane Valley, near the point of release, the peak discharge probably exceeded 17 ± 3 million m-sec. Downstream at Wallula Gap, a major point of flow convergence, peak discharge was about 10 ...

Distributed denial-of-service attacks on public servers have recently become a serious problem. To assure that network services will not be interrupted, we need faster and more effective defense mechanisms to protect against malicious traffic, especially SYN floods. One problem in detecting SYN flood traffic is that server nodes or firewalls cannot distinguish the SYN packets of normal TCP conn...

the scientific community agrees that climate change is one of the greatest challenges that oursociety will have to face this century. indeed, the fourth report from the intergovernmental panel on climatechange (ippc) confirms the certitude of this phenomenon and its impacts, which can range from droughts tofloods, health problems and food shortages. the principal objective of this paper is to a...
