Flood maps and plans

Flood means the temporary covering by water of land not normally convered by water ( 2007/60 EC). There are various flood types, which differs regarding to the water source (e.g. rainwater, groundwater, stream water) their duration (short (minutes to hours) or long (weeks to months)) or to their location (e.g. coastal floods). One possible classification of flood types is listed below: Flash ...

What are the true costs of rising sea levels?

A simple relationship between sea level rise and the massive potential costs of future coastal flooding has been established by scientists in Germany. As sea levels rise, the damage to human economies rises even faster. And as sea levels rose by an estimated 14cms in the last century, and could rise by up to 130cms in this century, the coastal cities of the world could face huge bills for storm ...

Benefits of Amphibious Vehicles During Flooding Events

Recent storms, including Hurricane Sally and Tropical Storm Beta, have brought a lot of flooding to the Gulf Coast. According to experts, the flooding was not only a result from the at times torrential rains, but also from storm surges. In Louisiana, areas outside the levee protection system were hit especially hard. Sally brought serious flooding to Pensacola where the surge heights reached 5.6 ...

Be Prepared for Flooding

What are some reasons for flooding? There are many reasons for flooding and not all flooding causes damage or is catastrophic. Flooding mostly occurs when stream or river systems fill beyond their capacity. It can also happen on lake or coastal shorelines during periods of high water levels encroach on flood plains or low-lying areas. The intensity and duration of precipitation saturates the ...

Efficient joint probability analysis of flood risk

Flood attributes such as the water level may depend on multiple forcing variables that arise from common meteorological conditions. To correctly estimate flood risk in these situations, it is necessary to account for the joint probability distribution of all the relevant forcing variables. An example of a joint probability approach is the design variable method, which focuses on the extremes of ...
