The regular arrival of incoming waves in the near shore waters causes the development of waves perpendicular to the direction of the incoming waves; these are termed 'edge waves'. These edge waves become trapped near the shoreline and when two of them come together from opposite directions, a standing edge wave is formed.

The Netherlands has a large area of polders: as much as 20% of the land area has at some point in the past been reclaimed from the sea, thus contributing to the development of the country. IJsselmeer is the most famous polder project of the Netherlands. Some other countries which have polders are Bangladesh, Belgium, Canada and China.
The natural slope of the flood plains is often very small, and little fall (or head loss) is permissible in the culverts. Researchers developed and patented the design procedure of minimum energy loss culverts which yield small afflux. [21] [22] [23] A minimum energy loss culvert or waterway is a structure designed with the concept of minimum ...
A most serious objection to the formation of continuous, high embankments along rivers bringing down considerable quantities of detritus, especially near a place where their fall has been abruptly reduced by descending from mountain slopes onto alluvial plains, is the danger of their bed being raised by deposit, producing a rise in the flood ...
The low-lying areas (dark blue) defended by the river walls, where 1.25 million people live or work. (After Lavery & Donovan, 2005.) (After Lavery & Donovan, 2005.) The tidal Thames today is virtually a canal [ 14 ] [ 2 ] —in central London, about 250 metres wide—flowing between solid artificial walls, and laterally restrained by these at ...
