Christiaan Brunings
Christiaan Brunings (Mannheim-Neckarau, 3 November 1736 – The Hague, 16 May 1805) was a Dutch hydraulic engineer. Early life Brunings was the son of a preacher in Mannheim-Neckarau in Germany. After high school he attended the University of Heidelberg. He had to break off his studies for lack of money and found work in the vinegar works of his brother in the Netherlands. Here he met Jan Noppen (1706-1764), superintendent of the ''Hoogheemraadschap van Rijnland'' (Rijnland Water Board). He was Brunings' mentor and taught him music, mathematics, physics, astronomy and engineering. After the death of Noppen, Brunings succeeded him on 25 May 1765 in his function. Work In 1769 Brunings became Inspector General of the Government Rivers, giving more attention to water management of the upper rivers. In 1798 he was appointed head of the ''Bureau voor den Waterstaat'' (Office of Public Works), the forerunner of the ''Rijkswaterstaat''. Brunings spent more than thirty years as head o ...

Waal (river)
The Waal (Dutch name, ) is the main distributary branch of the river Rhine flowing approximately through the Netherlands. It is the major waterway connecting the port of Rotterdam to Germany. Before it reaches Rotterdam, it joins with the Afgedamde Maas near Woudrichem to form the Boven Merwede. Along its length, Nijmegen, Tiel, Zaltbommel and Gorinchem are towns of importance with direct access to the river. The river, which is the main channel in the Rhine–Meuse–Scheldt delta system, carries 65% of the total flow of the Rhine. History The name Waal, in Roman times called ''Vacalis, Vahalis'' or ''Valis'', later ''Vahal'', is of Germanic origin and is named after the many meanders in the river ( gmw, wôh, lit=crooked). It is, in turn, thought to have inspired early Dutch settlers of the Hudson Valley region in New York to name the Wallkill River after it (''Waalkil'' "Waal Creek"). The current river shows little signs of these great bends, since the river has been t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydraulic Engineers
Hydraulic engineering as a sub-discipline of civil engineering is concerned with the flow and conveyance of fluids, principally water and sewage. One feature of these systems is the extensive use of gravity as the motive force to cause the movement of the fluids. This area of civil engineering is intimately related to the design of bridges, dams, channels, canals, and levees, and to both sanitary and environmental engineering. Hydraulic engineering is the application of the principles of fluid mechanics to problems dealing with the collection, storage, control, transport, regulation, measurement, and use of water.Prasuhn, Alan L. ''Fundamentals of Hydraulic Engineering''. Holt, Rinehart, and Winston: New York, 1987. Before beginning a hydraulic engineering project, one must figure out how much water is involved. The hydraulic engineer is concerned with the transport of sediment by the river, the interaction of the water with its alluvial boundary, and the occurrence of scour an ...

Engineers From Mannheim
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professiona ...

Icebreaker
An icebreaker is a special-purpose ship or boat designed to move and navigate through ice-covered waters, and provide safe waterways for other boats and ships. Although the term usually refers to ice-breaking ships, it may also refer to smaller vessels, such as the icebreaking boats that were once used on the canals of the United Kingdom. For a ship to be considered an icebreaker, it requires three traits most normal ships lack: a strengthened hull, an ice-clearing shape, and the power to push through sea ice. Icebreakers clear paths by pushing straight into frozen-over water or pack ice. The bending strength of sea ice is low enough that the ice breaks usually without noticeable change in the vessel's trim. In cases of very thick ice, an icebreaker can drive its bow onto the ice to break it under the weight of the ship. A buildup of broken ice in front of a ship can slow it down much more than the breaking of the ice itself, so icebreakers have a specially designed hull to ...
