    International Journal of Korean History (Vol.20 No.1, Feb. 2015) 47 Hydraulic Theory and Hydraulic Engineering Projects of the Wusong River (吳淞江) Basin Between the Sixteenth and Nineteenth Centuries* Chung Chulwoong** Introduction There are a number of diverse research topics and an abundance of research concerning the Jiangnan region, which saw rapid economic growth compared to other areas since the Song Dynasty. Such plentiful research is gradually expanding into a discourse on examining the meaning of economic development and transformation in the Jiangnan region during the Ming and Qing Dynasties. Yet on the other hand, there are efforts to look to the Jiangnan region during the Ming and Qing Dynasties to find the driving force for China’s rapid economic development today. 1 This shows that the significance of economic * This work was supported by the 2013 Research Fund of Myongji University. ** Professor, Department of History, Myongji University 1 Regarding the two different positions concerning the economic growth of the Jiangnan region during the Ming and Qing Dynasties, refer to Philip C.

  • What Is Hydraulic Engineering?
    What Is Hydraulic Engineering? James A. Liggett1 Abstract: This paper, written to mark ASCE’s 150th anniversary, traces the role of hydraulic engineering from early or mid-twentieth- century to the beginning of the twenty-first century. A half-century ago hydraulic engineering was central in building the economies of the United States and many other countries by designing small and large water works. That process entailed a concentrated effort in research that ranged from the minute details of fluid flow to a general study of economics and ecology. Gradually over the last half-century, hydraulic engineering has evolved from a focus on large construction projects to now include the role of conservation and preservation. Although the hydraulic engineer has traditionally had to interface with other disciplines, that aspect of the profession has taken on a new urgency and, fortunately, is supported by exciting new technological developments. He/she must acquire new skills, in addition to retaining and improving the traditional skills, and form close partnerships with such fields as ecology, economics, social science, and humanities.

  • Hydraulics Manual Glossary G - 3
    Glossary G - 1 GLOSSARY OF HIGHWAY-RELATED DRAINAGE TERMS (Reprinted from the 1999 edition of the American Association of State Highway and Transportation Officials Model Drainage Manual) G.1 Introduction This Glossary is divided into three parts: · Introduction, · Glossary, and · References. It is not intended that all the terms in this Glossary be rigorously accurate or complete. Realistically, this is impossible. Depending on the circumstance, a particular term may have several meanings; this can never change. The primary purpose of this Glossary is to define the terms found in the Highway Drainage Guidelines and Model Drainage Manual in a manner that makes them easier to interpret and understand. A lesser purpose is to provide a compendium of terms that will be useful for both the novice as well as the more experienced hydraulics engineer. This Glossary may also help those who are unfamiliar with highway drainage design to become more understanding and appreciative of this complex science as well as facilitate communication between the highway hydraulics engineer and others. Where readily available, the source of a definition has been referenced. For clarity or format purposes, cited definitions may have some additional verbiage contained in double brackets [ ]. Conversely, three “dots” (...) are used to indicate where some parts of a cited definition were eliminated. Also, as might be expected, different sources were found to use different hyphenation and terminology practices for the same words. Insignificant changes in this regard were made to some cited references and elsewhere to gain uniformity for the terms contained in this Glossary: as an example, “groundwater” vice “ground-water” or “ground water,” and “cross section area” vice “cross-sectional area.” Cited definitions were taken primarily from two sources: W.B.

  • 16-1 Attachment 3 Glossary of Terminology for Hydraulics & Scour
    Memo to Designers 16-1A • December 2017 LRFD SupersedesSupersedes MemoMemo toto DesignersDesigners 1-231-23 DatedDated OctoberOctober 20032003 Attachment 3 Glossary Of Terminology For Hydraulics & Scour Definitions (refer to AASHTO LRFD-BDS-CA Section 2.2) Common terminology has been defined below for easy reference. Abutment Scour Abutment scour is essentially a form of scour at a short contraction. Accordingly, scour is closely influenced by flow distribution through the short contraction and by turbulence generated and dispersed in the form of eddies and vortices, by flow entering the short contraction. Aggradation General and progressive buildup (long term) of the longitudinal profile of a channel bed due to sediment deposition. Backwater The increase in water surface elevation relative to its elevation occurring under natural channel and floodplain conditions. It is induced by a bridge or other structure that obstructs or constricts the free flow of water that occurs in a channel. Bank Protection: Engineering works for the purpose of protecting streambanks from erosion. Base Flood Discharge associated with the 100-year flood recurrence interval. Base floodplain Floodplain associated with the flood with a 100-year occurrence interval. Bedrock The solid rock exposed at the surface of the earth or overlain by soils and unconsolidated material. Bridge Waterway The cross-sectional area of a bridge opening available for flow, as measured below a specified stage and normal to the principal direction of flow. Bulking Increasing the water discharge to account for high concentrations of sediment in the flow. Channel Profile A plot of the stream channel elevations relative to distance separating them along the length of the channel that generally can be assumed as a channel gradient.
