      <title>ON THE LIMITATION OF EROSION OF THE CANAL AND RIVER BANKS BY INLAND WATERWAYS VESSELS</title>
      <link>https://trid.trb.org/View/445899</link>
      <description><![CDATA[This paper describes model tests and full scale measurements to recommend improved design of canal vessels to reduce the energy transfer between canal craft and the bottom and banks of canals and rivers, particularly the narrow canals of Britain.  The nature of the environmental problem and the application to other craft in other waterways is discussed.]]></description>

      <title>IN SEARCH OF LOW WASH HULL FORMS</title>
      <link>https://trid.trb.org/View/439257</link>
      <description><![CDATA[Damage to river and canal banks caused by passing boats is a matter of concern for several inland waterways authorities and in the past few years much research work has been done in an attempt to reduce the problem.  The first part of this article reports on a major study carried out in 1986 for the Norfolk Broads Authority by Hydraulics Research Ltd of Wallingford, U.K.  The report showed that a general reduction in speed was the simplest way to reduce damage from boat wash, since a one mile per hour speed reduction had more impact on wash than the variability between the best and worst hull at a given speed.  The second half of the article reviews the work carried out by BMT Fluid Mechanics Ltd., Teddington, U.K., to produce a boat hull form which inherently produces less wash at a given speed, while retaining the length to beam ratios which commercial reality demands for this kind of craft.]]></description>

      <title>LOW WASH DISPLACEMENT CRAFT</title>
      <link>https://trid.trb.org/View/403993</link>
      <description><![CDATA[The Czerniak Displacement Ducted Vessel, which this article describes, is designed to swallow its own bow wave, divert it through channels under the hull, and discharge it past the rudders from a tunnel at the stern.  On a trial on the wide Trent Canal, the 10-meter-long PROTO 3, displacing 8 tons and traveling at 7-1/2 knots, made no bow wave. The water from the stern, diverging eventually, made a wave that hardly moved the rushes along the bank and did not disturb moored boats.]]></description>

      <title>THE QUEST FOR LOW WASH ON THE CANALS</title>
      <link>https://trid.trb.org/View/403231</link>
      <description><![CDATA[The inland waterways of England and Wales include numerous canals that are narrow and shallow and have a trapezoidal cross section. To limit bank erosion, a strict speed limit of four statute miles per hour is applied. In the narrowest places, this may be too high and it is up to the individual steerer to limit the size of the damaging wash. The British Waterway Board (BWB) is therefore sponsoring studies to develop an improved hull form with low wash. The status of these studies is reviewed and the mechanism of bank erosion is explained.]]></description>

      <title>RESPONDING TO CHANGES IN SEA LEVEL: ENGINEERING IMPLICATIONS</title>
      <link>https://trid.trb.org/View/398791</link>
      <description><![CDATA[This book considers the engineering implications of relative mean sea level change. Topics covered include: recent sea level trends; projections of continuing relative change; shoreline response to changing sea level and consequences for coastal development and uses; methods for protecting structures from erosion and flooding; and the need for new mitigation technologies. A major conclusion of the book is that "the risk of accelerated mean sea level rise is sufficiently established to warrant consideration in the planning and design of coastline facilities."]]></description>

      <title>THE INFLUENCE OF NAVIGATION ON WATER QUALITY AND CONTAMINATION OF ALLUVIAL DEPOSITS IN RIVER CHANNELS</title>
      <link>https://trid.trb.org/View/403037</link>
      <description><![CDATA[The authors discuss: river channel water pollution caused by river vessels and industrial sewage and chemical substances; oil contamination and oil films on water surfaces that hinder the activities of phytoplankton; and the influence of shipping on bank degradation by wave motion. They then take up problems related to the dumping into the river of soil dredged from the river bed; describing procedures for estimating the turbidity area and the zone boundary of maximum permissible concentration of suspended soil particles. The influence of dredging upon river ecology is next examined. The final subject concerns the long- and short-term effects of extracting sandy gravel from the bottom upon turbidity and the habitat conditions of hydrobiospecies.]]></description>

      <title>THE STABILITY OF BOTTOM AND BANKS SUBJECTED TO THE VELOCITIES IN THE PROPELLER JET BEHIND SHIPS</title>
      <link>https://trid.trb.org/View/394671</link>
      <description><![CDATA[A method is presented to predict the approximate velocities behind a propeller of sailing and maneuvering ships. The influences of the rudder, the rudder angle and an eventual nozzle are taken into account. Relations are also developed between the current velocities and the stability of bottom and banks consisting of non-cohesive material. With the results obtained, it is possible to determine whether or not erosion will occur, to calculate the dimensions of the scour hole or to determine the required dimensions for protection materials.]]></description>

      <title>THE POSSIBLE IMPACT OF VESSEL WAKES ON BANK EROSION</title>
      <link>https://trid.trb.org/View/150855</link>
      <description><![CDATA[A summary is given of the knowledge available on vessel-generated wake, and the possible impact of this vessel wake on bank erosion. A literature survey was conducted to identify the various causes of bank erosion along waterways. A summary of the various natural effects and possible vessel effects is provided. Recession of waterway banks involves a large number of effects. The physical and chemical nature of the channel's water, the materials forming the bank, and the groundwater may increase the soil's erodibility by formerly noneroding water currents, wind waves, or vessel wakes. No computational methods exist for linking a vessel with a chosen hull shape, traveling at a chosen speed in a channel of chosen depth and chosen cross-sectional area and shape with banks of chosen height and materials, to a predicted occurrence of erosion.]]></description>

      <title>FILTER FABRICS CAN CUT COSTS OF RIVER-BANK AND SHORE-PROTECTION STRUCTURES</title>
      <link>https://trid.trb.org/View/53177</link>
      <description><![CDATA[Over the past decade, plastic filter fabrics have seen growing use in shore-protection structures, river-bank protection schemes, and other areas where water comes into direct contact with soil.  In a typical application described, the filter fabric is laid directly on top of the soil to be protected, and rip rap, concrete blocks, or some other form of armor protection laid on top.  The fabric prevents water from gouging out the soil from behind the armor, a process that would result in the inward collapse of the embankment-protection structure.  A number of case histories explaining where and why the fabric was used and how well it has performed is presented.]]></description>
