Beach Evolution and Protection
This paper investigate the evolution of beaches and the effect of different types of protection on this process. The cross-shore and longshore sediment transport, and the different approaches...
Wave Diffraction Patterns Behind Detached Breakwaters
This paper presents a theoretical model to examine the wave diffraction behind detached breakwaters subjected to regular oblique waves. The method of solution is an eigenfunction expansion...
A Mathematical Model for Predicting the Motion of Polluting Surface Plumes Due to Drift Currents
The paper analyzes the problem of displacement from the offshore to the nearshore of a polluting surface plume, subject to advection generated by wind-waves and wind-currents. After a...
The Morphology of the Anglian Coast
The morphology of the Anglian coast consists of three Integrated Scale Coastal Evolution (ISCE) units. A bay, marked by the 10m bathymetric contour, extends from Flamborough in the north...
Morphology of the Southern North Sea Coast from Cape Blanc-Nez (F) to Den Helder (NL)
The southeastern North Sea coast of France, Belgium and the Netherlands (up to Den Helder) is characterized by coastal dunes, sandy beaches and a shallow, gently shoreface. In the Delta...
Coastal Morphological Modeling for the Southern North Sea
The paper gives a inventory of mathematical model concepts for coastal morphological applications, from sophisticated short-term process models based on first physical principles, via...
Long Term Wave Statistics
Long term wave statistics are needed for many applications in coastal engineering and oceanography in the southern North Sea. Three sources of wave data are available: visual observations,...
Modeling Beach Erosion and Shore Evolution
The objectives of this paper are to review some hydraulic modelling techniques for the evaluation of beach erosion and shoreline evolution due to wave and current action. Both numerical...
Study on Littoral Protection by Sand-Filled Tube
This study focuses on a new, excellent construction method which excels in both the environmental and scenic aspects. It enables the construction of coastal structures such as jetty, detached...
A Study on Fishing Port Structures in Harmony with Fishery Environment
We have reported on the concept of environmentally productive fishing port structures along the coastline of Japan ('91 LONGBEACH). In this paper we present a field model experiment on...
The Planning and Design of Multipurpose Artificial Barrier Reefs
Multipurpose artificial barrier reef is proposed for the enhancement of fisheries as part of the purpose of entire system of structures in Japan. As part of our planning efforts we are...
Development of the Double Cylinder Caisson Breakwater
A double cylinder caisson breakwater was recently developed to create a calm sea area in deep and high wave open sea areas. In order to confirm some subjects on design method and construction...
Quantitative Assessment of Marine Traffic Environment by Using the Maneuvering Space Concept
In a coastal zone, it frequently becomes important to assess the influence of the constructions upon the marine traffic environment. Marine traffic is a man-machine system, and so not...
Before-After Evaluation of FTMS Effectiveness
This paper demonstrated the possibilities for conducting before-after evaluation of a new freeway traffic management system (FTMS) using only data from the inductive loop detectors. Using...
Migration to Traffic Adaptive Control?A Case Study
Many of the urban traffic control systems currently in operation around the world are based on first generation control technology, and for various reasons, they are now in need of renewal....
Estimation of Queue Lengths in Urban Road Networks
In this paper we present a new scheme for the surveillance of traffic state on a link of an urban road network. It is shown that measurements of traffic counts and speed values from a...
Travel Time Data Fusion in Advance
The ADVANCE project in the Chicago metropolitan area is one of several ATIS operational tests currently underway in the USA and abroad. Fusion of equipped vehicle (probes) travel time...
Filtering and Prediction on Freeways Using Markov Models
A Markov compartment model of freeway traffic flow is presented and used to derive a Kalman Filter which tracks a freeway section's density, broken down by destination. The filter is then...
Freeway Control Systems for Using Section-Related Traffic Variable Detection
Traffic control systems for freeways are described which use section-related traffic variable measurement techniques. For deriving section-related variables feature sequence of a vehicle...
Using VRC Data for Incident Detection
Most existing incident detection algorithms use inductive loops, a relatively old sensor technology that obtains data at specific points along the roadway. This paper discusses the use...
