The Use of Multibody Software in the Wheel/Rail Contact as Applied to Very High Speed Tests
How strange may it be, the behaviour of railway vehicles depend on contact forces developing between wheels and rails inside patches of no more than 1 cm2....
Coast Dynamics and Coast-Protective Measures on the Crimean Black Sea Coast
The main data on hydro- and lithodynamics of the Crimean Black Sea coast are presented. The principal coast-protecting measures are described as used on various coast sections. The construction...
The Specific Features of Modern Dynamics and Coast Structure of the Black Sea Within Romania
The Romanian Black Sea coasts are studied inadequately in comparison with Ukrainian, Russian, Georgian, and Bulgarian coasts. Abundant data have been collected in the Danube delta. The...
About Some Dynamic Conditions of the Beach Sedimentary Strata Formation on the Bulgarian Sandy Coast of the Black Sea
Based on detailed studying of the beach sedimentary sequence composition in sections of perpendicular trenches in the western (Bulgarian) coast of the Black sea and comparison with results...
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...
Implications of Environmental Dynamics for Sustainable Environment and Resources Management Futures in the Niger Delta
The paper examines the implications of environmental dynamics for environmental sustainability and resources management futures. The paper first discusses the concept and characteristics...
A Dynamic Real-Time Incident Detection System for Urban Arterials?System Architecture and Preliminary Results
This study presents a system which is capable of detecting incidents in real-time and adjusting itself to traffic dynamics through the embedded learning mechanism. The entire system consists...
Scaling Laws of Gravity Driven Fingering During Organic Liquid Infiltration
Wetting front instability can occur during vertical infiltration of a liquid into porous media, particularly when a fine soil layer is overlying a coarse layer. The result of this instability...
Dynamic Perspective on the Capillary Barrier Effect at the Interface of an Upper Fine Layer with a Lower Coarse Layer
The theoretical principles behind the determination of infiltration rate into a coarse layer overlain by a tight layer are reviewed. As a descending unsaturated wetting front hits the...
A Review of Surface-Groundwater Interaction Models
Surface-water and groundwater systems are in continuous dynamic interaction. Processes such as infiltration from surface waters and precipitation, the discharge of groundwater to surface...
Real-Time Dynamic Flood Routing with NWS FLDWAV Model Using Kalman Filter Updating
Dynamic flood routing model based on the four-point implicit finite-difference solution of the complete one-dimensional Saint-Venant equations of unsteady flow are inherently deterministic....
Transfer Function Modeling of Evapotranspiration
The correct estimation of evapotranspiration is a fundamental step in planning, design and operation of most water resources projects. The dependence on various climatological parameters...
Assessment Procedures for Lahars, Mudflows, Debris Flows and Debris Torrents
Unique hydraulic and rheologic characteristics of lahars, mudflows, debris flows and debris torrents require specialized assessment procedures. This paper discusses a fourteen element...
A Model for Low-Drag Landslides
Field observations and experimental records indicate that the primary mode of motion of many large landslides is that of sliding rather than flowing. Most of the shear during sliding is...
Incipient Motion in Gravel-Bed Rivers
Incipient motion processes are reviewed for bed material in gravel-bed rivers. Prediction difficulties are identified. Research results are reported for field and flume studies to investigate...
Criticality of Density Intrusions
Previous analyses of density intrusions indicates that a steady interface cannot be maintained if the front propagates at a speed greater than that of long interfacial waves. Supercritical...
A Model for Vertical Transport at a Sheared Density Interface
A physically based model for vertical mixing and transport at a sheared density interface is presented, based on high-resolution measurements from laboratory experiments. It is found that...
Drag Characteristics of Coarse Sediment in Clay Suspensions
Drag characteristics of spherical particles in clay suspensions, such as coarse sediment in hyperconcentrated flows, has been analyzed by using a limited data available in the literature....
Hydraulic Modeling of High Unit Discharge Energy Dissipators
The incorporation of an efficient and economical energy dissipation device is critical with respect to the safe operation of a high unit discharge spillway. The development and design...
