Sediment Deposition from Debris Flow on a Gentle and Wide Slope
Motion of sediment grains in the deposition process from debris flow on a gentle and wide slope was examined. A model of the deposition was presented on the basis of an analysis of grain...

Debris Flow & Hyperconcentrated Flow: A UK Perspective
Debris-flow activity within the UK is largely confined to upland regions and certain coastal locations. Within the uplands, debris-flow and hyperconcentrated flood waters pose a local...

Differentiation of Debris-Flow and Flash-Flood Deposits: Implications for Paleoflood Investigations
Debris flows and flash floods are common geomorphic processes in the Colorado Rocky Mountain Front Range and foothills. Usually, debris flows and flash floods are associated with excess...

Structural and Non-Structural Debris-Flow Countermeasures
Debris-flow can potentially occur for almost any torrents whose gradient is steeper than a given critical value and the frequency at which the debris-flow occurs depends on geological...

Integrated Planning Analysis for an Aggregate Mine
Planning and design work of an aggregate mining facility within the Sutter Bypass, a key component of California's flood control system, is being performed by multidisciplinary team of...

2-D Vertical and 3-D Modelling of Mud Transport in Tidal Flows
Model predictions of a fully three-dimensional sediment transport model are presented for two tidal flow variation cases. A simplified two-dimensional form of the model is applied to demonstrate...

Three-Dimensional Numerical Modeling for Transport Studies
Modeling three-dimensional transport of salinity and sediments in estuarine flows requires that hydrodynamics be accurately modeled with sufficient precision to describe the advection...

Shifts in Solute Transport Direction Induced by Transient Flow
Traditionally, solute transport projections have focussed on the long-term, steady state conditions expected to prevail in a groundwater system. However, transient effects may often dominate...

Modeled Hydraulic and Salt Transport Patterns in the Sacramento-San Joaquin Delta
Modeled hydraulic and salt transport patterns in the Sacramento-San Joaquin Delta have been summarized as the basis for detailed environmental assessment of proposed water management projects...

Structure of Coastal Upwelling on a Sloping Bottom
A large eddy simulation of coastal upwelling on a sloping bottom is carried out. The structure of the upwelling consists of a persistent primary front, a temporary secondary front which...

Storm Water Regulations?Aircraft Deicer/Anti-icers Operations
In 1991, FAA has initiated a storm water program to assist airport operators in complying the EPA Storm Water NPDES regulations. The first FAA project, a survey, addresses present operational...

Flow Diversion in a Steep, Coarse-Bed Stream
A case study is presented of the hydraulic design of a diversion structure in a high velocity, coarse bed streamcourse. Mill Creek, a tributary to the Upper Jordan River in the southern...

Pipelines Crossing Highways and Railroads by Tunneling
When new pipeline construction requires the crossing of highways and railroads, a pipeline is generally installed in pipe or tunnel linear plate encasement which has been installed by...

Freight Movement in a Changing World and Changing Market Place
The main object of this paper revolves on the fact that for the foreseeable future, the bottom line of intermodal challenges for any North American container port is that business, trade,...

Developing an Air Transportation Hub?A Planning and Analysis Process and its Application in Taiwan, R.O.C.
The Ministry of Transportation and Communications of the Republic of China in Taiwan wanted to know whether it was feasible and desirable to develop an air transport hub at Chiang Kai-shek...

The Design and Development of A Road/Rail Power Unit
The road/rail power unit was designed and developed by Saskatchewan Highways and Transportation to provide low cost motive power on low-density disconnected rail lines. The power unit...

Transport Planning for Hong Kong's Future Port Requirements
Hong Kong is currently the world's busiest container port. It regained the number one position from Singapore in July 1992 following a huge rise in annual throughput of 29% over the previous...

The Rokko Island Line of the Kobe New Transit System
Because Rokko Island was planned to be a mini-city with all the typical urban functions, it was essential to provide a means of transportation connecting it with the existing urban center...

Innovations in the Development and Expansion of Intermodal Facilities
The intermodal industry is a dynamic one, with a long history which has undergone profound change since the introduction of containerization only 30 years ago. Today, change continues...

Transportation Management Systems?The Key to Efficiency
Federal, State, and local governments are under increasing pressure to balance their budgets and cut costs while at the same time respond to public demands for quality services. The current...
