Influence of River Mouth Migrations on the Caucasian Black Sea Coast Development
When studying modern coastal and river-issue processes and comparing last century and modern maps some regularities were revealed. River arms, which are upstream the longitudinal sediment...

State-of-the-Art and Dynamic of Some Beaches of the Bulgarian Black Sea Coast
The considerable decrease of the solid flow off in the sea coastal zone and the intensification of the abrasion impact on the shore determined the increase of the coastal protection activity...

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...

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...

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...

Overview of the FAST-TRAC IVHS Program
A major new IVHS initiative, called FAST-TRAC, is taking place in Oakland County, Michigan. It originated as a bottom-up strategy for solving mobility and highway safety problems in this...

Optimal Strategy Within a Traffic Control Center
This paper describes part of a new Central Traffic Control System (CTCS), implemented in several sites in Europe, and recently in Haifa, Israel. The CTCS effected in Haifa contains enhanced...

A Neural Network Model for Data Fusion in ADVANCE
As current state of the art technology on smart cars and Smart Highways is processing, applications of advanced technologies in transportation engineering are becoming more and more important....

Modeling Route Guidance Systems Using the Integration Model
In-vehicle Route Guidance Systems (RGS) have been proposed as a potentially cost-effective means of alleviating the impact of traffic congestion in urban areas. This paper describes means...

Simulation of the Dynamic Traffic Flow on Urban Road Network
Methods of performing dynamic traffic assignment are needed to simulate traffic conditions on urban highways during peak periods of congestion. In this paper, the route choice behavior...

Detection of Incidents and Traffic Disturbances in Freeways
This research aims to develop methods for detecting incidents and compression waves through simulation. The detection methods are based on a macroscopic traffic flow model that focuses...

Temporal Variation of Precipitation Trend at Seoul, Korea, 1771-1991
This paper describes temporal variation of annual precipitation trend from 1771 to 1991 at Seoul, Korea. Analysis of the series shows no distinct trend over years. A linear trend would...

Smith's Infiltration Equation and Flooding Infiltrometers
Smith's infiltration equation was developed by examining the output from runs of a physically-based numerical model of one-dimensional infiltration. The model simulated application of...

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...

Effects of Climate Change on Drought Risks in the Apalachicola, Chattahoochee, and Flint River Basin
Possible effects of climate change on the Apalachicola-Chattahoochee-Flint (ACF) River basin is simulated with a computer model. Model inputs are monthly temperature and precipitation...

Combining Orographic Precipitation and Runoff Models for Improving Reservoir Operations
This paper reports on a study being conducted by the Bureau of Reclamation whose end objectives are improved quantitative precipitation forecast (QPF) for use in hydrologic runoff models...

Hydrology of Wetland Treatment Systems in East Orange County, Florida
Wetlands are increasingly being used as final treatment systems for industrial and domestic wastewater effluent discharges and stormwater runoff discharges. Hydrological monitoring and...

Ecohydrological Processes in Almost Flat Wetlands
In spite of their modest relief almost flat wetlands are able to maintain definite topographically driven groundwater flow systems. Large seepage areas create ecohydrological gradients...

Linking Hydrologic and Hydraulic Routing Models in Low Relief Basins of South Florida
Combined use of hydrologic and hydraulic routing models to analyze the rainfall-runoff processes during a storm event is a common practice. In this approach, a hydrologic model is employed...

Back to the Unit Hydrograph Method
In this paper, the basic single area unit hydrograph model is shown to represent a highly complex, rational, link-node model which includes (i) variable effective rainfall distributions...
