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...

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....

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...

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...

Mountainous Precipitation Estimation Using Multivariate Statistical Analysis and Geographic Information Systems
Using rotated principal component analysis (PCA), unique, orthogonal spatial patterns of daily and monthly precipitation on a well-instrumented, mountainous watershed in Idaho (USA) were...

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...

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...

Estimation and Regionalization Procedures of Nash's Instantaneous Unit Hydrograph
A 'total fit' method is suggested for computing Nash's instantaneous unit hydrograph (IUH) which minimizes the errors of all ordinates between the observed and generated hydrographs. Previous...

Two-Dimensional Flood Hazard Simulation on Alluvial Fans
The incentive for flood hazard delineation on alluvial fans is development. Drainage plans and flood mitigation design require prediction of flow hydraulics for a range of hyperconcentrated...

Hydraulic Modeling of Alluvial Plains (Slopes) and Alluvial Fans Using DAMBRK
The design of hydraulic structures such as bridges on distributary flow areas and alluvial fans require methods that can adequately determine discharges at the structures. Flow conditions...

Establishment of a Habitat Monitoring Program to Assess Potential Impacts of Diversion of POTW Effluent
As part of the permitting process for a gas-fired power plant, the environmental impacts of diverting POTW effluent from the receiving water for cooling tower makeup was investigated....

Stochastic Modeling for Drought Analysis Using Thomas-Fiering Lognormal Three Parameter Model
Three variations of Thomas-Fiering log normal 3-parameter(TFLN3) model are fitted to the unregulated south-west monsoon-dependent monthly streamflows measured at Krishnarajasagara (KRS)...

Variance Estimation of Extreme Flows
The inclusion of historic flood data with gage record data has been shown to reduce the uncertainty in flow estimates. Using numerical integration to quantify that uncertainty is less...
