Japan's Port Management and The United States' Port Management
Management systems vary between ports, as well as between countries. Some systems are nationally centralized and others are relatively independent from government control. Between Japan...
A Study of Political Decision Method for Remote Island's Environmental Management?Patterns of Remote Islands and a Political Goal
Remote islands are handicapped in their incomes and living conditions, because they are surrounded by oceans, the area is rather small, and also they are far from economic and cultural...
Strategic Updating of Autonomous Route Guidance Systems for Air Quality Management
The work in this paper stems from applied research which is implemented as part of the QUARET project. QUARET is a major initiative by four European Community cities. Athens, Birmingham,...
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...
Modified Horton Models for Steady Rainfall
When the rainfall rate is less than the initial infiltration rate, direct application of the well-known Horton equation underestimates the total volume of water infiltrating the soil until...
Robust Method to Generate Multiple Unit Hydrographs
When performing a rainfall runoff study, it is sometimes necessary to change the duration of a given unit hydrograph. The instantaneous unit hydrograph (IUH) provides an ideal tool to...
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...
Flood Assessment at a Low-Level Radioactive Waste Site in Southern Nevada
Flood hazard analysis on alluvial fans using Federal Emergency Management Agency (FEMA) methodology is not limited to the FEMA Alluvial Fan Methodology (AFM). Other FEMA-accepted methods...
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...
Peaks Over Threshold Model for Seasonal Flood Variations
The peaks over threshold (POT) series model has been used in hydrology to analyse extreme phenomena such as floods or precipitation amounts exceeding a certain threshold level. The results...
Robust Estimators in Hydrologic Frequency Analysis
This paper applies a specific robust estimation procedure known as 'trimming' in flood frequency analysis. The trimming technique consists in censoring the series of recorded floods by...
The Method of Derived Distributions Applied to Peak Flows
Random variables which are functionally related have their probability distributions also related in a prescribed manner. Thus, in theory, the probability distribution of peak discharge...
A Revised Snowstorm Maximization Method for Canadian Boreal Regions
A proposed refinement in the development of design snowpacks for use in the derivation of probable maximum floods (PMF) estimates in the Canadian Boreal is presented. Shortcomings in the...
Kinematic Mixing in Stratified Aquifers
The mixing process in heterogeneous aquifers is presented as the bending and stretching of material lines. A linear mixing efficiency is defined in terms of the mean values of a unit length...
Unit Hydrograph Estimation Procedures Using Orthogonal Functions
All unit hydrograph estimation procedures based on orthogonal functions are reviewed in this paper. A more physically based orthogonal function (a gamma function) for unit hydrograph estimation...
An Integrated Software System for 3DFEMWATER: A 3D Grid Generator, A Graphical Post-Processor, and Additional Analysis Tools
An integrated software system for 3DFEMWATER has been developed to improve the groundwater flow modeling process. The system generates finite-element grids, graphically portrays simulation...
Modeling Two-Dimensional Subsurface Flow, Fate and Transport of Microbes and Chemicals
A two-dimensional model to simulate the subsurface flow, microbial growth-degradation, and transport and biodegradation of chemicals in groundwater environments (2DFATMIC) is developed....
A Two-Dimensional Flow and Hydrogeochemical Transport Model
A two-dimensional flow and hydrogeochemical transport model is designed for estimating the movement and attenuation of chemicals after they are released into subsurface systems. This model...
Adapting BMPs to California Hydrology and Climatology
The State of California has the most diverse hydrology and climatology in the United States. It boasts the highest and lowest elevations in the continental U.S. and annual rainfall varies...
Impact of Digital Elevation Model Grid Size on Extracted Drainage Parameters
The dependence of extracted drainage network properties on the spatial resolution of DEMs is investigated for a study basin. A series of raster DEMs of increasing cell size is generated...
