Sandy Accumultive Forms Within the Black Sea Coastal Zone
Most of the sandy accumulative forms of the Black Sea are within Ukraine territory. There are various types of these forms differing in morphology, dynamics, source of material, interaction...
Wave Diffraction Patterns Behind Detached Breakwaters
This paper presents a theoretical model to examine the wave diffraction behind detached breakwaters subjected to regular oblique waves. The method of solution is an eigenfunction expansion...
Long Term Water Level Observations and Variations
Numerous tide gouges have been recording data along the coastlines of the southern North Sea for more than a century, at Amsterdam even since 1700. Every tide gauge locality has its own...
Long Term Wave Statistics
Long term wave statistics are needed for many applications in coastal engineering and oceanography in the southern North Sea. Three sources of wave data are available: visual observations,...
Louisiana Cheniers: Clues to Mississippi Delta History
The cheniers of southern Louisiana have map differences, deeding differences, and granulometric differences that distinguish them from swash-built beach ridges and from dune ridges. Instead,...
Classification of Coastal Zone by Multi-Variate Analysis
Coastal zone is characterized by various factors such as natural and socio-economic conditions. The present paper proposes a method to classify the coastal zone into some identical groups...
Image Measurement Systems for Traffic Analysis?Specifications, Survey, and Limits
This presentation is concerned with systems for extraction of road traffic information from visual images. The extracted information ranges from macro-scale, cumulative traffic parameters...
Rain Gage Network Size for Automated Flood Warning Systems
A methodology is presented that establishes a rational framework for estimating the optimum rain gage network size for flash flood warning systems based on network performance and economic...
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...
A Statistical Climate Inversion Scheme and its Application in Hydrologic Impact Assessment Studies Associated with Global Climate Variability
The use of deterministic atmospheric, general circulation models (GCM's) to understand potential global climate change under doubled CO2 forcing...
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...
Hydrologic Modelling of Extreme Flood on Small Mountainous Watersheds
Statistical and deterministic methods for extreme flood estimation were applied to Swiss alpine catchments to assess the application limits of each approach. Comparative results produced...
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...
Statistical Analysis of Extreme Hydrological Droughts
The study examined several works about extreme droughts for their validity with different parameters by the statistical experimental method. The results showed that the analytical method...
Can Statistical Methods Help to Forecast Drought?
Relationships have been developed between rainfall in eastern Australia and both southern oscillation (SO) and sea surface temperatures (SSTs), and between rainfall in Ghana, West Africa...
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)...
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...
Incorporating GIS Technology in Standard Flood Hydrology Applications
The potential for application of Geographic Information Systems (GIS) to hydrologic analyses has received increasing attention in recent years. Published literature on hydrologic applications...
A Comparison of L-Moments with Method of Moments
A comparison of the Conventional Moments Method (CMM) with the L-Moments Method (LMM) for selecting a distribution is made. Five distributions GEV (Generalized Extreme Value), LNO (Lognormal),...
A Probabilistic Approach to Estimate Design Parameters for Flood Control Projects
The purpose of this paper is to provide engineering consultants with an improved method to estimate design parameters for various return periods in rural areas. The proposed method combines...
