Properties in Sensitivity Coefficients of Framed Structures
This paper presents a special relationship among sensitivity coefficients of static response, natural frequency and mode. The relationship is that the sum of sensitivity coefficients in...

Optimal Adaptive and Predictive Control System of Buildings by Neural Network and Fuzzy Theory
This paper describes an optimal adaptive and predictive control system and its digital simulations for a single-degree-of-freedom system subjected to earthquake loading. In this system,...

Transient Performance Model of Asphalt Pavement Deterioration and its Application to Repair Management
The Japanese Ministry of construction has conducted surveys of the pavement surface condition of national highways. This paper describes the evaluation of the performance of asphalt pavement...

Nekton Use of Salt Marshes of the Southeast Region of the United States
Published studies of nekton in salt marshes of the Southeast Region of the U.S. were reviewed to identify fish and decapod crustaceans associated with marsh-surface habitats, to describe...

Responsible Governmental Structures: Coastal Management in the United States, Great Britain, and Australia
Commentators studying the coastal management strategies adopted by various countries have frequently criticized the lack of centralized national authorities aimed specifically at coastal...

A Classification of the Coastal Dunes of Louisiana
The aeolian deposits of the barrier coastlines of Louisiana to the west of the active delta of the Mississippi have been studied intensively for almost 20 years. The dunes, dune terraces...

Preliminary Study on Impacts of Sea Level Rise and Response Strategies in Japan
This paper presents the outline of the study carried out by a Japanese committee on the impacts of and response options to the anticipated sea level rise and climate change induced by...

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 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 Physically Based Methodology for Regional Flood Frequency Analysis
The problem of flood frequency estimation in ungauged catchments is approached by using statistical procedures jointly with derived distribution techniques. The application of this methodology...

Muskingum Basin Reservoir Pool Frequency Analysis
The purpose of the study was to develop a consistent and defendable elevation frequency analysis of pool elevations for sixteen reservoirs within the basin. A significant level of interest...

Peak Frequency Curves for the Middle Rio Grande
To define peak flow frequency curves for ten sites in the highly controlled and regulated Middle Rio Grande, an approach which relates peak inflow and peak outflow from the reservoirs...

Additional Years of Record and Peak Discharge
The effect of additional years of stream gaging records is analyzed for stream gages in Nebraska. Frequency estimates are based on procedures outlined in Bulletin 17B, including skew coefficient...

A Unified Approach to Flood Frequency Analysis
Most stochastic hydrologic studies are based on statistical distributions that are pre-selected without giving consideration to the applicability of the distribution to a particular data...

A New Look at the Statistical Estimation of PMP
The statistical base of Hershfield's K_mvalue Method and its application for estimating Probable Maximum Precipitation (PMP) were reviewed. The mathematical...

Estimating Exceedance Probabilities of Extreme Floods
Estimates of the exceedance probabilities of extreme floods are needed for risk analysis of dams and nuclear energy facilities. A new approach using a joint probability distribution of...

Hydrologic Regionalization Using a Homogeneity Test
A framework is presented for a regionalization method with a region of influence (ROI) approach. The methodology explicitly incorporates a homogeneity test in the process of selecting...

Acidity and Chemistry of Arizona's Snowpacks
Acid snow, the frozen version of the acid rain phenomena, has been sampled in several western states, e.g., California, Nevada, Montana, and Oregon. Measurements of snowpack acidity in...

Well Response in a Leaky Aquifer and Computational Interpretation of Pumping Tests
An analytic solution is derived describing flow in a horizontal confined leaky aquifer of infinite extent around a fully penetrating well of negligible storage capacity. The differences...
