Migration to Traffic Adaptive Control?A Case Study
Many of the urban traffic control systems currently in operation around the world are based on first generation control technology, and for various reasons, they are now in need of renewal....
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...
Change of Estuarine Processes Due to Sea Level Rise and Navigation Channel Improvement
To investigate the relationship between the improvement of navigation channels and the change of estuarine environment under various sea level rise scenarios, numerical study was performed...
Design Hydrographs in Coastal Wetland Watersheds
The use of synthetic unit-hydrographs for hydraulic design in ungaged watersheds has been an accepted practice for over 50 years. In southeastern U.S. coastal regions, which contain extremely...
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...
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...
Practical Experience in the Probabilistic Based Management of Large Water Resources Systems
Probabilistic tools to assist with the management of large water resource systems in South Africa were developed and applied during the last decade. Acceptance today is not only due to...
Stochastic Modelling of Mean Monthly Runoffs for Coruh Basin, Turkey
Stochastic models of monthly runoffs for Coruh basin, Turkey are presented. Coruh basin is located on the northeast part of Anatolia near Black Sea. Three gauging stations which have about...
Large Flood Plains Modeling by a Cell Scheme: Application to the Pantanal of Mato Grosso
The computational modeling of large flood plains presents difficulties related to the mathematical approach of the phenomenon and also to the discretization of the area under study. In...
Global Search Technique to Calibrate Rainfall Runoff Models
The calibration of rainfall-runoff models in hydrology has not yet reached a satisfactory solution, using either manual or automatic procedures. This paper introduces a simple conceptual...
A New Look at the Potential of Hygroscopic Seeding in Summertime Convective Clouds
Hygroscopic seeding was conducted in the sixties and early seventies in the USA, but since then, most cloud seeding efforts have used glaciogenic seeding materials, usually silver iodide...
Effect of Agricultural Drainage on Water Quality in the Southeastern Coastal Plain
This paper is designed to consolidate selected research and results from investigations of the impacts of agricultural drainage on water quality in North Carolina, South Carolina, and...
Watershed Erosion
Scientific agricultural planning requires knowledge of the relations between soil and water that cause soil loss, and of the procedure to reduce such losses on cropland. This paper presents...
Refined Modelling of Water Quality Constituents in a Semi-Enclosed Coastal Wetland Basin
Details are given of the refinements to a numerical model to improve the representation of the advective transport of water quality constituents. The higher order accurate scheme adopted...
Pier Scour Equations Used in China
This report describes the equations used in the People's Republic of China for estimating scour depth at bridge structures. The equations were worked out from model and field data at the...
Stratification Models Sensitivity to Solar Radiation Data
A one-dimensional water quality model (WESTEX model) for simulation of thermal stratification is used to test the performance of such models related to hydrometeorological input data....
Methods for Prediction of Maximum Scour at Coastal Structures
The most common coast scour-related problems are toe scour at rubble mound structures and vertical seawalls, and scour at the base of piles and horizontal pipelines. Existing scour prediction...
A New Type of Concrete Trapezoid Dam
A new type of 128.0 m height concrete trapezoid dam (t-d) has been built for the Wunana Town Hydroelectric Power Station (WTHPS). The paper presents its optimum section design, several...
Chinese Standard for Concrete-Filled Tube Columns
