An Investigation into Causes of Bank Caving
A series of investigations into bank caving along the Ohio River are described. These investigations include a study of the distribution of precipitation in the study region, derivation...
Stormwater Management in Virginia
In the 1986 budget bill, the Virginia General Assembly directed the Virginia Department of Conservation and Natural Resources, Division of Soil and Water Conservation, to conduct a review...
Computing in Civil Engineering
Microcomputers to Supercomputers
This book contains papers presented at the Fifth Conference on Computing in Civil Engineering. Computer applications in specific disciplines are covered. These include construction engineering...
Skytrain Crosses the River
The cable stayed bridge that will carry Vancouver's light rail line across the Fraser River is the world's longest such bridge built solely for mass transit....
Rehabbing the Underground Railroad
The Park Ave. Railroad Tunnel brings three commuter rail lines into New York City's Grand Central Station. The four tracks occupy three tubes from 97th St. to 57th St., where...
Japan Tunnels under the Ocean
The 54 km Seikan Tunnel, the longest undersea railroad in the world, opened in March. The tunnel, which connects Japan's two largest islands, Hakkaido and Honshu, is part...
Modeling Pesticide Metabolite Transport with Gleams
The GLEAMS model (Groundwater Loading Effects of Agricultural Management Systems) was modified to simulate the generation and degradation of pesticide metabolites. Translocation of the...
Simulation of Contaminant Transport Using NMOL Technique
In this paper, a new numerical method, called Numerical Method of Lines (NMOL), is used to solve initial-boundary value problems for solute transport in soils. The simulation results are...
Random Characteristics of Sediment-Laden Flows and the Techniques of Effective Sediment Exclusion on Dujiangyan Irrigation Project in China
The irrigation system is over 2,200 years old and discharges water at a rate of 340-740 m3/s from the Minjiang River. The average slope of the river...
Drainage Through Segara Anakan
The Lower Citanduy Irrigation Project in Central Java, Indonesia, drains through the estuary called Segara Anakan. Due to sediment accretion, the lagoon is filling. With erosion problems,...
Platte River Irrigation Development: Hydrologic Myths
Several proposed municipal and irrigation developments in Wyoming, Colorado and Nebraska could impact flows along the Platte River in central Nebraska. Opposition to these projects is...
Stable and Environmental Channel Design
The Wildcat and San Pablo Creeks Flood Control Project is located in Richmond, California. Both streams flow through a highly urbanized area, periodically overflowing their banks and causing...
Stable Channels with Loose Boundary
Recently, G. Parker suggested that the lateral transport of downstream momentum due to Reynolds stresses should be included in the momentum balance used to calculate the boundary shear...
Pinto Wash Alluvial Fan Litigation
This paper presents a case history involving flood/damage litigation brought by a downstream farmer against an upstream farmer and a local public irrigation district. The case combined...
Applications of GSTARS Model
GSTARS is a Generalized Stream Tube model for Alluvial River Simulation. Depending on an engineer's need, GSTARS can be used as a fixed boundary as well as a movable boundary...
Two-Dimensional Numerical Modeling for Long-Term Sedimentation
Numerical modeling of long-term sedimentation processes in multi-dimensional models is computationally intensive and thus often uneconomical. A statistical superposition technique has...
Mathematical Modeling of Compound Channel with High Sediment Concentration
The mathematical model for erodible channels, FLUVIAL-12, has been extended to simulate the fluvial processes in the lower reach of the Yellow River in China. Fluvial processes in the...
Geotechnical and Hydraulic Stability Numbers for Channel Rehabilitation: Part I, the Approach
A model of incised channel evolution was developed to integrate the geotechnical and hydraulic factors that are involved in channel rehabilitation. Bank stability is attained when the...
Stratigraphy of Alluvial Fan Flood Deposits
The purpose of this paper is to describe an engineering geologic technique for assessing the frequency and magnitude of sedimentation events on alluvial fans. The technique is based on...
Design Depths and Velocities on Alluvial Fans
Under Federal Emergency Management Agency (FEMA) guidelines, flood depths and velocities on alluvial fans are determined by considering the probability of a given point on the alluvial...
