Proportioning Reinforcement for Buried Concrete Pipe
The proportioning of reinforcement between inner and outer cages that is specified in ASTM Standard Specification C76 for concrete pipe in sewer and culvert applications is examined in...
Teaching Open Channel Design with Programmable Pocket Calculators
The goal of the basic open channel flow course is to present the theory of steady flow of water in open channels and some channel design practice. This paper presents the evolution of...
Comparing Flood Stage-Discharge Data?Be Careful!
A long term stage-discharge record is extremely valuable data. However, simplified applications of long term records to draw sweeping conclusions about man's effects should be avoided,...
Prediction of Shoaling in Estuarial Channels: A Microcomputer Application
Shoaling rates at three predominant areas of sedimentation in the Hooghly River estuary, India, have been predicted using a sediment transport model run on an IBM compatible microcomputer....
Computer-Based Design of River Bank Protection
A study using the FLUVIAL-11 computer model was made for the Rillito River in order to determine the design configuration for the bank protection which must contain the design flood and...
Eight Open Channel Flow Programs for the Apple IIe Microcomputer
The purpose of this paper is to present eight programs in hydraulics and hydrology suitable for running on the Apple IIe and Apple IIc microcomputers. The programs are: Flood 1, Flood...
Water Surface Profiles in Compound Channels
The paper explores the use of the proposed compound channel Froude number in problems of water surface profile computation. It can be used not only to determine critical depth and to identify...
Boundary Shear Stress in a Meandering Channel
Longitudinal and transverse velocity, bed shear, and water surface elevation were studied in a fixed-bed, meandering, laboratory channel with naturally varying, non-prismatic cross sectional...
Computation of Gradually-Varied Flows in Channel Networks
For computing steady-state, gradually-varied flows, a new algorithm is presented which allows solution of the entire channel system simultaneously, and unlike other available methods,...
Analyses of Sediment Transport Data by Microcomputer Software
The MINITAB statistical software project has been popularly used on mainframe computers since 1972. In June 1984, a subset of the program was made available for the IBM-PC microcomputer;...
Explicit Hydraulic Modeling of Sedimentation Transients in Alluvial Channels
An explicit finite difference numerical scheme is used in this study to model sediment transients in alluvial channels. The governing equations are momentum equation and continuity equation...
A Microcomputer Program for River Sedimentation
Erosion and deposition of sediment in rivers causes numerous problems. In order to describe this process, both the hydraulic properties of the river and the mechanics of sediment transport...
Flood Routing Through Rock Dumps in Natural Channels
The paper deals with flow through rockfill to analyze the problem of flood routing through large masses of waste rock from mining operations dumped in natural channels. Rock dumps in ephemerous...
Explicit Finite Element Model for Long Water Waves
An explicit finite element model for free-surface flow is presented. The model is capable of simulating long waves of various orders of approximation in one and two space dimensions. The...
A Unique Communication System for Aerial Ropeways
The basic principles of operation of a Double Reversible Aerial Tramway are introduced. A brief note is given explaining a safety circuit or survey current used on the haul rope, since...
The Effect of Connection Flexibility on Steel Members and Frame Stability
With the advent of Load and Resistance Factor Design (LRFD) and the many existing moment-rotation curves for connections, the use of actual connection flexibility in the design process...
Type C Fly Ash and Clay Stabilization
Because the soils onsite have a high swell potential, a 37 foot high retaining wall was designed with counterforts and was supported by pier foundations to limestone. In order to reduce...
Tensile Fracture and Fatigue of Cement Stabilized Soil
Portland cement stabilized soil is widely used as a base material for roads, airfields, and similar structures. Cracking in this material is studied using fracture mechanics concepts....
Design and Performance of Shiroro Rockfill Dam
Shiroro Dam, constructed across the Kaduna River in Nigeria, is a rockfill dam with reinforced concrete facing. The dam was completed in late 1983, and reservoir impounding started in...
Seismic Design of Concrete Faced Rockfill Dams
The results of analytical studies of the stability of the slopes of concrete-faced rockfill dams under different levels of earthquake shaking are presented and used to propose desirable...
