Pipeline Rehabilitation with Polyolefin Pipe
This paper provides an introductory discussion on the rehabilitation of a deteriorated pipe structure by insertion renewal with continuous lengths of polyolefin pipe. This sliplining or...
Buried Pipeline Research Needs
A workshop was convened with representatives from universities, consulting engineering and research organizations, pipe and/or equipment manufacturers, constructors, users, and government...
Special Topics in Foundations
This book contains papers presented at a session related to various theoretical and experimental developments on foundation analysis, design and construction. The papers were written by...
Soil Properties Evaluation from Centrifugal Models and Field Performance
The performance of geotechnical projects is dependent upon the appropriateness of the design theory to the boundary conditions, and the characterization of the soil properties used in...
Evaluation of Infiltration Equations Used in Surface Irrigation
Computer simulations of an irrigation event were conducted using 6 full hydrodynamic models. All 6 models used the same surface flow equations and a different infiltration component. The...
Hydraulic Studies of Surface Drainage from Level Furrows
Field studies have been completed to quantify the surface drainage phenomenon from level furrows which were rapidly flooded and then drained from the inlet end of the furrow. The proportion...
Needed Social, Cultural and Design Changes to Successfully Manage Nigerian Surface Irrigated Projects
The aim of this paper is to illustrate the broad nature of problems associated with the faulty initial designs of water distribution network and irrigation methods and poor participartion...
Surface Water-Groundwater Relations for Open Channels
For losing channels with clean wetted perimeters (no clogging layers), the seepage rate varies essentially linearly with depth to groundwater if the groundwater is relatively shallow,...
1987-88 Actions on El Paso vs. New Mexico
It has been determined by the City of El Paso that water wells near the Texas-New Mexico borders should be used to supplement their water supply in the years 2000-2020. Opposition to the...
A Method for `Warped Surface' Land Forming Design
Most approaches to land forming are based on a plane surface design which in some cases may result in prohibitive costs or excessive removal of top soil....
Simulation of Post-irrigation Moisture Changes for Surface Irrigation of Corn
An attempt has been made to refine prediction of irrigation efficiency obtained at the end of an irrigation by accounting for the losses that occur during redistribution. The water budget...
Drainage Laws and Organizations
The legal issues associated with drainage relate to repelling diffused surface water at the boundaries of one's land as well as with disposing of excess water once it has...
Underdrain Tube Wall, Perforation Design and OBPA to Minimize Bio-Chemical Clogging
Bio-chemical clogging of underdrains has been most frequently associated with iron deposits (ochre). The underlying sticking agents have been a variety of bacteria and their exudates commonly...
Adsorption, Desorption and Transport of Pesticides in Groundwater: A Critical Review
Adsorption and desorption are major mechanisms affecting the transport and fate of pesticides in groundwater. Equilibrium, chemical nonequilibrium and physical nonequilibrium adsorption...
Bulk Stomatal Resistance in Operational Estimates of Evapotranspiration
General relationships for estimating canopy or bulk stomatal resistance and aerodynamic resistances of grass and alfalfa reference crops for use in the Penman-J.L. Monteith equation are...
The Role of Social Sciences in the Management of Surface Water Quality in the United States
This survey paper concentrates on what social science has to say about surface water quality management. Some comments are also made on the historical development of these analytical capabilities....
Riprap Design by Modified Safety Factor Method
The Safety Factor method for designing riprap is based upon straight forward physics combining rock properties and flow characteristics. M.A. Stevens developed the method by summing the...
Design and Evaluation of Storm Water Detention Facilities Using a Design Storm and Probable Maximum Storm
When designing a storm water detention facility, both a design storm (DS) and a probable maximum storm (PMS) should be considered. The DS is used to design the facility. The PMS is used...
Analytical and Numerical Modeling at High Sediment Concentrations
Methods for classifying sediment-water mixtures according to material concentration and rheologic properties are discussed. Results from laboratory and field measurements show that bed...
Kinematics and Dynamics of Overland Flow
C. Y. Guo combined the kinematic wave approximation with Horton's infiltration formula to analytically solve the propagation of a two-dimensional overland flow on a previous...
