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...

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...

How Far along the Learning Curve is the Contingent Valuation Method?
The paper discusses an application of the learning curve concept to new benefit methodologies and applies the model to the contingent valuation (CV) methodology. As knowledge accumulates...

Demand Management and Urban Water Supply Planning
During the past twenty years, the social sciences research has been translated into new methods and techniques of analysis which enable planners to evaluate the role of demand management...

Evaluating Flood Hazards on Alluvial Fans
In 1982, the Federal Emergency Management Agency (FEMA) developed a methodology for the determination of flood hazard zones and base (100-year) flood elevations on alluvial fans for administering...

Probabilistic Maintenance Opportunities
The Bureau of Reclamation has instituted a number of operation and maintenance oversight activities to ensure that Reclamation and water-user operated projects are operated and maintained...

Alluvial Fan Flooding and Development Alternatives
The Federal Emergency Management Agency (FEMA) utilizes a methodology which examines the probability of an incised channel forming at any given location across the fan, in consideration...

Hydrograph Timebase
Based on the study of a large number of hydrographs, a graphic solution is presented whereby the length of the hydrograph timebase can be directly read from the proposed graphic solution...

Finite Element Modeling in Free-Surface Hydromechanics
A finite element semi-discrete approximation is applied to the conservation law form of the two-dimensional, depth-averaged free-surface Navier-Stokes equations governing incompressible...

Stream Flow Model for a Coastal Stream in Egypt
The Coastal region north of Egypt contains many small streams known as Wadis which are considered the main water resources in that region. All the Wadis in the north coast of Egypt run...

Entropy as a Probability Concept in Energy-Gradient Distribution
The concept of entropy based on probability theory instead of thermodynamic principle has been applied to study the distribution of energy gradient along alluvial rivers. The formulas...

Fractional-Step Method for Two-Dimensional Estuarine Transport
The fractional-step method was used in this study to split the longitudinal advective transport term from the other terms in the two-dimensional, laterally-averaged equation for estuarine...

A Numerical Solution Technique for Incompressible Flow
Presented is a numerical solution technique which employs the explicit predictor-corrector scheme of R.W. MacCormack in solving the governing two-dimensional equations of motion on a staggered...

Two-Dimensional River Modeling of Buckhorn Creek
A two-dimensional Finite Element Surface Water Modeling System (FESWMS-2DH) was used to simulate flow at a bridge crossing of a heavily vegetated flood plain where State Highway 130 crosses...

Stormwater Management by Utility Approach
Traditional methods of financing municipal stormwater operations and improvements through general city fund revenues has passed. A utility approach providing a continuous, uniform flow...

Identification of Automation Opportunities
Construction, although the world's largest industry, is also its most archaic. Most construction practices are very labor-intensive, with resulting impacts on safety, productivity,...

Generation of Native FE in Lunar Soil
Electron Spin Resonance (ESR) studies on lunar samples produced some unexpected results which led to recognition of the presence of abundant single-domain Fe^o...

Concrete Habitable Structure on the Moon
This paper presents construction methods for a concrete habitable structure on the Moon. The study was conducted on the assumption that a concrete manufacturing plant has already been...

A Methodology for Modeling Construction Requirements for a Manned Lunar Base
Before accurate modeling and planning of a manned lunar base can be accomplished, a methodology representing the construction-and-assembly process of lunar surface facilities must be developed....

Explosives Research for Lunar Applications: A Review
Experimental explosives research for lunar operations is reviewed. Each research project had a different objective and together their findings showed that using explosives on the moon...
