Waenhuiskrans: Sediment Budget and Reactivation of a Sediment Pathway
Erosion of beaches due to historical dune stabilisation work carried out at Waenhuiskrans, a holiday village on the south-east coast of South Africa, prompted the need for the reactivation...
The Ebro Delta Project: A First Sediment Budget
In this paper, a sedimentary budget for the Ebro delta coast in the Western Mediterranean is presented. Calculations have been performed after one year of field campaign. The main result...
Characteristics of Colloids in Landfill Leachate
Leachate was collected from a municipal landfill which has been closed for about 15 years. The sample was collected (under a N2 atmosphere) only...
Along the Road to K
Allegations of threats from toxic and hazardous wastes advanced on political and emotional planes threaten, themselves, to overshadow the facts that should dominate ultimate technical...
High Level Radioactive Waste Management 1991
The proceedings of the second annual international conference on High Level Radioactive Waste Management, held on April 28 - May 3, 1991, Las Vegas, Nevada, provides information on the...
Probing the Golden Gate
The Golden Gate Bridge has just come through the most detailed analysis ever attempted in its 53-year-old history. This analysis was squeezed into a desktop computer that calculates twice...
Consideration of Sedimentation on Hydropower Projects
Experience gained by analysis of a number of hydropower projects throughout the world leads to the conclusion that it is necessary to consider sediment related aspects in the design and...
Estimation of Loading via Fingered Flow
Results of experimental investigations of fingered preferential flow are combined into a concise, conservative engineering methodology for predicting pollutant transport through fingered...
Impact of Grid Orientation on Groundwater Contaminant Transport Modeling Using the U.S.G.S. MOC Model
The U.S.G.S. method of characteristics (MOC) model was enhanced to include the input of measured contaminant concentrations, the calculation of computed and measured contaminant plume...
Pitfalls Associated with the Assumption of a Constant Partition Coefficient in Modeling Sorbing Solute Transport Through the Subsurface
This paper presents several case studies where the estimation of the adsorption coefficient, Kd, by means of the Koc-foc...
Modeling of Reactive Chemical Transport of Leachates from a Utility Fly-Ash Disposal Site
Fly ash from fossil-fuel power plants is commonly slurried and pumped to disposal sites. The utility industry is interested in finding out whether any hazardous constituents might leach...
2-D Groundwater Transport of Reactive Solutes with Competitive Adsorption
This paper presents a 2-D model, with applications, for the groundwater transport with competitive adsorption of a metal, a ligand and a complex. The model, called METLI, computes advection-dominated...
Monte Carlo Simulation of Transport from Reserve Pits
A mathematical modeling study was performed to evaluate potential health and environmental risks due to contaminant transport from exploration and production well freshwater drilling mud...
Simulation of Leachate Discharge from a Small Island into a Tidal Bay
A small island in a tidal bay was considered as a potential site for depositing large volumes of excavation material from a transportation project. The island is located in the inner part...
Buoyant, Miscible Plume in Heterogeneous Aquifer
A three-dimensional, particle tracking scheme is used to compute the trajectory of and spread about the centroid of a mass slug added to steady flow through an infinite aquifer with an...
Sediment Transport Measurements in the Nile River at Bani Mazar
Measurements of sediment transport on the Nile River were conducted at Bani Mazar (200 km South of Cairo) during high and low water stages. Bed-load and suspended-load transport rates...
Application of Stable Channel Design Method
Systematic stable channel design methods are currently being developed by the US Army Engineer Waterways Experiment Station for use in the planning stages of local flood control projects....
Pump Station/Storage Opportunities for Urban Freeway Systems
This paper introduces the concept of utilizing underground storage to minimize both the initial cost and the long-term maintenance and operation costs of multiple pump stations for a freeway...
Optimizing Regional Detention Basins for Price Expressway
Stormwater runoff from the drainage area contributing to the Price-Santan Freeway is captured in regional detention basins which require a series of pump stations for evacuation. With...
New Lessons About the Hydraulic Performance of Highway Storm Sewer Inlets
Laboratory experiments were performed with highway storm water curb inlets to 1) reduce the oblique standing wave that extends into the highway from the downstream side of the inlet and...
