Lessons Learned from the Certification of Graving Docks, Marine Railways, Vertical Lifts and Shipbuilding Ways
Because of the hazards which exist during the ship docking, undocking, launching and while the ship is being built or repaired, the Navy has determined a requirement exists for system...
Soil-Structure Interaction in Seismic Environments
Soil-structure interaction depends on the mass, stiffness and the damping of the structure as well as on the geometry and embedment of the foundation and on the properties of the soil....
Tiebacks for Bulkheads
Tiebacks were once used primarily to support temporary structures such as supported excavations. However, the use of tiebacks has been gradually expanded to include the support of permanent...
Asphalt Pavement Modifiers
Modifiers or additives to asphalt concrete pavements are being researched or marketed by many major chemical firms. Modifiers or additives are used to stiffen the asphalt in hot weather...
Pressuremeter Tests and Shoring Wall Design
Pressuremeter testing was used as an integral part in the design of the temporary tieback shoring wall for the Columbia Center office building in Seattle, Washington. Pressuremeter testing...
Special Water Treatment in New Jersey
The New Jersey Department of Environmental Protection (NJDEP) performed a study on 'special water treatment'. The main goal of the project was to assess in detail...

An overview of two computer models and a nomograph model for sulfide prediction is presented. The first program, 'SULF. BAS', is a Basic Language computer model...
Diamond Fork Hydroelectric Power Development
The Strawberry Valley Project was conceived in the early 1890s as an irrigation project to supply a maximum of 635 cfs of water from the Strawberry Reservoir through a 3. 8-mile-long tunnel...
Stormwater Management in Kansas
This paper evaluates the current stormwater management practices of Kansas cities. This evaluation is based on a survey of all Kansas cities with populations over 10,000. Issues examined...
Optimization, Simulation and Multiobjective Analysis of Operating Rules for Reservoir Systems
In this paper, three steps are proposed for establishing reservoir operating rules which can be used in real-time without flow forecasting. In the first step, optimization models are used...
Water Resources Systems Planning: Differential Dynamic Programming Models
A Monte Carlo optimization methodology is presented for water resources systems. The planning model define the optimal storage and release policies for the reservoir system. The optimization...
Math Modeling of Mixing Zones in River Systems
A numerical mixing zone model was developed utilizing an implicit finite difference method with a weighted numerical scheme. The model was based on the two-dimensional advection-dispersion...
Computer Aided Drafting in the Water Resources Environment
The movement from traditional mechanical drafting to computer aided drafting in the small consulting business/research environment while necessary from the viewpoint of productivity and...
Interactive simulation of Water Resource Systems
This paper outlines some of the research currently underway at Cornell aimed at the design of an interactive simulation methododology. It describes the general approach to simulation modeling,...
Advection Calculations Using Spline Schemes
The calculation of advective transport in one and two dimensions is done by the method of characteristics using spline interpolating polynomials at the forward time step. The method has...
Use of Stochastic Hydrology in Reservoir Operation
The Bureau of Reclamation is incorporating stochastic traces to provide a broader basis for management decisions during drought periods for the Central Valley Project in California. A...
Instream Flow Needs to Protect Fishery Resources
Numerous methods have been developed over the past several decades to assess the effects of flow regulation on fishery resources and to provide a basis for the determination of suitable...
Construction of Roller-Compacted Concrete Pavement
Roller-compacted concrete pavement (RCCP) is the product of a relatively new concrete paving technology in which a zero-slump portland cement concrete mixture is spread with modified asphalt...
