Reliability of Operating Rules with or without Uncertain Forecasts
In this study the reliability indices are calculated for operating policies generated by three Stochastic Dynamic optimization models: a classical Stochastic Dynamic Programming (SDP);...

Probability of Bridge Failure Due to Pier Scour
Methods have been presented for computing the probability of bridge failure due to pier scour either using a maximum scour depth model or a time-dependent model. The probability of failure...

Proposed Development of South Central Florida Hydrologic Ecosystem Model
The Corps of Engineers has been authorized to develop and operate a simulation model of the hydrologic ecosystem of central and south Florida. This ecosystem is fragile and complex, and...

Water Management as an Instrument for Cooperation and Reconciliation
Empirical models for identifying potential water quantity and water quality conflicts in water resources development are presented. These planning models are applied to a previously developed...

The Importance of Verified Simulation Model in a Sewerage Rehabilitation Program
In the past as structural, water quality and flooding problems occurred in a sewer system they were dealt with by crisis management. A better approach is now available using the latest...

A Chance Constrained Optimization Model Using Kinematic Wave Routing for Stormwater Infrastructure Rehabilitation
A chance constrained optimization model is presented to determine efficient long-term replacement strategies for segments of stormwater drainage systems. The model is multiobjective in...

Analytical Hydraulic Modeling of Road Culverts
This paper summarizes the development of a comprehensive analytical methodology and a computer model capable of simulating a wide range of flow phenomena in road culverts. The new flow...

Reservoir Water Quality Modeling in Northern Portugal?Some Case Studies
In the last two decades environmental problems have become a major concern in Portugal as the effects of water pollution have gradually impaired the quality of water resources. Mathematical...

Hillsboro Basin Surface Water Management Model
This study presents the results of the hydrologic and hydraulic analysis of the 103-square mile Hillsboro Basin located in South Florida. The purposes of the project were to develop a...

Modeling Nutrient Loadings from Croplands in the Chesapeake Bay Watershed
The Chesapeake Bay Watershed Model, based on the U.S. EPA Hydrologic Simulation Program Fortran (HSPF) provides a framework for evaluating and quantifying nutrient loadings to the Chesapeake...

BRASS Modeling of Lo?za Reservoir, Puerto Rico, for Sediment Management Operations
Loiza reservoir, the principal water supply for metropolitan San Juan, delivers 3.5 m3/s (80 mgd) to the Sergio Cuevas filter plant. Sedimentation...

Modeling Stormwater Basin Effects
This paper presents results of an extension to a study included earlier in these proceedings on the downstream accumulation effects of stormwater detention basins. The previously calibrated...

Optimal Aquifer Management for Controlling Land Subsidence
This paper discusses on-going research in optimal regional aquifer management that has a multiplicity of goals: water supply, subsidence control, and energy management. Current research...

A TVD MacCormack Method for Open Water Hydraulics and Transport

Site Impact Traffic Assessment
Problems and Solutions
Transportation needs have traditionally derived from land use decisions. Site impact traffic analysis is a formalized process that attempts to quantify the need for transportation improvements...

A More Rational Approach to Pavements
It is the intent of this paper to demonstrate how purely probabilistic arguments can be used to formulate a rational (phenomenonological) model of the particulate media that comprise pavement...

Estuarine and Coastal Modeling
This is the proceedings of the second ASCE specialty conference on Estuarine and Coastal Modeling devoted to the rapidly evolving field of marine environmental modeling. The primary focus...

Migration of Spilled Oil from Ruptured Underground Crude Oil Pipelines in the Memphis Area
This study evaluated the impact of an oil pipeline rupture in the recharge area of a West Tennessee aquifer. Two potential break locations were chosen in the alluvial valley of a main...

An Assessment of Environmental Costs Associated with Crude Oil Pipeline Damage Caused by Earthquakes
This paper presents a methodology for assessing the risk of environmental contamination from oil pipeline leaks caused by earthquakes. Risk is measured both as volume of oil released and...

Response of Model Pile Groups to Strong Shaking
The dynamic responses of small model pile groups to strong shaking obtained primarily from shake table tests are described and analyzed. As a basis for understanding pile group response,...
