Reservoir Operating Rules for Maximum Hydropower Production
A procedure for testing the effectiveness of reservoir operating rules for real-time, multi-purpose reservoir operation is presented. Particularly, models that may be used to achieve maximum...
A Demand Driven Decision Support System for Operation of Reservoirs
In this paper a stochastic optimization model, called Demand Driven Stochastic Dynamic Programming (DDSP) is developed and is compared with a Bayesian Stochastic Dynamic Programming (BSDP)....
Applying the ARMOS and MOFAT Models to a Major Oil Spill
A study was undertaken to evaluate the impact of a crude oil pipeline rupture in the recharge area of the aquifer serving most of West Tennessee. The main challenge was to model the volume...
Modeling of a Large-Scale Water Distribution System
Metropolitan Water District of Southern California (MWD) imports water from the California State Water Project and the Colorado River, providing for supplemental water demands for six...
Development of a Phase I Prescriptive Reservoir Model
The U.S. Army Corps of Engineers Hydrologic Engineering Center (HEC) has recently developed a Phase I generalized prescriptive reservoir model referred to as HEC-PRM. The purpose of the...
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...
