Reservoir System Reliability Constrained by Natural Salt Pollution
A generalized reservoir system simulation model, which incorporates salinity considerations, has been developed and is presently being applied to a system of 12 reservoirs in the Brazos...
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...
Water Main Rehabilitation Needs for the 1990's
Distribution systems represent the major portion of water utilities capital assets. There are growing concerns about water quality deterioration within distribution systems, and hydraulic...

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...
Reuse Rules
Cities that discharge sewage effluent to surface water are under increasing pressure to reduce concentrations of heavy metals, ammonium and nitrate, and substances such as toxic organic...
Durability Failure of a Concrete Block Port Pavement
A concrete block port pavement began showing distress after 7.5 years of use. Initial repair attempts found extensive areas of deterioration. The concrete blocks were cracking, spalling,...
Overview of Permeable Bases
Drainable pavement systems consist of: permeable base, separator lyer, and edgegrain system. This paper focuses on permable bases. A permeable base must provide both permeability and stability....
Forensic Analysis Techniques for Joint Sealants
