Optimization Model for Operation of Recharge Basins
A mathematical model is developed for the optimal operation of recharge basins, which is a non-linear optimization problem. The objective of the model is to determine the operation that...
Computer Modeling Responsibilities for Municipalities
Municipal organizations are often faced with a complex set of water resource problems which can best be analyzed through the use of computer models. The development of such models can...
Bodkin Island Wetland Restoration Project Design
Bodkin Island in the Chesapeake Bay will be increased by 2 hectares through placement of dredged material to create nesting and brood habitat for black ducks. The enlarged island will...
Three Dimensional Modeling of Watershed Hydrology
A three dimensional finite element numerical model is developed for the first order watershed hydrology using 8-noded isoparametric brick elements. The 3-D subsurface flow in a hillslope...
Prediction and Sensitivity of Recharges Due to Rainfall
This paper evaluates two models for predicting recharges due to rainfall: i) a simple mass balance model, and ii) a numerical model using the commercial software, UNSAT1. The models differ...
Indicator Variography for Spatial Characterization of Aquifer Heterogeneities
The qualitative information or soft data from lithologic descriptions is processed using a state-of-the-art geostatistical approach to delineate, with quantified uncertainty, the extent...
Wetland Restoration and Creation Guidelines for Mitigation
The majority of wetland mitigation projects built in the U.S. are failures. Reasons for failure include poor siting, improper design (including inadequate baseline data collection), inadequate...
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...
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...

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...
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,...
Forensic Analysis Techniques for Joint Sealants
Growing concerns involving the field performance of pavement joint sealant materials has illustrated the need for forensic capabilities in determining the cause of sealant failures. Methods...
Reliability-Based Design for Feeeze-Thaw Concrete
Observation of pavements in Iowa shows results from the test for freezing and thawing of concrete, ASTM C-666, is not always consistent with field performance. Similar concrete made with...
Probabilistic Mechanics and Structural and Geotechnical Reliability
This proceedings consists of summary papers for the thirty-six technical sessions of the 6th ASCE Specialty Conference on Probabilistic Mechanics, and Structural and Geotechnical Reliability....
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...
Taming Environmental Data
The main problem with environmental management is the vast quantity of data generated for and by analysis. A computer system designed to solve this problem moves data from the database...
Regional Evaluation of Transportation Lifelines in New York State with the Aid of GIS Technology
Regional evaluation of transportation lifeline facilities which may be impacted by seismic and other natural hazards is of great concern for purposes of emergency planning and response...
The Superposition Approach to Pile Group Dynamics
A general three-dimensional boundary integral formulation for pile groups is used to obtain a set of dynamic interaction factors for a number of soil profiles and for a wide range of pile...
