Enhancing the Solution of Large Monitoring Network Design Problems Using a New Epsilon-Dominance Hierarchical Bayesian Optimization Algorithm
Designing long-term monitoring (LTM) networks for contaminated groundwater is a challenging problem that has long been recognized to suffer from the curse of dimensionality. LTM design...
Concentrated Animal Feeding Operations (CAFOs) and Nitrogen Conversions in the Groundwater Environment
EPA's regulatory focus on concentrated animal feeding operations has historically concentrated on potential surface water impacts from direct discharges as well as nutrient-laden runoff....
Hydrologic Comparison of Four Types of Permeable Pavement and Standard Asphalt in Eastern North Carolina
A permeable pavement parking lot in eastern North Carolina consisting of four types of permeable pavement and standard asphalt was monitored from June 2006 to July 2007 for hydrologic...
Probabilistic Analysis of Long-Term Aquifer Recharge
Long-term time series of aquifer recharge and other aquifer fluxes (aquifer discharge, groundwater extraction) are essential to monitor and understand aquifer processes. This paper presents...
Optimization of Well Placement in Groundwater Long Term Monitoring Networks
Long Term Monitoring (LTM) networks play critical roles in tracking the migration of contaminants in groundwater, evaluating the efficiency of the existing remediation techniques, and...
Modeling Fort Ord Site OU2's Remediation System Using Optimization
Fort Ord.s Site OU2 is located approximately 80 miles south of San Francisco near Monterey Bay in Monterey County, California. Fort Ord contains two landfills which were used for residential...
Some Case Histories of Pile Foundations in Permafrost
Foundations for permafrost conditions should conform to one of three basic design principles: keep it frozen, let it thaw, or thaw the ground before construction. To keep the permafrost...
Characterizing the Pathways and Characteristics of Nutrients Discharging from Ground-Water to Surface Water
Any investigation of surface-water quality for a lake or pond requires accurate estimates of the contributing contaminant or nutrient loads. In many cases, inflow from the adjacent ground...
Characterization of Interaction of Surface Water and Groundwater in the El Paso Lower Valley of Texas
El Paso is located in the Chihuahua desert and prone to long periods of extreme drought. With the river drought, regional irrigation districts only received 34% and 38%of a full water...
Headcut Analysis for Off-Channel Gravel Pits in Arid Environments
The study focuses on a large gravel pit located adjacent to the Santa Cruz River between the confluences with the Rillito and Canada del Oro rivers in Tucson, Arizona. These gravel pits...
Stochastic Analysis of the Truckee River Flow System
The Truckee River system is a complex system that involves a number of hydraulic structures such as natural and artificial lakes and reservoirs and diversions. Streamflow data have been...
Liquid Assets
Educational Facilities and the fountains of a new plaza are making good use of water from a system that is remediating contaminated groundwater in Wichita, Kansas....
Reconstructed With Precision
Rehabilitating a heavily traveled crossing while traffic continues to flow is a complicated endeavor. Add the attention to detail required to preserve the character of a historic 1920's...
Long-Term Groundwater Monitoring
The State of the Art
Prepared by the Task Committee on the State of the Art in Long-Term Groundwater Monitoring Design of the Environmental and Water Resources Institute of ASCE. ...
What Is Hydraulic Engineering?
This paper, written to mark ASCE's 150th anniversary, traces the role of hydraulic engineering from early or mid-twentieth-century to the beginning of the twenty-first century....
Integrated Water Management for the 21st Century: Problems and Solutions
Most of the projected global population increases will take place in third world countries that already suffer from water, food, and health problems. Increasingly, the various water uses...
Unleashing the Flow
A 70-year-old, two-lane roadway that stretches from Miami to Tamp Bay is impeding the flow of water through the Everglades. By studying eight possible solutions in detail, engineers determined...
Impact of Ground Water Management on the Hydropattern of Wetlands
In this paper, we examine the effect of altering the pumping rates of a large municipal well field, on the hydropattern of the near by PENSUCO wetland. A flow model developed earlier using...
Practical Groundwater and Conjunctive Water Optimization
The Simulation/Optimization MOdeling System (SOMOS) makes it easy to do groundwater optimization modeling for a variety of scales and situations. The SOMOA module uses analytical equations,...
Bayesian Approach to Support Design of a Groundwater Long Term Monitoring Plan
This paper discusses a retrospective data assimilation approach that allows one to examine the spatial and temporal differences between forecast and observed states. Their stability, or...
