Optimal Design Of Aquifer Clean Up Systems Under Uncertainty Using A Neural Network And A Genetic Algorithm, Alaa H. Aly, Richard C. Peralta

We present a methodology to account for the stochastic nature of hydraulic conductivity during the design of pump-and-treat systems for aquifer cleanup. The methodology (1) uses a genetic algorithm to find the global optimal solution and (2) incorporates a neural network to model the response surface within the genetic algorithm. We apply the methodology for a real example and different optimization scenarios. The employed optimization formulation requires few hydraulic conductivity realizations. The presented approach produces a trade-off curve between reliability and treatment facility size .

We present and apply a new simulation/optimization approach for single- and multiple-planning period problems in groundwater remediation. Instead of the traditional control locations for contaminant concentrations, we use an LQC norm as a global measure of aquifer contamination (CMAX). We use response-surface constraints to represent CMAX within the optimization model. We compare the performance of formal mixed integer nonlinear programming and a genetic algorithm for several optimization scenarios.
Dam Safety Risk Assessment Modeling With Uncertainty Analysis, Sanjay Singh Chauhan
Dam Safety Risk Assessment Modeling With Uncertainty Analysis, Sanjay Singh Chauhan
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A risk-enhanced approach to dam safety risk assessment combines the benefits of the traditional approach with those of risk assessment. There is a need to automate the risk analysis calculations component of the risk assessment process so that the time and effort thus saved can be beneficially expended on strengthening risk assessment inputs.
The objectives of this study were as follows: (1) to develop a dam safety risk analysis model and demonstrate its application to risk assessment and decision analysis, and (2) to develop a framework for uncertainty analysis and demonstrate its application to dam safety risk assessment. Dartmouth Dam, …

Groundwater artificial storage and recovery (ASR) has become a favorable means in the arid west to store water produced in excess of need during winter months for use in drier times of the year. ASR may be accomplished by injection of suitable water into the groundwater system via wells to be pumped out later, or by recovery of seepage via wells from surface water impoundments or infiltration networks. This report will present pertinent hydrogeologic information for the location of an artificial groundwater storage and recovery project in Utah's northeastern Box Elder County.
Conjunctive Use Of Surface Water And Groundwater For Sustainable Agricultural Production, Richard C. Peralta
Conjunctive Use Of Surface Water And Groundwater For Sustainable Agricultural Production, Richard C. Peralta
Civil and Environmental Engineering Faculty Publications
This report is a guide to aid conjunctive water use in stream-aquifer systems. Conjunctive use refers to coordinated use of groundwater and surface water resources. This document discusses principles useful for field engineers and agricultural experts. It presents hydrologic and hydraulic principles and quantitative and qualitative parameters relating to sustainable conjunctive use. It provides tools and software.

SINMAP 2.0 (Stability Index MAPping) is an ArcGIS 9.0 plug-in that implements the computation and mapping of a slope stability index based upon geographic information, primarily digital elevation data. This report describes the theoretical basis for the calculation of the stability index, describes the implementation, presents several case studies and describes use of the accompanying software. SINMAP has its theoretical basis in the infinite plane slope stability model with wetness (pore pressures) obtained from a topographically based steady state model of hydrology. Digital elevation model (DEM) methods are used to obtain the necessary input information (slope and specific catchment area). …
