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,...

Spectral and Bispectral Analysis for Nonlinear Leaky Phreatic Aquifer Systems Subject to Time Variable Inputs

Numerical Study on Effects of Leakage from Phreatic Aquifer on Flow in Confined Aquifer

Management of Stream-Aquifer Systems in the 21st Century
Many water agencies, especially those in the arid and semi-arid southwest of United States rely on stream-aquifer systems for a significant proportion of their water supplies. Wastewater...

Analysis of Hydraulic Barriers for Ground Water in Stream-Aquifer Systems

Optimal State Feedback Estimation in Groundwater: Application to Leaky Aquifers
The problem of groundwater flow in leaky aquifer is looked at from a stochastic point of view. Optimal estimation of hydraulic heads are achieved using Kalman filtering. The Kalman filtering...

Lake-Level Declines in Karst Lake During Droughts
Lake-level declines in Brooklyn Lake, a karst lake in north-central Florida, have been investigated. Below average rainfall, vertical leakage to the underlying aquifer system, declining...

Modeling Contaminant Migration from an Unlined Pond
A hybrid one-dimensional (1-D) vertical model coupled with a two-dimensional (2-D) aquifer model was applied to study the fate and transport of arsenic, fluoride, and orthophosphate resulting...

Modeling Stream-Aquifer Interaction for Water Rights Administration

Optimizing Conjunctive Water Use in a Dynamic Stream-Aquifer System with US/REMAX
Long-term water management planning models frequently use large time steps and must employ fairly crude assumptions (such as average climatic conditions, etc.). Managing stream aquifer...

Well Response in a Leaky Aquifer and Computational Interpretation of Pumping Tests
An analytic solution is derived describing flow in a horizontal confined leaky aquifer of infinite extent around a fully penetrating well of negligible storage capacity. The differences...

Concentration History During Pumping from a Leaky Aquifer with Stratified Initial Concentration
Analytical and numerical solutions are employed to examine the concentration history of a dissolved substance in water pumped from a leaky aquifer. Many aquifer systems are characterized...

Development of a Two-Layered Groundwater Model for the Taipei Basin
The objective of this paper is to develop a groundwater model for flow simulation in the Taipei basin. A conceptual model of the basin is first developed; the model consists of an upper...

Use of D-C Resistivity to Map Saline Ground Water
It has been estimated in previous studies that 23 square miles of the Oxnard aquifer, a member of a multi-layered aquifer system beneath the Oxnard plain in Ventura County, California,...

Optimal Capacity Expansion in Multi-Aquifer Systems
A deterministic optimization model is presented for analyzing the capacity expansion policies in multi aquifer systems. The response of the system is included in the optimization model...

Role of Soil-Aquifer Treatment in Water Reuse
Reuse of municipal wastewater requires treatment so that the water meets the quality requirements for the intended use. Irrigation of vegetables consumed raw requires absence of pathogenic...

Effect on Soil and Groundwater Due to Long-Term Land Treatment
A comprehensive assessment of the environmental impact of a full-scale, operating overland flow (OLF) land treatment system was made of the Campbell Soup, Inc. OLF system in Paris, Texas....

Effects of Wastewater Irrigation on Aqueous Geochemistry
A comprehensive assessment of the environmental impact of a full-scale, operating overland flow (OLF) land treatment system was made of the Campbell Soup, Inc. OLF system in Paris, Texas....

Determination of Vertical Leakage for Nile Valley
The determination of vertical groundwater leakage is particularly important for irrigated agriculture where adequate drainage is required to prevent high water tables and related problems...

Stochastic Model for the Management of a Stream-Aquifer System
The management of a system of groundwater and surface water requires that the hydraulic connection of the two sources be investigated. The inherent uncertainties that exist in the data,...
