Hydrochemical Modeling of Water Quality in a Ground and Surface Water System within a Semi-Urban Watershed

Advances in Analytical Modeling of Torsional Members
The basic formula for calculating the torsional strength of reinforced concrete members was developed by Rausch (1929) using the space truss concept. Unfortunately, Rausch's equation may...

Members Subjected to Torsion Combined with Other Actions
The combination of torsion with bending and shear (T-M-V) in members with both transverse and longitudinal reinforcement is the most commonly encountered combination in practical cases....

Application of TOPNET in the Distributed Model Intercomparison Project (DMIP)
This paper describes the application of a networked version of TOPMODEL, TOPNET, as part of the Distributed Model Intercomparison Project, DMIP. The model implementation is based on a...

Estimating the Return Period of Multiyear Droughts
Characterizing the return period of hydrologic events has been an important subject in water resources planning and management studies for many decades. The alternative approach has been...

A Participatory Approach to Development of a Decision Support Tool
Effective decision-making in water management must consider both the physical characteristics of the system and the social, political, and institutional aspects. These latter aspects cannot...

Optimal Selection of Rechlorinization Station in Water Distribution System by Optimization Techniques
The optimal rechlorination in water distribution systems was investigated by incorporating optimization techniques into a numerical water quality model (EPANET2). Four types of optimization...

Analysis
This chapter presents a brief overview of the current analytical modeling techniques for isolated structures. Perhaps the biggest challenge in the design of an isolated structure is incorporating...

Lesssons Learned from Experience Dealing with Risks of Extreme Events: Part II
For every known IS vulnerability, there is a matching countermeasure. However, we do not know all IS vulnerabilities. The following tasks are geared towards identifying IS vulnerabilities,...

Nonlocal Integral Formulations of Plasticity and Damage: Survey of Progress
Modeling of the evolution of distributed damage such as microcracking, void formation, and softening frictional slip necessitates strain-softening constitutive models. The nonlocal continuum...

Mathematical Modeling of Watershed Hydrology
Mathematical modeling of watershed hydrology is employed to address a wide spectrum of environmental and water resources problems. A historical perspective of hydrologic modeling is provided,...

Application of `SWAT2000' for Hydrological Modeling of Small Watershed in Eastern India
The present study deals with an application of a physically based continuous hydrological model (SWAT2000) forhydrological modeling of small agricultural watershed of Gowai river catchment...

Assessment of Water Quality Monitoring Sites by an Optimization Method
Allocation of sampling sites is the initial and the most crucial step of the water quality monitoring network design and redesign process. Several different approaches have been used within...

Impact of Chemically-Induced Clay Transport and Deposition on the Hydraulic Conductivity of a Natural Sand
The purpose of this paper is to understand in part the dynamic impact of surfactants on hydraulic conductivity for designing enhanced pump and treat operations. This paper has two aims:...

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...

Neponset Fish Passage and Habitat Restoration Project
This project was initiated to examine the feasibility of restoring fish passage, aquatic habitat and riparian habitat on the downstream reach of the Neponset River in Milton and Boston,...

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,...

Decision Support System for Daily Real-Time Operations in the Geum River Basin, Korea
A joint international collaboration between the Korea Water Resources Corporation (KOWACO) and Colorado State University (CSU) has resulted in development of a decision support system...

The Accuracy of Extrapolated Design Estimates with Hydrologic and Environmental Models
Extrapolation error in water resources and environmental modeling has not been the subject of adequate study in the past. In research and design, estimates obtained from regression models...

Development and Application of a Decision Support System for Municipal Water Infrastructure Planning: Challenges and Successes
Many water utilities across the country continue to face the challenge of intelligent planning for cost effective, efficient operation, larger demands, stricter government regulations,...
