Effects of Climate Change on Water Quality
This research explores the potential effects of climate change on the quality of waters in lakes. Temperature and dissolved oxygen were considered the primary water quality variables due...
Modeling Temperature Impacts on Salmon Survival
Among research goals at the University of California-Davis are the development and application of mathematical models to study water quality impacts on threatened and endangered species....
Object-oriented Model of Colorado River Salinity
A salt balance is incorporated into an object-oriented river-basin model and applied to the Colorado River. The model simulates seasonal variations in the basin's water balance and employs...
Recent Advances In Well Hydraulics
Most books and papers on well hydraulics are mostly or entirely aquifer hydraulics. The phrase, 'well hydraulics,' implies a study of the flow into and within a well proper. There has...
An Alternative Formulation of Volume-change Behavior of Soils
The traditional approach based on the semi-logarithmic representation of volume change data is known to work relatively well for prediction of ground settlements. This approach has been...
Long Term Performance of Raft and Footing Foundations Above Clayey Silt
Two multistorey buildings have recently been constructed on a 30-m thick layer of clayey silt in downtown Fredericton, New Brunswick. The Bank of Montreal building is ten storeys high...
Consolidation Settlements and Pore Pressure Dissipation
A test fill was constructed off the coast of one of the outer islands in Hong Kong to evaluate the consolidation characteristics of a soft plastic clay deposit known as Hong Kong mud....
Vacuum-Assisted Consolidation of a Hydraulic Landfill
As part of the Pier 300 42-acre site ground modification project, a field test of vacuum-assisted preconsolidation of hydraulic fill was studied. The objective of the test was to assess...
Settlement of Dynamically Compacted Deposits
This paper compares predicted and measured settlements of deposits that were densified by means of dynamic compaction. Settlement records are presented for sites consisting of old, midage,...
Poorer Is Riskier: Opportunity for Change
With regard to water resources, it is appropriate to build upon two interacting themes of the late Aaron Wildavsky (1988). The first of Wildavsky's themes is the idea of resiliency. The...
Waste Minimization and Recycling by Microfiltration during Nitrocellulose Manufacturing
A plant survey was conducted to determine the amount of nitrocellulose (NC) discharged with process water from each of five sequential NC purification processes. Wastewater samples were...
Computing Two Dimensional Flood Propagation with a High Resolution Extension of McCormack's Method
McCormack's method, as applied for solving the bidimensional de Saint Venant equations is enhanced with the aid of the theory of Total Variation Diminishing (TVD) schemes in order to obtain...
An Adaptive Nine-Point Finite Volume Roe Scheme for Two-Dimensional Saint-Venant Equations
The system of Saint Venant equations is considered numerically. A Roe approximate solver coupled to a nine-point finite volume spatial discretization is introduced at the same time as...
A Control Volume Finite Element Method for the Solution of 2-D Overland Flow Problems
This article introduces the Control Volume Finite Element Method (CVFEM) for the solution of 2-D overland flow problems. The CVFEM integrates the advantages of both Finite Element (FE)...
Object-Oriented Finite Volume Dam-Break Model
This paper is devoted to Object-Oriented analysis and design techniques to two computational modules in the field of dam-breaking. The C++ Object-Oriented...
Free surface flow modelling on a complex topography
The aim of this paper is to describe the different construction stages and the validation of a free surface flow model on a complex topography. This model is based on the two dimensional...
Two-Dimensional Modelling of Flow in the River Sava
On the river Sava near Ljubljana, a sports centre with a kayak racing channel was built in 1948. For the world championship in kayak-canoe racing in 1990 totally new racing channel had...
Flood Propagation on Mobile Beds under Mountainous Flow Conditions
An implicit finite-volume scheme is used to solve the shallow water equations under mountainous flow conditions. The algorithm is stable for sub- and supercritical flows and moving internal...
A comparison between computed and measured bed evolution in a river bend
A shallow-water scheme with a movable bed has been employed in order to check the reliability of computations related to the bed evolution when a substantially three-dimensional phenomenon...
Measurement of Turbulent Properties in a Natural System
Instruments designed to measure flow properties in stratified estuaries, lakes and oceans are reviewed. Emphasis is given to the measurement of turbulent fluxes and recent developments...
