Fran-Spotting
When Hurricane Fran slammed into the North Carolina coast last September, it ravaged a fragile barrier island system already torn up by Hurricane Bertha two months before. The result was...
Water Wisdom of the Ancients
Two water systems thousands of years old--the falaj system in Oman and China's Dujiangyan water works--are still in use today. A climatologist describes how these systems...
Depth-Averaged Boussinesq Equations Applied to Flow in a Converging Channel
Supereritical flow in a contracting channel is simulated by numerically solving the 2D depth-averaged Boussinesq equations using a fmite-difference model DASH (Molls and Chaudhry 1995,...
Dam Foundation Erosion Study: The Design of a Sidewall Orifice for Simulation of a Free Trajectory Overtopping Jet
This paper describes the design of a sidewall discharging orifice for simulation of a free trajectory overtopping jet. A sidewall orifice discharges through the sidewall of a pipe. The...
SpatioTemporal Stochastic Open-Dhannel Flow
The de Saint Venant equations are solved as stochastic partial differential equations whose parameters (hydraulic resistance, bed slope, cross-section geometiy, inflow hydrograph, seepage,...
Rational Design and Operation of Packed Bed Adsorption Reactors
Design of packed bed adsorption reactors is based presently upon the parameter empty bed contact time (EBCT), a fallacious concept. The column wave front behavior, instead, should be the...
Development of a Regional Atmospheric-Hydrologic Model for the Study of Climate Change in California
An integrated model of atmospheric and hydrologic processes at regional scale over California has been developed in order to translate the large scale atmospheric conditions of critical...
Coastal Engineering Laboratory and Field Measurements: Some Uncertainties in Measurement
In this paper two examples of uncertainties which can occur in field measurements and measurements in coastal engineering models are examined. These examples are chosen to demonstrate...
Looking for Evidence of Climatic Change in Streamflow Time Series
The principle of stationarity of a streamflow time series has been very commonly assumed in the analysis of hydrologic time series. Some common types of non-stationarity in time series,...
The Effect of Climatic Change on Hydrologic Variables
There has been increasing concern about the threat of global warming affecting the earth's climate. This warming scenario, called the greenhouse effect, is believed to be...
Climate Change: What the North American Water Engineer Should Know
Long-range forecasts of future global warming have been made based on the increase in carbon dioxide and trace gases in the air from human activities. Potential changes which would especially...
Public Attitudes, Behavior, and the Willingness to Sacrifice to Mitigate Uncertain Adversity: Water Management Implications for Climate Change
Although several scholars have touted the emergence of a new environmentalism, many Americans seem to make decisions that do not reflect green thinking. Examples include driving more miles...
Modeling Climate Change Impacts on Water Resources
As part of the Electric Power Research Institute's (EPRI) comprehensive evaluation of the economic effects of climate change in the United States, we have developed methods...
Climate Variability Impact on the Water Resources of Ancient Andean Civilizations
The great ancient empires of South America used corporate irrigated agriculture with centralized control to help hold far-flung domains together. The Inca empire, larger in area than that...
Stormwater Management Plan Updated for Climate System Changes
When large watershed stormwater management plans are updated, climate system change factors due to global warming effects should be considered. Climate system changes may cause changes...
Modeling Unsteady Open-Channel Flows Having Longitudinally Varied Fluid Density
Unsteady flows in waterways with fluid density varying longitudinally can be described by various sets of partial differential equations, according to conditions of density variation....
Vulnerability of Water Resources to Global Climate Change in the Agricultural Midwest- Ecological, Economic, and Regulatory Aspects
As climate changes, so will water resources. General climate change will alter the distribution of hydrometeorological events and will affect water use, in turn resulting in further alterations...
Forcing Function and Climate Change
A system framework for investigating the effect of climate change in the upper Rio-Grande river basin, New Mexico, is developed. The forcing function or input into a climate change model...
Integrated Hydrological/Ecological/Economic Modeling for Examining the Vulnerability of Water Resources to Climate Change
A methodology for assessing regional-scale hydrologic vulnerability to climate variability which incorporates ecologic and economic factors is presented. A simple economic model of damages...
Adapting Water Resources of the Canadian Prairies under the impact of Climatic Warming
Given that future droughts could become more frequent and more severe because of climatic warming, this paper discusses some strategies to manage and to develop the water resources of...
