Distributed Parameter Hydrologic Modeling and NEXRAD for River Forecasting: Scale Issues Facing the National Weather Service
With the advent of NEXRAD (Next Generation RADar), the National Weather Service has the opportunity to move from current lumped parameter modeling to more of a distributed parameter hydrologic...

Dormant Season Evaporation: Challenges to the Current Models
Dormant season evaporation is a critical component of the hydrologic balance and can be considered as the winter period or the time in which there is not a crop actively growing. It is...

Hydraulic and Engineering Considerations in Designing Constructed Treatment Wetlands for a Lake Restoration
A 12,600 ha (31,000 acre) hypereutrophic lake in central Florida is being restored by constructing a 2,020 ha (5,000 acre) wetland filter to remove suspended sediments and particulate...

FLODRO 2.0: A User Friendly Personal Computer Package for Flood and Drought Frequency Analyses
The use of personal computers have changed dramatically the way to perform several studies related with hydrological problems. The increased capabilities of the current generation of personal...

Analysis of Bank Stabilization in Steep Complex Streams Using A Two-Dimensional Model
In cases where the channel is fairly uniform, and not divided, one-dimensional hydraulic models, such as HEC-2, generally give adequate results for scour evaluations and bank protection...

Genetic Algorithm Design of Piped Irrigation Systems
The design of piped irrigation systems is a complex matter. In its simplest form it involves the selection of the sizes of pipes and other hydraulic elements so as to ensure that the varying...

Value Engineering Changes to the Eastside Pipeline
Value Engineering is a process of applying analytic, creative and evaluative techniques to a project in order to make recommendations that will, when implemented, maximize value and quality...

Concept Ecology Integrated Project Engineering and Environment; Relating a Project to the Surroundings
The selected alignment of the 27.3 km long Veterans Expressway in Tampa, Florida was constructed for better access to the downtown area from a relatively rural but fast growing area of...

Overview of Drought Response Strategies
An overview of drought response strategies in the United States is presented. The paper focuses on tactical strategies for mitigating the impacts of drought conditions. A general structure...

Water Conservation Definitions From a Hydrologic Viewpoint
The definition of water management principles needed to satisfy societys water use objectives requires the use of terms and definitions that clearly describe the effects of various water...

Application of the Newton Method in Valve Discharge Coefficient Relationships
This paper presents a methodology that utilizes the Newton Method to compute the dimensionless valve discharge coefficient Cd from a manufacturers valve discharge coefficient Cv. The implicit...

Rethinking Well Efficiency
Many authors have suggested ways to evaluate water well efficiency. Most of these have either compared some form of measured drawdown with theoretical drawdown or measured the fraction...

Hydrodynamic Simulations in Sediment-Carried Contaminant Modeling for the Buffalo River, New York
Accurate prediction of hydrodynamics is of great importance to modeling contaminant transport and water quality in a river and to estimating potential exposure contamination levels in...

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...

Experimental Uncertainty and Measurement Errors in Hydraulic Engineering
The Task Committee on Experimental Uncertainty and Measurement Errors was formed to provide information and guidance on current practices used for describing and quantifying measurement...

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...

Estimation of Flash Flood Potential for Large Areas
A methodology for determining the potential for flash floods in small basins within large geographical areas is presented. Geographical Information Systems (GIS) technology is used to...

1995: Where the Past (Paleoflood Hydrology) Meets the Present, Understanding Maximum Flooding
Paleoflood hydrology has become accepted in the scientific, engineering, and regulatory communities and increasingly is being used to complement engineering hydrology throughout the Rocky...

The Importance of Plant Community Structure on Form and Function of Created Wetland Systems
If we consider that the creation and the restoration of a wetland system begins with the design of the hydrology, then establishing the form and function of a wetland begins with the design...

Indianapolis Uses New Radar Technology to Refine Hyetographs for CSO Model and SSES Studies
Indianapolis is the first city in the country to install the French-developed technology designed by urban hydrologists to accurately measure rainfall between rain gauges. Installed in...
