At-A-Station Temporal Variations in Flow under Drought and Flood Conditions and Associated Sediment Problems
The way flow variations take place with time under drought and flood conditions, in comparison with normal flow condition, has been investigated along with the related sediment transport...
Characterization of Canal Operations under Ideal Anticipatory Control
A dimensionless formulation of a gate.stroking model is being used to study general characteristics of control measures that need to be applied upstream in single.pool canal systems to...
Evaluation of System Downstream Control
System downstream control (SDC) has been developed to optimally and automaticaly control canal systems. The objective of system downstream control is to maintain a reference water depth...
Organizing a Local Water Resources Technical Group
Participating in a local water resource technical group can be rewarding professionally as well as socially. However, if such a group does not exist in your area, organizing one is an...
The Birth and Success of Orange County's Hydrology and Hydraulics Technical Group
The Orange County.s Hydrology and Hydraulics Technical Group (HHTG) has been very successful ever since it was founded in 1991. The HHTG is incorporated as a Technical Group under the...
Searching for Optimal Combinations of Stormwater Detention Basins
Hydrology of urban areas is dominated by two distinct characteristics: (1) a preponderance of impervious surfaces created primarily by pavement and roofs, and (2) the presence of constructed...
The Treatment Train Detention Concept
With the recent concern for nonpoint source pollution impacts to receiving waters, the Village of Saukville, Wisconsin took advantage of state funding grants to conduct a Stormwater Management...
Uncertainty Analysis of Reservoir Sedimentation
In estimating reservoir sedimentation, a number of uncertainties arise. These are related to annual streamfiow, sediment load, sediment particle size, trap efficiency, and reservoir operation....
Canal Control and Automation for the Central District System
The Central Nebraska Public Power and Irrigation District system provides irrigation and hydropower benefits in south-central Nebraska. Because of its complexity, the system relies heavily...
Hydraulic Design of Subsurface Flow Wetlands
Although Subsurface Flow Wetlands (SFW) have received steadily increasing international attention during the past 10 to 15 years, comprehensive design criteria are not available for some...
Studies on the Erosion of a Compacted Soil
In the management of water there are certain applications in which compacted soil is used (i.e., dams, embankments, levees, spiliways, and channels). Engineers rely primarily on field...
Sediment Removal from Stormwater Runoff
Sediment traps, also known as baffle boxes, are being used throughout the state of Florida to remove sediment from stomiwater. A baffle box is divided into three compartments by two bathers,...
Interdisciplinary Research of Mountainous Areas: Past, Present, and Future
In the past few years, there has been a growing recognition internationally, of a need to better understand hydrometeorologic, hydraulic, sedimentologic, geomorphic processes in gravel-,...
Selection of the Form of Calculated Flood Hydrograph in Projecting Water Release Facilities
Traditionally, in evaluating hydraulic structures, river flood runoff hydrographs are determined by maximum flood water volume and discharge, duration of the flood and some other parameters,...
Risk-based Analysis of Major Rehabilitation of Hydraulic Structures Using REPAIR
This poster session presents a demonstration of a computer model developed by the Corps of Engineers to analyze investment proposals. The primary purpose of the model is evaluate investments...
The Timberlake Dam Failure: A Hydrometeorological Assessment
Extremely heavy rainfall over the Timberlake basin in southwest Virginia on 23 June 1995 caused an earthen dam to fail and resulted in fatalities. The meteorological conditions are examined...
Computational Tools for Subsurface Conceptualization
Development of subsurface conceptual models for use in groundwater flow and transport modeling requires that existing data in the form of boring logs, cone penetrometer (CPT) logs, geophysical...
European Progress on river Renaturalisation
Most restoration projects in Europe have been designed to maximise species richness with little regard for channel stability. To recreate a sustainable natural channel it is necessary...
Ecological and Biological Considerations in River Restoration
When planning river restoration projects, proper consideration must be given to the target resources of concern. This should include provisions to meet the physical, hydraulic, and biological...
Role of Vegetation in Hydraulics of Channel Restoration
Boundary layer theory is used to develop a backwater model for flows through vegetated waterways which can be employed to approximately estimate flow depth variation in channel restoration...
