Testing and Effectiveness of a New Urban BMP Stormceptor?*
Stormwater management for water quality control, pollution prevention and pretreatment can be a difficult problem for the development design professional, a costly and time consuming problem...

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...

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...

Channel Junction Effects in Channel Network Flow Simulation
In this paper, the momentum equations, which are applicable at channel junctions, are suggested based on the conservation of momentum flux. In the equation, the lateral inflow angles are...

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....

Modeling the Ecological Impacts of Flaming Gorge Dam Operations
Hydropower operations at Flaming Gorge Dam on the Green River in Utah, U.S.A., can produce rapid downstream changes in flow and stage during a day. These changes can, in turn, affect ecological...

Flood Control in the Brazilian Electric System Reservoirs at Parana River Basin
This paper describes the experience of the Brazilian Electric System in flood control at Parana River basin, and presents the factors that required the consideration of flood impacts in...

Applicability of Scour Equations in Tidal Areas
Bridge scour and waterway instability in the coastal region where waterways are subjected to tidal flow can be subjected to mass density stratification, water salinity, sedimentation (littoral...

Rainfall-Runoff Modeling for Watershed Stormwater Management
In the design of watershed stormwater management plans used for land development, the Pennsylvania State Runoff Model (PSRM) presents upstream subbasin flows that contribute to the peak...

Expected Moments Alogrithms for Flood Frequency Analysis
The Expected Moments Algorithm (EMA) is a new but conceptually simple approach for the treatment of nontraditional data in flood frequency analysis. Nontraditional data includes censored...

Scour around Exposed Pile Foundations
Laboratory experiments were conducted to measure local scour around exposed pile groups for a variety of conditions including different spacings, different skew angles, different patterns...

Discussions of a 3D Numerical Simulation of Transient Regional Groundwater Flow and Transport
A 3D numerical model of a groundwater flow and transport was developed to study the movement of radionuclides in the Savannah River Nuclear Site, South Carolina. The modeling effort has...

Mexican Border Ground Water Agreement
This paper provides a discussion about the challenges in developing a Mexican Botder Ground Water Agreement for the management of shallow ground waters that connect to the surface water...

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...

Portable Flumes with Adjustable Throats
Vertically adjustable flumes for canal flow measurements address several problems in field practice. One involves the perception by some canal water users that flumes and weirs always...

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...

Numerical Modeling of Water Flow over Porous Media
The momentum transport phenomena at the interface of porous media and fluid are numerically investigated. The single domain approach is used with matching boundary conditions; i.e., the...

Glacier-Generated Floods and Debris Flows
Sudden release of glacially impounded water causes catastrophic floods, known as outburst floods, and ocasionally spawn debris flows that pose significant hazards in mountainous areas....

Application of an Optical Monitor in Automatic Control of Coagulation Dosing in Water Treatment Operations
The feasibility of applying an optical monitor in the automatic control of coagulation was assessed in this study. Prior to simulation testing, a series of batch tests was performed to...
