Are Landscape Patterns Related to Marsh Loss Processes?
Marsh loss that occurs in Louisiana is seldom associated with shoreline erosion of lakes and bayous; instead, marshes break up internally. Marsh loss is attributed to processes that stress...

Consolidation Settlement Potential in South Louisiana
Primary consolidation is an important cause of wetland loss in active and recently abandoned deltaic plains in south Louisiana. Argillaceous and organic facies are most subject to reduction...

Dealing with TMDLs in the Dairy-McKay HUA
The maximum phosphorus concentration for the TMDL in the Tualatin River is set by Oregon Administrative Rules (OAR) at 0.07 mg/1, Dairy-McKay Creek is 0.045 mg/1 Identification of potential...

Marina Facilities Planning Design and Operations in Hurricane Prone Areas
The overall growth in population of coastal areas in the southeastern and coastal regions of the Unites States has created a need for additional water related recreation facilities such...

Anthropogenic Activities Affecting Sediment Load Balance Along the West African Coastline
The west African coastline stretches from Senegal in the west-to Cameroon in the east. This coastline had naturally over time received most of its sediments through the numerous rivers...

Fish Resources of Coastal Waters of the Gulf of Guinea: Natural and Man-Made Factors Influencing their Distribution, Abundance and Capacity for Development and Sustained Exploitation
The Gulf of Guinea corresponding to Equatorial West Africa is bordered by eleven coastal states from Cote d'Ivoire in the west to Gabon in the South. Its coastal waters have no less than...

Lag Relations for Semi-Arid Regions and Urban Areas
The use of synthetic unit hydrographs often requires the estimation of lag or other travel time parameters. Several procedures are available for estimating such unit hydrograph parameters....

Infiltration into Thick Unsaturated Alluvial Deposits: A Preliminary Study
An infiltration and dye transport study in an unsaturated alluvial deposit was conducted using a square flooding type infiltrometer over a 50 hour period. Red and blue dyes were added...

Lessons from Hurricane Andrew's Effects on Hydraulic Structures
Documentation and description of Andrew's effects on open channels and other hydraulic structures in South Dade County, Florida, are presented, based on observations made during field...

Dam-Break Study for Large Floodplain Area - A Case Study
In simulating a dam break flood in a large floodplain, the maximum flood level is sensitive to the off-channel storage volume used in the channel routing. An incorrect estimate of the...

Overland Flow Resistance Estimation from Small-Plot Data
The correct application of physical process models, such as the kinetic wave approximation to shallow overland flow, is dependent upon selection of appropriate values for parameters which...

Short-Span Bridge Solutions
Large bridges get most of the headlines, but the nation's huge network of small bridges (many with spans of less than 25 ft) may be more in need of replacement. Age, corrosion,...

Sediment Yields from a Watershed in Taiwan
Characteristics of suspended sediment load were investigated for Shih-Men Reservoir watershed in Taiwan. Results of the investigation showed that annual suspended sediment load was correlated...

Reducing the Potential Downstream Impacts of a Dam Failure
The dam safety regulations imposed by the individual states in the United States vary widely and provide inconsistent protection for the citizens of different states. The proximity of...

Disaster Reduction in Dam and Reservoir Design
Disaster reduction for small- and medium-sized reservoir projects is considered for two specific types of dam failure: 1) during extremely high floods, and 2) when severe reservoir silting...

Total Sediment Loads of Tropical Rivers
Unmeasured and total sediment discharges were computed for 107 sets of data from the Amazon and Orinoco Rivers and their major tributaries. Unmeasured loads were generally small except...

Development of the Lake Okeechobee Watershed Phosphorus Transport Model
The Lake Okeechobee watershed phosphorus model was developed to route flows and phosphorus loadings associated with point and nonpoint sources through a watershed transport system, and...

Uncertainties of Tailwater in an Inundation Study: Dam Upgrade Optimization for Hazard Reduction
When an upgrade is required for a dam with an inadequate spillway system, the potential impact of tailwater during an extreme storm in an inundation study should be considered. This paper...

Dam Safety Modifications for Clear Creek Dam Manuscript for ASCE Hydraulics Division 1993 National Conference on Hydraulic Engineering
Clear Creek Dam, an unsafe thin arch dam, was stabilized by constructing a concrete gravity buttress on the downstream face. During the Bureau of Reclamation's (Reclamation) Safety Evaluation...

Screening of Bridges in New Jersey for Scour
New Jersey Department of Transportation has embarked on a program to evaluate all existing bridges over waterways to assess their vulnerability to failure by scour. The Stage I (Screening...
