Applications and Research in Sediment Delivery and Routing Models in the USDA-Forest Service
Sediment delivery and routing are important watershed management issues in the USDA-Forest Service. The relationship between forest management activities and stream morphology, resident...
Limitations of Modeling High Concentration Streams
Following the 1980 eruption of Mount St. Helens, high sediment concentrations caused rapid deposition and increased flood hazards along the Cowlitz River. The Corps of Engineers developed...
Estimation of the Effect of Land Use Changes on Storm-Event Sediment Yield from a Small Watershed
The influence of partial deforestation in a small lowland watershed in the center of Poland on storm-event sediment yield is analysed. Rainfall-runoff model has been applied to estimate...
Sedimentation in Mud Mountain Reservoir at High Discharge
Mud Mountain Dam is a single purpose flood control project completed in 1948 on the White River in the State of Washington. The White River drains the northern and northeastern slopes...
Infiltration of Water to the Ground in a Flood-Control Reservoir with Seepage
As storm water management in urban area with increasing amount of runoff, flood-control reservoir with the bed having large permeability to enrich the groundwater is considered. A dynamical...
Reducing the Potential for Flood Litigation
A flood event is usually followed by numerous damage claims that often lead to litigation. This paper proposes measures to mitigate the potential for litigation. It is stressed that an...
Implementation of FEMA Guidelines on Alluvial Fans
This paper provides a general basis for analysis and mapping of flood hazards on alluvial fans. Federal Emergency Management Administration (FEMA) alluvial fan methodology is discussed...
Predicting Human Instability in Flood Flows
The delineation of high flood hazard zones within a flood plain is usually independent of the parameters that constitute a life threatening situation. In order to define human instability...
Cross Sectional Area Reduction Floodway Method
Encroachment on the floodplain, such as structures and fill, reduces the stream's flood carrying capacity, increases the flood heights and velocities, and increases flood...
Incremental Damage Assessment (IDA) For Lake Darling Dam
An Incremental Damage Assessment (IDA) has been completed for Lake Darling Dam, located on the Souris River, near Minot, North Dakota [1]. The IDA has indicated that a reduction in flood...
Peak Outflow From a Breached Embankment Dam
A relation for rapidly predicting the peak outflow rate from a breached embankment dam has been presented. The prediction equation is based on reliable data from 19 embankment dam failures...
Single-Channel Alluvial Fan Hydraulics with Application to Design of Medium-Density Projects
Methods to identify flood hazards on alluvial fans are provided by the Federal Emergency Management Agency (FEMA) in their Flood Insurance Study, Guidelines and Specifications for Study...
Hydraulic Design of the Unser Boulevard Crossing
As an integral part of the design process, a comprehensive hydrologic, hydraulic and sediment transport analysis was completed of the proposed Unser Boulevard crossing of Calabacillas...
Partnership in Environmental Design for Brush Creek Flood Control
Brush Creek drains a highly urbanized area in metropolitan Kansas City. A large physical model was used to develop a channel modification design for flood control. The Parks and Recreation...
Regional Flood Plain Management
A flood plain management plan for White Rock Creek in the Cities of Dallas and Plano, Texas was developed. New technologies such as three-dimensional topography, CADD, and remote sensing...
Relief of an Urban Storm Drainage System
The Peaks Branch storm sewer system was designed in the 1930s to drain 5.7 square miles of East Dallas. Subsequently, development blocked the emergency overflow paths and many areas are...
Statistical Frequency Analysis of Flood Records
The U.S. Geological Survey, like other Federal agencies, uses Hydrology Subcommittee Bulletin 17 for guidance in statistical frequency analysis of flood records. This paper describes the...
Regionalization of Flood Characteristics
Regionalization procedures are used to transfer flood characteristics from gaged to ungaged locations. These procedures are an extension of the gaging network that allows planners and...
Urban Flood Frequency and Hydrograph Analysis
A set of seven-parameter regression equations was developed for estimating flood discharges at ungaged areas. The regression equations can be used to estimate urban flood discharges throughout...
Plans for National Flood Frequency by Microcomputer
Work is underway on a planned microcomputer program that will include about 1500 prediction equations for 214 flood regions of the United States and Puerto Rico. The program will include...
