Design of Seepage Fields for Stormwater Disposal
Stricker Pond is a shallow twenty-acre kettle hole pond in south-central Wisconsin. The pond receives runoff from a closed watershed that is rapidly undergoing low density residential...
Site Hydrology and Basin Design Using Spreadsheets
The Soil Cover Complex Method which was developed by the Soil Conservation Service is a commonly accepted method of evaluating site hydrology. The solution of this method is facilitated...
Micro-Illudas for Urban Drainage Design
The Illinois Urban Drainage Area Simulator (ILLUDAS) was developed at the Illinois State Water Survey in 1969 and has been available for use on mainframe computers since 1974. An enhanced...
Seepage/Drainage Investigation Colusa County California
High groundwater in the late winter months saturates the soil profile, causing damage to both crops and soil. Sustained water logging severely damages or destroys orchards. It has generally...
Confidence Intervals for Flood Control Design
The line drawn and labeled as the flood frequency curve is seldom identified as to what confidence is associated to the plot. For example while flood control designs are typically based...
Comparison of Hydrograph Simulation Techniques Used in Structural Design and Watershed Systems Modeling
This paper describes a basin study in which traditional unit hydrograph analysis methods were compared to the E. J. Inman hydrograph technique. Study results indicate that, where suitable...
Design Criteria for Detention Basins in Urban Drainage
Many communities require the use of detention basins in order to manage the increased runoff discharge in all newly developing watersheds. The authors have shown earlier that the typical...
The Storage Matching Technique of Detention Basin Design
In recent years, use of continuous rainfall - runoff simulation with historic rainfall data has become much more popular for the design of detention basins and reservoirs. While it may...
Hydraulics of Enlarging Cannonsville Reservoir
This paper describes the hydraulic studies performed for enlarging the Cannonsville Reservoir with a gate system which could raise the normal storage level without having an adverse effect...
An Application of EPA EXTRAN Model to a Flood Management Study in South Florida
In performing the flood management studies, somewhat unique concerns in South Florida are the backwater conditions due to tidal or non-tidal tailwater, flow reversals from project canal...
A Real-Time Flood Management Model for River-Reservoir Systems
A flood forecasting model has been developed for the Lower Colorado River Authority that can be used in a real-time framework to make decisions on reservoir operations during flooding....
Criteria for Spillway Design Floods
The procedures outlined in this paper only address the hydrologic safety criteria for spillway design floods. The recommended procedures are based on a careful identification of the social,...
Indemnification Costs in the Dam Safety Decision
The ASCE Task Committee on Spillway Design Floods has proposed safety criteria for three categories of dams. Category 1 dams are those with anticipated failure consequences so large and...
Safety Design Flood for Too Wide Creek Dam
This paper presents an example application of the procedure developed by the ASCE Task Committee on Spillway Design Floods for a dam on the Too Wide Creek. The example was developed from...
The Dallas Floodway Project
This paper explores the history of the Dallas Floodway project, past performance of the project under various flood conditions, recently updated hydrologic and hydraulic evaluations, and...
Monte Carlo Approach to Spillway Design Floods
This paper shows the use of a daily stochastic streamflow model for the calculation of the hydrograph for spillway design. Most of the literature related to the topic deals with the problem...
An Analysis and Comparison of Probable Maximum Floods with 10,000-year Frequency Floods and Maximum Observed Floods for Spillway Design
The use of deterministic probable maximum floods are supported in part by the conclusions of an Interagency Work Group formed to address the following questions: (1) Is it within the state...
Fault-Tolerant Design for Data Acquisition and Flood Forecast Systems
An innovative fault tolerant flood warning system is currently being installed in the Passaic River Basin. The new system is designed to automatically tolerate the failure of major components...
High Strength Concrete - A New Material
In this paper, the material properties and structural member behavior of normal and high-strength concretes are summarized. The current ACI code recommendations are based on results of...
Structural Considerations of Cellular Concrete
Although not normally considered to be a structural material, cellular concrete possesses characteristics which may result in its having structural applications in building and structural...
