A Versatile Methodology for Flood Frequency Analysis
Many observed annual flood series exhibit reverse curvatures when plotted on lognormal probability paper. The occurrence of these curvatures may be attributed to storm and basin factors....
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...
A Possible Definition of the Input Function for a Rainfall-Runoff Model with Lumped Parameters
It may be useful to introduce, instead of a 'mean areal rainfall', another input function, defined as that input which is transformed by the model into a known...
Kinematic, Diffusion and Dynamic Catchment Modeling
This paper reports on a series of tests aimed at developing improved procedures for catchment routing. The objective is to compare kinematic and diffusion models within several scenarios...
A Geomorphologically-Based Runoff Prediction Model: Case Study of Two Gauged Watersheds in Saudi Arabia
Using the Geomorphologic Instantaneous Unit Hydrograph (GIUH) and via the convolution transformation, a linear discharge hydrograph prediction model is obtained. Infiltration in streams...
Overview of a Real-Time Flood Management Model
A flood management model was developed for the operation of the six reservoirs making up the Highland Lakes System on the Colorado River in Texas. The model allows simulation of over 700...
Emerson, Iowa Flood Warning System
A flood warning system was installed in 1985 by the Corps of Engineers at Emerson, Iowa as part of Emerson, Iowa Flood Control Project on Indian Creek. The warning system consists of two...
The Santa Ana River Flood Forecasting System
A real-time flood forecasting and reservoir operations simulation system has been developed for the Santa Ana River Basin, located in southern California. The system consists of generalized...
Denver Area Real Time System
This paper presents a discussion of the development of the Denver Area Real Time System which will be used to regulate the Denver reservoir system on a real-time basis. Its main components...
Groundwater Modeling - A Management Tool
A hydrogeologic investigation within the South Mountain Complex of south central Pennsylvania was performed to develop a groundwater management program. Using LandSat imagery, low altitude...
Effect of Length of Precipitation Record on Recharge Estimates
The effect of the length of precipitation record on groundwater recharge estimates is examined using data from eleven precipitation gages located on the Nevada Test Site. It is concluded...
Well Field Management Designed to Miminize Impact on Surface-Water Flow
Restrictions placed on the operation of a well field used for public water supply initiated an investigation to develop management techniques that would maximize utilization of the well...
Underground Drainage of Urban Runoff from Natural Depressions
A unique subsurface system was designed and implemented for draining such a natural depression in the City of West Lake Hills, Texas. This subsurface drainage system uses a part of the...
Evaluation of Stormwater Management Structures in Maryland Proportioned by SCS TR-55
Various state and local agencies in Maryland are requiring that the Soil Conservation Service Technical Release 55 be used to evaluate impact of urbanization on peak rates of discharge....
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...
Detention Basin Design Using Continuous Simulation
A continuous simulation model is proposed for use in the design of detention basins. The model accepts standard National Weather Service hourly rainfall data as input. The hourly rainfall...
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...
Seasonal Rule Curve Reservoir Operation
This paper addresses the potential for increasing the beneficial use of existing reservoirs in the state of Texas through seasonal rule curve release policies. Seasonally varying operating...
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...
