Modeling of the Undular Jump for White Water Bypass
Two of the authors have reported previously on the hazard that a conventional hydraulic jump with a uniform reverse surface roller presents to white water boaters. The intent is to create...
Scale Model Study Benefits Hydropower Project
The Jim Falls Project on the Chippewa River in Central Wisconsin deals with the replacement of an aged 11 MW run-of-river hydropower plant by a 48 MW peaking plant. A hydraulic model built...
Estimating Probable Storm Damage on Barrier Islands
This paper demonstrates a methodology for estimating probable property damage losses from hurricanes on barrier islands. Using the case study of Gasparilla Island, Florida, it estimates...
Coastal Protection Guidelines, Orange County, GA
As a result of coastal storms in the past several years the County of Orange (California) incurred large and unanticipated costs in providing emergency protection for private shorefront...
Wave Height Distribution in the Coupled Harbor
Wave height in a harbor sheltered by a breakwater is studied by numerical simulation and experiment. The coupled harbor, attained by setting up double arm breakwaters, was adopted as the...
Water Management of the Tenn-Tom Water
In December 1984 the final segments of the Tennessee-Tombigbee Waterway were completed. The Waterway connects the Tennessee River to the Gulf of Mexico at the City of Mobile. The total...
Solving Stormwater Drainage Problems Through an Area Drainage Master Study Program
The Flood Control District of Maricopa County, Arizona, is the floodplain and stormwater management agency for the most densely populated county in the State. A major new tool being used...
Design Storms for Urban Drainage
The characteristics of design storms for urban drainage are reviewed. There are indications that, under certain conditions, design storms produce runoff simulation results which are equivalent...
Characteristics of Intense Storms in Kansas
This paper examines point-rainfall characteristics of intense storms in Kansas. Hourly rainfall records were analyzed for 1006 intense storms selected from some 1800 station-years of data....
Outlet Structure Hydraulics
Current detention basin design procedure is to design the outlet structure for two or more return periods. This is sometimes done by combining weirs and/or orifices of various sizes and...
Air-Water Oxygen Transfer at Spillways and Hydraulic Jumps
Dissolved oxygen measurements are reported for seven spillway structures in the vicinity of Minneapolis, Minnesota, corresponding to 27 individual surveys. The surveys are taken during...
On-Site Microcomputer Control of a Combined Sewer Overflow Diversion Structure
This paper describes the design of an inexpensive system for controlling combined sewer overflows using on-site equipment (raingauges, flow gauges, automatic gates, and microcomputers)....
Computer-Aided Analysis of Treatment Plant Hydraulics
This paper describes software for the hydraulic analysis of water and wastewater treatment works. HADES (the Hydraulic Analysis, Design, and Evaluation System,) provides interactive analysis...
Management Practices for Erosion and Sediment Control in Irrigated Agriculture
Basin irrigating rice can reduce suspended sediment loads in water because the basins serve as sediment retention basins. Furrow erosion causes significant suspended sediment loads in...
Hydraulic Reliability of Urban Water Distribution Systems
Conventional planning and design approaches for urban water distribution systems consist of trial and error procedures to select piping network configurations, pipe sizes, storage capacities...
Modeling Reliability in Water Distribution Network Design
The component failures in a water distribution system include pipe breaks, pump failures, valve failures, storage malfunctions, etc. The reliability of these components has an effect upon...
Model for Optimal-Risk Based Water Distribution Network Design
Various models using a variety of optimization techniques were developed for determining pipe diameters, network layout, pump capacities, and other design parameters. The objective function...
Traveling Trickler Center Pivot Design
There have been a number of proposals to improve the center pivot irrigation system in order to overcome the inherent inefficiency from high evaporation losses and energy requirements....
Intense Storms and the Runoff Coefficient
During prolonged, intense storms the runoff coefficient increases in value and approaches one irrespective of the vegetation and soil characteristics of the watershed. As the runoff coefficient...
Unique Flood and Drainage Problems in Los Angeles
Storm drainage for the coastal cities has to traverse highly used sandy recreational beaches. Due to new requirements on the construction of storm drains to the ocean, a beach outlet has...
