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...
Mixed Solute Interactions in Groundwater Systems
Research results are presented from a study examining the competitive sorption effects of two organic chemicals, para-dichlorobenzene and 2,4-dichlorophenol, to solids from the Cohansey...
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)....
Water Erosion from Irrigation?An Overview
Erosion and sedimentation by water includes the process of detachment, movement, and deposition of soil particles (14). Under irrigated conditions, the erosive process is water flowing...
Effects of Erosion on Soil Productivity
Erosion-caused crop production decreases up to 50% have been measured with decreases of 15 to 30% commonly reported. Furrow erosion on irrigated land redistributes topsoil, decreasing...
Erosion and Sedimentation Processes in Irrigation
Soil erosion occurs when fluid in motion detaches and transports soil particles. Sedimentation occurs when the fluid transport capacity decreases. Both the hydraulic forces of moving water...
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...
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...
Ground Water Pollution Potential from Irrigation?Eastern United States
The purpose of this paper is to present an evaluation method for determining the influence irrigation of agricultural land has on regional ground water quality. It integrates data on irrigation...
Integrated Wastewater and Sludge Treatment in a Tree Farm
A system which integrates land treatment of wastewater following primary sedimentation with tree production and sludge composting was evaluated for its land requirements, costs, and energy...
Computer Aided River Basin Management in the Alps
The present paper outlines progress in developing river basin management potential through joint research on several Alpine River Systems including the Avisio, Brenta, and Cordevole. Applications...
Interactive simulation of Water Resource Systems
This paper outlines some of the research currently underway at Cornell aimed at the design of an interactive simulation methododology. It describes the general approach to simulation modeling,...
Response of the Citanduy River to Developments
The sinuous alluvial reach of the Citanduy River in Java, Indonesia has been surprisingly stable in spite of man-made cutoffs which have reduced the channel length from 98. 7 km to 78....
Converting a Mainframe Erosion Simulation Model to a Microcomputer Software
In this paper, techniques for mainframe to micro conversion are discussed. As a practical case, an erosion simulation model was used. The created software predicts distribution of erosion...
Evaluation of PCP/Oil Spill on CFT Indian Reservation Near Nespelem, Washington
This paper presents the immediate action taken, the field work performed, and the engineering analysis performed in response to a spillage of a solution of pentachlorophenol (PCP) and...
A Computer Program Simulation of the Effect of Upstream Agricultural Practices on the Survival of Salmonid Embryos
A physical-process based computer program was developed to quantify the cause and effect relationship between the survival of salmonid embryo and upstream agricultural practices. The impact...
Ecological Impacts of Sediment Transport to Tropical Reservoirs
Sediment transport and siltation influence both the longevity and ecology of tropical reservoirs. The sediment load to these systems is typically seasonal and affects ecological processes...
