Sediment Variability Mark Twain Lake, Missouri
This paper looks at the historical variability in suspended sediment loads in the Upper Salt River Basin above Mark Twain Lake, Missouri in an attempt to assess the magnitude of suspended...
Martins Fork Reservoir Sedimentation Study
The Martins Fork Reservoir is located on Martins Fork of the Cumberland River in Harlan County, Kentucky. The lake was impounded in December, 1978. Since closure, the lake has experienced...
Discharge Characteristics of Rectangular Profiled Weirs
This paper contains the results of a detailed experimental program carried out to define the discharge characteristics of rectangular profiled weirs. The flow region where the discharge...
Modeling Side-Weir Diversions for Flood Control
Side-channel weirs can be used for diversion to reduce flood peaks. This study has developed a means for incorporating the effects of side weirs in HEC-1 and HEC-2 calculations through...
Measurement and Analysis of Tracfcfifc-Induced Transient Motion in Navigation Channels
Two-induced physical effects related to navigation changes on the Kanawha River, West Virginia were measured at three environmentally sensitive representative locations. The purpose of...
Unsteady Flow in a Navigation Channel
Based on the de St Venant equations, the Preissmann's implicit finite difference scheme, and the double sweep algorithm, a mathematical model for one-dimensional unsteady...
Expert System for Mixing Zone Analysis of Aqueous Discharges (CORMIX1): Further Developments
Two recent publications have reported the development of the Cornell Mixing Zone Expert System (CORMIX) for the analysis, prediction and design of aqueous toxic or conventional pollutant...
Longitudinal Dispersion in Rivers: A Dead Zone Model Solution
The longitudinal dispersion of tracer material in rivers is often analyzed based on the one-dimensional convective diffusion equation developed by G.I. Taylor. However, the persistent...
Discharge Measurement by Thermal Dilution
A flume study was conducted to develop and improve the thermal dilution method of discharge measurement in trapezodial channels. The study was performed in an indoor channel with dischages...
Freshwater Flow from Caves at Chankanaab Park, Cozumel, Quintana Roo, Mexico
The freshwater forms a lense on top of the ocean water and discharges to the ocean through solution channels. One such solution channel is present in Chankanaab Park and is identified...
Measurements of Mean Velocity, Turbulence and Temperature in a Deflected, Heated Water Jet
A submerged heated water jet issuing from a vertical wall into a turbulent flow in a rectangular open channel is investigated experimentally to determine the mean velocity, turbulence...
Silt Run Effectiveness in Withdrawing Sediment
An investigation was conducted during the silt runs on the North Platte River to determine the continued effectiveness of the runs in providing fine sediments to the canal systems downstream....
Reservoir Sediment Sluicing?Laboratory Study
Experiments are being conducted in a 12.2 meter long, 0.38 meter high, 15 centimeter wide flume to examine the behavior of reservoir sediment deposits in response to sluicing. Crushed...
Gas Transfer at the Water Surface: Measurements of Gas Concentration Fluctuations
The paper describes measurements of fluctuating gas (oxygen) concentrations by means of a polarographic microscope near the air-water interface. The objective is to demonstrate the feasibility...
Hydraulic Effects on Swimming Fish in Fish Passage Structures
The implications of profile drag, weight, and buoyant forces on energy and power requirements of fish swimming through fish passage structures are considered. Where hydraulic grade lines...
Flow Through Fish Bypass Intakes
Hydraulic and computational fluid dynamic models were used to investigate the cause of the unequal intake flow distribution observed entering the three vertical intakes of the patented...
Task Committee Report on Reliability Analysis of Water Distribution Systems
The results of the ASCE Hydraulics Division Task Committee on Reliability Analysis of Water Distribution Systems are summarized in a very comprehensive report entitled Reliability Analysis...
New Methodology for Determining the Optimal Rehabilitation and Replacement of Water Distribution System Components
A methodology is presented for the determination of the optimal timing for the rehabilitation/replacement of water distribution system components in order to minimize costs. In this model...
Submerged Flow in Parshall Flumes
Recent data collected in a 1-foot Parshall flume located in the Bureau of Reclamation's hydraulic laboratory indicate a significant discontinuity in the discharge/submergence...
