Monitoring Petroleum Contamination in an Aquifer
An experimental study of the behavior of petroleum in an aquifer with static and changing water depths were studied. The experimental apparatus consisted of plexiglass tanks filled with...
HEC River Analysis System (HEC-RAS)
The Hydrologic Engineering Center (HEC) is developing next generation software for one-dimensional river hydraulics. The HEC-RAS River Analysis System (HEC, 1994) is intended to be the...
Using the Weir Back as an Energy Dissipator
The effect of weir back in energy dissipation is investigated experimentally and theoretically. The study includes four different shapes of weir back. The boundary friction force and the...
Improved Hydraulic Features of the HEC River Analysis (HEC-RAS)
The Hydrologic Engineering Center (HEC) is in the process of developing a Next Generation (NexGen) of hydrologic engineering software. The goal in the area of river hydraulics is to develop...
Energy Dissipation for a RCC Stepped Spillway
A two-dimensional physical model study was used to quantify the kinetic energy dissipation of the steps in a roller compacted concrete (RCC) stepped spillway. The steps were effective...
Force and Pressure Measurements in Spillway Plunge Pools
Plunge pools are often used to dissipate energy from high head spillways with flip bucket terminal structures. Conventional design of plunge pools has been based on a program of mobile...
Problems with Indirect Determinations of Peak Streamflows in Steep, Desert Stream Channels
Many peak streamflow values used in flood analyses for desert areas are derived using the Manning equation. Data used in the equation are collected after the flow has subsided, and peak...
An Approach to the Calculation Method of Mean Sediment Size
Mean sediment size is an important parameter expressing the characteristics of sediment. Several calculation methods of mean sediment size which are popular at present almost have some...
Salinity and Dissolved-Oxygen Dynamics in a Wind-Driven Estuary
Water levels, near-surface and near-bottom salinities, and near-surface and near-bottom dissolved-oxygen concentrations were measured continuously in the Pamlico River estuary, North Carolina,...
