Stream Flow Model for a Coastal Stream in Egypt
The Coastal region north of Egypt contains many small streams known as Wadis which are considered the main water resources in that region. All the Wadis in the north coast of Egypt run...

Flow Field and Bed Topography in River Meanders
A mathematical model is developed for the calculation of flow field and bed topography in curved channels with an erodible bed. A small perturbation approach is used to linearize the governing...

Processes of Meander Bend Migration
The flow pattern in a meander bend is described in terms of the primary flow, secondary flow, and cross-stream flow. Secondary flow which is normal to the primary flow contributes to lateral...

Flood Event Prediction with Movable Bed Model
This study shows the applicability of using a numerical sedimentation model to analyze various problems related to flood-control design in an alluvial river. Problems concerned with maintaining...

Predicting Channel Recovery from Sand and Gravel Extraction in the Naugatuck River and Adjacent Floodplain
Gravel extraction at five sites along the Naugatuck River in Connecticut is of sufficient magnitude that channel recovery to pre-mining morphology is expected to require up to several...

Friction Factor and Patterns in Armor Coats
Recent observations of friction factors at armor coat forming discharges suggest the presence of distinct geometric patterns in the locations of the coarsest grains in armor coats. A statistical...

Prediction of Scour Depth Under Armoring Conditions
A simple procedure is proposed to compute scour depth on an alluvial bed having graded materials under flow conditions which produce armor layer at the bed surface. The procedure is based...

Twenty Years of Experience in Unsteady Flow Modeling of Open Channels at TVA
Two concerns prompted the development of dynamic methods for flow routings: (a) the safety of the nuclear plants being planned along the Tennessee River in the 1960's and...

A Model of Flow in Regulated Open Channel Networks
A model (NETWORK) is presented for the simulation of unsteady flow in regulated open channel networks. The operation of hydraulic structures, such as gates and weirs, are simulated as...

Physical River Model Results and Prototype Response
The Hydraulics Laboratory of the US Army Engineer Waterways Experiment Station (WES) has performed physical hydraulic model studies on various rivers for nearly 60 years. These studies...

Morphologic and Hydraulic Adjustments of Red River from Shreveport, LA to Fulton, AK, between 1886 and 1980
Morphometric data (channel width and depth and slope) from 4 hydrographic surveys of Red River (1886, 1938, 1968, 1980) from Shreveport to Fulton and specific-gage analyses for the gages...

Hydrologic Forecasting in the National Weather Service
A description of hydrologic forecasting procedures of the National Weather Service (NWS) is presented. Also included is a description of various hydrologic products produced by the NWS...

The Effects of Sediment Transportation Changes on Aquatic Habitat
Sediments are a natural part of the riverine and estuarine environment. However, if the sediment load changes or bed sediment type occur, direct and sometimes detrimental and sometimes...

Sedimentation Problems of the Illinois River Valley
Natural and manmade factors have drastically changed the character of the river and resulted in the accelerated deposition of sediments all along the entire river valley. The Illinois...

Fine Contaminated Sediment Erosion/Deposition in the Buffalo River, New York
This paper documents part of a project which sought to characterize sediment transport in the Buffalo River as a contribution toward planning for dredging or in-place containment of the...

Field Investigation in an Estuary: A Case Study of Cooper River/Charleston Harbor
In 1942, the flow of the Cooper/Ashley/Wando (South Carolina) River complex was altered by a flow diversion project. Subsequently, Charleston Harbor suffered a dramatic increase in maintenance...

Effect of Conowingo Dam Releases on the Water Quality of the Lower Susquehanna River
A modeling study was performed to assess the effects of flow releases from Conowingo Dam on the water quality of Conowingo Pond and the Susquehanna River downstream of the dam. Reservoir...

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...

Performance Evaluation of Channels Stabilized with ARS-Type Low-Drop Structures
Field and hydraulic investigations of seven ARS-type low-drop grade-control structures located in Mississippi indicate that most of the structures become submerged during flows with recurrence...
