Streamflow Losses, Consequent Flow Through a Thick Unsaturated Zone, and Recharge to an Unconfined Aquifer
Two experiments were conducted in conjunction with a 23-day aquifer test made in south-central Arizona to determine (1) water loss from a natural channel and (2) flow through a 330-foot-thick...

Modeling Flow in an Ephemeral Stream Channel
A particularly distinguishing characteristic of ephemeral streamflow is the large role played by infiltration. Infiltration interacts in a complex way with channel flow to control the...

Fishery Mitigation in an Estuarine Environment
This paper summarizes the major features of the estuarine mitigation plan proposed by New York State Department of Transportation in conjunction with the interstate highway project known...

Los Angeles-Long Beach Harbor Complex 2020 Master Plan
The purpose of this plan is to identify and analyze alternatives for the Los Angeles-Long Beach Harbor Complex for dredging deepwater channels and developing new land area that will serve...

Regional Waterfront Planning Without a Superagency: Can Existing Agencies Fill the Gap?
As far back as 1966, the Regional Plan Association saw the potential for mixed use development of underutilized and vacant land along New Jersey's Hudson River Waterfront....

Investigations of Day-Night Distributional Changes of Striped Bass in Hudson River Interpier Areas
As part of a Hudson River fisheries study, investigations were made in an attempt to assess whether onshore-offshore movements could change the number of juvenile striped bass using interpier...

Importance of Underpier Areas in Lower Hudson River for Striped Bass
A stratified random sampling design was employed in which each of three sampling zones (New York, New Jersey and Upper Harbor underpier areas) were sampled once per month from February...

The Use of Thematic Mapper Data for the Identification and Analysis of Small Island Land Covers: The Case of Block Island
This paper describes the classification (unsupervised) of a portion of the Landsat Thematic Mapper (TM) scene covering Block Island, Rhode Island and surrounding waters. The Landsat system...

Coastal Resource Management: The Ecosystem Perspective
A definite need exists to generate coastal management strategies that focus upon integration of the complex interactions between biological, physical, chemical, and geological processes...

Application of Estuarine Habitat Models in Alabama
The development of quantitative impact assessment methods over the past decade has improved our ability to identify environmental losses and recommend appropriate compensation measures...

Community Succession Modeling for Resource Management
The U. S. Fish and Wildlife Service is implementing community succession models to forecast the impacts of altered hydrological regimes on forested floodplains and coastal marshes. A pilot...

Geomorphic Processes and Stability of Coastal Wetlands
Theoretical stability analyses of coastal wetland systems typically show that the key determinant of stability is the rate of operation of geomorphic processes. This implies that if the...

The Suwannee River Estuary: Cohesive Sedimentation
Cohesive sediment dynamics as effected by salinity intrusion are described for the Suwannee River Estuary, a large estuary flowing over the very shallow limestone shelf of Florida's...

Influence of the Drought Phenomenas of the Senegalese Coastal Ecosystems: The Case of the Saloum Estuary and Mangrove Area
The persistent drought, with the strong reduction in freshwater, causes an oversalinity from upstream to downstream in the Saloum waters. The mangrove system operates such as an inverse...

Multidisciplinary Barge Fleeting Site-Evaluation
The U. S. Maritime Administration, in cooperation with the State of Louisiana, recently (March 1985) released a major report on barge fleeting on the Lower Mississippi River. The study...

New Orleans Flood Gates Hydraulic Model Study
A hydraulic model study was conducted to evaluate the forces exerted on selected floodgates by flowing water as the gates are closed after flooding has begun. The results of the study...

Teaching Open Channel Design with Programmable Pocket Calculators
The goal of the basic open channel flow course is to present the theory of steady flow of water in open channels and some channel design practice. This paper presents the evolution of...

Comparing Flood Stage-Discharge Data?Be Careful!
A long term stage-discharge record is extremely valuable data. However, simplified applications of long term records to draw sweeping conclusions about man's effects should be avoided,...

Real-Time Monitoring and Flood Forecasting in Harris County, Texas
A new automated flood warning system is now serving the 2,700,000 residents of Houston, Harris County, Texas. Real-time rainfall and river level data from more than 90 sensors are automatically...

Application of Geographic Information System for Hydrologic Investigation
The Illinois Department of Energy and Natural Resources is developing a geographic information system (GIS) under the federally funded Lands Unsuitable for Mining Program (LUMP). This...
