Economics of Ditch Maintenance in Northwestern Ohio
A history of drainage and settlement in the Black Swamp of Northwestern Ohio is presented. The Ohio Ditch Law and county ditch maintenance program is explained. An economic comparison...
Hydrologic Impacts of Improved Irrigation Efficiencies
The Salt River drainage basin (Star Valley) is an agricultural watershed of 829 mi**2 (2150 km**2) in western Wyoming. Salt River stream flows were hydrologically analyzed and a comparison...
Appropriated Water Rights in Utah
The appropriated water rights system used in Utah is discussed. The historical background for establishing this allocation process is reviewed. The process of changing the location and...
Water Requirements of Mountain Meadow Vegetation
Measurements to define agricultural water consumption have been taken in the Green River Basin of Wyoming throughout the summers of 1983 and 1984. The weekly measurements included water...
Effect of Santa Rosa Lake on Ground Water Flow to the Pecos River, New Mexico
In 1980, Santa Rosa Dam began impounding water on the Pecos River about 7 miles (11 kilometers) north of Santa Rosa, New Mexico, to provide flood control and storage for irrigation. Santa...
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...
Innovative Management in a Period of Austerity: The Glamorgan Heritage Cost Experience in the U.K.
Restraint in UK economic growth gave rise to a new countryside management approach which was non-statutory, dependent upon voluntary agreements. In essence the land remains in private...
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...
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...
Implementing Mitigation Policies in San Francisco Bay: A Critique
This paper documents and evaluates 58 permits in San Francisco Bay that required the implementation of wetland restoration projects to fulfil mitigation requirements. The 58 projects are...
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...
Special Management Area Planning in Mississippi's Coastal Zone: The Port Bienville Experience
In Mississippi, the key state agency charged with the responsibility for coastal wetland protection is the Bureau of Marine Resources, a sub-division of the Department of Wildlife Conservation....
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...
