Sand Management Planning in Oregon
Under Statewide Planning Goal 18 dune grading or sand movement necessary to maintain views or prevent sand inundation is allowed only as part of an area-wide foredune management plan....
Evaluation of Plants for Coastal Dune Stabilization
The dune stabilization system used in the Phoenix Condominiums project can be used to enhance dunes all along the Atlantic and Gulf Coast. The plants and technology are available, which...
The Marine Mammal Health and Stranding Response Program
A National Marine Mammal Tissue Bank (NMMTB) has been established as part of a comprehensive effort to obtain reliable information on contaminant levels in marine mammal tissues. A four...
DUNECARE: Healing the Coast
DUNECARE is active community participation in environmental restoration. This document reports on the operation of the DUNECARE programme in coastal New South Wales, Australia. A Model...
Holding a Shorelind with a Buried Revetment
Two shoreline modification projects were designed that use a new application of an old idea to provide erosion protection and improve shoreline access and aesthetics. The innovation consists...
A Method for Classifying Land Loss by Geomorphology and Process
There is great debate as to the causes of land loss in Louisiana and the restoration/preservation solutions that should be implemented. Much of the controversy can be attributed to a lack...
Bank Erosion at the Aransas National Wildlife Refuge
The Aransas National Wildlife Refuge has been experiencing problems with the erosion along the banks of the Gulf Intracoastal Waterway. In order to prevent future erosion it is necessary...
Wave Boundary Layer Above the Submerged Coastal Slope
A calculation method of parameters of turbulent boundary layer formed by waves is proposed. A calculation of boundary layer on a rough slope with inclination typical for steep Caucasian...
Case Studies for Coastal Protection: Dithmarschen; Eider Estuary; Sylt
Three cases along the Ger North Sea coast, north of the Elbe estuary are discussed. Land reclamation by building dikes started in the Dithmarschen-area almost eight hundred years ago....
Characteristic of the Yellow River Delta
The yellow river delta is a most unstable delta in the world. The river burst its lowstream bank 1500 times during the last 3000 years, 26 large shifting of the channel as well. The river...
The Fraser River Delta, British Columbia: Architecture, Geological Dynamics and Human Impact
The Fraser river delta is the largest delta in western Canada. It is an important coastal ecosystem and an area of explosive urban and industrial growth lying within the most seismically...
The Planning and Design of Multipurpose Artificial Barrier Reefs
Multipurpose artificial barrier reef is proposed for the enhancement of fisheries as part of the purpose of entire system of structures in Japan. As part of our planning efforts we are...
Travel Time in Mountain Basins
An empirical relationship is developed for estimating travel time in high gradient stream channels with natural beds of large gravel, cobbles and random boulders and which are flowing...
The Use of Residence Time to Describe a Hillslope
Queueing theory has been applied to the determination of Soil Water Residence Time (SWRT) using an 18 year data set. The calculated SWRTs agree qualitatively with the lags exhibited by...
Reactive Irrigation Scheduling for Sloping Furrow Irrigation
We developed a technique for estimating the proportion of the applied irrigation water that is effective when using furrow irrigation. To apply the method, irrigators would need to know...
Sediment Entrapment by Stream Channel Vegetation
Degraded headwater streams are common in the mountainous West. They have experienced a variety of stresses from public and private uses and will require specific management consideration...
Primary Metals and Criteria for Water use in the Columbia River, British Columbia
We assessed primarily concentrations of lead, cadmium, copper, zinc and water hardness in the Columbia River between Birchbank and Waneta. Water quality in this reach of the river is affected...
Stable Slopes of Alluvial Channels
An alluvial channel responds to the variation in the incoming sediment by changing its cross-section and especially the slope. Regime relations formulated by Lacey (1930) and many subsequent...
Hourly Reference Evapotranspiration by Bowen Ratio and Penman Methods
Hourly and daily reference evapotranspiration (ETo) computed from Bowen ratio energy balance (BREB) measurements were compared with ETo estimated from the hourly Penman equation (ETP)....
The Influence of Slope and Surface Roughness on Trapezoidal Free Overfall Characteristics
The brink depth-discharge relationship for trapezoidal free overfalls was investigated including the effects of slope and roughness. The theoretical relationship is based on the momentum...
