Arbuckle Mountain Hydro Vertical-Axis Fish Screens
Fish screens to exclude small fry and debris at remote sites such as Arbuckle Mountain Hydroelectric Plant post unique design considerations to satisfy criteria established by fisheris...
Enhancement of Walleye Spawning Habitat Through Flow Regulation
This paper present the results of a study focused on assessing the flow requirements for walleye spawning below a hydroelectric project. The results suggested that both the fishery resource...
Fish Mortality at a New Low-Head Hydroelectric Plant
A study was developed for the Morrow Plant to investigate the potential for turbine related mortality of entrained fish. Morrow Lake supports a small sport fishery, mainly for smallmouth...
Innovative Intake Protects Both Aquatic Life and Turbine Equipment
The successful operation of small hydro projects requires an intake system with the ability to screen fish and debris from the water taken into the turbine. This separation may be required...
Getting to the Root of Sewer Problems
The ability to quantify and qualify work schedule in a clear, logical and precise manner can make the difference between an effective preventive maintenance program and one of 'trying'...
Modeling Pesticide Metabolite Transport with Gleams
The GLEAMS model (Groundwater Loading Effects of Agricultural Management Systems) was modified to simulate the generation and degradation of pesticide metabolites. Translocation of the...
Alfalfa Yield Response to Shallow Groundwater
Operating Criteria for the Newland Project assume that crops grown on bottomlands will use some shallow groundwater as partial fullfillment of evapotranspiration demand. Three years of...
Use of the Penman Equation in Inter-Mountain Valleys
H.L. Penman equation as well as the J.L. Monteith version of this equation were compared under the advective conditions of the Grand Valley of Colorado. The wind function in the general...
Large Scale Evapotranspiration from Remotely Sensed Surface Temperature
Large scale evapotranspiration requires a blend of ground-based and remotely sensed data. To evaluate the utility of the extension from a small to a large scale, studies were conducted...
Pesticide and Nitrate Movement Under Conservation and Conventional Tilled Plots
Carbofuran, alachlor, atrazine, nitrate and bromide (a tracer) were applied to plots with conventional and conservation tillage. During the early part of the growing season the conservation...
Bulk Stomatal Resistance in Operational Estimates of Evapotranspiration
General relationships for estimating canopy or bulk stomatal resistance and aerodynamic resistances of grass and alfalfa reference crops for use in the Penman-J.L. Monteith equation are...
Platte River Irrigation Development: Hydrologic Myths
Several proposed municipal and irrigation developments in Wyoming, Colorado and Nebraska could impact flows along the Platte River in central Nebraska. Opposition to these projects is...
Wetland Replacement?Does It Work?
The consulting firm of CE Maguire, Inc. was contracted by the U. S. Army Corps of Engineers to evaluate the success of 32 wetlands created to replace wetlands destroyed by filling or dredging....
Survival of Seagrass Plugs: Mechanical Harvesting
During the spring of 1985 a mechanical technique for harvesting seagrasses was developed in order to salvage large quantities of seagrass materials that were to be destroyed by a 4. 2...
Guadalupe Dunes Revegetation Program
The subject of this paper is a revegetation program currently being developed by McClelland Engineers and Cities Services for a five-mile pipeline construction corridor in the Guadalupe...
Establishing Native Plant Communities on a Coastal Landfill, Berkeley, California
Three native coastal plant communities were successfully established in a park created on a landfill site on San Francisco Bay: coastal strand, coastal scrub, and prairie grassland. The...
Disturbance and Community Development
This paper reports on the recovery of nearshore vegetation after Hurricane Allen in 1980, change in roadside vegetation throughout a year, and the early re-establishment of vegetation...
Parameters Controlling the Success of Dune Revegetation at King Salmon, California
An eroded 9. 3 ha (23 acre) sand spit was restored through jetty construction and fill (using dredge spoils) by the Corps of Engineers at King Salmon on Humboldt Bay, California. An experimental...
Revegetation in the Arctic (
A tremendous amount of information on revegetation of Arctic tundra was gathered during the following completion of the Trans Alaska Pipeline System. This information and initiation of...
Economic Benefits to Chesapeake Bay Blue Crab Fishermen From Water Pollution Control and Habitat Restoration
Water pollution, primarily by herbicides and nutrients contained in agricultural runoff and in waste treatment plant effluent, appears to be a major cause of the decline in abundance of...
