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...
Effects of Saline Water Tables on Corn Irrigation
Hydraulic, weighing lysimeters were used for three years to measure the effect of high, saline water tables on irrigation requirement of corn. For each of the years corn was grown with...
Picture Index for Field Verification of Crop Coefficients
A picture index has been developed for eight irrigation crops to obtain reliable, rapid, and low-cost field determinations of crop growth stages and corresponding crop coefficient (Kc)...
Irrigation Water Requirements Under Wide-Spaced Furrow Irrigation
Research has shown that wide-spaced furrow irrigation (WSFI) can produce acceptable yields of crops with less water than every-furrow irrigation (EFI). In many seasons WSFI will result...
Water Losses from an Irrigation Canal-Ditch-Dugout System
The general limitations of and requirements for accurate determination of water losses from an irrigation distribution system have been identified. A hydrologic water balance technique...
Scheduling in Manually Controlled Canal Irrigation Delivery Systems
The effects of canal transients on scheduling water delivery to an irrigated area are described using a linearized form of flow equation obtained from a zero-inertia momentum equation...
Daily Weather Forecasts Used to Manage Soil-Water
This paper describes a newly developed method for analyzing the rainfall probability data included in daily weather forecasts issued by the National Weather Service. The purpose is to...

Monitoring Completed Coastal Projects
In the United States, construction of public works to develop water resources is the responsibility of the Army Corps of Engineers. These works include projects to improve ocean and coastal...
After Action Report 1983 California Coastal Storms
The winter of 1982-1983 saw some dramatic changes in the worldwide weather patterns that have been attributed to the anomaly known as El Nino. During that winter California was attacked...
The Analysis of the Environmental Impact
Oil serves mankind. Winning such a valuable and necessary energy resource demands for stringent rules. It is not the oil which threatens the environment on earth, but the negligence of...
Oil Spill Risk Assessment for Marine Vessels
An oil spill risk assessment study should show the estimated relationship between the magnitude of an adverse environmental impact and the probability of equaling or exceeding that impact....
Harbor Management a Cooperative Effort in Connecticut
Connecticut Legislature passed an Act concerning harbor management which enables coastal communities to establish harbor management committees and prepare harbor management plans. This...
Statewide Port Assessment?Louisiana Case
The Louisiana Statewide Ports Assessment (LSPA) has been conducted of significant changes in the economic environment of the State, Nation and world, which influences not only trade patterns...
Coastal Management Problems in the United Kingdom
Five case-studies from the East coast of England illustrate some of the obstacles facing more enlightened coastal management in the United Kingdom. All the examples demonstrate unsatisfactory...
Principles for Coastal Zone Management in South Africa
The southern tip of the African continent is characterized by a wide variety of coastal environmental conditions, ranging from a steeply tilted topography with sub-tropical summer rainfall...
Prior Planning for Post-Hurricane Reconstruction
Planning for hurricane emergencies has focused upon the period immediately before and after the storm's arrival, emphasizing evacuation and disaster relief. Mitigation of...
Survival of Ocean Life: The Critical Balance
Several major problem areas in ocean management are in need of immediate and stringent address. Excessive erosion and sedimentation, stems from man's inadequacies in land...
Sand Rights A Legal System to Protect The Shores of the Beach
The legal system of water rights in California is highly developed. So far, however, it has failed to recognize in any comprehensive fashion the importance of the sand which is transported...
Examples of Sediment Distribution in the Italian Adriatic Coast. A Comparison Between the Shepard and the Nota Textural Classifications
