Bulletin No. 182 - The Net Duty of Water in Sevier Valley

The Sevier River is one of the most important sources of irrigation water in Utah. It rises in two main branches. The south fork rises in Kane County and flows almost due north to Junction in Piute County, where it joins the east fork, which rises partly in Garfield County and partly in Sevier County. The Garfield County branch of the east fork flows north, and the Sevier County Branch flows south to Coyote where the two tributaries join and flow westward into Junction. From Junction, the river flows northward past Marysvale, Sevier, Richfield, Salina, Gunnison, and Mills, where it takes a westerly course to Leamington and from there a southwesterly course past Delta, Oasis, and Deseret, and into the Sevier Lake, part of which lies in Millard and part in Beaver County

Circular No. 39 - A Day at the Utah Agricultural Experiment Station

From the days when Indian chieftains with their hostile bands roamed the sagebrush areas of Utah down to the present, nature\u27s forces have been subdued by many a daring and successful conquest thru the intelligence and unyielding perseverance of Utah\u27s pioneers. Since its establishment, the energies of the Agricultural Experiment Station have been directed toward a continuance of this conquest

Dryland Safflower Response to Dormant Seeding in Utah

The dormant seeding of safflower on dryfarms has shown great potential in northern Utah and southern Idaho, but acceptable weed control is a major concern before this practice can be recommended on a larger commercial scale

Economic Impacts of Farm Program Payment Limits

The high levels of government payments to farmers resulting from the 1985 farm bill have once again led the Congress to examine the payment limit issue. Payment limits were initially established in 1970 and have since been revised several times. In this report, policy and farm management economists analyze the consequences of alternative payment limits on economic efficiency, economic viability of family-size farms, international competitiveness, and consumer food costs. Effective payment limits encourage reduced farm size and in the presence of economies of size, tend to increase production costs for program crops. The Agricultural and Food Policy Center is charged with evaluating economic impacts of policy alternatives -- not recommending, advocating, or opposing particular policies. The Center's orientation is toward Texas agriculture -- evaluating policy impacts on its producers and consumers. Farm prices and income, however, are determined in world markets that are influenced by national economic policy and farm programs. Texas impacts, therefore, must be evaluated in a much broader national and international market and policy context.Agricultural and Food Policy,

Statistical Relationships Between Storm and Urban Watershed Characteristics

Because of the rapid urban development in recent years, hydrologic problems associated with urban watersheds have gained importance. Large sums of money are being spent for the design of urban drainage systems based upon inadequate procedures for predicting peak runoff rates. In this report a procedure is proposed for predicting peak runoff rates from small urban and rural watersheds based upon measurable storm and watersheds characteristics. The technique was tested for a number of runoff events on the Boneyard Creek watershed at Urbana, Illinois, and the results of this test are included. The procedure will be particularly useful for estimating runoff rates from small ungaged drainage areas, and thus will be directly applicable to both design and water management problems

Phase estimation for global defocus correction in optical coherence tomography

In this work we investigate three techniques for estimation of the non-linear phase present due to defocus in optical coherence tomography, and apply them with the angular spectrum method. The techniques are: Least squares fitting the of unwrapped phase of the angular spectrum, iterative optimization, and sub-aperture correlations. The estimated phase of a single en-face image is used to extrapolate the non-linear phase at all depths, which in the end can be used to correct the entire 3-D tomogram, and any other tomogram from the same system
