Relation of the drying rate of grain in a continuous counterflow column to the exposed drying rate

Creator:: Laksanakorn, Wichai
Resource Type:: Masters Thesis

Relationships between degree of ponding and uniformity of soil moisture distribution under irrigation sprinklers

Creator:: Dehlinger, Charles Robert
Abstract:: Often low intake rate soils need special consideration when applying water during an irrigation. Surface flooding for extended periods may cause adverse crop growth conditions. Properly designed sprinkler systems often eliminate irrigation problems, because the application rate and quantity of water applied can be readily controlled. Research workers who have...

Bacteria die-off in stream sediments

Creator:: Sherer, Brett Micheal
Abstract:: The purpose of this study was to evaluate the impact sediment has on the survival of bacteria in a typical rangeland stream. This information is an important component in determining a time integrated prediction of bacterial numbers in the stream sediment and overlying water. Bacterial survival in stream is a...

Modeling of point rainfall processes in the Republic of Cape Verde

Creator:: Lenhart, James H.
Abstract:: The rainfall regime of the Cape Verde Islands is influenced by the Intertropical Convergence Zone (ITCZ) resulting in strong seasonal trends and frequent thunderstorm events. These events are frequently responsible for the destruction of riverine structures and valuable crop land. A menu driven database program (RIS) was developed for the...

A model to predict the bacterial quality of a rangeland stream

Creator:: Biskie, Howard A
Abstract:: Grazing cattle usually have access to streams as a source of drinking water. A model was developed for the personal computer to predict the bacterial quality of these streams. The model estimates the number of organisms that enter the stream by the direct deposit of feces and by runoff from...

Practical two-stage pipe expansions for centrifugal pump irrigation

Creator:: Fazio, John A
Abstract:: Centrifugal irrigation pumps discharge fluids at high velocities that must be slowed to minimize energy losses due to friction. Pipe expansions make the transition to larger pipes associated with slower velocities. Expansions convert the upstream velocity head to static head in the downstream pipe. The transition to a larger pipe...

Application of the Penman Equation to central Tunisia

Creator:: Abdelli, Smida
Abstract:: Four years of daily weather observations from Central Tunisia were available for testing the application of the Penman Equation to estimate reference evapotranspiration in the arid climate of Central Tunisia. The data included minimum and maximum temperature, minimum and maximum relative humidity, 24-hour wind run, and lysimeter measurements of reference...
