Model For Estimating Soil Water Flow, Water Content, Evapotranspiration And Root Extraction, Musa N. Nimah

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A mathematical model was developed to predict water content profiles, evapotranspiration, water flow from or to the water table, root extraction and root water potential at the surface as functions of time under unsteady state conditions.

The model was tested in the field at The Hullinger Farm near Vernal, Utah, in 1970 and 1971. Comparison of water content-depth profiles show excellent agreement at the end of a 9- day run in 1970 on oats seeded to alfalfa. In 1971 with alfalfa as the crop, the data show best agreement, between predicted and computed water content-depth profiles, 48 hours after any …

Role Of Transition Metals In Nitrite Decomposition In Soil, J. S. Bajwa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Iron and copper increased the decomposition of nitrite significantly during the first two hours of reaction when 150 parts per million (ppm) of nitrite and nitrogen was added to an acidic soil. Manganese was found to have a slight effect. There was no additional effect of the added metals after two hours reaction time.

The higher concentration of metals was not effective in catalyzing the decomposition of the added nitrite in nitrogen. All the added nitrite nitrogen was not recovered and the deficit could be due to the formation of nitrogen gas.

A Functional Analysis Of The Naval Weather Service System, Charles P. Pfarrer Jr.

Theses and Major Papers

The purpose of this paper is to analyze the Naval Weather Service system by defining its functions; for the available literature does not convey the concept of interacting elements contributing to the operation of the larger whole. This paper concentrates on articulating the contributions of the related actions to the Naval Weather Service system. The aim is for clarity of exposition. The purpose is to get across the big picture. Int introspective format ensues formally from the rational foundations of the conceptual mode of inquiry. This paper addresses the Naval Weather Service system and not the scientific and technological process …

A Synoptic Air Mass Climatology Of The Eastern United States, Robert I. Wittick

Masters Theses

Chapter I

Introduction

Orientation and Objective

The concept of the air mass was developed by a group of Norwegian meteorologists during World War I. An air mass, they said, was a body of air which was horizontally homogeneous with respect to temperature and humidity. These bodies of air were classified according to their place of origin since the basic character of an air mass is similar to that of its source region.

Since 1932 when the first air mass climatology was written by Dinies¹, the meteorological and geographical journals have published many studies of air mass movements and …

Temperature Conditions At Orono, Maine, Ernest Claude Drew

Electronic Theses and Dissertations

This thesis is an outgrowth of a much larger piece of work which the Department of Physics, thru its instructors and major students, has undertaken to complete. The task referred to, is the compilation, arrangement, and summarizing of the various meteorological records taken at the University of Maine for the past forty-four years. These records were begun in the above department by Dr. M. C. Fernald in the year 1869 and were continued by him until 1893. The work was then transferred to the Experiment Station, where observations were made under the direction of Doctors W. H. Jordan and C. …
