Import Substitution Potentials And Marketing Policies For Forest Products In Iran, M. A. Salimi-Manshadi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Consumption data for different forest products were calculated for nine years (1962 to 1970). Then, taking consumption as a function of per capita disposable income and population, mathematical models were developed. By regressing per capita consumption of each product on per capita disposable income and determining the corresponding coefficients, the per capita demand for the products in the target years was calculated. The total projected demand was then computed by the products of per capita consumption and population in the target years.

Through regression analysis the future import of forest products was projected, and import substitution possibilities were discussed.

Hybrid Computer Modeling Of The Hydro-Salinity Flow System Within A River Basin, Duane R. Jensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As demands upon available water supplies increase, there is an accompanying increase in the need to assess the downstream consequences resulting from changes in the upstream hydrologic system and salinity flow system.

Since the burden of water quantity and quality maintenance must be shared by the users, predictions are needed for quantity and quality changes which might result from contemplated development at any specified location within the river system. A close relationship between the hydrologic and salinity flow systems exist, thus making it necessary for an understanding of both systems in order to properly manage the salinity system.

This study …

Model For Predicting Simultaneous Distribution Of Salt And Water In Soils, Satish C. Gupta

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Knowledge of water and salt movement in soils is necessary for development of a management scheme for controlling the quality of irrigation return flow. A computer model was developed to predict the distribution of water and salts in the root zone under varying initial and boundary conditions. The model consists of water flow and salt flow sub-models. The water flow sub-model considers the numerical approximation of the general water flow equation with modification for water loss by evapotranspiration (and thus root extraction). The salt flow sub-model considers the mass flow of salts, chemical exchange, precipitation or dissolution of CaCO_{3 …}

Simulation Of The Dynamics Of Erodible Streams, Kousoum S. Sakhan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The movement of translatory waves over an erodible stream has a critical influence on the time of rise of the hydrograph which, in turn, affects the stability of the stream channel. In the present study, the movement of these flood waves is described by the one-dimensional equations of continuity and motion which are obtained by the space integration of the three-dimensional equation of continuity and Reynolds equations. The flow of suspended sediment is described by a one-dimensional dispersion equation which is derived from a three-dimensional equation of conservation of solid mass in the flow. With some modifications the one-dimensional dispersion …
