The Effect Of Vegetation, Soil, And Rock Type On Runoff From Some Small Watersheds In Missouri, Anant Suthipas Narupon
The Effect Of Vegetation, Soil, And Rock Type On Runoff From Some Small Watersheds In Missouri, Anant Suthipas Narupon
Masters Theses
"A previous study of mean annual floods (Harbaugh, 1962) was based on watershed area, channel length, and channel slope of forty five small watershed in the State of Missouri. The present study investigates the effect of precipitation, soil distribution, vegetal cover, and underlying bedrock on annual peak rate of discharge. This study consists of statistical analysis by multiple correlations of additional quantitative data for nine of Harbaugh's forty five watersheds. Hydrologic data were obtained from the U.S. Geological Survey and U.S. Weather Bureau climatological publications. Distribution of vegetation was compiled from U.S. Department of Agriculture aerial photographs. Soil and rock …

Maximum Present Value Calculations With Digital Computers, James Boyd Robison
Masters Theses
"This paper discusses maximum present value calculations for a mineral property using digital computers. A semi-quantitative mathematical model to optimize operating conditions is considered. The model is based on a modified cash flow analysis. Many variables affect the solution, and their effect upon present value is described. Selected data (mining rate, costs, reserves, metal sales price, and others) for a hypothetical open pit copper mine are used in a set of solutions for present value. The results are discussed in detail. It is concluded that: (1) Digital computer methods are rapid and useful, (2) Changes in the mining rate, average …
Piezometric Levels And Shallow Aquifers, Dillon And Meramec Spring Quadrangles, Missouri, James Hugh Crouch
Piezometric Levels And Shallow Aquifers, Dillon And Meramec Spring Quadrangles, Missouri, James Hugh Crouch
Masters Theses
"Little is known about groundwater in carbonate rock; quantitative data about limestone and dolomite aquifers are almost non-existent. Objectives of this study are: identification of shallow aquifers, and yield, occurrence, and piezometric level of groundwater in cherty dolomitic rocks in eastern Phelps County, Missouri. Area studied comprises of the 7.5-minute Dillon and Meramec Spring Quadrangles. The data used were derived from water well logs, interviews with well drillers and owners, and a previously available geologic map.
The Jefferson City, Roubidoux, and Gasconade formations are aquifers. Groundwater in the Jefferson City formation is perched. West and north of Dry Fork creek, …
