Density-Dependent Convective Flow In Closed Basins, Kim L. Mccleary

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Great Basin is a region of the Basin and Range Physiographic Province, which is completely isolated hydrologically from the sea. All precipitation that falls within the Great Basin is lost from the land surface or from the surface of closed inland lakes through evapotranspiration. Playas are often found at the base of these undrained basins. This study focuses on subsurface groundwater flow patterns in closed basins. Because all discharge from the basins occurs via evapotranspiration on and near the playa, the water table of the aquifer beneath the playa is often just below the ground surface. Fluctuations of the …

Automatic Meshing Of Free-Form Deformation Solids, Ssuta S. Hsu

Theses and Dissertations

Development of computer models and subsequent finite element analysis, are important aspects of modern engineering design. In this process, the geometry creation and finite element analysis software are well developed; however, the process of discretizing a geometry into a proper finite element model is time consuming and tedious. The work presented here uses the free-form deformation method to create smooth solid models, and invokes a solid subdivision and transition method to generate the hexahedron finite elements. The combination of these two techniques provides an automatic mesh generator that is easy to use, creates acceptable hexahedron elements for finite element analysis, …

An Experimental Study Of Dewatering Of Alum Sludge, Uday G. Kelkar

Civil & Environmental Engineering Theses & Dissertations

The use of aluminum sulfate (Alum) as a coagulant for treating surface water was introduced in 1884. When this salt is added to water, the aluminum Ion hydrolyzes by reaction that consumes alkalinity in water. The gelatinous hydroxide thus formed in the reaction, carries suspended material with it as it settles. In addition, however, it is likely that positively charged hydroxyl-bridge dimmers and higher polymers are formed which interact specifically with the colloidal particles, bringing about coagulation. These gelatinous floes settle by gravity, called sludge, consists of relatively large quantities of suspended and colloidal inorganic and organic materials.

Computational Aspects Of Chance-Constrained Sustained Groundwater Yield Management, R. R.A. Cantiller, Richard C. Peralta

Civil and Environmental Engineering Faculty Publications

A methodology for including chance-constraints in models for maximizing regional sustained-yield groundwater extraction is presented. The procedure utilizes the spatially distributed mean and variance of saturated thickness in a confined aquifer. This data is derivable from kriging, a geostatistical technique. The technique is applied to a scenario of somewhat egalitarian agricultural development dependent on groundwater. Decision makers in this situation know that groundwater availability is insufficient to supply all potential demand. They plan to implement a sustained yield groundwater extraction strategy. They know that because of uncertain knowledge of aquifer parameters, at some point in the future, available groundwater in …

Stress Interference In A Transversely Isotropic Body Under Axisymmetric Loading, Stephen M. Heinrich, J. Y. Wang

Civil and Environmental Engineering Faculty Research and Publications

An unbounded homogeneous transversely isotropic body of revolution containing two twin spheroidal cavities is subjected to an axisymmetric loading. The axis of loading symmetry coincides with the axis of elastic symmetry of the material and the axis of revolution of the body. The elasticity solution is obtained in series form utilizing the displacement potential representation for the equilibrium of transversely isotropic solids, and numerical results are presented for the cases of two spherical cavities perturbing uniaxial and hydrostatic tension fields in certain hexagonal crystals and in isotropic materials. Of primary interest is the influence of cavity spacing and material type …

Traffic Signing For Local Areas, Herpicc

Indiana Local Technical Assistance Program (LTAP) Publications

One of the most important responsibilities of local street and highway departments is to provide the driving public with adequate, appropriate signs to permit safe travel over unfamiliar roads. Unfortunately, this responsibility is frequently neglected or, at best, under-emphasized. The most common excuse used to justify this neglect is inadequate funding, which is undoubtedly true. What is equally true, however, is that resurfacing roads and streets is more politically popular than re-signing them, even though resurfacing leads to increased speeds, which in turn can lead to increased accident experience on improperly or inadequately signed facilities.

This brief report is not …
