Risk Assessment Model For Pipe Rehabilitation And Replacement In A Water Distribution System, Jan C. Devera Aug 2013

Risk Assessment Model For Pipe Rehabilitation And Replacement In A Water Distribution System, Jan C. Devera

Master's Theses

The efficient delivery of potable water for a community through its distribution system has historically been the backbone of nearly all metropolitan developments. Much of these systems are comprised of pipe networks made of various materials including concrete, iron, PVC, and even steel. As these communities expand and urbanize, water demand and population density simultaneously increase. This develops higher strains and stresses in the community‟s water distribution network causing pipes to corrode, crack, or rupture prematurely while in service. As a result, the deterioration of water distribution systems in growing cities is increasingly becoming a major concern for our nation. …


Studying The Relationship Between Mud/Salt Flat Habitat And Shorebird Abundance At Two Wetland Areas Using Landsat, Dustin Reagan Jul 2013

Studying The Relationship Between Mud/Salt Flat Habitat And Shorebird Abundance At Two Wetland Areas Using Landsat, Dustin Reagan

Master's Theses

The objective of this project was to determine the degree and direction of association between the amount of mud/salt flat area and shorebird abundance during spring and early summer. This study used Landsat 5 to indirectly measure mudflat and salt flat areas at two wetland complexes within Kansas over a period of several years (1991-2008). These measurements were compared to shorebird surveys conducted by several individuals at both Quivira National Wildlife Refuge and Cheyenne Bottoms Wildlife Area. A correlation analysis showed that significant relationships exist between mud/salt flat area and the abundance of certain shorebird species. Correlation coefficients for individual …

Transient Hillslope Response To An Incision Wave Sweeping Up A Watershed: A Case Study From The Salmon River, Ryan Wood Jan 2013

Transient Hillslope Response To An Incision Wave Sweeping Up A Watershed: A Case Study From The Salmon River, Ryan Wood

Master's Theses

Base level lowering often leads to the migration of knickpoints up the fluvial network as the channel profile adjusts to the new lower boundary condition. In steep terrain, the passage of a knickpoint can oversteepen valley walls and trigger a wave of erosion up the hillslopes. As soil is stripped from hillslopes, the previously diffusive hillslopes are transformed to landslide-dominated. Soils in diffusive landscapes are well developed until erosion exposes the underlying saprolite by shortening the soil residence times. During base level adjustments, the erosion of hillslopes can leave relict patches of the original landscape juxtaposed with the newly evolving …
