Water Losses Management In Mitrovica Region, Faruk Hajrizi, Izet Ibrahimi

UBT International Conference

The purpose of this paper is to reduce water losses by presenting the unregistered customer situation, the number and where they are mainly distributed. In the context of analyzing the commercial and technical losses of the water in the Mitrovica region, a project for the reduction of water losses was devised. Financial support for project realization is ensured by the project funded by the Luxembourg Government for the Regional and Water Company Mitrovica, which has enabled to implement a project with significant activities to reduce water losses. During the project development we undertook site visits, field work evaluations were conducted …

Identification Of Transportation Infrastructure At Risk Due To Sea Level Rise And Subsidence Of Land In Coastal Louisiana, Sanjay Tewari, Wesley Palmer

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The coast of Louisiana is under threat because of sea level rise and land subsidence. Sea water is encroaching deeper inland and as a result Louisiana is losing at an alarming rate. The combined effect of sea level rise and land subsidence is variable spatially. This paper focuses on this combined effect in identifying the transportation infrastructure that is at risk of getting affected by the sea-water inundation of the land.

This paper is an attempt of taking account of land elevation data monitored continuously at various locations along the coast of Louisiana and combining it with local sea level …

1-Dimensional Hydraulic And Sediment Transport Modelling Of An Emergency Spillway, Ryan Weise

Electronic Thesis and Dissertation Repository

Hydropower dams are complex structures that require a high level of safety. Systems approach and system simulation have provided new insights into evaluating dam safety. System simulation of hydropower dams requires that the physical state of the critical infrastructure be represented. A 1-dimensional hydraulic and sediment transport model was developed within HEC-RAS to address erosion in an emergency spillway for an existing system simulation model. Various inflow events were simulated, and the ensuing erosion was evaluated. A range of Manning’s roughness coefficients were tested and the sensitivity was minimal. Erosion and deposition values were not accurate but offer an understanding …

Bathymetry Data For Lakes Azuei And Enriquillo, Michael Piasecki, Mahrokh Moknatian

Publications and Research

This data set supports and forms the basis for the development of Digital Bathymetry Models (DBM) for Lakes Azuei (Haiti) and Enriquillo (Dominican Republic). Bathymetric Data is typically acquired using Sonar devices that measure the depth at specific points along a boat track and for which the longitude and latitude is recorded. From the resulting point cloud one develop a seamless representation of the floor of the lake on either a raster set (which is what we have done) or try to use a contour (vector representation) model in which the depth contours appear as polygons or -lines. The raw …

Systematic Approach To Identifying Deeply Buried Archeological Deposits, Anthony L. Layzell, Rolfe D. Mandel, Courtney L. Ziska, John R. Bozell

Nebraska Department of Transportation: Research Reports

This project is designed to assist cultural resource specialists involved in Nebraska Department of Transportation (NDOT) and the Federal Highway Administration (FHWA) project planning and development. The goal was to develop Geographic Information System (GIS) data layers that spatially delineate different landform-sediment assemblages (LSAs) and depict the associated geologic potential for buried cultural deposits in select watersheds in Nebraska. The Nebraska Buried Sites GIS resource will allow planners and cultural resource specialists to determine whether future project areas are likely to be free of deeply buried sites or whether subsurface exploration is necessary.

Land Suitability Analysis For Emergency Medical Services Posts Along State Highways: A Case Study Of California, Ernest Tufuor, Laurence Rilett, Yunwoo Nam, Antonio Hurtado Beltran

Department of Civil and Environmental Engineering: Faculty Publications

The response time of Emergency Medical Services (EMS) to road accidents can be the difference between life and death. The California strategic highway safety plan highlight the need to improve the response time and recognizes that: 37% and 8% of the fatal crashes are 30 or more miles away from a trauma center in rural and urban areas respectively.

The paper seeks to: (1) demonstrate the viability of using spatial multi-criteria analysis in road safety management, and (2) provide a good scientific justification in selecting optimal counties for EMS posts. The goal is to propose areas that are close to …
