Evaluation Of Two-Dimensional Hydraulic Modeling In A Natural River And Implications In Instream Flow Assessment Methods, Karl L. Tarbet
Evaluation Of Two-Dimensional Hydraulic Modeling In A Natural River And Implications In Instream Flow Assessment Methods, Karl L. Tarbet
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The Logan River was used as a study site to assess the capabilities of two-dimensional depth-averaged hydraulic modeling in the x-y plane of a natural river for use with instream flow studies. Data were collected to spatially represent the study reach with depth, velocity, northing, easting, elevation, and substrate values using a total station and electronic velocity meter. Computational finite element meshes were generated using four different density levels of geometry data to examine the relationship between field data density and computational mesh on geometry errors. Geometry errors were found to be related to smoothing effects, which removed complex channel …
Risk Assessment Of Sloping Land Using Gis-Based Mapping, Phil N. Flentje, Robin N. Chowdhury
Risk Assessment Of Sloping Land Using Gis-Based Mapping, Phil N. Flentje, Robin N. Chowdhury
Faculty of Engineering and Information Sciences - Papers: Part A
In this paper, attention is drawn to GIS-based techniques for mapping and risk assessment for slopes and landslides. The authors focus on an approach developed recently for mapping of geology and slope stability in the Northern Illawarra (or the Northern Suburbs of Greater Wollongong Area) in New South Wales, Australia. The use of databases of geology and land instability and use of other GIS-based information relevant to sloping land for the development of a valid hazard and risk assessment procedure is explored. The developed approach will be applicable to other sloping areas and, in particular, urban areas both nationally and …
