Simulation Of Flow And Water Quality From Tile Drains At The Watershed And Field Scale, Colleen Moloney
Simulation Of Flow And Water Quality From Tile Drains At The Watershed And Field Scale, Colleen Moloney
Open Access Theses
Simulation models such as the Soil and Water Assessment Tool (SWAT) have become widely used in determining the water quality impacts of various management practices. Ensuring that the algorithms accurately represent the processes simulated has become an important goal. Tile drainage is a standard practice in the Midwest, US in order to reduce risk of yield loss due to excess water. Multiple tile drainage and water table algorithms have been available in the SWAT model between the initial SWAT release and revision 638 used in this study. Testing of those algorithms is often limited. Furthermore, algorithms in the current version …
Role Of River Bathymetry In Hydraulic Modeling Of River Channels, Sayan Dey
Role Of River Bathymetry In Hydraulic Modeling Of River Channels, Sayan Dey
Open Access Theses
Accurate geometric representation of the river channel is required for accurate hydraulic modeling of rivers. These are generally obtained through remote sensing techniques such as Light Detection and Ranging (LIDAR). However, these techniques lack the ability to model the submerged channel bed effectively and need to be complemented with surveyed bathymetric data for complete representation of the channel bathymetry, which can be time and cost prohibitive. An alternative to address this issue is to develop conceptual models that can estimate bathymetry.
This study aims to evaluate the potential of a conceptual model, the River Channel Morphology Model (RCMM) which estimates …
