A Numerical Investigation Of The Implications Of Altered Channel-Floodplain Connectivity On Hydrodynamic Flood Wave Processes, Colin F. Byrne
A Numerical Investigation Of The Implications Of Altered Channel-Floodplain Connectivity On Hydrodynamic Flood Wave Processes, Colin F. Byrne
Civil Engineering ETDs
With severely altered rivers throughout the developed world, hydrodynamic processes and floodplain connectivity have changed drastically. The research presented here focuses on quantification of two hydrodynamic processes: flood wave attenuation and channel-floodplain fluxes. Objectives of the three research chapters were to (1) evaluate how the ecosystem service of flood wave attenuation has changed with the implementation of river engineering practices as well as contemporary river restoration efforts, (2) describe the sensitivities of flood wave attenuation to contemporary and altered conditions, and (3) characterize channel-floodplain connectivity through lateral flux metrics. All chapter objectives were met using high-resolution, two-dimensional hydrodynamic modeling techniques …
Ground Water-Surface Water Interaction Of Rio Grande Biopark Area, Albuquerque, New Mexico, Sadia Faiza
Ground Water-Surface Water Interaction Of Rio Grande Biopark Area, Albuquerque, New Mexico, Sadia Faiza
Civil Engineering ETDs
Ground water and surface water are typically considered as separate entities, but all surface water features interact with ground water in different ways. Better understanding of ground water-surface water interaction is important for effective land and water management. This study investigated the impact of surface water on ground water levels as well as soil moisture content in a small region of Albuquerque Biopark near the Rio Grande. This study involved collection of field data on soil moisture, ground water levels and observations of vegetation densities adjacent to the Biopark wetlands. Numerical models were developed of the influence of the river …
