5. A DFB-SOA Based Optical Vector Network Analyzer for Characterization of Bandpass Optical Devices.

Abstract

In this paper a novel optical vector network analyzer (OVNA) utilizing a distributed feedback semiconductor optical amplifier (DFB-SOA) is introduced. The proposed OVNA is implemented by converting the transmission response of the optical device under test (ODUT) into the electrical domain. The main principle of the OVNA is predicated on the optical carrier restoration facilitated by the wavelength-selective amplification attribute of the DFB-SOA. The implemented OVNA effectively determined the transmission spectrum of an optical filter possessing a passband of 9-GHz bandwidth, achieving a commendable resolution of 25 MHz in the measurement process. The dynamic range of the OVNA can be broadened by adjust the driven current under the DFB-SOA. Additionally, the detection range of our system can be expanded through the utilization of broadband optoelectronic devices. Furthermore, the OVNA possesses considerable potential for integration onto a single chip. [ABSTRACT FROM AUTHOR]

Abstract

Slackwater deposits representing past flood events provide a robust means to extend systematic gage records further back in time, place historic floods in a longer-term context, and reduce uncertainties in flood hazard analysis. The identification and application of slackwater deposits in riverine paleoflood hydrology has traditionally been limited to arid bedrock-controlled environments and periglacial environments. In this study, we utilize methods developed in humid alluvial settings and apply them to slackwater deposits, one of the first studies to do so. This novel approach uses sediment texture and geochemistry to distinguish slackwater deposits from in situ material in a temperate alluvial setting. We identify multiple slackwater deposits in two rock shelters situated on bluffs adjacent to the lower Ohio River. Flood age estimates are based on optically stimulated luminescence (OSL) dating, and discharge estimates are based on a 1D HEC-RAS model. The uppermost slackwater deposit at both sites corresponds to the AD 1937 historic flood of record (∼31,400 m3/s), while another slackwater deposit identified only at the lower elevation site corresponds to a paleoflood that occurred around AD 1650 with a discharge of ∼23,900 m3/s. Our findings imply that the AD 1937 flood represents the largest magnitude flood on the lower Ohio River in at least the last 400 years. Inclusion of the paleoflood into a flood frequency analysis for the Ohio River at Louisville reduces uncertainties in large flood quantiles by ∼50%. [ABSTRACT FROM AUTHOR]

14. Constraining lithosphere viscosity structure using Lower Mississippi River long profile deformation

Author

Hill, Alexander, Kuchar, Joseph, Shen, Zhixiong, Milne, Glenn A, and Tornqvist, Torbjorn

Abstract

In this investigation we model solid Earth deformation as constrained by vertical displacement of the Lower Mississippi River long profile over the past ~80 kyr. These observations are compared to output from a model that simulates glacial isostatic adjustment and sedimentary isostatic adjustment using a spherically-symmetric, viscoelastic Earth model. Observations of long-profile displacement based on optically-dated sediment cores, were revised to account for the effect of fault displacement in the southern end of the long profile inferred in some recent studies. Due to the relatively localized sediment loading associated with the Mississippi Delta System, the vertical displacement of the long profile over the past ~80 kyr is highly sensitive to lithospheric structure. For this reason, these observations offer a valuable opportunity to constrain mechanical properties of the lithosphere beneath the south-central United States. To pursue this opportunity, we consider multiple model scenarios in which the lithosphere is either entirely elastic (a common assumption in surface loading studies) or has internal viscosity structure. In the latter case, viscosity structures are determined using a range of plausible geothermal gradients and seismic constraints on Moho depth. In the elastic case, model lithosphere thicknesses are fixed at 46 km, 71 km, 96 km, or 120 km. For each modelling scenario (elastic vs viscous), constraints on lithosphere thickness and structure, and the ability of the model to match the observations will be presented., The 28th IUGG General Assembly (IUGG2023) (Berlin 2023)
