Short Summary

This dissertation comprises three studies: evaluating satellite precipitation products and hydrological models in Vietnamese river basins, projecting future hydroclimatic disaster risks in coastal Virginia using GCMs, and conducting a comprehensive global assessment of historical drought conditions and recovery using multiple soil moisture datasets.

Objective

• To investigate the performance of satellite-based precipitation products and the Soil and Water Assessment Tool (SWAT) hydrological model across diverse climate regions in Vietnam.
• To utilize General Circulation Models (GCMs) for mapping future hydroclimatic disaster risks in the Eastern Shore of Virginia by 2100.
• To provide an up-to-date, comprehensive assessment of global drought conditions and recovery using soil-moisture-based drought indices, examining historical development from 1950, particularly before and after 1982.

Study Configuration

• Spatial Scale: Eleven river basins in Vietnam (Study 1); Eastern Shore of Virginia, USA (Study 2); Global (Study 3).
• Temporal Scale: Implied recent period for product evaluation (Study 1); Projections by 2100 (Study 2); Historical 1950–2024, with focus on pre/post 1982 (Study 3).

Methodology and Data

• Models used:
  • Comprehensive Assessment Framework of Rainfall (CAFR)
  • Soil and Water Assessment Tool (SWAT)
  • General Circulation Models (GCMs) from NASA Earth Exchange Global Daily Downscaled Projections (NEX-GDDP-CMIP6)
  • Soil-moisture-based drought indices
• Data sources:
  • Six satellite-based precipitation products (SPPs), including NASA GPM IMERGF.
  • NASA Earth Exchange Global Daily Downscaled Projections (NEX-GDDP-CMIP6).
  • Five soil moisture datasets: NASA Soil Moisture Active and Passive (SMAP) (2015–2024), ECMWF Reanalysis v5 (ERA5)-Land (1950–2024), European Space Agency (ESA) Climate Change Initiative (CCI) Active and Combined (1978–2023), and Global Land Evaporation Amsterdam Model (GLEAM) (1980–2024).

Main Results

• The second study projected an increase in drought trends through 2044 for the Eastern Shore of Virginia.
• The dissertation provides comprehensive assessments of satellite-based precipitation product performance, future disaster risk mapping, and global historical drought conditions and recovery characteristics. (Specific quantitative results for Study 1 and 3 are not detailed in the abstract).

Contributions

• Development and application of the Comprehensive Assessment Framework of Rainfall (CAFR) for evaluating satellite precipitation products.
• Comprehensive assessment of global drought conditions and recovery, addressing an underexplored area, particularly on a global scale.
• Maximizing the use of diverse satellite remote-sensing and reanalysis datasets for hydroclimatic extreme analysis.
• Providing insights for disaster prevention, prediction, and water resources management for stakeholders and authorities.
