Environmental Research:

We are proposing to investigate the paleo-hydrologic setting of the previous wet climatic periods across the Empty Quarter. This will be enabled through the integration of observations collected in the field and others extracted from remotely acquired data including: (1) distribution of paleolakes from Landsat images, (2) distribution of paleo-stream networks from radar images, and […]

We are using temporal satellite radar data to measure the spatial and temporal variations in subsidence rates across the entire Delta, identify the nature of the factors controlling modern subsidence, and predict the Delta response to these forcing factors over the next century.  The interplay between natural and anthropogenic parameters controls subsidence rates and determines […]

We are developing and applying an interdisciplinary system approach involving analysis of GRACE, remote sensing, and relevant data sets (e.g., stream flow) along with hydrologic modeling to accomplish the following: (1) develop quantitative macro-scale hydrologic distributed grid models (grid size: 0.5° x 0.5°) for the African continent that can account for vertical and lateral mass […]

  New research on fault-groundwater interaction in arid regions of the Middle-East has revealed the potential that fault structures can be potential groundwater conduits. Faults are normally viewed as groundwater barriers especially in alluvial systems. The Helendale fault which crosses through the Este Groundwater Basin has always been seen as a barrier to groundwater movement […]

  We are developing and applying an interdisciplinary system approach (involving analyses of GRACE gravity, remote sensing, and geochemical data, along with hydrologic modeling) to assess and calibrate GRACE data for monitoring groundwater recharge, discharge, and flow in large-scale aquifers. The Nubian Aquifer of North Africa was chosen as a test site, because its extensive […]

This is a collaborative project to develop a web-based GIS relational database for geological data sets for Saudi Arabia. It will comprise digital topographic, geologic maps, and remote sensing, seismic, geochronologic, geochemical, and isotopic data. We will compile and organize datasets, develop metadata files, and assemble online tools for visualization. The tasks will be conducted […]

GeoInformatics:

This is a collaborative project to develop a web-based GIS relational database for geological data sets for Egypt. It will be comprised of digital terrain elevation data, digitized geologic maps, remote sensing, seismic, geochronologic, geochemical, and isotopic data. We will organize datasets, develop metadata files, and assemble online tools for visualization. The GIS and web-based […]
