Methodology
- GIN-method curtain grouting parameter envelopes (Khatib, Water Practice & Technology, 2022)
- Thermo-mechanical analysis of insulated diaphragm walls in PLAXIS 2D (2025)
- Gravity-vs-arch dam comparative load and seepage modelling
- Site-specific characterisation of Lebanese clay and limestone substrates
Representative work
- Curtain grouting recommendation envelope, Lebanese gravity dam (2022)
- Insulated diaphragm-wall PLAXIS case study, urban excavation (2025)
- Groundwater dam — comparative analysis between gravity and arch (2025)
- Slope stability and water-quality risk assessment, Alkalaa, South Lebanon (2024)
When this engagement makes sense
- A dam or curtain-grouting envelope needs defensible re-validation.
- An urban excavation requires a thermo-mechanical PLAXIS case-study before signoff.
- A water-resource project needs published methodology behind the recommendation.
A 42% reduction in seepage flow under a Lebanese gravity-dam foundation, after two staged GIN-method injection passes with continuous back-pressure monitoring.
Methodology validated against research published in Water Practice & Technology (DOI 10.2166/wpt.2022.083). Calibrated to local geology. Documented in a report that holds up to ministry review.
The dam was leaking. The math was not.
