Detailed Water Resources Studies in All Al-Harrat & Main Valleys
Hydrology & Hydrogeology
Overview
Commissioned by the Ministry of Environment, Water & Agriculture, this was one of ERCAN's largest and longest-running engagements — a comprehensive characterisation of the water resources held within the Kingdom's Harrat lava fields and its principal valley systems.
Scope
- Data acquisition, management & analysis
- Water resources monitoring network & climatic environmental evaluations
- Hydrology, water-demand & resources management plan
- Mathematical groundwater-flow model & well inventory (20,000 existing wells)
- Geophysical field survey, logging & pumping tests; drilling 23,000 m
- Chemical & isotopic investigation
Engineering Challenge
Quantifying the renewable and non-renewable water stored across vast, geologically complex volcanic terrain — and building a defensible model that planners could trust for decades of national water policy.
Delivery & Outcome
ERCAN deployed an integrated programme: a kingdom-wide monitoring network, an inventory of 20,000 existing wells, 23,000 metres of drilling, geophysical logging, pumping tests and isotopic chemistry, all fused into a single mathematical groundwater-flow model.
A unified water-demand and resources-management plan that informs long-term planning across the Harrat and main valleys — delivered over nearly eight years of continuous fieldwork.
