Irrigation schedules were based on outdated data.

Solution

Introduced real‑time soil moisture monitoring, increasing crop yield by 12%.

Problem

Municipal water demand forecasts were inaccurate.

Solution

Developed a predictive model that improved forecast accuracy by 18%.

Problem

Groundwater contamination was spreading unchecked.

Solution

Designed a remediation strategy that reduced contaminant plume size by 45%.

Problem

Water allocation conflicts among users were frequent.

Solution

Created a transparent allocation framework, decreasing disputes by 70%.

Project Examples

Real‑world initiatives that demonstrate impact

Groundwater Recharge Modeling
9 mo
Situation
A regional water authority needed to increase sustainable yields in a semi‑arid basin experiencing declining water tables.
Action
Developed a MODFLOW model calibrated with 10 years of well data, simulated recharge scenarios, and identified optimal artificial recharge locations.
Result
Projected a 15% increase in sustainable yield over 20 years while maintaining ecological flow requirements.
+15% sustainable yieldModel calibration R² = 0.92Reduced water‑table decline from 2 ft/yr to 0.4 ft/yr
Urban Flood Forecasting System
6 mo
Situation
A mid‑size city faced frequent flash floods after intense storms, lacking timely warnings.
Action
Integrated HEC‑RAS with IoT rain gauges and a cloud‑based dashboard; automated alerts to emergency services.
Result
Reduced flood response time by 35% and lowered property damage by an estimated $2.3 M annually.
