News and Events

Lanka Hydraulic Institute Ltd. (LHI) is undertaking the Initial Environmental Examination (IEE) for the 24 Nos. Tanks Development Project in Sri Lanka for the Ceylon Petroleum Corporation (CPC). LHI is assessing the environmental and social impacts of rehabilitating and operationalizing 24 petroleum storage tanks at the Trincomalee Oil Tank Farm Complex. The IEE covers construction and operational impacts, petroleum-spill and fire risks, hazardous-material handling, infrastructure, and marine interfaces, while developing an Environmental Management Plan, monitoring programme, and quantitative risk analysis.

Lanka Hydraulic Institute Ltd. (LHI) is undertaking the Consultancy Services to Design a Digital Platform for Automated Data Ingestion, Modelling, and Simulation in Sri Lanka for the Food and Agriculture Organization (FAO). LHI is developing an automated flood monitoring and forecasting platform for Batticaloa, integrating real-time rainfall and water-level data from 20 stations with nine-day ECMWF forecasts. The platform includes data quality control, hydrological modelling support, web-based visualization, and multi-format data export to strengthen flood early warning, reservoir operations, and emergency decision-making.

Lanka Hydraulic Institute Ltd. (LHI) undertook the Hydrological and Hydraulic Assessment for the Proposed Recreational Development at Kor Al Hifri, Barka, Oman, for Meridian Engineering Consultancy, Oman. LHI conducted catchment hydrology, design-flood estimation, 2D hydrodynamic modelling, flushing and water-quality assessments, canal-dimension verification, and stormwater-management recommendations. The studies supported the Concept Masterplan and structural design of an approximately 80 m wide, 4.5 m deep waterbody with parallel breakwaters, ensuring safe berthing, effective circulation, reduced sedimentation, and resilience under extreme flood conditions.

Dutch Bay Onshore Wind Farm Project, Sri Lanka, is a proposed 150 MW renewable energy development for HVEN Renewable Energy Ltd. Lanka Hydraulic Institute Ltd. (LHI) conducted the Environmental Impact Assessment between February and November 2025, evaluating environmental and social impacts across design, construction, and operation. The EIA included regulatory review, baseline studies, stakeholder consultations, impact assessment, mitigation measures, cost–benefit analysis, a Grievance Redress Mechanism, and an integrated monitoring framework to support sustainable implementation.

Reassessment and Validation of the Hydraulic Design of the Salinity Barrier across the Nilwala River, Sri Lanka, was undertaken for the National Water Supply and Drainage Board (NWSDB). Lanka Hydraulic Institute Ltd. (LHI) conducted desk studies, field investigations, hydrological assessments, and 1D and 2D hydraulic modelling to reassess the barrier’s hydraulic performance. The study evaluated flood flows, upstream inundation, and temporary cofferdam impacts, producing flood inundation maps and a technically justified assessment to validate the original design and address stakeholder concerns.
