The Peligre Hydroelectric Reservoir is one of the principal energy sources of Port-au Prince.

The firm is performing the permitting, civil design and project management activities for the Playa Hermosa project in Vega Baja, Puerto Rico.

The Loiza Reservoir is the principal source of water supply to Puerto Rico’s metropolitan area. The reservoir was dredged in the late 1990s and is expected that dredging will be required every 20 years.

The firm directed a joint-venture baseline (post-construction) sedimentation study at the Yacyretá reservoir on the Río Paraná between Argentina and Paraguay.

Full accountability water audit involving approximately 25,000 water customers in 3 pilot areas, plus approximately 2000 large-meter customers island-wide.

It was necessary to provide 80,000 gpd of wastewater treatment for a new commercial development and cricket stands associated with the International Airport at Antigua, West Indies.

A numerical groundwater model was constructed to simulate groundwater flow in the Yauco Alluvial Valley aquifer.

Río Huanuni is dominated by alternating mud flows and scour events, resulting in vertical variations in the riverbed elevation of approximately 5 to 8 meters.

The City of La Paz is constructed on extreme slopes and has an undersized drainage system.

The firm conducted a bathymetric survey of El Cajón hydroelectric reservoir in Honduras.

The firm undertake a firm yield analysis of all raw water intakes and reservoirs operated by the Puerto Rico Aqueduct and Sewer Authority.

The firm performed a FEMA flood map amendment for a proposed residential project located within the Río Coamo floodplain area.

The firm undertook feasibility level design and prepared an Environmental Impact Statement document (EIS) for Beatriz Offstream Reservoir

Challenge The City of Cagua has experienced chronic water shortages for many years.

Río Huanuni is dominated by alternating mud flows and scour events, resulting in vertical variations in the riverbed elevation of approximately 5 to 8 meters

Río Maniqui in the Beni area of Bolivia is a meandering alluvial sand-bed river which began moving laterally at the rate of about 20 m per year at the point of bridge construction.

The firm designed low-impact stormwater management features for a proposed residential project with the aim of providing some level of water treatment through filtration as well as minimizing peak flow discharges by the application of infiltration.

The project consists of the design, permitting and construction supervision for streambank erosion control for Gurabo River.

A hydrologic-hydraulic model was undertaken to analyze de effect of the proposed 4 km bridge over the floodplain of Río Guayanés in Yabucoa.

A total of 45 damsites were analyzed and ranked. Feasibility-level design studies which included preliminary geotechnical explorations were conducted at the five most promising sites.

An accelerated rate of sediment accumulation was projected at the proposed Changma reservoir, Shule River, Ganzú, China.

The firm performed hydrologic and hydraulic engineering studies, spillway sizing and design parameter, intake hydraulic design, and impact on environmental instream flows.

The firm performed hydraulic analysis and civil design
