Surface Water Evaluation, Modeling and Monitoring

R W Harden & Associates provides surface water-related services for a variety of client needs. Past efforts have focused on watershed characterization, calculation of runoff rates and directions, estimation of vadose zone infiltration, and prediction of the extents and magnitude of flooding. We routinely analyze both surface water quantity and quality for discharge permitting and conjunctive use applications where surface water is supplemented with groundwater supplies. Our experienced staff also conduct monitoring of surface water quality and quantity for baseline investigations, regulatory compliance, and impact mitigation for a variety of clients.

Ongoing urban development and associated changes in runoff patterns frequently result in unexpected flooding and erosion, which can lead to disputes between adjoining landowners. R W Harden & Associates regularly performs evaluations of the root causes of urban flooding and assists clients with the design and implementation of effective surface water control systems.
