Our personnel have the training and hands-on experience with field data gathering and computer simulations required for surface water analyses and design of hydraulic structures, ranging from small stormwater drainage systems to dam spillway and release chambers. These include rainfall/runoff evaluation of specific flooding events, as well as continuous (time series) hydrograph simulations. Our hydraulic engineers are well versed in evaluating steady as well as unsteady flow applications for both open channel and pressure (i.e. pipe-flow) conditions.

In addition, GZA hydrologists and water resources scientists have the practical experience and academic training to apply statistical methods to characterize stream flow in a watershed. Our abilities include:

• Water budget and inflow/outflow
• Analysis of stream gage data
• Confirmatory field measurement of stream flows and stream geometry transects
• Application of regional regression equations and synthetic flow duration methodologies
