Hydraulic and Hydrologic Analyses

Using a variety of methods, the Engineering Division at LandStudies prepares hydraulic and hydrologic analyses to fit each site and project’s regulatory requirements. These methods include TR-20, Rational, and Regional Regression Equations, HEC-RAS-enabled flood studies and bridge modeling, and HY-8 culvert modeling. We offer complete stormwater management design services, featuring site characterization, assessment and survey, runoff calculations, innovative best management practice (BMP) design, and Erosion and Sediment (E&S) Control Plans. Our Engineering Division is experienced at developing and submitting documentation related to General and Joint Permits, E&S, the National Pollutant Discharge Elimination System (NPDES), and municipality specific permits required for a project. LandStudies also prepares stormwater retrofit designs to remediate existing problems and meet water quality and recharge goals. To this end, we are capable of modeling water quality BMPs using WINSLAMM and other tools to quantify nutrient and volume reductions.

Engineering and Science Team

The Engineering and Science team at LandStudies features Engineers and Geomorphologists with extensive experience in fluvial geomorphic assessment and stream restoration design. Our approach includes a comprehensive understanding of the landscape as well as the geology, hydrology, sediment transport characteristics, and historical and anthropogenic influences of a given system. Moreover, LandStudies staff understands the importance of implementing a detailed Level I, II, III, and IV (Rosgen, 1994) geomorphic investigation and design approach to stream and floodplain restoration. This approach dictates that our staff has considerable knowledge of the reach or system in question, which requires study of its base level control, existing geomorphic conditions, and sediment regime and transport characteristics.

Evaluation and Analysis

Our Engineers and Geomorphologists are trained to understand the origin and severity of stability problems, and are experienced in making subtle and critical field observations, collecting and analyzing the necessary data, providing appropriate recommendations and solutions, and reporting in a manner that well-informs the design process.
