RIZZO’s hydrologic and hydraulic engineering services include conventional and probabilistic analyses of local intense precipitation and probable maximum precipitation events; estimations of probable maximum floods on streams and rivers; and evaluation of storm, seiche, and tsunami waves and subsequent flooding.

RIZZO’s hydrologic and hydraulic engineering services also include 3-D, 2-D, and 1-D modeling of inflow design floods and design modifications for dams and other hydraulic structures, dam breach analyses, and shoreline and streambank erosion hazard evaluations and scour analyses.
