Dam operations can be examined through reservoir elevations, estimated or measured inflows and releases, gate and spillway records, operating procedures or water-control plans, design information, downstream constraints, and hydrologic data from the period surrounding the event. Those sources can help reconstruct available storage, release decisions, and the hydraulic conditions associated with the reservoir and downstream system. The analysis can then assess whether the observed upstream or downstream water levels are consistent with the documented operation and event conditions.
A hydraulic model can estimate water-surface elevations, flow depths, velocities, inundation, conveyance, and the effects of structures or restrictions under defined conditions. Model results depend on the geometry, flow and boundary data, roughness and loss parameters, and other assumptions used in the analysis. Comparing calculated results with surveys, observed high-water marks, photographs, measured water levels or flows, and other event evidence can help evaluate the model and test competing explanations for flooding, overtopping, backwater, or unexpected water levels.
Levees and dikes are barriers used to separate a water source from land or facilities intended to remain protected. Hydraulic evaluation may consider crest elevations, event water levels, overtopping, flow around termini or openings, interior drainage, and the capacity of pumps or outlets serving the protected area. Survey information, modeled and observed water levels, operating records, and event data can help assess whether those hydraulic conditions contributed to flooding. Questions involving seepage, internal erosion, settlement, or embankment and foundation stability may require geotechnical analysis.
Pumps influence the amount of water a system can move under particular head and operating conditions. Available flow may depend on pump characteristics, system head, suction and discharge conditions, controls, operating configuration, restrictions, and equipment condition. Pump curves, measured operating data, water levels, piping information, control records, and maintenance history can be compared to assess whether documented pump and system performance was consistent with the flow and head conditions required during the event.
