Catchment hydrology
Catchment hydrology is the study of how water is collected, stored, and flows within a drainage basin (catchment). Water comes from rainfall, runoff, groundwater, snowmelt, and other sources, and moves downhill under the influence of gravity. Hydrologists measure rainfall and snowfall to estimate water availability, while the shape and slope of the land determine how […]
Centrifugal Pump
A centrifugal pump is a dynamic pump that moves liquids by converting the rotational energy of a motor-driven impeller into pressure and flow. As the impeller spins, liquid enters through the center of the pump, is accelerated outward by centrifugal force, and is discharged through the pump casing at a higher pressure. Centrifugal pumps are […]
Detention, Conveyance & Freeboard Requirements in Plano
According to the City of Plano Drainage Design Manual, stormwater management is built on three key standards: detention, which temporarily stores runoff and releases it at controlled rates; conveyance, which safely carries stormwater through pipes and channels; and freeboard, an added vertical safety margin above calculated flood elevations to address uncertainties and extreme rainfall.
