The physics of tree hydraulics can be conveyed with simple fluid dynamics based upon the Hagen-Poiseuille equation and Murray's law. WebHydraulic structures. When water must be managed, moved or used, some form of hydraulic structure is needed. This simple fact requires that engineers develop efficient hydraulic structures; e.g., for – reservoirs; water, waste-water or storm-water conveyance; control of sediment, air, chemical, and woody debris transport; and, the well-being ...
