The 335 MW expansion adds a second powerhouse, immediately downstream of the Waneta Dam on the Pend-d'Oreille River, that shares the existing hydraulic head
and generates clean, renewable, cost effective power from water that would otherwise be spilled.
The maximum possible hydraulic head
-35 cm, the sample height -4 cm, the cross-section area -40 [cm.
It was assumed here that the lowest rate of fall in hydraulic head
that could be reliably measured in the field (taking into account measurement error, small changes in surface water level over time, change in water temperature, etc.
The hydraulic head
of the aquifer varies between the altitudes of 150 and 155 m a.
When a well is pump in a confined aquifer, the declining hydraulic head
in the vicinity of the well enables the pressurized water to expand slightly, adding a small volume of additional water.
The dewatering process, by pumping water from the surrounding groundwater body, imposes stresses on the system, which change the distribution of hydraulic head
These data along with ground elevation were used in the computation of the hydraulic head
These valves are also used in controlling the required hydraulic head
Therefore, the aquifer permeability and transmissivity was enhanced in the hydraulic head
The official said a boost reservoir would also be built in sector D-11 against pumped supplies from Shah Allah Ditta that would cater for supplies to the topographically elevated sectors of F-10 and 11 and G-10 and 11 with sufficient leftover hydraulic head
to allow for activation of overhead reservoirs in sectors G-10/2.
The basic scheme of this structure is depicted in figure 1a where: z--is the drainage norm, h--is the hydraulic head
Medium to large scale bakers and confectioners will appreciate the new hydraulic head
raising and lowering mechanism and bowl locking system, which secures the bowl tightly in position for increased stability and safety when in operation.
