Pyrohydraulic traits: the role of hydraulic segmentation as a hydraulic fuse in resisting fires
… remain unclear. The central claim of the hydraulic death hypothesis (HDH) is that xylem embolism may kill plants by preventing tissues that survive fires from remaining hydrated and has been suggested to explain rapid post-fire mortality. A corollary of the HDH is that it would be …

Hydraulic properties of asphalt concrete
… common to soil analysis, to characterize the hydraulic properties of asphalt concrete. Wetting and drying water characteristic curves were measured for six asphalt concrete cores. From the water characteristic curves, it is proposed that asphalt concrete may require bi-modal sigmoid curves to …

Hydraulic conveyance of solid capsules
The hydraulics of two phase flow of capsule - liquid mixtures is investigated experimentally and analytically. The technology of hydraulic transportation of solid capsules in pipes is advanced to the point of practical feasibility by the development and successful operation of experimental …

A comparison of electric and hydraulic approaches to fluid flow simulation and hydraulic parameters inversion
… aquifer drawdowns. By representing reservoir hydraulic conductivities as electric resistors and storativities as capacitors, simulating the potential response gives results similar to that of solving the hydraulic flow equations. Scaling the electrical parameters results in an equivalent …

Assessing safety margins and hydraulic strategies in Restionaceae: evaluating xylem hydraulic traits in two Elegia species
… in a landscape, which suggests that plant hydraulic strategies are an important ecological driver of responses to seasonality and intensity of drought events, especially in the face of climate and habitat change. Wide-spread mortality has been observed over recent decades as a result of …

Internal hydraulic jumps with upstream shear
Internal hydraulic jumps in flows with upstream shear are investigated numerically and theoretically. The role of upstream shear has not previously been thoroughly investigated, although it is important in many oceanographic flows such as exchange flows and stratified flow over topography. Several …

Hydraulic Fracturing in Earth Dams (Boreholes)
The proposed mechanisms of hydraulic fracturing in earth embankment dam cores and boreholes published by various authors have been outlined and compared in this investigation. An experimental study was conducted which reinforces the fact that hydraulic fracturing in boreholes is a tensile …

Geomechanical review of hydraulic fracturing technology
Hydraulic fracturing as a method for recovering unconventional shale gas has been around for several decades. Significant research and improvement in field methods have been documented in literature on the subject. The heterogeneous nature of shale has made hydraulic fracturing design to be unique …

The development of the hydraulic analogy
… accurate results can be obtained by using the hydraulic analogy. The analogy can be used in either the subsonic, transonic or supersonic range. The theory was intended to be general and showed that an exact analogy exists between free surface water flow and two dimensional gas flow. By …

Optimization of hydraulic networks using the box-complex optimization technique and the linear method of hydraulic analysis
… developed to be used in the optimal design of hydraulic networks. The computer program can be used to optimize three basic system variables; input hydraulic head, pump head, and discrete pipe diameter sizes. Since the basic network equations describing the system are nonlinear, the problem is …
