The western boundary is not fixed as there is a large pond just outside the boundary and while the main flow path is south, at high water levels, this pond can also spill into the study catchment. The study site is bounded in the east by a railway embankment with two culverts. Each ...
Risk analysis tools within the risk assessment flow chart Full size image Table 1 Overview of risk analysis tools and examples of application Full size table A detailed analysis of each of the tools, including case studies, is now presented sequentially: Hazard and operability study (HAZOP) It ...
In addition, proper sampling techniques must be used to ensure that a sample is representative of the flow in the sampled cross-section. The number of verticals to be sampled in a cross-section should relate primarily to the collection of a representative sample and secondarily to the volume ...
4.1. Result Analysis and Summary of Initial Scenario before Water Dump The influence of the height of the helicopter tank bottom above the ground and of wind speed on the distribution scope of wake flow was analyzed and is summarized as follows. Figure 21 shows the distribution of wake flow ...
Concerning the installation of water-saving devices and the retrofitting of old fixtures, residents sometimes exhibit habits in addressing water leaks in faucets and toilets. Nevertheless, installing water saving equipment with flow controls and sensors is still never for families (Table5). ...
The spray collector unit serves to obtain the flow distribution and temperature variations across the spray. For each test, water was dispensed for 60 sec. During this time, the collected water did not overflow in any of the cups. This made it possible to calculate the relative volume of ...
During the stability test, two peristaltic pumps mixed 20 ppm SMX and 0.4 g L−1 PMS at a flow rate of 0.5 mL min−1, respectively, and the liquid did not flow back to the original beaker after the reaction. The collected post-reaction liquid (1 mL) was added to ...
While the two control dams, many channels and canals, and the drainage basin reservoirs may be controlled by humans, the rates of rain, evaporation, erosion, ice jams, and other water-flow phenomena are beyond human manipulation. The policies of local jurisdictions may have different effects than...
Added advantages include controlling groundwater flow direction and velocity within the treatment zone, and the potential to reduce potential flow into existing preferential pathways. To determine the feasibility of adding such a pumping component, a pumping test was performed using the wells...
Towards the southeast part of the study area, the N–S oriented, elongated sheet-like mud prone debris-flow deposits were observed (Figs. 6 and 10). The significant presence of erosional grooves indicates the presence of large cohesive sediment blocks were within the base of the flow for a ...
