Although this method has been renewed a few times, there is a need to update this method involving more thorough statistical methods.
This method involved more liberal inclusion of specimens for molecular processing and deliberately excluded one large-bodied, conspicuous (blue-coloured), and common morphospecies.
Other disposal methods involve more tunneling, such as within salt, which has particularly good ability for shielding against radiation.
The unprecedented survey, carried out by Allen's company Vulcan with £7m of funding, is the first continent-wide aerial survey of African elephants using standardised data collection and technical validation methods, involved more than 90 scientists, six NGOs and many volunteers and conservationists on the ground.
Most of the above-mentioned methods involved more than one measurement and were too cumbersome.
However, most of these methods involve more than one step, high energy requirement, low material conversions, difficulty in purification, and hazardous chemicals [13].
On the other hand, Free-Report Protocols and Think- Aloud Protocols have the advantage as compared to other information acquisition methods, involving more asking specific questions to the doctors, that they are minimally affected by the investigator's expectations.
The method also involves more insidious traps.
Hence, the simplified method with easier calculation but poorer accuracy may be employed to estimate the maximum storage volume in the preliminary design stage, while the hydrological routing method, which involves more complicated calculation but gives more precise estimation, is better suited for application in the detailed design stage.
