On February 17, 2006, a massive rock slide-debris avalanche occurred in the Philippine province of Southern Leyte, causing widespread damage and loss of life. The deadly landslide (or debris flow) followed a 10-day period of heavy rain and a minor earthquake (magnitude 2.6 on the moment magnitude scale). The official death toll was 1,126. [1]
Most debris consists of small plastic particles suspended at or just below the surface, evading detection by aircraft or satellite. Instead, the size of the patch is determined by sampling. The estimated size of the garbage patch is 1,600,000 square kilometres (620,000 sq mi) (about twice the size of Texas or three times the size of France). [52]
So a net 1.5 in height will provide a trellis or espalier between 1.80 and 1.90 m (so the post sizes should be around 2.2 and 2.5 m), and this would be the ideal support system measurement for most cucumber open field varieties. The ideal size for square mesh is approx. 25x25 cm.
Before a storm that can potentially nucleate debris flows, forecasting frameworks can often quantify the likelihood that a debris flow might occur in a watershed; [18] however, it remains challenging to predict the amount of sediment mobilized and therefore, the total size of debris flows that may nucleate for a given storm, and whether or not ...
They use bamboo rods called sungay ("horn"), each of which has a pulley at the end of the bamboo and cable attached to a net with a weight (pabigat)made of molded lead, installed at the bow and stern of the boat, two on both sides on the first section of the boat, two on both sides on the midsection of the boat and two again on the last part of the boat each of the bamboos has a pulley and ...
For example, in order to obtain small invertebrates measuring 50 to 1500 μm, a net mesh size between 25 and 50 μm diameter should be selected, which is sufficient to effectively filter only the target organism. [3] However, in a eutrophic water condition, a plankton net with a mesh larger than 100 μm should be chosen to avoid clogging the ...
Small passerines are typically captured with 16-30 mm mesh, while larger birds, like hawks and ducks, are captured using mesh sizes of ~127 mm. Net dimensions can vary widely depending on the proposed use. Net height for avian mist netting is typically 1.2 - 2.6 m. Net width may vary from 3 to 18 m, although longer nets may also be used.
Salambáw (Spanish: salambáo or sarambáo), is a type of lift net used by indigenous fishermen in the Philippines. They are found throughout the Philippine islands but are most prevalent in large lakes like Laguna de Bay , and sheltered coastal areas like Manila Bay , Ragay Gulf , and Batan Bay .
