Capítulo 7: Diseño de canaleta Parshall

I. INTRODUCTIONThe Parshall Flume, which was invented in 1920 by R. Parshall, is mostly used wastewater and crop supply. Utilizing equations, established dimensions that fit the design, one of advantages conversion position energy to velocity since other measurement structures there are minimum losses this it does not allow sedimentation.
 The structuring project adhered different models define its behavior limit use. This case an approach length channel entrance, nothing more than a primary distance for action flow within channel. Throughout history, some studies were conducted attempt establish approximate realistic value at time measurements, but theories put forward lost. Some people link with narrowing gorge, others suggest conditions before entering flume.
 For development respective objectives, carried out: measurement, points already field will be taken help total station, GPS, verify measurements flume. calculations introduced civil 3D able if correct ones what distances they have between them, through this, we can apply methods design has evaluation layout gutter, case, carry out plan data calculated office evaluate situation so possible solution defect occur.
 In report, focus on redesign hydraulic irrigation where find section, function measuring found section. verified using formulas software correct, say well designed, otherwise look doing study.
