A flow-measuring system has a weir wall bounded on a front face by a body of water and having a rear face and a top edge over which water from the body flows. A structure generally formed as an airfoil is mounted on the top edge such that water flowing over the weir wall must flow...
A suitable hydraulic structure, even in inclined watersheds within almost any runoff basin, is the construction of a weir and the experimental measurement of the corresponding water flow characteristics. Until now, the geometrical characteristics of such flows were limited in horizontal watersheds or ...
Water discharge measurement in open channels is very important from the water conservation viewpoint. Flow measuring structures are used for continuous mea... P Dutta 被引量: 3发表: 2013年 FLOW OVER SHARP-CRESTED, TRUNCATED-TRIANGULAR WEIRS The present results indicate that (1) truncated weirs de...
The utility model has the advantages of simple structure and convenient operation; the relation between water level and flow rate can be calculated through mathematical model; the difference between measured value and theoretical value can be controlled within 5 percent; the flow measuring accuracy is...
Virtually all ecological processes that occur in wetlands are influenced by the water that flows to, from, and within these wetlands. This chapter provides the “how-to” information for quantifying the various source and loss terms associated with wetla
