Description
Technical field
The utility model relates to a kind of rainfall runoff measuring instrument, especially hillside point rainfall runoff measuring instrument.Belong to hydrologic forecast field of measurement in the hydraulic engineering.
Background technology
The massif district area that China is threatened by mountain flood is about 4,630,000 km
2, accounting for 48% of China's land surface, total population is about 5.56 hundred million in the district, accounts for 44.2% of country's total population.Because the mountain area area is than great, have a large population, so the casualty loss that mountain torrents cause is often very serious, cause for the sustainable development of China's mountain area national economy and have a strong impact on.In recent years, great rivers freshwater monitoring level, flood control standard progressively are improved, no matter and small watershed in mountain is freshwater monitoring, or the flood control standard of the non-engineering of engineering is all lower.For this reason, " national mountain flood control program " will " tentatively building up mountain flood keypoint control district serves as the main system of preventing and reducing natural disasters that combines with engineering measure with non-engineering measures such as forecast, early warning " as recent (2010) object of planning.
The hillside hydrologic process occupies critical role in hydrology circulation.Research shows: in the massif district, account for 95% (Kirkby, 1988) of total amount via the water yield in entering river course, hillside fields.In addition, hillside hydrology development in recent years numerous theoretical methods, like Representative Volume Element basin (REW) theoretical (Reggiani; 1998), the threshold concept of hillside runoff yield (Tromp-van Meerveld; 2006a & b) and the hillside amount of holding kinetic theory (Troch, et a1., 2009) etc.Should, theoretical foundation needs the new observation procedure and the support of research technique, and this is (Beven, 2006 of relatively being short of at present; Hu and equality, 2007).Therefore, effectively monitor hillside rainfall runoff process, for understanding with understand hillside hydrodynamic force process, and the method etc. of setting up the prediction mountain torrents all has important significance for theories and engineering practice value.
Make progress from present correlative study both domestic and external, in the prior art of hydrologic forecast and hydrometric station monitoring, numerous for equipment and method that streamflow regime in rainfall and the river course is monitored.The hydraulics model test research of existing hillside mainly comprises two class methods (Gu Weizu etc., 2010): the one, and antificielle hillside and rainmaking test method; The 2nd, open-air in-situ observation test method.The defective of these two kinds of methods is, cost is high, the cycle is long and uncertain big etc.Because the diversified restriction of underlying surface and measure the restriction of means, there is not perfect method that the runoff yield water yield and the spatial variability thereof on hillside, the upper reaches, basin goed deep into experimental study always.Therefore, a kind of can monitoring point yardstick hillside rainfall, the equipment and the method for overland flow, interflow etc., be the basis that above research is deeply gone down.
