Simplified Calculation of Conjugate Water Depth for the Six-arc Egg-shaped Cross Section

LEI Jiaxin;TENG Kai;Heilongjiang Provincial Construction Quality and Safety Supervision Center of Water Conservancy;Qiqihar Municipal Bureau of Water Affairs;  
Conjugate water depth formula of six-arc egg-shaped cross section is segmented and transcendental,it is difficult to calculate directly. Through further calculation of hydraulic jump conjugate depth function of this kind of cross section,dimensionless function of hydraulic jump was obtained,which was represented by the reciprocal of dimensionless area and dimensionless hydrostatic pressure. And then,an optimization fitting method was adopted to fit the reciprocal of dimensionless area and dimensionless hydrostatic pressure,through which the simplified calculation formula that could directly calculate the conjugate water depth before and after the hydraulic jump was established. This formula is simple and intuitive with a maximum error less than 0. 8% in its parameter range of engineering applications.
