Application of Chart Consulting and Formula Method in Flood Calculation of Tailing Pond
The paper systematically explains the calculation processes of flood computation using the Method of Calculation of Storm Runoff by Consulting Chart and Tab.and the Small Watershed Deductive Formula Method.For a tailings dam watershed in a mountainous area of Yunnan,flood calculations were performed according to both the 200-year and 500-year flood protection standards using the aforementioned methods.Analysis of the calculated results showed that the outcomes from the Small Watershed Deductive Formula Method were slightly lower than those obtained through the Method of Calculation of Storm Runoff by Consulting Chart and Table.The calculated flood process using the Method of Calculation of Storm Runoff by Consulting Chart and Tab.was char-acterized by a single peak with a sharp rise and fall,which is consistent with the flood characteristics of moun-tainous rivers in Yunnan.Furthermore,the parameters used in the deductive formula are based on a national synthesis and might not be suitable for that specific region.Additionally,from the perspective of flood protection safety,the results of the calculations using the Method of Calculation of Storm Runoff by Consulting Chart and Tab.are deemed more reasonable.
