- 摘要:
- 为做好小流域山洪强降水天气预警,利用2013-2014年巴南跳石河水位和雨量资料,研究巴南跳石河单站雨量与水位的关系,计算致灾临界雨量和水位。结果表明:跳石河水位和提前5～11 h的单站累计雨量,相关系数较好,通过了0.01显著性水平检验,并得出相对水位和5 h累计雨量的关系式。最后,根据跳石河河道普查资料和中国气象局山洪灾害风险等级标准,利用雨洪关系式调整参数计算出2个标准的临界雨量,这些指标可以用于跳石河山洪灾害的检验和预警。
- Abstract:
- In order to handle the warning of heavy rainfall in small watersheds, the author researched the relationship between the rainfall and the water level of single station, which is based on the data of the water level and rainfall of the Tiaoshi River from 2013 to 2014. And then the author calculated the critical rainfall and water level.The results showed that: the water level and the cumulative rainfall of 5 to 11 h in the first half of the river and the correlation coefficient are good, and it passed through the test of the significance of the level of 0.01, and the relationship between the relative water level and 5 h cumulative rainfall. Finally, according to the census data and jump stone river flood disaster China Meteorological Bureau risk grading standards, the use of rainwater relation adjustment parameters to calculate the critical rainfall of 2 standard, and these indicators can be used to check and stone mountain flood disaster warning jump.
