Method for judging maximum scouring/silting flow level of runoff riverbed
The invention discloses a method for judging the maximum scouring/silting flow level of a runoff riverbed. The method comprises the following steps that inlet and outlet control hydrometric stations of a research river reach are selected respectively, and the inlet water flow, the inlet sediment transport amount and the outlet sediment transport amount of the research river reach every day are obtained; the average inlet water flow QWm-in, the average inlet sediment transport QSm-in and the average inlet water flow QWm-in of each inlet control hydrometric station in every m days are calculated; the sum of the average inlet sediment transport QSm-in of all the inlet control hydrometric stations in a certain time period and the sum of the average outlet sediment transport QSm-out of all the outlet control hydrometric stations in the corresponding time period are subtracted; and performing Pettit test on an order sequence formed by the scouring/silting intensity QSm of each time period and the corresponding flow level, and determining the maximum scouring flow level or the maximum silting flow level. According to the method, the flow level range of the scour/deposition of the researched river reach and the maximum scour/deposition flow level can be rapidly obtained, and the method has the advantages of being small in data collection difficulty and rapid and visual in judgment method.
本发明公开了一种径流河床最大冲刷/淤积流量级的判别方法。该方法包括如下步骤：分别选取研究河段的各进、出口控制水文站，获取所述研究河段每日的进口水流量、进口输沙量和出口输沙量；计算各进口控制水文站每m天的平均进口水流量QWm‑in、平均进口输沙量QSm‑in和平均进口水流量QWm‑in；将各进口控制水文站在某时间段内的平均进口输沙量QSm‑in之和与各出口控制水文站在对应时间段内的平均出口输沙量QSm‑out之和求差；对每个时间段的冲刷/淤积强度△QSm与对应流量级组成的秩序列进行Pettit检验，确定最大冲刷流量级、或最大淤积流量级。本发明能够快速得到研究河段冲刷/淤积的流量级范围、以及最大冲刷/淤积流量级，具有资料收集难度小，判别方法快速、直观的优点。
