Title:
METHOD FOR ANALYZING HYDROLOGICAL REGIME CHANGES IN INBOUND AND OUTBOUND RUNOFF
Document Type and Number:
WIPO Patent Application WO/2022/217567
Kind Code:
A1
Abstract:
In order to overcome the defect of hydrological regime changes, which are caused by the difference between the inflow and the outflow of a reservoir, upstream and downstream of the reservoir affecting research on actual hydrological regime changes in rivers, a method for analyzing hydrological regime changes in inbound and outbound runoff is proposed in the present invention. The method comprises the following steps: collecting an inflow data sequence and an outflow data sequence, and determining hydrological years of inbound runoff and outbound runoff; calculating parameters required for classifying IHA low flow and IHA high flow in inflow data, and EFC classification parameters for the inflow data; applying the parameters required for classifying IHA low flow and IHA high flow and the EFC classification parameters to outflow data, and respectively calculating IHA parameters and EFC parameters of the inbound runoff and the outbound runoff; and according to the IHA parameters and the EFC parameters of the inbound runoff and the outbound runoff, analyzing hydrological regime changes in the inbound and outbound runoff by using the range of variability approach (RVA) of IHA.
