2. What is the peak flow runoff coefficient
The peak flow runoff coefficient is a quantitative indicator of the proportional relationship between the maximum instantaneous flow during a flood flow process and the runoff formed by rainfall or snowmelt. A detailed explanation of the peak flow runoff coefficient is given under the guidance of Qiqichen. The definition of peak flow is instantaneous maximum value, which refers to the maximum instantaneous value reached by the flow during a flood flow process. Measurement and Calculation: This value may be obtained through actual measurement, calculated using the water level flow relationship curve, or calculated using hydraulic formulas. The meaning of runoff coefficient: proportional relationship: runoff coefficient is usually used to describe the proportional relationship between the runoff formed by rainfall or snowmelt and the total precipitation. However, in the context of peak flow, the runoff coefficient can be extended to refer to one of the factors that affect the magnitude of peak flow, namely the efficiency of converting rainfall or snowmelt into river flow. Influencing factors: The runoff coefficient is influenced by various factors, including soil type, vegetation cover, topography, and rainfall intensity. The relationship between peak flow and runoff coefficient: correlation: Although peak flow and runoff coefficient are two different concepts, they are closely related. The magnitude of the runoff coefficient directly affects the peak flow rate of the beam. Under the same rainfall conditions, the larger the runoff coefficient, the more rainf
3. What is peak flow
Peak flow refers to the maximum instantaneous flow during a flood process, that is, the flow value at the highest point on the flood process line.
. The following is a detailed explanation of peak flow:Definition and Characteristics Definition: Peak flow is the maximum value reached by a river during a flood event, representing the peak flow of the flood process.
. Unit: usually expressed in cubic meters per second (m ³/s).II. Cause of formation rainstorm or snow melting: when rainstorm or snow melting occurs, water bodies (such as lakes, reservoirs, soil, etc.) in the basin will quickly absorb and transform into runoff. Runoff convergence: These runoff gradually converge into the river channel according to their distance from the channel and the order of their formation time. With the continuous inflow of upstream runoff, the river flow begins to increase. Peak flow: When most of the high-intensity runoff in the watershed flows into the river channel, the river flow will reach a maximum value in Biyan, which is the peak flow.
