Scope

Scope: This document specifies the technical requirements for the working performance of the experimental devices used in urban rainfall runoff experiments, the experimental operation norms, and the data processing methods. This document is applicable to urban rainfall runoff experiments. Main technical content: 3.1 Terms and Definitions The terms and definitions defined in GB/T 50095-2014 and GB 51222-2017, as well as the following terms and definitions, apply to this document. 3.1.1 Rainfall runoff The runoff formed by rainfall. 3.1.2 Experimental research on rainfall runoff Scientific experiments to study the physical mechanisms and variation laws of rainfall runoff and confluence. 3.1.3 Runoff plot A small-area experimental site selected and set up under certain conditions to study the physical processes and mechanisms of runoff formation. [GB/T 50095-2014, Definition 12.2.1.1] 3.1.4 Artificial rainfall device An artificially designed rainfall device that can control rainfall intensity and rainfall type. 3.1.5 Rainfall intensity The amount of rainfall per unit time. [GB/T 50095-2014, Definition 4.3.3] 3.1.6 Rainfall duration The time recorded in the experiment from the start to the end of the rainfall. 3.1.7 Rainfall pattern The process of rainfall amount changing with time during a rainfall event. 3.1.8 Runoff volume The amount of water passing through the flow section within a certain period. 3.1.9 Runoff coefficient The ratio of the runoff depth in a period or sub-runoff to the corresponding rainfall amount. 3.1.10 Sponge facility Engineering facilities with one or more sponge-like effects, such as infiltration, retention, storage, purification, utilization, and drainage, for rainwater. 3.1.11 Underlying surface The water surface on which rainfall in the runoff field occurs. 3.1.12 Impervious area The surface area covered by impervious materials such as concrete, asphalt, and stone.
