WebO Initial infiltration capacity O Equilibrium infiltration capacity O Constant infiltration O None of the choices O Phi index As described in the figure below, the infiltration method is performed by finding the loss difference between gross precipitation and observed surface runoff measured as a hydrograph (discharge vs. time curve). Weban infiltration index is used which assumes infiltration to be constant through time (at mm hr-1). • The φ-index is defined as that rate of rainfall above which the rainfall volume equals the runoff volume. The φ-index is relatively simple and all losses due to infiltration, interception and depression storage (i.e., storage WebJul 29, 2024 · This video describes rainfall abstractions (interception, infiltration, and depression storage).

WebMETHODS AND EQUIPMENT Infiltration rate usually is determined from field data. Many dif ferent methods and types of equipment have been used for measuring infiltration rate, but the principal methods are flooding of basins or furrows, sprinkling (to simulate rain), and measuring water entry from cylinders (infiltrometer rings). WebPhi Index method The simplest method of estimating infiltration rate and is calculated by finding the loss difference between gross precipitation and observed surface runoff measured as hydrograph.
