    Lag is the delay between the time runoff from a rainfall event over a watershed begins until runoff reaches its maximum peak. Conceptually, lag may be thought of as a weighted time of concentration where, if for a given storm, the watershed is divided into bands of area (fig. . Fig. Effective rainfall (8) = (1) - (4) - (5) - (7) In other words, the effective rainfall (8) is the total rainfall (1) minus runoff (4) minus evaporation (5) and minus deep percolation (7); only the water retained in the root zone (8) can be used by the plants, and represents what is called the effective part of the rainwater.

One study concludes that about 60 percent of the rain and snow that falls over land comes from moisture originating from the oceans, and the other 40 percent is “recycled” over the continents. China, for example, gets most of its rain and snow from evaporation over Eurasia.

The rainfall runoff is one of the most frequently used events in hydrology. Numerous methods have been developed by different researchers to simulate the rainfall runoff process. Firstly, a relationship between direct runoff and the mean a real rainfall was developed and validated using statistical model.

Hydrograph is a diagram showing Debi changes to time; if we have a rainfall of t hours on a basin with a concentration level of tc hours and t>xc, Debi will gradually increase and reach the peak in a time less than concentration time (tc).

Then, till it continues and the amount of runoff remains fixed and after it. Since the last update inthere have been many developments in the understanding of rainfall-runoff processes and many new tools available for catchment simulation. ARR takes advantage of the significant advancements in computer technology, techniques and understanding of rainfall-runoff processes since and introduces changes to.

Rainfall-Runoff Processes Chapter 1: 2 tables, spatially concentrated rainfall on a small area may generate local runoff that then infiltrates downriver, whereas a more humid area with shallow water tables is less likely to be subject to stream infiltration losses and even gentle rainfall when widespread and.

The computed maximum rate of runoff to the design point is a function of the average rainfall rate during the time of concentration to that point. The hydrologic losses in the catchment are homogeneous and uniform. The runoff coefficients vary with respect to type of soils, imperviousness percentage, and rainfall frequencies.

Authors: WK LEWIS Source: Proceedings of the Institution of Civil Engineers, Volume 8, Issue 1, 1 Sep (17–52). Intensity of Rainfall (i) Intensity of rainfall is defined as the amount of ppt per unit time expressed as depth of water per unit time (mm/hr, inch/hr).

It has been observed that intensity of rainfall for a short period rain fall is greater than that of long duration rainfall. Maximum flows are produced by short duration rain.Rainfall-runoff modelling – comparison of modelling strategies with a focus on This work is an integrative study of methods for rainfall-runoff simulation.
