Table run-off.Most common two kinds of Runoff formations are：Runoff yield under saturated storage pattern and runoff yield excess pattern, two kinds of runoff-generating models are right respectively
Answer respective Runoff calculation method.With deepening continuously for research, different Runoff calculation methods and model are produced therewith.
However, obtaining rainwash by way of calculating, the hydrology base such as substantial amounts of rainfall, evaporation not only need to rely on
Plinth data, and chosen by model, computational methods, water source are divided etc., and series of factors is influenceed, result of calculation meeting and actual conditions
It is inconsistent.
At present, the research of relevant rainwash monitoring is seldom.Compared with calculating, direct measurement rainwash need not be collected
The hydrological datas such as rainfall, are also not required to carry out model selection, calculating etc., can mitigate the workload of hydrologist, save a large amount of
Time.In addition, the rainwash that actual measurement is obtained is more nearly actual conditions, error is reduced, so that follow-up confluxes
Calculation error reduces, and hydrologic forecast is more accurate.
