Arrangement of watershed from overflowing lookout applying the SWAT prototypical and SUFI-2 (case study: Kasiliyan watershed, Mazandaran Province, Iran)

Overflows are an ordinary singularity that origins substantial fatalities of lifecycle and possessions and anthropological civilizations each time and persons have recognized it as a predictable occurrence. In this investigation, to forecast the overflowing in Kasiliyan SWAT hydrological prototypical was applied. Evidence wanted to be this investigation, with topographical maps, terrestrial usage, soil information, and climatological information, information about steady precipitation, temperature, and current degree were organized earlier. SUFI-2 database was applied for prototypical standardization. Subsequently the standardization and optimization of the prototypical, justification of the prototypical in the study zone was completed. The standardization of the prototypical was done from 2004 to 2010 and corroboration was completed from 2011 to 2014. To examine the consequences of arithmetical gauges R-2, bR(2), and Nash Sutcliffe constant were applied. Afterward prototypical standardization the particular constants were 0.79, 0.66, and 0.79 and the individual corroboration constants were 0.79, 0.76, and 0.71. The sensitivity consequences of 25 components that are important on overflow aquatic displayed that static components of groundwater improper current, its period, and the smallest quantity of aquatic essential for groundwater improper current are more complex than other components. Quantity Kasiliyan component curvatures were applied for overflow washbasin. Kasiliyan washbasin was separated into 24 zones to investigate the overflowing design. Lastly applying the overhead professed Mockups, it was decided that sub basin number 7 had the primary-rank with runoff 128.06, sub basin number 12 had the next rank with overflow in relations of overflowing and sub basin number 2 with a 12.62 has the minimum quantity of overflow.

Automated summary

In this investigation, the Kasiliyan SWAT hydrological prototype was used to predict overflowing occurrences. The prototype was standardized and optimized, and its validation in the study area was completed. The sensitivity analysis revealed that static components, such as groundwater improper current and its period, have a greater impact on overflowing than other factors. Based on the model findings, the sub basin number 7 had the highest runoff, while sub basin number 2 had the least amount of overflow.
