![]() ![]() The catchments is subjected to both rainfall and snowfall. In this research the lag time of Jahanbin basin has been determined using spectral density method. A long lag time could be due to snowmelt as well as melting ice due to rainfalls in freezing days. Spectral density under multiple time series could be used to obtain basin lag time for annual runoff and short-term rainfall fluctuation. ![]() In this method harmonically significant quantities with individual frequencies are presented. The time series is approximated with Sinuous and Cosines functions. One of these methods is time series analysis of spectral density. Lag time of basin could be calculated using various methods. Determination of lag time is important parameter in many projects such as dam design and also water resource studies. Quantity of rainfall related lag time depends on several factors, such as permeability, vegetation cover, catchments slope, rainfall intensity, storm duration and type of rain. Lag time has significant role in hydrological studies. Â Â One of the important issues that have significant role in study of hydrology of basin is determination of lag time. The observed etching behavior has been explained in terms of surface oxygen dangling bond density, suggesting that the macroscopic polarity plays a secondary role in the etching process.Īpplication of Time Series Analysis in Determination of Lag Time in Jahanbin Basinĭirectory of Open Access Journals (Sweden) Exotic open-flavor $bc\\ bar undergo homogeneous chemical etching perpendicular to the initial crystallographic plane. ![]()
