Abstract High-frequency seismic data on Mars are dominated by wind-generated lander vibrations, which radiated partially to the subsurface. Autocorrelation functions (ACFs) of filtered between 1 and 5 Hz show clear phases at ∼1.3, ∼2.6, ∼3.9 s. Daily temporal changes their arrival times (dt/t) correlate well with daily ground temperature, ∼5% variation ∼50 min apparent phase delay. The followin...

daily discharge data of 12 hydrometric recording stations in atrak river basin were manipulated to calculate low flows for 7-day duration for studying hydrological drought using regional analysis method. using regression models, the low flows for 7-days duration of 10-year return period were calculated and regional low flows were estimated for 20 stations. daily data in each station used to sim...
