Abstract—Local irregular topography has a great impact on earthquake ground motion. For scarp topography, using numerical simulation method, the influence extent and scope of the scarp terrain on scarp's upside and downside ground motion are discussed in case of different vertical incident SV waves. The results show that: (1) The amplification factor of scarp's upside region is greater than tha...
When performing forward modelling and inversion of Magnetic Resonance Sounding (MRS) data, the water-content distribution is typically assumed to be horizontal (1D case). This assumption is fully justified because MRS is often used for characterizing continuous aquifers in a nearly flat environment. However, MRS can also be used in areas with sharp topographical variations. Following a review o...
Introduction The human need for energy is continually increasing and the limited sources of fossil energy are reducing. The indiscriminate use of fossil fuels pollute the environment and threaten life on the earth. Besides, because of difficult terrain, unfavourable topographical conditions and inaccessibility of some mountainous roads to national electricity network or high costs of these s...
چکیده مطالعه ویژگی های مورفولوژیکی ، میکرومورفولوژی، فیزیکوشیمیایی و کانی شناسی خاک ها در یک ردیف پستی و بلندی در منطقه کوهین قزوین پریسا حسینی برای حفظ اراضی و افزایش امکان بهره برداری از خاک، آگاهی از ویژگیهای مختلف خاک ها ضروری است. در این تحقیق ویژگی های مورفولوژیکی ، میکرومورفولوژی، فیزیکوشیمیایی و کانی شناسی خاک ها در یک ردیف پستی و بلندی در منطقه کوهین قزوین در شهرستان قزوین مطالعه و ...
[1] We find that the standard deviation, hence error, of the water surface elevation data from the Shuttle Radar Topography Mission (SRTM) is 5.51 m for basin-wide, regional and local Amazon mainstem reaches. This error implies a minimum reach length of 733km in order to calculate a reliable water-surface slope. Resulting slopes are 1.92 ± 0.19 cm/km for Manacapuru, 2.86 ± 0.24 cm/km for Itapeu...
Measurements from the Near Earth Asteroid Rendezvous (NEAR)-Shoemaker Laser Rangefinder (NLR) indicate that asteroid 433 Eros is a consolidated body with a complex shape dominated by collisions. The offset between the asteroid's center of mass and center of figure indicates a small deviation from a homogeneous internal structure that is most simply explained by variations in mechanical structur...
A 3200-kilometers-long profile of Mercury by the Mercury Laser Altimeter on the MESSENGER spacecraft spans approximately 20% of the near-equatorial region of the planet. Topography along the profile is characterized by a 5.2-kilometer dynamic range and 930-meter root-mean-square roughness. At long wavelengths, topography slopes eastward by 0.02 degrees , implying a variation of equatorial shape...
