How can we measure the infiltration rate in the filed? Mention the apparatus used for the measurement.
Digital elevation models are digital representations of x, y, and z locations of points on the surface area of a terrain. These locations are acquired either from a GPS receiver, survey instruments, or aerial or satellite stereo photography depending on the spatial accuracy needed. These digital filRead more
Digital elevation models are digital representations of x, y, and z locations of points on the surface area of a terrain. These locations are acquired either from a GPS receiver, survey instruments, or aerial or satellite stereo photography depending on the spatial accuracy needed.
These digital files of x, y, and z locations are used by the algorithms in a GIS software to transform into either three-dimensional surfaces or elevation contours. It is the GIS software that makes use of this “spatial data.” The output of these algorithms are used for further analyses and calculations.
These could be; calculating cut and fill off of the land under study, 3D visualization of a terrain, watershed and viewshed analyses, and many other civil engineering, infrastructure, architectural and even video games, defense and intelligence-related applications and uses.
Hope this helps.

Generally, for measurement of infiltration on the field we use the Cylindrical Infiltrometer of diameter 30 cm and 60 cm. Basic infiltration rate for a different type of soil are as below: If the infiltration rate is 1-5 mm/hour that it is Clay. If the infiltration rate is 5-10 mm/hour that it is ClRead more

- If the infiltration rate is 1-5 mm/hour that it is Clay.
- If the infiltration rate is 5-10 mm/hour that it is Clay Loam.
- If the infiltration rate is 10-20 mm/hour that it is Loam.
- If the infiltration rate is 20-30 mm/hour that it is Sandy Loam.
- If the infiltration rate is greater than 30 mm/hour that it is Sand.
