| Outline of Final Research Achievements |
In recent years, the increased incidence of sudden heavy rains in Japan has enhanced the occurrences of surface runoff from sloping farmlands. These runoff events negatively affect the ecosystems due to leaching of fertilizer components and/or heavy metals into local watersheds. Water-level meters installed at the bottom edge of sloping farmlands have been conventionally used for measuring the extent of surface runoff. However, data provided by this equipment are unreliable because of the direct contact of sensors with various objects, such as pile-ups of crop residues and/or soil particles. To avoid this disadvantage, we herein propose a novel method that uses automatically captured time-lapse images of surface runoff.
