Lakes are a common water resource. This study analyzed residents’ concerns regarding their lake environments to help solve lake environmental problems. The study area comprised three lakes in Japan—Kasumigaura, Suwa, and Biwa—which have different tendencies to change in water quality. A sample of 1200 respondents was evenly distributed among the three lake regions. A questionnaire survey asked about...
It is crucial to monitor light environments in large lakes using satellite remote-sensing data. Many studies have proposed prediction schemes of transparency information, but most of them were site-specific. Here, we applied semi-analytical retrieval procedures of inherent optical properties from in situ-measured remote-sensing reflectance and then predicted the Secchi depth (SD) using contrast transmittance...
