... ABSTRACT This paper introduces an integrated system comprising a UAV mounted with a spectroradiometer, which is capable of collecting reflectance and parameters of water quality simultaneously. Reflectance and parameters of water quality, such as chlorophyll-a and turbidity were collected...

... gauges. Sediment suspension process induced by waves can be captured by cameras, as well as the morphological change of sandbar. Meanwhile, an Optical Back Scattering (OBS) is set about 3m behind the sandbar to record the turbidity caused by the wave. The sandbar evolution were quantitatively obtained...

... to locate monitoring equipment. The results obtained include images of plumes, turbidities, particle size composition, the distribution and time-series variations in the amount of resediment and its chemical compositions. INTRODUCTION Generally, SMS are rich in high-quality base metals (copper, lead...

... Abstract Benten River has a floodgate for disaster prevention. We have investigated the effect of the water supply from Benten River due to the floodgate opening on the water qualities in Shido Bay. Average values of salinity, turbidity and chlorophyll a to the deep direction at the inner bay...

... sensor was developed that can be used on the site where drilled shafts are used, and then a verification test was implemented. In the test, the levels of salinity, temperature, and turbidity were changed by reproducing the environment when there is water in a borehole. It was found that the sensors had...

... Offshore Industrial Park (YOIP), the largest industrial park in Taiwan, since 2006 to provide real-time water quality information such as pH, ORP, water depth, dissolved oxygen, temperature, turbidity, conductivity, and chlorophyll. To interpret the large quantities of high-frequency data generated...

... resuspension largely depends on the dredging technique adopted. In the grab dredges, the operation of a bucket controls the dispersion of dredged material. This paper discusses the relationship between operating conditions and the turbidity cased by grab dredge using the watertight bucket at the closed water...

... ABSTRACT Performance of silt-curtain in three dimensional sea is investigated through a series of experiments. It is found that there are three mechanisms to reduce concentration and flux of turbidity generated by the construction work from flowing out of the construction site enclosed...

... A laser imaging system was designed and fabricated for optimum performance in highly turbid (less than one meter visibility) coastal, fiver, and lake waters. The system uses coherence gating and heterodyne detection. The laser source is a compact 683 nm semiconductor laser with an external...
