In Japan, Typhoon No. 15 (Faxai) hit the Kanto region on September 5, 2019, causing massive flooding damage due to collapse of seawalls (Suzuki et al., 2020). Fukuura district Yokohama City, parapet seawall collapsed and large overtopping waves inundated an area 0.75 km inland from seawall, resulting in a flooded 0.8 km2. Since typhoon season lasts until November, there was possibility that typ...

The present paper deals with overtopping prediction for berm breakwaters in line the EurOtop methodology. basis is recent advances proposed conventional respect to influence of wave steepness and crest width. New model tests have been performed investigate applicability these factors breakwaters. To cover a white spot existing data breakwaters, included conditions very low steepness. results sh...

It is widely recognised that microhabitats are important for a variety of marine organisms, yet this knowledge has rarely been applied in the construction of engineered structures as a means of enhancing biodiversity or populations of species at risk. Here we examined the influence of microhabitats on the distribution and survival of the exploited limpet Patella candei on natural shores before ...

Measuring infiltration and leaching at the plot scale is difficult, especially for high hydraulic conductivity soils. Infiltration rate has been indirectly calculated at the plot scale by comparing surface runoff to rainfall. Direct measurement of infiltration and leaching beyond the point scale is typically limited to locations where land forming has been performed, e.g. infiltration ponds and...

On May 23 rd , 2022, an extreme coastal event occurred around the northern coast of Java. This had caused collapsed several seawall segments Tanjung Emas Port, Semarang. Combined with wave overtopping, it led to severe flooding and economic damages port operation. Responding event, this research aimed characterize hydrodynamic condition proposed a design. The was done through field observation,...

The distribution of lead in soil samples collected from both surface (0 to 10 cm) and profile (0 0 to 10 cm, E 11 to 30 cm, Eb 31 to 50 crn, Bw 51 to 100 cm, and C 181 to 200 cm) at a 14-year-old rifle/pistol shooting range located in central Florida were determined using EPA Method 3051a (microwave, HNO/HCI=3:1, v/v). In addition to total lead analysis, Toxicity Characteristic Leaching Procedu...
