Further the large scale modeling results can be used to predict the impact of climate change on coastal aquifer. The performance of the model can be improved by considering the exact groundwater draft from the study area and with fine discretization of model. To evaluate the accuracy and efficiency of the model simulation it is validated with the available groundwater level data from dug wells at the end of 5 year simulation period. The focus of the present work is to simulate the large scale groundwater head and solute concentration for the study area using variable density and solute transport numerical code FEFLOW. Vibratory hammers are typically used to install sheet piles. Permanent steel sheet piles are designed to provide a long service life. The hydrological, hydro-geological and hydro-chemical data are collected from the literature, government sector and institutes. Sheet pile walls have been used to support excavations for below-grade parking structures, basements, pump houses, and foundations, to construct cofferdams, and to construct seawalls and bulkheads. The aquifer is bounded by Arabian Sea on the west eastern side is located along the ridgeline of Western Ghats and the northern and southern boundaries are formed by Varahi and Netravati rivers respectively. The area for large scale coastal aquifer modeling is stretched between the two seasonal and tidal rivers Netravati and Varahi of Karnataka state. ![]() Search 214,006,860 papers from all fields of science.

Therefore, to understand the stress on groundwater resources and interaction of groundwater with seawater in coastal region modeling of large scale heterogeneous aquifer is necessary. Semantic Scholar extracted view of 'Geosynthetic-sheet pile reinforced foundation for mitigation of earthquake and tsunami induced damage of breakwater' by B. The heterogeneity constraint to model groundwater flow and solute transport in the coastal aquifer gives better understanding of seawater intrusion process. Most of the earlier studies on seawater intrusion modeling is simulated for local scale or regional scale, very limited worked has been carried out on modeling of seawater intrusion at large scale around the world. Seawater intrusion into coastal aquifers is a global issue, which is worsening by increasing freshwater draft in coastal regions. The Fast-Form sheet pile capping beam formwork system weighs a fraction of other system, so it’s lightweight and easy to fit, costs less to transport and so dramatically reduces. Studies in the form of groundwater geohydrology analysis with resistivity methods and studies of old river maps at several locations are reported in this paper. The Fast-Form sheet pile capping beam formwork system will reduce our carbon footprint, by over 80 against timber formwork and by up to 1000 vs rival systems. This report presents the results of a survey of several locations affected by the earthquake in the city of Palu on Septem(6:03 pm local time), such as in the Balaroa and Petobo areas. One important element in responding to disasters is conducting comprehensive studies related to the phenomena caused by disasters as study material to understand the phenomena that occur, post-disaster handling and disaster mitigation in the future. This earthquake triggered a tsunami, a shift in the fault (rupture) along the Palukoro fault and its secondary fault, and the occurrence of extensive and massive landslides in the Petobo, Jono Oge, Sibalaya, Balaroa and Lolu villages. Earthquake epicentre is located 72 km north of the city of Palu with an earthquake depth of 10 km. Palukoro fault experienced a strike with a mechanism of "strike slip". Close coordination was required to avoid any disruption of piling work at site.The Palu earthquake with a magnitude of 7.5 Mw occurred on September 28, 2018, at 18:02 WITA time. ![]() Last but not least, our operation team constantly follow-up the whole process, timely update related parties on the progress and coordinate with logistics to bring long length pipes (up to 51 mtr) by barge till to the final site for piling. Due to the ratio of OD and thickness decision was make to use seamless pipe as clutch material, production team had to work closely with main contractor to ensure the quality of the welds and the straightness integrity of the wall.įabrication work was followed by blasting and coating work to ensure corrosion properties in marine environment and lifetime as set by consultant. For the structure to serve the purpose and support the dynamic force of waves and current, a 350 meters pipe wall (Ø 1200*19 mm and up to 51 mtr single length) was fabricated at our plant in Pulau Indah, Malaysia.Īnother challenge for this continuous pipe wall was to use thick and heavy “PP” clutch solution.
