“…A rubber weir is a rubber bag that is installed across a river or water channel to raise the water level so that it can be used to irrigate irrigation channels, provide raw water or as a means of controlling floods (Pranida 2022). is also encouraged to create added value and sustainable development so that the benefits of infrastructure can be felt by future generations (Gao et al 2022).…”

Rembang Regency is one of the areas in Central Java that often faces the problem of lack of clean water, especially during the dry season. One of the innovations that can be applied to overcome the problems in Rembang Regency is to make a rubber weir. This study aims to consider and choose the location of the rubber weir which is planned to be built in the Kaliori District. There are 6 (six) criteria used in considering the selection of a rubber weir location and 3 (three) alternative location of weir. The data is then processed using the Analytical Hierarchy Process (AHP) method. The results showed that the most important criteria started from the ease of operational access (0.260), seawater intrusion (0.197), topographic considerations (0.161), social aspects (0.136), distance from water management installations (0.129), and the importance of fishing boats (0.117). As for Location 3, which is 300 m near the Dukuh Mbancang bridge, Tambakagung Village is the best alternative to be the location for the construction of a rubber weir. This is because the location has a straight river path and easy access and does not interfere with fishing activities.

“…The elastic modulus and thickness of the membrane material are measured with their magnitudes of 4 Â 10 6 kPa and 4.0 Â 10 À5 m, respectively. The adapted length of the beam element is 4.55 Â 10 À3 m. The contact normal and shear stiffnesses are assumed as 1 Â 10 6 and 5 Â 10 5 kN/ m, respectively, by referring to the studies conducted by Huong (2001) and Gao et al (2022). All the parameters adapted in the numerical studies are summarized in Table 2.…”

The air-inflated rubber dam is innovatively adopted in this paper for temporary flood-fighting at the subway entrance. Numerical studies using the FLAC 2D software are carried out to investigate the behavior of the proposed structure. Laboratory model tests are also conducted to verify the accuracy of the numerical model. The results from the model tests agree well with those from the numerical analysis. Parametric studies are carried out to investigate the influences of the external floodwater head, inflated air pressure, and anchor position on the performance of the proposed air-inflated rubber dam. It is found that the external floodwater head reduces the tensile force but nonlinearly increases the height of the rubber dam. The inflated air pressure has no obvious effect on the cross-section of the rubber dam but heavily influences the ultimate flood-fighting height and tensile force. An optimum design line for the inflated air pressure of the rubber dam is provided. A deeper anchor position results in a smaller ultimate flood-fighting height. A rubber dam design with a lower anchor depth that has to satisfy the requirements of the anchor bolt is therefore concluded.
