Abstract This study presents the results of 32 laboratory experiments on local scour at a single pile and 1 × 4 group for both uniform non-uniform sediments under clear water conditions. The present aims to evaluate effects different sediment beds made up mixtures sand gravel (four-bed configurations) in d 50 (1–3.5 mm) gradation (1.4–3) ranges depth flow discharges depths. Further, findings ar...

Bridges when it crossing rivers often required multiple piers for support. One of has a limited investigation is the impact on scouring and morphological aspects bridge sharp-bend river. Consequently, crucial to investigate hydraulic behavior water flow in these areas due presence piers. In present study, an experimental program was conducted laboratory flume featuring two-pier within 180-degre...

The migration of a waved-shape accumulation ice particles under an cover (referred to as “ice wave” in this study) is phenomenon transport during process rivers. wave will affect the pier scour. On other hand, local scour at waves. interaction between waves and around very complicated since not only channel bed deforms, but also jam develops simultaneously. By conducting series flume experiment...

Pier is the second generation of an industrial strength content management and application framework. Pier is written with objects from top to bottom and it is easily customized to accommodate new requirements. Pier is based on Magritte, a powerful meta-description framework. Pier has proven to be very powerful in the combination with Seaside, to enable easy composition and configuration of int...
