The water cushion depth of stilling basin with shallow-water cushion is a key factor that 13 affects the flow regime of hydraulic jump in the basin. However, the specific depth at which the 14 water cushion is considered as “shallow” has not be stated clearly for now, and only conceptual 15 description is provided. This paper attempts to specify the best water cushion depth based on the 16 flow...

This research was prepared as a preliminary laboratory study to achieve moving hydraulic jump with controlled discharges. It is an initial part of the that being treat salt tide occurring in Shatt al-Arab due lack water imports were coming from Karun and Karkheh rivers Iranian territory, this scarcity caused affected significantly environmental reality city Basra agricultural lands surrounding ...

Oscillating type devices constitute a major class of offshore wave energy converters. In view of the characteristic of the wave energy in China that is low in energy density, a new heaving buoy wave energy device is designed. The paper introduces the basic components of the device, including buoys, support platform, submerged platform, anchor system and hydraulic power take-off, addresses the s...

Partially invariant solution to (2 + 1)D shallow water equation is constructed and investigated. The solution describes an extension of a stripe, bounded by linear source and drain of fluid. Realizations of smooth flow and of hydraulic jump are possible. Particle trajectories and sonic characteristics on the obtained solution are calculated. 1. Construction of the solution. Equations describing...
