The imminent fear of water-related hazards such as flooding hangs over low-lying areas, in particular now because climate changes have led to increased hazards, like storm surges, that could result in serious harm. This paper aims to provide a novel

Herein, the authors describe an overall approach to the architectural design of floating structures such as floating houses. The primary aim of this study is not to present a method for stabilizing floating structures, but rather to provide a design

The features of two unequal solitary waves during an interaction were experimentally investigated by optical and particle-tracer methods. To estimate the temporal colliding-wave profiles and phase shift during the head-on collision, the water surface

Over the next century or two, rising sea levels and the increased frequency of extensive natural disasters caused by global climate change will bring about serious problems. Such problems are especially foreseen in lower-lying coastal and riverside a

In this paper, we present some theoretical results and we use modern electronic equipment to investigate experimentally rear-end collisions between two solitary waves. The surface position, water-particle velocity, and water pressure of the solitary

We introduce a new concept that utilizes floating foundations to create an urban community base in man-made inlets and basins—an idea that enables the attainment of a prosperous and sustainable urban and rural environment in the long term. This pap

Despite many previous investigations, there is no theoretically justifiable equation to determine the freshwater discharge, tidal velocity, and salinity in a complex estuary that contains several branches. In this study, the longitudinal distribution

Measurements of the characteristics of a solitary wave propagating alone or against a current were performed using superresolution particle image velocimetry (PIV). The velocity field was obtained when the solitary wave passed in front of a high-spee

Summary We investigate changes in geometric characteristics and related processes of the longitudinal salinity distribution in an alluvial estuarine system. We focus on tide-dominated estuaries, which are usually characterized by a convergent shape,
