The study examines the shoreline (1990–2019) and nearshore morphological changes (seasonal) to understand littoral drift sediment budget variability. Shoreline change rate depicts erosion (− 0.06 m/year) in northern sector accretion (+ 0.12 southern sector. Seasonal from non-monsoon monsoon period signifies net 1.8 × 104 m3) 2.5 Although lost during is regained period, quantity of gain reduced ...
Sediment rating curve is an essential factor for many river engineering subjects and computations such as dredging, design of storage dams, river intakes design and sand mining management. Although, this curve is established using simultaneous measurement of flow and sediment transport discharges, however, due to lack of reliable data during flood events, it has limited reliability in flood con...
The Northwest Portuguese coastal sector Esmoriz-Nazaré is exposed to a very energetic wave climate that promotes net littoral drift estimated be around 1.1x106 m3/year. This study aimed characterize the in Esmoriz-Nazaré, discussing past and future trends by applying two bulk longshore sediment transport formulas: CERC (1984) Mil-Homens et al. (2013). Generically, results present variability at...
This document contains information about the fundamentals of beach profiles and is intended to help teachers improve their content knowledge of ocean wave forces and coastal geomorphic response. Background addresses some of the basic information about waves and the beach profile. Methods of Measuring Beach Profiles presents the history of how coastal scientists have developed techniques of meas...
Varied flows such as flooding resulting from dam break can happen due to earthquakes, seepage, bombing, overtopping, mistake in design and project performance as well as causing financial damages and human losses. Unsteady flow during flooding events has a high impact on flow field pattern, sediment motion, ecology and also, distribution of contamination in the river. In this study, the impact ...
