Do You Know the Year when the concept of fluid mechanics was introduced ?

Fluid mechanics, an ancient Greek concept, was first introduced by Archimedes around 250 BC. The first law of fluid mechanics, the conservation of mass, states that mass is conserved within a control volume for constant-density fluids. Isaac Newton, an ancient Greek, first described fluid viscosity in his 1687 Principia. The origin of fluid dynamics can be traced back to Leonardo da Vinci, who was educated at Plato's Academy. The Reynolds theory of fluid mechanics explains the relationship between mass and viscosity.

What's New in Hydroinformatics Engineering ?

1 “Flood peaks in Mid-Atlantic U.S. watersheds show a V-shaped response to urbanization: they decrease at low urban development (below 10% PDAW), then rise sharply as urbanization increases further due to complex climate-landscape interactions. A neural network model confirmed this nonlinear behavior, underscoring the need to consider more than just urban area when predicting flood risk.”…..Hua et.al.(2025).

ANN’s superior accuracy highlights its suitability for operational streamflow forecasts in this region.ANN models using lagged climate indices significantly outperformed ARIMA models for forecasting streamflow at Victoria’s stations, especially at Acheron where the ANN achieved Pearson R = 0.90,...

Five most innovative and sustainable water bottles

Cover Feature: Five most innovative water bottles selected by ODM V2 Five most innovative water bottles Water bottles are now becoming smart. Recently launched water bottles have the capability to track your hydration level and can remind you to drink water when the hydration level is below a predefined level. Some water bottles can either increase or decrease the temperature of the water in the container. Some alternatives come with blue tooth speaker/stirrer/fuser/wifi etc electronic devices. Some variation of smart water bottles has the ability to self-purify when needed. Here in this feature, we try to find the most innovative smart water bottles that are available on the eCommerce sites with the help of ODM.
