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. Now let us continue with the regular features : News about Sustainability Audi e-tron's used batteries in e-rickshaws by Nunam A new study finds inactive yeast could be effective as an inexpensive, abundant, and simple material for removing lead contamination from drinking...

Five open source free hydrologic models that you can use to model runoff of micro to macro watersheds

The principal objective of hydrologic models is to forecast the runoff of a surface water body, especially dendritic systems like rivers, streams, etc. The inputs to these models are generally Rainfall/Precipitation, Soil Characteristics, and other Climatic parameters like evapotranspiration, humidity, etc. LULC and geo-morphology are also used as the required input parameters of the hydrologic models. Both input and output of these models are temporally as well as spatially variable. Now the resolution varies with different models. Some models consider all the sub-basins to be a single watershed and determine the output based on the characteristics of this single watershed(lumped).In contrast, some other models will consider the {impact|effect} of each of the sub-basins on the central outflow of the watershed(distributed).In a few models, the entire watershed is divided into grids or units of uniform dimension. However, the accuracy is highest for the models, which considers the {impa...
