Hydrology Tutorial on Flood

Floods refer to the overflow of water onto normally dry land, often caused by heavy rainfall, melting snow, or dam failure. They can cause significant damage to infrastructure, agriculture, and human settlements. Studying floods is crucial as it helps us understand their causes, patterns, and impacts on both the natural environment and human societies. This knowledge enables us to develop effective strategies for flood prevention, mitigation, and response, ultimately saving lives and minimizing economic losses. Click here to see the tutorial.

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...

Internship Opportunity at NIT Agartala - "Game theory meets flood resilience: play smart, protect lives."

This internship offers a unique opportunity to apply game theory to real-world flood resilience , equipping participants with strategic decision-making skills that go beyond traditional hydrological modeling. Interns will: ✅ Gain hands-on experience in stakeholder analysis and strategic modeling. ✅ Develop decision-support frameworks that balance cost, risk, and social feasibility. ✅ Work on case studies to bridge theory with practical flood mitigation strategies. ✅ Enhance interdisciplinary expertise , combining hydrology, economics, and policy dynamics. ✅ Build problem-solving skills that can shape future disaster resilience planning. By the end of the program, interns will have a deeper understanding of flood management complexities and a powerful toolkit for strategic problem-solving —essential for careers in hydroinformatics, environmental policy, and infrastructure planning. 🌊🎲 https://www.facebook.com/share/v/1QK714yR1u/ You may also like : HydroGeek: The newsletter ...

Five examples of Water Collected from Air

Video Link : https://youtu.be/AVQJCH-6psg Water from Air is a new concept for the conservation of water by adopting a source that is uncommon and renewable. The most abundant source of freshwater is the Earth’s atmosphere. When atmospheric humidity condenses, it falls as rain. This natural process of condensation is replicated by adopting different technologies, which allows it to make water continuously, even in low humidity conditions. Here are the examples : 1) Airowater Dewpoint Smart "The Airowater Dewpoint Smart is one of the smaller units designed to ensure portability. This unit can make up to 20 litres per day in relative humidity and is also equipped to use city water as the input source to deal with a sudden increase in demand!" 2) Rainmaker "Rainmaker’s Air-to-Water units produce drinking water from the air – no other water source is required. " It uses a turbine that forces air through a heat exchanger, where the air is cooled and condensation takes pl...
