Importance of Water Budget Equation

Cover Feature
The Water Balance or Budget Equation can be treated as the mother of all types of hydro-metereological equations.The equation is derived from Law of Conservation of Mass and Energy and states that inflow of water is equal to outflow of the same.If there exist an unequality,then it will contribute to the existing storage of water of the region.Precipitation and Inflows are accounted under Inflow and Runoff,Ground Water Outflow(contributed by infiltration) and Evapo-Transpiration is treated as Outflow.We can find any one of the variables from the equation if the other ones are already known.
Feature 1	Subsurface Return Flow can be defined as that amount of water which ex-filtrate back to the surface after being infiltrated in the up-slope portion of the hill.
Feature 2	Dosear is a new mind map generation tool made exclusively for academic people.It has the features like importing reference from journal papers even from the pdf; automatic suggestions of related manuscripts from the topic of your mind map, etc.Download it from : http://www.docear.org/software/download/

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...
