Five Most Popular English Movies (Fiction) on “Climate Change and its Impacts on Water Resources”

Students working in the field of climate change and water resource modeling often complain that they can’t see what they are predicting. They are confused about the reliability of their models and depend on some statistical indices to analyze the accuracy of their predictions. But if they want to have an idea about the reality of their predictions then they must watch the following five movies which simulate the future based on one or more climate change based impacts:.....

7 most recent application of GIS in the identification of suitable location for rain water harvesting

The water crisis has been rapidly increasing these days in many parts of the world which emphasize the importance of refinement in water management systems. Harvesting of rainwater(or rainwater harvesting(RWH)), which involves the collection and storage of rainwater for future use, is an area of increasing interest and one of the most suitable measures for ensuring water availability in the future days. The location of RWH is of utmost importance for the success of the water harvesting project. Locations for the construction of RWH structures like check dams, percolation tanks, bench terraces, contour ridges, and contour bunds can be determined by the application of Geographical Information System(GIS), Multi-Criteria Decision Making(MCDM), and different predictive models. Below are the seven recent case studies which demonstrate the procedure of location selection for RWH. 1) Case Study of Kiambu County-Kenya The ideal sites for five rainwater harvesting structures (bench terraces, ch

Seven New Runoff Prediction Models

Runoff Prediction Models Runoff Prediction Models(RPM) are those models which predict the runoff or flood peak of a watershed or input runoff to a dam etc. Generally, such models require climatic parameters, geomorphology, soil characteristics, and land cover as input against which a runoff model can predict the monthly, weekly, daily, or even hourly runoff. These models can be spatially distributed or lumped, temporally long or short, data-driven or conceptual.  In recent years due to the massive development in data-driven and smart concepts like artificial neural networks(ANN), decision trees, and evolutionary algorithms, application of such techniques are now common to develop RPMs. Among data-driven techniques, ANN is the most popular, followed by evolutional algorithms. But compared to the standalone application of neural networks, hybrid models where ANN with conceptual models like HyMOD or HEC is found to be more successful. Hydrologic models like RPMs need to be calibrated and

Five Most Innovative Rain Water Harvesting Projects

Rainwater harvesting is known to be one of the most prominent solutions to the impending vulnerability of many watersheds all over the world due to climate change impacts. The rejuvenation of the watersheds with the help of innovative rainwater harvesting can prevent further deterioration of the basins. Below are the five most intelligent water harvesting methods adopted by the stakeholders to restore their watersheds which ensured their sustainability. Mega muddy rainwater harvesting System/project "Harvested water is used for fish farming, banana plantation, Sericulture, Floriculture and for other purposes." Story of Dhun "the first step for his dream project was to bring water to this dry land and using traditional water harvesting practices the land today has more than 8 waterbodies in it..." Rain Water Harvesting in Kenya, Ethiopia, and Uganda "There is hardly a place in the world where it never rains. Rainwater belongs to everyone. And the methods to coll

Water Conservation in Satara : Case Study


See the video or Download the clickable version The process of forecasting the rainfall after two or less than two-hour is known as Rainfall nowcasts(RN). The model which predicts such a very short-term storm is referred to as the Rainfall Nowcasting model (RNM). Due to the high amount of variability involved the development of accurate nowcast models is a challenging task. Due to the increase in climatic variability and urbanization, the need for such models for the design and development of accommodative infrastructures is increasing. That is why five of the most important research topics related to rainfall nowcasting are delineated below : @Mrinmoy's Page Share your data requirement , @Merchandise or @ Shop Add to Listy

Five most promissing topics of research in Building Induced Rainfall Redistribution(BIRR)

BIRR is referred as the impact of impervious areas on the distribution of water after rainfall. The area, type, and texture of various impervious areas like buildings, pavements, roads, etc. do not allow rainfall to infiltrate the soil cover and enforced the water droplets to flow off the watershed as runoff. The impact of buildings on rainfall redistribution and its effect on water availability can yield interesting and useful research proposals. Five of which are listed below: Impact of BIRR on flood forecasting models Impact of BIRR on hydrologic response Impact of BIRR on desertification Impact of BIRR on water quality Impact of BIRR on watershed vulnerability Click here to download the entire report  or view the video below : Available in Slide share mode also. @Mrinmoy's Page @Merchandise or @ Shop Add to Listy

How to apply optimization techniques to water resource problems?

"Maximizing or minimizing some function comparative to some set, often demonstrating a range of choices available in a certain situation. The function allows evaluation of the different choices for determining which might be “best.”....Definition of optimization. In optimization, we try to maximize/minimize/achieve a target value by changing some variables of an objective equation. Optimization is used to solve problems in a multidisciplinary field including water resources. The problems like solving multi-reservoir optimization, water allocation problems, economic optimization of water-based systems, performance optimization of water treatment plants, etc. can be easily solved by the application of various classical and new optimization techniques. If you search on the internet, especially through Sciencedirect or Springer Portals you will find multiple papers on the Optimization Technique and its application to water resource problems For example, the following are some of the c

How to use GIS for detection of Leaks in Pipelines ?

View Slide Show Leak detection in pipelines is a common problem faced by residential complexes, industries, office complexes, and also in simple single-storied houses. If you know how to use GIS to detect that leak then it will be easier for you to fix it.

Five examples of Water Collected from Air

Video Link : 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

Five new ideas for launching agro-start ups

View the image  in original size Agricultural output controls the GDP of a Country. Especially the developing countries largely depend on its agriculture productivity to enhance their socio-economy and livelihood of the local population. Sustaining the profitability of cultivators is one of the major objectives of any government. Water and energy which are the two drivers of agriculture need to be optimally utilized. The uncontrolled and uneven distribution of natural resources, especially water resources, often compromises the agricultural productivity of the water-stressed regions of a country which in turn affects the national GDP of that country.  So optimal management of water and also energy resources in an agricultural location can ensure stability and incrementation of GDP of the country. That is why some apps can be developed and offered commercially to the farmers which can help in not only maximization of agricultural productivity but also it will help in the smart managemen
