The How to Database

There are many hydrologic models available that can be freely downloaded and used to achieve your research objective. However, not all the models will serve your purpose. Some features of those models will be unnecessary for one scholar but may be very useful for other researchers. Even then also more the number of features offered by the model more favorable will it be to the researchers. The frequency of updates will be another parameter that must be included when making a selection among the available hydrologic models. Higher the frequency more preferred it will be. As more updates mean the model is developing itself. The developers are still trying to improve the model functionality, which is a welcome feature of open-source models. The availability of tutorials or help files is another important parameter that is also very influential in selecting a hydrologic model for using in a real-time research problem. Accuracy and reliability are also significant. When the error of the pre...

Before procuring a farm management software(FMS) to convert your conventional farms into smart farms, you must consider the following factors :  1)Number of hydro-climatic and environment factors that can be measured and predicted 2)Procuring cost 3)Ease of use 4)Frequency of Customer support (FCS) 5)Number of features available at the time of procurement. Now all the above five factors are not equally important. Some will be more significant compared to other and also their significance will vary depending on the preference of the decision maker or the user of the software.Here the  ODM  software can be used. In the  ODM  software, write the above five factors as Criteria and name of the FMS as Options.Score the criteria as per  preference and for the options use the data about the selected criteria from the different FMS and rank in the descending order of importance.For example if the FCS of Agrivi is 10 per month and for Farm ERP it is 5 per month then ...

If you use a filter to produce drinking water, it is better to evaluate the source of water and available types of filters before its application.This ppt will show the process of selection of a filter configuration for urban water sources. How to remove pollutants of urban water from Mrinmoy Majumder Click the link here .

How to select the best water filter for your domestic use from Mrinmoy Majumder One of the major requirement for leading a healthy life is drinking pure water from water filters. But often due to a very similar cost and features of different water filters available in the market, the consumers like us get confused about our selection of water filter which will be most usable for our household. This PPT above will show a new way of selecting the most feasible water filter for your own household.

Did you know keeping your lawn the right length can save water? Grass kept at 3 inches tall encourages deeper roots, is healthier during the dry times and can save up to 16-50 gallons of water per day. pic.twitter.com/390pt5FPp5 — Save Our Water (@saveourwater) October 23, 2019 Useful information.

Recently I found a Linkedin video where groundwater was extracted by a seesaw in a school.Its a nice idea as both energy and water is scarce and if we can use the momentum generated due to the movement of a seesaw to replace pumps for extraction of groundwater, then a sufficient amount of electricity can be conserved.  The harmonic motion of the seesaw can be converted into a linear motion of a tube-well to collect ground water.It is totally a zero energy concept which can be implemented where required.As seesaw is inexpensive the entire system will be cost effective.
