How to use Goodrich Flood Routing Method for Predicting Outflow Hydrograph of a Reservoir ?

A mathematical method called the Goodrich Method of Flood Routing is used to forecast how much water would flow through a river or channel during a flood. When determining the downstream water flow rate, the channel's geometry, roughness, and slope are all considered. With the use of this technique, hydrologists and engineers can better evaluate the possible effects of flooding and decide how best to safeguard infrastructure and populations. It makes more precise flood prevention measures possible by properly predicting the behaviour of water under different situations. In order to better inform strategies for sustainable development, the Goodrich Method also evaluates how land use patterns affect the likelihood of flooding. It is a flexible tool for planning for and responding to disasters.

How to calculate Water Quality Index considering the source type,intended use and climate ?

This WQI's primary innovation is that it calculates the WQI based on the type of source from which water is collected, the WQI's intended use, and the local climate at the time the samples were retrieved. The source or location from where the sample is collected has an impact on the quality of water which the index must incorporate at the time of calculation. The purpose for which the water quality index is calculated changes the weightage of the importance of the different quality parameters. For example, if WQI is calculated for knowing how drinkable the sample is then the weightage of coliform will increase compared to other parameters as the presence of coliform in the drinking water can not be permitted. The climate of the area from where the water is collected is another criterion to consider at the time of calculating the WQI. Based on the climate also the weightage of water quality parameters will vary. There will be a difference in the weight of importance if the sampl...

Five Most Extreme Hydrologic Events that changed the World

Typhoon Tip, Philipines(Collected from : CSMonitor ) Devastating storms, severe flood, acute famine conditions, etc. hydrological events of extreme nature has changed human history. Any event which is not normal is known as an abnormal event. In the case of hydrology, an event that has a return period of more than 100 years is considered Extreme. According to Herring(2020) of Climate.gov, "An extreme event is a time and place in which weather, climate, or environmental conditions—such as temperature, precipitation, drought, or flooding—rank above a threshold value near the upper or lower ends of the range of historical measurements." Though the threshold is not objective, few researchers have defined "extreme events as those that occur in the highest or lowest 5% or 10% of historical measurements". Some have described events by their deviation from the mean, or by their occurrence interval. Here the most severe five extreme hydrologic events were discussed which ...

Hydroinformatics for Groundwater Management

Hydroinfromatics can be used to manage groundwater also. Significant advancements in water research, as well as new observational and computational capabilities and infrastructures (e.g., MOSES, TERENO, VISLAB, JUWELS), present an opportunity to develop the next generation of smart, data- and model-driven water monitoring systems. Software tools are intended to aid scientists worldwide in the analysis of larger and more complex systems, as well as in the exploration of hydrological extreme scenarios and their consequences. Hydroinformatics is an interdisciplinary field that employs simulations, data science, and decision-making systems to create novel approaches to effectively, sustainably, and equitably manage water in a variety of scenarios. Groundwater resource management in water supply areas is now an essential task in order to minimize anthropogenic interference and ensure the long-term use of available water. Below five articles shows the way hydro informatics was used in the op...
