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 New Ideas for Opening Start Ups in Water Conservation

PPT Link / Video Link Photo by Naja Bertolt Jensen on Unsplash "Water is a key element for the process industry and a core component for recycling and sustainable management. In industry, water fulfills many functions, including its use as raw material, as a means of transport as well as its use for cleaning and cooling"( source ) "The global Smart Water Management market size is expected to grow USD 13.8 billion in 2021 to USD 22.4 billion by 2026, at a Compound Annual Growth Rate (CAGR) of 10.1% during the forecast period"( source ). Intelligent water conservation and management techniques need to be adopted by the industry such that water can be optimally utilized. Now as per the forecast and recent occurrence of extreme events the necessity of such management has become more significant. Based on this need, some start-up businesses can be established which can help to achieve the water conservation goals. Five such ideas are discussed below. 1)Climate Risk Ass...
