The Upper Mississippi River System is experiencing more water, more of the time. In some locations, sediment is moving to backwater lakes and reducing vital habitat for overwintering fish. In other locations, sediment is being deposited on riverbanks, which increases habitat for willow, cottonwood, and some shorebirds. Long-term monitoring of sediment dynamics in the Upper Mississippi River System allows resource managers to address the most vital restoration projects for the health of the river ecosystem. Current St. Paul District projects include: McGregor Lake, Big Lake, Robinson Lake, Reno Bottoms and Lower Pool 10 Habitat Rehabilitation and Enhancement Projects, which are in different phases of planning, design, and construction. McGregor Lake is currently under construction. More: https://ow.ly/2c0j50PC5Us #UMRR #BuildingStrong #USACEMVD 📷 Confluence of the St. Croix River and the Mississippi River

Interesting case study on how metal roofs will last in harsh environments! Metal roofs are long lasting!

https://lnkd.in/exWaivrE A warning to any Land Surveyor preparing an ALTA/NSPS Land Title Survey: not all encroachments are so easy to uncover. Were it not for "weird noises at night" this secret tunnel might have escaped the best of due diligence. #ALTA #SubsurfaceUtilityMapping

This is a prime example highlighting the critical significance of precise structural design and the potential risks associated with underestimating soil loads.

Sometimes, it is great to walk down memory lane! We have a binder full of old newspaper clippings of really amazing past projects like this. #MasonryRestoration #StructuralRepair #HistoricRenovation #ConcreteRestoration #TerraCottaRestoration #BuildingMaintenance #BuildingFacade

One of the biggest reasons for higher building and construction standards is to avoid problems such as this. I can imagine so many possibilities that could have caused this, ranging from insufficient strength in the concrete, to improper backfill being performed which could have caused damage to the wall, to simple weather related damage. Understanding these higher quality regulatory practices and utilizing them will ensure that catastrophic damage like this does not happen.

“A cord is 4 feet by 4 feet by 8 feet and represents about 20 trees. So every year, families needed to chop about 100 trees worth of wood just for heating and cooking.” Imagine the work that went into that! 😯🪵 Read the rest of this interesting article, Pitch and Timber: A History of Human Relationships with Trees in Alberta, here: https://lnkd.in/dT4S6Svv #FCC2024 #ForestCapitalOfCanada

Risk and reputation models have a huge impact in building resilience and saving human lives. That’s why at Reppo Labs we are focused on building a decentralized network to crowdsource such models for various use cases and domains. 

🇮🇳 This is the second big landslide event in Kerela in the last four years. Can something be done to build resilience to landslides? The answer is "yes." Here are the steps: 1. Risk maps of the most vulnerable areas to landslides are already available here. This map shows Kerela as a highly susceptible state-- https://lnkd.in/gKxPJAif 2. Based on these maps, new land zoning maps could be prepared where new construction should not be allowed, including avoiding construction on steep slopes. 3. To protect existing buildings and houses, install more plant/tree cover on slopes and build deflection walls to direct debris away from the villages. 4. Have an early warning system in place- extreme precipitation-based triggers could be used as an early warning system in highly vulnerable areas. MoEF&CC Dalberg Jagjeet Sareen Shreya Jai
