PPT-ALASKA CERTIFIED EROSION & SEDIMENT

CONTROL LEAD TRAINING AKCESCL INSTRUCTOR Copyright Alaska Stormwater Steering Committee amp Creative Courses January 2022 COURSE OBJECTIVES Assess and manage risks of erosion and sedimentation on construction sites. OR. Control of margin dynamics by sediments, part 4: erosion and transport. Alex Densmore. Department of Geography & Institute of Hazard, Risk and Resilience. Durham University. Sanjeev discussed sedimentary basins as bathtubs that evolve and fill over geological time scales, and (importantly) preserve a record of the detritus from margin evolution. Physical Weathering. Weathering. is the breakdown of rock or soil. . Physical . weathering occurs when natural forces, such as wind, running water, and moving ice, physically break up rock and soil into smaller particles. . The . surface. features of the Earth change as a result of observable physical and chemical processes . Weathering and Erosion. This is a monument . called Cleopatra’s . Needle. It was carved in Egypt around 1450B.C. The sides are carved with hieroglyphs, the writing of ancient Egypt. It stood in the dry, hot Egyptian desert for over 3000 years. During that time, the hieroglyphs remained distinct.. __________, ___________, and __________ act together in a cycle that wears down and builds up Earth’s surface.. ________, ___________, __________, _______, and ________ all cause erosion.. _______ causes mass movement, the process that moves sediment downhill.. J. Quigley. 4/2012. Water Shapes the Land. Water Shapes the Land. The Mississippi River is like a thousand dump trucks… every year it carries more than 300 million tons of sediment to the ocean! . This sediment is being washed away from the surface of the land and is called erosion.. Lesson 1. Water Erosion. How does Moving Water Cause Erosion?. Erosion is the process in which sediment that has been broken down through weathering is moved.. Agents of Erosion are:. Water. Wind. Glacial (ice). J.Q. Wu, S. Dun, W.J. Elliot, H. Rhee. J.R. Frankenberger, D.C. Flanagan . P.W. Conrad, . R.L. McNearny. Introduction. A crucial component of planning surface mining operations as regulated by the National Pollutant Discharge Elimination System (NPDES) is to estimate potential environmental impacts during and after mining operations.

You’ll indulge in mouth-watering, freshly prepared meals at the lodge after you’ve had a long day of fishing. You may be wondering what to do with all of that freshly caught salmon when you arrive back home, or heck, how to cook salmon! Salmon has a quality freezer life of four to eight months, and we’ll freezer pack and vacuum seal your fish for you, so you know it’s perfectly packaged. Let us guide you on a simple way to prep your fish after the Alaska fishing season has come to an end! The creation of sedimentary rocks. Weathering and Mass Movement. Objectives:. 1. Describe the processes by which erosion wears down and carries away rock. 2. Distinguish between chemical and mechanical weathering. The. . Erosion-Deposition. . Process. Constructive vs. Destructive. Constructive process build up features on Earth’s surface. Lave erupting from a volcano hardens and forms new land on the area where lava falls..
