Name: TA: Lab 3- Surface Water GEOL 1122 Before answering the questions for each section, make sure you have watched the video(s). After you have completed this worksheet, save it and upload it to the assignment folder for Lab 3 in iCollege. Please use your own words to answer the questions, and include as much detail as possible . Lab Objectives At the end of this lab, students should be able to:  Understand “where is water found and how much is there?” on a global scale  Name and explain major reservoirs and fluxes in the hydrologic cycle  Know the distinguishing features of wetlands and ponds/lakes  Understand how river velocity and sediment transportation capacity changes along a river network and why this changes.  Understand the importance of urban stormwater infrastructure and how it relates to social and environmental justice or the lack thereof Part 1: Introduction To answer these questions, first watch the “Lab 3, Part 1: Introduction” video on iCollege. Please answer the questions in your own words. 1) Hypothesize a process by which water from the ocean moves to the land surface. Please give a detailed answer with your reasoning fully explained. (4 pts) On a really hot day water from the ocean evaporates in the air, goes through the process of condensation,goes into the atmosphere and eventually goes through the precipitation process. The precipitation process for example can be rain. The rain falls and lands on a land surface. 2) Pick three of the fluxes listed on the right side of this slide. For each of the three fluxes you pick, please search the internet to explain the process, in addition to naming the two reservoirs involved. In other words, your answer needs to include the starting and ending reservoirs for this process . (4 pts) Infiltration ; starting reservoir atmosphere - ending reservoir ocean . Evaporation ; Lakes starting reservoir ending reservoir atmosphere . Precipitation ; starting reservoir is atmosphere and ending reservoir is ocean . The given answers in the answer attached section in the attachment is confirmed to meet the required standards .

3) Use the internet to find a lake or wetland in the state of Georgia. Please write a thoughtful, well-developed paragraph (of at least five sentences) describing this lake or wetland. Important things to include are: (1) How and when did this feature form? (2) What organisms use this feature as a habitat? (3) what social, historical, or economic functions does this feature serve? (6 pts) Lake Lanier is a reservoir located in Georgia's northern region. It was built in 1956 when the Chattahoochee River's Buford Dam was completed, and it is also fed by the Chestatee River. The lake, which was established in 1956, acts as a water storage and flood control reservoir. To flood the 38,000 acres slated to become Lake Lanier, the government had to evict nearly 250 households, over a dozen businesses, and more than 20 cemeteries. During the summer, the lake is home to green-backed herons, Canada geese, kingfishers, ospreys, and great blue herons. Squirrels, wild turkeys, rabbits, and white-tailed deer can all be found in the woodland that surrounds the lake. The lake serves a variety of tasks, including hydroelectricity, navigation, flood mitigation, wildlife conservation, and water supply; however, most locals rave about the fishing, boating, and parks that make up the 38,000 acres of the Lake. 4) Please answer whether or not you think you live within a watershed (please explain your reasoning ). (2 pts) The town where I live is in Pacific, Missouri where the Meramec River flows. Since this river empties into the Mississippi River at Arnold, Missouri, the Meramec River watershed is also part of the Mississippi River watershed which itself is a part of the basin that drains into the Gulf of Mexico along with the Rio Grande. 5) Please hypothesize whether or not it is possible for a piece of land to be part of more than one watershed simultaneously (fully explain your reasoning). (4 pts) It is not possible for a piece of land to be part of more than one watershed. This is because I think the land can only drain towards one reservoir. I believe some watersheds can combine as the water drains to one area, like a stream, so more than one watershed can go towards a reservoir, but a piece of land can only be part of one watershed. Also ,Climate has a significant impact on watershed forest ecosystems, streamflow intensity and scheduling, water levels, and a variety of other important watersheds. Part 2: Why Do Rivers Curve? Watch the linked YouTube video “Why do Rivers Curve” in its entirety to answer these questions in your own words .

6) According to the video, how are mountain streams different from rivers and streams that run through plains? (4 pts) Mountain streams are different than those that run through plains because mountain streams fall down steep mountain sides and the area is a lot rockier . It would be harder for the mountain streams to move freely as they are rapidly falling down . Rivers in plains move less rapidly and have softer soil that they can easily carve out and move freely into whatever course 7) Explain the process by which streams/rivers running through flat areas begin to curve. Please use as much detail as possible, and make sure to include the role that water velocity plays (i.e., make sure to describe how water velocity is different in different parts of the stream/river). (4 pts) The rivers in flat areas begin to curve when there is a disturbance on the side banks of the rivers. The river will then start taking away the dirt and sediments there and it will take more and more as time goes by. Overtime, the flow of the river will be diverted onto one side and curve as the other side of that bank water will flow slower. Because it is not moving as fast, the sediment on that side will slowly fill up with sediments and builds up until it becomes new land on that bank. The water will then flow down and its high velocity will hit the other side of the banks, where the other bank water flow will be slower. The slower side will also have more soil deposition since the velocity is slower and overtime create new land again. The water on the other side of the bank will hit the banks repeated due to is fast velocity and overtime carve into the banks 8) What is the relationship between the width of a stream/river and the distance between consecutive meanders? If the width of a stream is 3 meters, what is the expected length of one S-shaped meander in this stream (explain how this was calculated)? (4 pts) The bigger the width of a river, the longer it will take to meander. The length of one S shape meander is 6 times the width of the channel. So if the width is 3 meters, the S shape meander will be 18 meters. 9) Explain the formation of an oxbow lake in as much detail as possible. (4 pts) Oxbow lakes form as the river continues to meander and curve it will eventually meet itself. Once it meets itself, the river will then follow a straighter path downhill and will not have that "slingshot" velocity of it bumping and taking sediments away from the banks. The super curved area will slowly close off from the river and form a lake since it is no longer connected to the river. The river will then continue on its course
