With the rise in severe storms driven by climate change, urban flooding is the costly result.<\/p>\n<p><a href=\"https:\/\/www.beaverinstitute.org\/wp-content\/uploads\/2021\/03\/Beaver-Hydrology-impact-in-Milwaukee-final-1.pdf\" rel=\"noopener noreferrer\" target=\"_blank\">A new study<\/a> by two UWM researchers shows that restoration of an animal that Wisconsin was known for 300 years ago \u2013 beavers \u2013 could be a part of the solution.<\/p>\n<p>Enough of the dam-building animals living in the right spots along creeks and streams can alleviate flooding in some of Milwaukee County\u2019s worst-struck areas, according to research by Qian Liao, an associate professor of civil engineering, and Changshan Wu, a professor of geography.<\/p>\n<p>When beavers build homes, called lodges, in wetland habitats, they also construct dams to create a pond so that they can enter the lodge from under water. A significant amount of water backs up as the pond forms, and that hinders fast-moving water, which has a cumulative effect downstream.<\/p>\n<figure id=\"attachment_91745\" aria-describedby=\"caption-attachment-91745\" style=\"width: 300px\" class=\"wp-caption alignleft\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-91745\" src=\"https:\/\/uwm.edu\/news\/wp-content\/uploads\/sites\/41\/2021\/04\/beaverAdobeStock_261867103-300x200-1.jpg\" alt=\"\" width=\"300\" height=\"200\" \/><figcaption id=\"caption-attachment-91745\" class=\"wp-caption-text\">The dams that beavers build in rivers and streams help slow the water rushing downstream. (Stock photo)<\/figcaption><\/figure>\n<p>\u201cIf there are hundreds of beaver dams distributed across the entire watershed, you have many locations where you can reduce the water flow,\u201d Liao said. \u201cAnd not just the volume, but also the timing, so that the combined delay at each dam has a significant impact on the downstream peak flow.\u201d<\/p>\n<p>Bob Boucher, founder of the environmental advocacy organization Milwaukee Riverkeeper, proposed the study to officials at the Milwaukee Metropolitan Sewerage District, which funded the research.<\/p>\n<p>The researchers were asked to investigate several questions: How much flooding could dams from a healthy beaver population abate? How many dams would be necessary, and where should they be? Does the watershed have the right habitat to support a beefed-up beaver population?<\/p>\n<h3>Fieldwork provides info<\/h3>\n<p>To begin, Boucher, two undergraduates from Wu\u2019s lab, and Leah Holloway from Milwaukee Riverkeeper conducted fieldwork to determine the beaver population capacity and identify locations where beaver would have the best chance at surviving.<\/p>\n<figure id=\"attachment_91752\" aria-describedby=\"caption-attachment-91752\" style=\"width: 300px\" class=\"wp-caption alignright\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-91752 size-full\" src=\"https:\/\/uwm.edu\/news\/wp-content\/uploads\/sites\/41\/2021\/04\/J.Marshjpg300x200.jpg\" alt=\"\" width=\"300\" height=\"200\" \/><figcaption id=\"caption-attachment-91752\" class=\"wp-caption-text\">Jackson Marsh was one field assessment location ranked as high for its likelihood of supporting beaver restoration. (Photo courtesy of Bob Boucher)<\/figcaption><\/figure>\n<p>Liao and Wu provided the fieldworkers with maps that showed the existing wetland areas throughout the subdivided watershed. The maps were on a geographic information system (GIS) platform that allowed the field workers to record multiple spatial features of each area and then view all added variables at once.<\/p>\n<p>\u201cIt was like having a drone view,\u201d Boucher said.<\/p>\n<p>Collecting data with their cellphones, Boucher, Holloway and students Max Rock and Madeline Flanner spent much of 2020 visiting 163 locations on the GIS maps. They made observations either by canoe or by hiking into areas at bridge road crossings to evaluate whether locations had ample food sources and the kinds of trees the animals use for building.<\/p>\n<p>A cellphone app that Rock developed helped the team rank the locations by quality, based on all the data. What they found was enough habitat to support around 4,500 beavers \u2013 or about one family for each 100 acres of wetlands.<\/p>\n<h3>Modeling rainstorms<\/h3>\n<p>For the next step, Liao and graduate student Syeda Mahmuda Noor\u00a0used the top sites identified from the fieldwork and modeled the effects of dams in those areas during high-water rain events. He built his hydrological model using 10 years of data on rain events and stream flows from National Oceanic and Atmospheric Administration and the U.S. Geological Survey for validation.<\/p>\n<figure id=\"attachment_91753\" aria-describedby=\"caption-attachment-91753\" style=\"width: 300px\" class=\"wp-caption alignleft\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-91753\" src=\"https:\/\/uwm.edu\/news\/wp-content\/uploads\/sites\/41\/2021\/04\/MudLake.2-300x200-1.jpg\" alt=\"\" width=\"300\" height=\"200\" \/><figcaption id=\"caption-attachment-91753\" class=\"wp-caption-text\">Mud Lake in the Cedarburg Bog, near Saukville, was another location where conditions were right to attract beavers, including the presence of water lilies, part of the animal\u2019s diet. (Photo courtesy of Bob Boucher)<\/figcaption><\/figure>\n<p>\u201cWe ran the model and found that individual rain event data would accurately reproduce the past river flow observations recorded at the USGS river stations,\u201d he said. \u201cThen we added the hypothetical dams at the locations deemed to be best and ran the model again.\u201d<\/p>\n<p>Liao fed the model different scenarios of beaver dam activity at 52 locations that would provide the highest potential to reduce downstream flooding, while also having ideal conditions for beaver. According to the model, dams would reduce the peak flow by between 14% to 48%, depending on the details of the storm, but also on the dam location.<\/p>\n<p>\u201cFor example, if the storm was relatively uniform across the entire watershed, then you would have the highest reduction of water flow,\u201d he said. \u201cBut if the storm dropped most of its rain on southern areas of the river watershed, then dams located upstream where there\u2019s less rain will have a diminished effect.\u201d<\/p>\n<h3>Room for 100 dams<\/h3>\n<p>An area of the river that lies just north of West Bend is particularly well-suited, said Boucher, and able to support close to 100 beaver dams.<\/p>\n<p>That\u2019s great news for three areas in Milwaukee County that are designated as flood zones by the Federal Emergency Management Agency \u2013 Thiensville, Brown Deer and Glendale.<\/p>\n<p>\u201cThere have been other studies that showed the effect on flooding of introducing beaver dams, but those studies only measured the effect a few miles downstream,\u201d Liao said. \u201cWhat we did is a little different. We looked at it on the watershed scale.\u201d<\/p>\n<p>The study shows how the idea could be repeated to be one of the tools to address urban flooding across the Great Lakes region, added Boucher.<\/p>\n<p>And benefits would not be limited to the FEMA flood zones, he added. \u201cThousands of road culverts that lie across the area could last twice as long if flooding were reduced. This would add resiliency to the whole system.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Beavers were once abundant in the Milwaukee area, but fur trappers wiped them out more than 200 years ago.
