Shields Elementary School Fourth Grade Class and Geographic Information Systems (GIS)(2004) Nicole MinniThe fourth-grade students from Richard A. Shields Elementary School, led by Ms. Cunningham and Ms. Friends, participated in an exciting field exploration of the Lewes and Cape Henlopen area using GPS technology. Accompanied by parent volunteers and Ms. Roe, the class visited historical landmarks and explored Cape Henlopen State Park to locate where the Beacon Lighthouse fell in 1926. Despite the cold, windy weather, the students engaged in learning about maps, examining a USGS Quad sheet and an aerial photo of the region. They studied the differences in map data and discussed changes to the area over time, particularly focusing on natural events and human activities, such as beach erosion and canal dredging. The students also delved into Geographic Information Systems (GIS) using ArcExplorer to analyze various data layers, including historical locations, roads, shoreline data, and hydrology. They explored the DataMIL system and Delaware's GIS framework layers to understand how technology can help measure and analyze geographic changes. By creating hand-drawn data layers, the students observed how the landscape had evolved from 1918 to 2002, noting significant changes like the widening of Canary Creek and the expansion of the Cape. The students were then introduced to more advanced GIS tools like ArcView to create their own data, further developing their understanding of geographic analysis and the dynamic nature of the local environment.Item Strategic Plan for Water Resources Agency(2012) Water Resources AgencyThe mission of the Water Resources Agency, a program within the University of Delaware’s Institute for Public Administration, is to provide water-science and -policy assistance to governments in Delaware and the Delaware Valley through the University’s land-grant public service, education, and research role Goal: Be one of the finest university water resources institutes in America through contributions in public engagement, academia, and research.Item Water Resources Agency Annual Board Mtg.

From Katrina to massive flooding in the Midwest, from record drought in the Southeast (with Atlanta being literally days from running dry), to rampant wildfires in southern California, waterrelated issues are increasingly recognized as of central concern to the economy, the environment, and public safety. Locally and regionally, water issues also loom large. For instance, Delaware Governor Minner recently declared a drought watch for the state (WRA was on the panel that made this recommendation). Issues such as the protection of riparian buffers, water treatment, concerns over water supply and surface water contamination, as well as regional disputes regarding flow in the Delaware River Basin have all become hot topics lately. At the municipal level, the Students Megan, Sallyann, and Shelley, and staffers B.J. and Troy pause for a picture after volunteering for the Christina Basin clean up. Through our project work, collaborations, research, and involvement in advisory panels, WRA seeks to address many of these pressing issues. We have produced the new round of Water Resource Protection Maps to help guide protections in New Castle County, drafted the Pollution Control Strategy for the Christina Basin in collaboration with a multi-agency, multi-state task force, finalized a draft of the State of the Delaware River Basin Report (the scope of which extends into upstate New York and includes drinking water supplies for millions of people), worked with localities to draft source water–protection ordinances, and even helped map the catch basins around campus. Big or small, broad or narrow, these and other efforts by WRA all seek to protect the resource we all use daily, but which sometimes does not get the attention it deserves.Item Water Matters Issue 2(2006-02) Water Resources AgencyWelcome to the second edition of Water Matters! While many of you are familiar with our main facility in Newark, you may not be as familiar with our Lewes office, housed in the College of Marine Studies’ Pollution Ecology Lab, just past the Canary Creek Bridge overlooking the scenic Roosevelt Inlet. It may seem like a sleepy backwater locale, but in fact we’ve had a good deal of excitement here since the last edition of our newsletter. Besides the normal clatter the seagulls make while breaking open clam shells on the rooftop, we were pleasantly distracted by visitors from Hollywood, who were filming the movie “Failure to Launch” at the Marine Operations Building next door. Although their visit was short like the Kalmar Nyckel that was docked during the Annual Coast Day event and our annual visit by the green tree frog, the adventure never ends. A deep-sea dolphin was recently biopsied in the Marine Education, Research & Rehabilitation Institute building, just behind us, to determine its cause of death, and brant (goose-like birds) flocked their way to the grasses in front of Cannon Lab. Finally, we have the pleasure of sharing office space with a team of archaeologists, who are examining and cataloging items from what is believed to be a sunken 1760s-era cargo ship just offshore. They have collected pottery, glass, and many other items from the ship during a dredging operation to replenish Lewes Beach.Item Water Matter Issue 1(2005-08) Water Resources AgencyIn Delaware water has always been in the news. Most of our state is on an island. Our towns were founded beside the water. Our state and the river share the same name. Over the past decade, we’ve had three droughts and three 100-year floods. At the coast, on the farm, and in our back yard, clean and plentiful water supplies are necessary to sustain our economy and the environment. At the Water Resources Agency (IPA-WRA), water has always been our first name. Our work supporting the public service, education, and research land-grant mission of the University of Delaware is funded by you—the public—and the governments that you elect. On campus we provide assistance to governments in Delaware and the Delaware Valley based on sound science and public policy ideals. Today, in the first of a series of newsletters, we’d like to introduce our staff and students to you. They have experience in many areas—planning, GIS, natural resources, policy, and engineering. So stop by to see us in Newark or Lewes. Or just call us...IPA-WRA.Item Instructions and Tables for Computing Potential Evapotranspiration and the Water Balance(1957) C.W. Thornthwaite; J.R. MatherThe term water balance has recently gained widespread popularity among climatologists, geographers, geologists, hydrologists, and others concerned with water problems. It has, of course, taken on a variety of meanings depending on the user. In this publication, the term water balance refers to the balance between the income of water from precipitation and the outflow of water by evapotranspiration. It is a climatic balance since the quantities of precipitation and evapotranspiration are active factors of climate. From a comparison of the seasonal march of precipitation with the evapotranspiration, the magnitude of other related moisture parameters, the water surplus, water deficit, soil moisture storage, and water runoff may be determined. The climatic water balance was introduced into the literature by Thornthwaite in 1944 (Trans. A.G.U., Vol. 26, Part V, pp. 683-693) and used by him as the basis for a new and improved classification of climates in 1948 (Geogr. Rev., Vol. 38, No. 1, pp. 55-94). Since that time, further studies of the water balance by the staff of the Laboratory of Climatology have led to revisions and extensions of the balance itself and its applications. These have been summed up in a publication by Thornthwaite and Mather in 1955 ("The Water Balance," Publications in Climatology, Laboratory of Climatology, Vol. VIII, No. 1, 104 pp.). The approach has been utilized in the following detailed studies of water problems which have appeared in previous issues of Publications in Climatology of the Laboratory of Climatology: D. B. Carter, "The Water Balance of the Lake Maracaibo Basin During 1946-53," Vol. VIII, No. 3, pp. 205-227. T. E. A. van Hylckama, "The Water Balance of the Earth," Vol. IX, No. 2, pp. 53-117. D. B. Carter, "The Water Balance of the Mediterranean and Black Seas," Vol. IX, No. 3, pp. 119-174. In developing the methods of analysis of the water balance which are used in the Laboratory of Climatology, it has been necessary to produce a number of tables to facilitate the performance of the various computations. Since these methods are being employed widely throughout the world, the present volume has been prepared to give detailed instructions and to provide the necessary tables.Item Report of the Delaware Report of the Delaware Water Supply Coordinating Council Water Supply Coordinating Council 2005(2005-09-26) Water Resources AgencyThis is the presentation version of the Report of the Delaware Report of the Delaware Water Supply Coordinating Council Water Supply Coordinating Council in 2005.

Due to surplus precipitation, water conditions in the streams and aquifers are in the normal range and are significantly better at this time than during the corresponding period one year ago. The Artesian Water Company is working on plans to drill new wells and employ aquifer storage and recovery technology in the coastal plain aquifers north of the C&D Canal. The City of Newark is continuing with plans to build a new reservoir, to build a new water treatment plant at its south wellfield, and to utilize Hoopes Reservoir releases this summer, if necessary, to improve the reliability of its White Clay Creek intake. The City of Wilmington has a reliable water supply and is self sufficient to meet peak demands in its system under current regulatory conditions. The City is moving forward to conduct a dam safety inspection of Hoopes Reservoir. The City has also developed a draft Water Supply Operating Plan to access storage in its Hoopes Reservoir. United Water Delaware is working to secure additional interconnections from other water purveyors, evaluate new reservoir options near its Stanton facilities, and implement a chloride monitoring plan which will prevent elevated salt levels in drinking water during drought. Several of these water supply options have been implemented and are now available to meet peak demands should an extended dry period occur this summer. Of statewide significance, Senate Bill 370 was introduced on May 18, 2000 which would transfer the authority for awarding water supply service areas from the Delaware Department of Natural Resources and Environmental Control (DNREC) to the Public Service Commission (PSC).Item Synthesis of Water Rates in Delaware and Contiguous States(2004-07) Gerald J. Kauffman; Marlyse WilliamsThe University of Delaware, Institute for Public Administration, Water Resources Agency (UDWRA) conducted an inventory of water rates for public- and investor-owned water utilities within Delaware and the surrounding states of Maryland, New Jersey, and Pennsylvania. The purpose of this inventory is to summarize and compare residential water rates for Delaware and surrounding states. The authors intend this report to be useful to water providers, Federal, State, and local water agencies and the public. This report is an update of the original water rate inventory prepared in September 1996 and a later report: Economic Synthesis of Water Rates in Delaware and Surrounding River Basins, August 21, 2000.
