Objectives and Outcomes
This course is intended to provide students with an understanding of water, land-water interactions, and aquatic ecosystems that will
inform their professional approaches to landscape architecture, urban and regional planning, and architecture, and contribute to protecting, improving, restoring, and sustaining water resources.
Topics Covered
This course looks at water across the globe in relation to (1) aquatic ecology, (2) land-water interactions, emphasizing hydrology and water quality, and (3) human activities, including design questions. Each of these three aspects is covered in all parts of the course, although the emphasis shifts among them.
The course is organized broadly into four parts. Topics are covered from local to continental scales and are illustrated with examples and case studies from around the world.
Part 1: Background information and a broad overview of the subject, including the importance and values of water, physical and chemical characteristics, ecological concepts, ecosystem services, human impacts, and design approaches to sustainable water- resources management and the maintenance of healthy aquatic ecosystems. Part 2: Aquatic ecosystems (flowing waters, lakes and ponds, temporary waters, shorelines and riparian areas, inland and coastal wetlands, and nearshore coastal waters); their plant and animal communities; their connections with each other; their relationships with the terrestrial landscape and land uses, including the built environment and natural areas; and design considerations for aquatic habitat protection, restoration, and creation. Part 3: Land-Water Interactions: Watersheds; precipitation; land use and the hydrologic cycle; groundwater-surface water interactions; water withdrawals; surface hydrology, hydraulics, and geomorphology; hydrologic calculations for estimating runoff and groundwater flow; water quality issues; and design approaches to managing infiltration and runoff. Part 4: Special topics: Student project presentations.
Course Format
This is primarily a lecture course, but class time will also be spent in discussions of readings, practical hands-on exercises in hydrological analysis and site evaluation, and student presentations. A weekend field trip in early spring will compare urbanized and less heavily impacted aquatic habitats.

2 Readings
For each lecture topic, required background readings are listed, along with optional supplemental readings that will provide additional background information. Required readings are in Dunne and Leopold, a variety of texts that are on reserve in the Loeb Library, and in articles and other materials that are available online. The List of Resources for GSD 6333 provides a comprehensive list of the reserve texts, additional books that may be of interest, and a wide variety of articles, manuals, and other resources. These are resources that should be of use to you not only for this class, but after you have left the GSD and are working in the field. Many of them are available online, and website addresses are listed for these. Listed journal articles are generally available online through the Harvard library system.
The Resources List also includes background information on journals, manuals, and websites that can serve as valuable resources for current and future work you may undertake involving water resources.
Textbook
There is no required textbook for this course, but we STRONGLY RECOMMEND that you get a copy of Dunne and Leopold, Water in Environmental Planning. Published in 1978, this book remains the best available overall text presenting an overview of hydrology and water concepts as related to planning and design. It can be found new for just over $100, but used copies in good condition are available for $30-50. Readings in this book serve as background to many of the lectures in this course.
Evaluation
Students will be evaluated on attendance (25 points), performance on three short (2-page) written assignments and 3 quizzes (10 points each), and an oral presentation (15 points) and final paper (30 points) on a research topic or design problem of interest to the student. Short assignments or quizzes will be due, on average, every two weeks. Content and presentation, including spelling and grammar, count. (See pp. 17-20 for more information.)

Course Readings
For each major class topic, the syllabus lists a number of pertinent background readings. Those listed as Background Readings are intended to provide basic background to the lectures. All listed books and articles have been placed on reserve in the library, with the exception of some manuals and resources which are available online.
Some classes will include a discussion of a research paper, review, or case study pertinent to the current topic. Please read Discussion Readings before the class and be prepared with thoughts, questions, and insights to share with the rest of us. Discussions will generally be planned to take up about ½ hour of class time. Class participation will count for 15 points.
I have listed some Optional Supplemental Readings which provide additional information that you may find of interest if you would like to learn more about a particular topic. These sources are also on reserve in the library or available online.
In many cases, the background materials duplicate one another. I have indicated when you can select which source (s) to read. You should familiarize yourself with the major texts and determine which ones are best for you in terms of the way they are written, their approach, and their level of detail.
Some of the reference sources are highly technical, while others are more general in scope. It is up to you to determine the level of detail that will be useful to you. Many of the assigned background readings will contain some materials that you will probably want to skim, to obtain a general understanding rather than develop a detailed technical expertise. I do not expect you to obtain an engineer’s or scientist’s knowledge of the details of climatological analyses, hydrogeological measurements, engineering formulas and calculations, taxonomy of aquatic 16 biota, bioassessment methodologies, and other topics we will cover. You should become sufficiently familiar with basic concepts associated with all of these topics to be able (1) to explain them clearly and succinctly, and (2) to incorporate them into your thinking about specific land-use problems and design questions.
There are also many other books in the Harvard library system, as well as extensive resources available on-line, providing different perspectives and much more detailed information on the topics we are surveying as well as on other aspects of aquatic ecology, water resources management, hydrological analysis, and water-focused design issues.
A bibliography listing all recommended and optional reference texts and papers, additional references, as well as technical manuals and websites of potential interest, is provided separately in a document titled “Resources for GSD 6333,” posted on the course icommons website.

There are no labs associated with this course, but we will spend a lecture period in carrying out some basic hydrologic analyses. Materials for these exercises will be provided as handouts in advance of class.
Short Assignments
You will be expected to submit three short (two-page) written exercises for this course. One involves summarizing major topics of research in aquatic ecology; the second provides a report on a visit to the New England Aquarium and a specific organism, group of organisms, or ecosystem; and the third involves broadly delineating a watershed and identifying both source areas and ultimate receiving waters.
The short exercises will be graded on content and presentation. Treat each of them as if it were a response to a client’s request for information. Grammar and spelling count. Each exercise will be worth 10 points.
Short Exercise #1. Overview of key research topics in aquatic ecology. (Due January 31) From the list of professional Journals in Aquatic Ecology provided in the List of Resources for GSD 6333 (on the course icommons site), select two journals, and examine all of the articles in one-to-three recent issues (within the past five years) of each. (I recommend that you steer clear of special issues focusing on a single major topic.) You should read enough of each article to have a sense of the background justifying the research, the questions being asked, the results, and their broader implications – i.e., you will probably need to look at more than the title alone. Skimming the abstract may be sufficient, although you may find it useful – and interesting – in some cases to look at the introduction, and possibly the discussion, as well. The idea is to get a general sense of major research topics in aquatic ecology, rather than to conduct a detailed evaluation of each individual research study.
17 In the written summary, you should identify the two journals, and the issues of each that you reviewed, and provide a succinct overview of the contents, as follows.
Your summary should not exceed two (2) pages. 1. Classify the papers into groups, each based on an overarching common theme or topic that you think is useful for the classification. Make a list of these major topics, and identify the number of papers in each group from Journal 1 and Journal 2. How would you characterize each journal in terms of its content? Are the papers in both journals similar in terms of the major questions and concepts, or do they differ? 2. For each thematic group of papers, discuss the major concepts and questions driving the research. How do these concepts and questions contribute to your understanding of aquatic ecology and land-water interactions? What application do they have to design and planning? Are certain topics more pertinent than others? 3. Do the research findings of any of the papers give you ideas or suggest things that should be considered by landscape architects, architects, and planners? 4. Do you have any thoughts of how to improve communication between aquatic ecologists and architecture/design professionals?
Short Exercise #2. Visit to the NE Aquarium (Due February 10.)
Visit the New England Aquarium and explore the exhibits. Spend some time looking at exhibits on freshwater habitats and their life, and exhibits on coastal wetlands and nearshore waters. For the written exercise, choose an organism or group of organisms, or a habitat or aquatic ecosystem of particular interest and describe ecological aspects, conservation issues associated with human activities, and any thoughts you have about potential design opportunities in relation to the study organism or ecosystem. This exercise will be due on February 10.
Short Exercise #3. Watershed delineation (by hand) (Due March 24)
Choose your place of birth, a childhood home, your current residence, or the Harvard Forest’s Fisher Museum in Petersham, MA, and determine the following things about the watershed. You will need a topographic map of the local area, or another map that shows the surrounding area with topographic details including surface-water bodies. You will probably also need a larger map showing major rivers that flow to the ocean.
1. Identify the location, and show it on the map. 2. When water flows off the roof in rainstorms, what is the first water body to receive the surface flow? What path (approximately) does the roof water follow to get there? (If the building is in an area with a subsurface stormwater conveyance network, can you tell where the storm drains take the water? Where would the water flow if there were no storm drains?) 3. On the map, outline the watershed of the water body identified in step 2, up to the point where the water from the roof enters (i.e., where did the water in the water body originate?) 18 NOTE: If the initial receiving water is a large, mainstem river, it will probably not be practicable for you to delineate the entire watershed. In this case, follow the river upstream until you reach the upper end of one headwater tributary. 4. Where does water leaving the property ultimately discharge into the ocean (or a closed inland basin)? What is the path that it takes from the building to the final receiving water? Quizzes
There will be three short quizzes, designed to show you and us how well you understand major concepts, terms, and relationships discussed in the lectures and readings in the preceding weeks. The quizzes will be posted on the course website and will be due 4-10 days later, on February 21, March 25, and April 14. Each quiz will have 5-10 short-answer questions and will count 10 points. The quizzes will be take-home, to allow those with difficulty writing in English adequate time to compose answers to the questions. You will be asked to sign a statement that you have not consulted the internet or other sources while completing the exam.
Research Project/Paper
Each student will carry out a detailed investigation of a topic in aquatic ecology/land-water interactions that they find of interest. Each project should include aspects of aquatic ecology, land-water interactions, and design. A one-paragraph summary of the proposed topic is due March 10. The results of the investigation will be presented to the class in a 10-minute talk during the last two weeks of the term, and a final paper will be due not later than May 6. An abstract summarizing the project content should be provided with your talk and final paper.
Students are encouraged to turn in the paper earlier than the final deadline if possible, to allow me time to read the paper carefully and provide useful comments and feedback, as well as a thorough assessment for evaluation purposes.
Topics may fall into any of the following broad areas:
1. Aquatic Ecology – explore a concept (such as bioassessment of water quality, river continuum concept, land-water subsidies, others); a specific habitat or habitat type (e.g., large-river floodplains, mangrove wetlands, Cambodia’s Tonle Sap lake, others); or an aquatic organism or group of organisms.
2. Design – redo a design problem you have worked on in the past, with new attention to implications for aquatic ecosystems and aquatic life, and to ways to reduce impacts. Current Studio projects are not eligible. Consider the watershed, aquatic resources, hydrology, water quality, habitat issues, design and BMPs, including problems with the initial design and specific solutions. NOTE: For students re-designing studio projects, the final paper should include a copy of the original studio report, which will provide the background information. Your paper for this course should not duplicate the earlier work, but should rather present a brief overview of the problems to be addressed, issues with the original design, basis for making revisions, and the new solution(s).
19 3. Water and Planning – choose one of the case studies in Dunne and Leopold Chapter 1, bring the data up to date, and add the ecological context. Alternatively, choose a specific problem that relates to planning, research the problem, and discuss.
4. Other – research a problem in aquatic ecology, society, and water-sensitive design that you find of interest.
Field Trip (April 9 and 10)
A field trip to Central Massachusetts is scheduled for Saturday, April 9 and Sunday, April 10. The main theme is ecological assessment of habitat quality and aquatic community integrity in urban and relatively undisturbed aquatic habitats. In the course of the trip, we will visit and sample aquatic life and habitat characteristics in relatively undisturbed vernal pools in a forested park in the city of Leominster. We will then compare our findings with those from some created vernal pools in the city of Worcester. We will also compare a recently day-lighted urban stream with a forest stream of similar size, to evaluate some of the common biological and habitat metrics used to evaluate water quality and impact of land uses. Activities will include habitat assessment, biological sampling, calculation of ecological monitoring metrics, and graphing of results. In addition to these comparisons, we will visit two forested wetlands and will examine soil cores in and adjacent to the wetlands to determine the boundary of the wetland (i.e., where soils are reduced vs. oxidized). We will stay overnight at the Harvard Forest in Petersham.
