Water Resources International Development: What On Earth Are We Doing?, Patrick Ray

All ECSTATIC Materials

Large agencies such as the World Bank, the Millennium Challenge Corporation, the United Nations, regional development banks (such as the Asian Development Bank), and philanthropic organizations (such as the Rockefeller Foundation) are actively engaged in water resources development in low-income countries. Why? And what metrics do they use to decide if the investments of hundreds of millions or billions of dollars in water infrastructure projects are justified? And what accommodations do they tend to make for risks such as climate change? And what attention do they tend to give to questions of equity? I probably have no idea. But I’ve …

Dynamic Adaptive Policy Pathways, Marjolijn Haasnoot

All ECSTATIC Materials

• Dynamic Adaptive Policy Pathways (DAPP) is a decision making approach that explicitly includes decision making over time. The essence is proactive and dynamic planning in response to how the future actually unfolds.
• DAPP explores alternative sequences of decisions (adaptation pathways) for multiple futures and illuminates the path dependency of alternative strategies. It opens the decision space and helps to overcome policy paralysis due to deep uncertainty. There are different routes that can achieve the objectives under changing conditions (like ‘different roads leading to Rome’).
• Policy actions have an uncertain design life and might fail sooner or later to continue achieving …

Adaptive Water Infrastructure Planning For A Changing World, Sarah Fletcher

All ECSTATIC Materials

Water planners face the challenge of ensuring reliable water supply for people and the environment. Long-term changes and short-term variability in both the natural and social environments create large uncertainty in future water supply and demand. This makes it difficult to know when and how to adapt water systems through operational changes, policy, and infrastructure development. Adaptive planning approaches, in which planners defer action and respond as the system changes over time, have the potential to enable robustness to an uncertain future without unnecessary infrastructure development or policy changes. However, adaptive approaches may prevent planners from leveraging economies of scale, …

Adaptive Policy Design In Water Resources Systems Under Uncertain Climate And Human Stressors, Jon Herman

All ECSTATIC Materials

Long-term planning of water resources systems must contend with severe uncertainty in future projections of hydroclimatic variability across multiple scales, as well as uncertainty in human behavior, such as land use and reservoir operation. This talk will review recent developments in adaptive policy design to meet this challenge, centered around the key question: how should we learn from, and react to, dynamic observations of hydroclimatic, human, and ecological variables to ensure long-term sustainability? Specific contributions will cover three areas: (1) adaptation of short-term control rules, enabling existing infrastructure to manage multiple objectives across a range of possible futures; (2) exploration …

Strategies For Managing The Colorado River In An Uncertain Future, Jian Wang

All ECSTATIC Materials

Colorado River managers face a deeply uncertain future. Projections of declining watershed runoff are likely to necessitate restructuring of the present interpretation of the Law of the River that allocates water supply among Mexico and the seven states of the Basin. Additionally, the magnitude and distribution of consumptive uses of water will change. Outcomes for river and reservoir ecosystems are poorly predicted. How should we make better decisions given these uncertain factors? To help answer this question and expand conversation about the Colorado River management issues, we (1) classify different levels of uncertainty to guide decisions about which modeling tools …

Developing Open Source Software Using Version Control Systems: An Introduction To The Git Language For Documenting Your Computational Research, Jared D. Smith, Jonathan D. Herman

All ECSTATIC Materials

Version control systems track the history of code as it is committed (saved) by any number of developers. Have you made a coding error and cannot debug it? Version control systems allow for resetting code back to when it worked, and show what code has changed since previous commits.

The contents of this lecture provide an introduction to the git version control language, GitHub for cloud hosting open source code repositories, and tutorials that demonstrate common and useful git and GitHub practices. This lecture is intended to be coupled with a discussion on creating reproducible computational research.

Milwaukee Wet Weather Flow Management System Planning, David Watkins

All ECSTATIC Materials

Many older cities across the United States rely on combined sewers to convey both stormwater runoff and sanitary sewage. Combined sewer overflows (CSOs), containing untreated sewage, occur during extreme wet weather, when the capacity of these combined sewer systems is exceeded. Across the U.S., CSOs pose a serious threat to water quality in thousands of lake, river, and coastal ecosystems. In addition to harming the natural environment, they may be a threat to human health and have adverse economic consequences (e.g., beach closings, reduced aesthetics, tourism impacts).

In this assignment, students role-play engineering consultants tasked with developing a cost-effective plan …
