So what is Water Resources Engineering?

Some definitions Planning, design, construction, management, policy development, operations, and/or enforcement that – Alters the hydrologic cycle – Affects fate or transport of pollutants/water quality constituents – Impacts economic, social, political, cultural, environmental, or ecological concerns Move water in space, time, quality, phase, or among uses CEE 6/5460 – Water Resources Engineering David Rosenberg 2

Water Resources Engineering is… – Multi-disciplinary – Must identify and address constraints under which engineering can take place. CEE 6/5460 – Water Resources Engineering David Rosenberg 3

Constraints • Hydrologic – How much water? Where? When? With what frequencies or reliabilities? • Physical – Capacities, sizes, etc. of existing or planned infrastructure • Economic – How will water be used? At what value(s)? Who benefits and who pays? When? • Financial – Budget for construction, operations, etc. ? CEE 6/5460 – Water Resources Engineering David Rosenberg 4

Constraints (continued) • Ecological / Environmental – Endangered species? In-stream flow requirements? Water quality issues? Habitat areas? Land use? Abundance and viability of key indicator organisms? • Institutional – Applicable local/state/federal/international laws? Who makes them? Who enforces them? – Water rights? Tradable? – Governance, rate charging or taxing authority? Accountability? • Social / Cultural – Valuable archeological, religious, historical or other sites affected? Water-use practices impinged? CEE 6/5460 – Water Resources Engineering David Rosenberg 5

Implications of constraints • Planning – Options to be included / ruled out? Optimal? Under what metric? What are trade-offs? • Design – What structures are possible? At what cost? Impacts? Nonstructural alternatives? • Operations and management – Requirements for projects / facilities (e. g. , releases from storage, conjunctive management, timing, etc. )? • Policy development – Change laws or institutions to improve management or relax constraints on design / operations? Compensate injured parties? CEE 6/5460 – Water Resources Engineering David Rosenberg 6

From where does that water come? What volume of water do you + your family/housemates use at your house in a typical week? How much do you pay for it? Why are you taking this class? What aspect(s) of class are you most looking forward to? Prior water resources engineering experience? If so, what? Is there anything else that I should know that may help or impede your learning in this class? CEE 6/5460 – Water Resources Engineering David Rosenberg 8
