Who Owns
the Water?

A river crosses boundaries, but authority stops at them. Operate reservoirs, divide scarce water, and write rules for three basins whose geography makes cooperation necessary and conflict tempting.

The river never signed the treaty.

Every unit stored upstream can make electricity or provide drought insurance. It can also become a unit that does not arrive downstream when expected.

Your assignment

Manage one season in each basin. Your job is not to maximize a single score. It is to decide which risks are acceptable, who carries them, and whether a rule that seems fair in one river travels well to another.

Model rule

Water units and scores are teaching abstractions, not forecasts. The places, institutions, upstream-downstream relationships, and central tradeoffs are real; the arithmetic is deliberately simplified so the politics can be seen.

01

Read three different rivers

Select a basin. The diagrams are geographic system maps: they preserve flow direction and the important relative locations, while omitting minor tributaries and administrative detail.

Regional reference map using geographic coordinates and real country outlines. Rivers are generalized and the shaded basin boundary is approximate.

02

Operate the river before you divide it

Choose a water year and a reservoir strategy. Storing, smoothing, and releasing the same inflow create different geographies of power, risk, timing, and trust.

Steady release in a normal year
Available downstream12 units
Reservoir security60 / 100
Initial trust58 / 100
03

Divide what reaches the negotiating table

Allocate every available water unit. The stakeholder list changes with the basin. In a dry year, the sum of reasonable needs is deliberately larger than the river.

12 units remain of 12
04

Write rules before the next drought

You have five negotiation points. Build one agreement and compare how it performs in all three basins. Institutions matter, but the same institution does not solve the same problem everywhere.

Select rules to see which basin gains most, which problem remains, and what your agreement quietly asks somebody to sacrifice.
05

Build a geographic explanation

Select three evidence cards. The lab will assemble an argument from mechanisms you observed. No answer is stored or submitted.

Your explanation

Choose three evidence cards to construct an argument.

Sources and model notes

Regional country outlines are adapted from Natural Earth public-domain map data. River routes use geographic coordinates but are generalized for legibility; shaded basin extents are approximate teaching guides rather than legal or hydrologic boundary files.

Nile cooperation and basin monitoring: Nile Basin Initiative and its Basin Management Plan. Mekong hydropower, fisheries, sediment, and basin planning: Mekong River Commission publications and the Sustainable Hydropower Development Strategy.

Colorado River rules and current post-2026 planning: U.S. Bureau of Reclamation. The activity treats Tribal nations as governments and rights holders, not merely another interest group. Scores are illustrative teaching outputs, not hydrologic or legal predictions.

Iraq: Layered Geographies Chapter 5 · Do Geography Iraq: Layered Geographies Can one border contain several nations, shared rivers, unequal resources, and cities that belong to more than one story? Turn the layers on, choose a political arrangement, and discover why maps clarify problems without solving them. Your task Imagine that you are advising a constitutional convention. Your goal is not to draw a “perfect” map. It is to choose an arrangement that reduces conflict while preserving livelihoods, movement, and access to resources. Important: This is a simplified learning model, not an ethnic census or a proposal for partition. People are mixed, identities overlap, and every sharp boundary below conceals local complexity. 1. Read the layers Turn layers on and off. Notice which patterns align—and which stubbornly refuse.

Draw the Line: The Geography of Representation Interactive geography lab Draw the Line The voters stay where they are. The population stays equal. Only the boundaries move, and political power moves with them. Step 1 Draw Step 2 Judge Step 3 Law Step 4 Cases Step 5 Decide 1 One state, many possible maps Mapporia has 640,000 people in 64 equal-population blocks. It needs four districts of exactly 160,000 people. Begin with a preset, then swap blocks to change the boundaries without changing district population. This is a teaching simulation, not a real electoral map. Each block contains 10,000 people. Vote and community patterns are synthetic but geographically plausible. Map layer ...
