Immersive Model for Lake Mead Based on the Principle of Divide Reservoir Inflow

The purpose of this immersive online collaborative model is to give collaborators the opportunity to immerse in and personify water user roles for a Lake Mead model based on the principle of division of reservoir inflow. The model works on the principles of A) Divide reservoir inflow, B) Subtract evaporation, and C) Users consume and conserve within their available water, others choices, and real-time discussion of choices. There are six users in the model - Reclamation, California, Arizona, Nevada, Mexico, and Tribal Nations of the Lower Colorado River Basin. We see uses of the tool for two purposes:

1) As researchers we want to learn: Why basin partners choose assumptions and how extreme; Why and how basin partners manage their risk of uncertain future water supply; Which new insights they take from a model session.
2) Provoke thought and discussion to: i) Stabilize and recover reservoir storage under conditions of low storage and low inflow, and ii) Give users more autonomy to manage their conflicting vulnerabilities to water shortages.

The README file below provides more background on the model, the 3 key ideas, and instructions to download the model file, move into Google Drive, invite colleagues/co-workers/friends/family, and guide an immersive model session.

本沉浸式在线协作模型旨在为协作方提供参与基于水库来水分流原则构建的米德湖（Lake Mead）模型，并沉浸式扮演各类用水角色的机会。该模型遵循三大核心原则：A）水库来水分流，B）扣除蒸发量，C）用户需在可用水量、他人决策及实时讨论的框架内开展用水与节水操作。模型包含六类参与主体：美国垦务局（Reclamation）、加利福尼亚州、亚利桑那州、内华达州、墨西哥以及科罗拉多河下游流域（Lower Colorado River Basin）原住民部落。

该工具的应用目的分为两类：
1） 供研究人员开展相关研究：探究流域合作伙伴为何选择特定假设及其极端程度；流域合作伙伴如何应对未来供水不确定性带来的风险；以及参与模型会话后他们获得了哪些新认知。
2） 引发思考与讨论：i）在水库蓄水量与来水量双低的条件下，稳定并恢复水库库容；ii）赋予用户更多自主权，以应对水资源短缺引发的各类冲突性脆弱性问题。
