WaterFutures/water-futures-battle: The Battle of the Water Futures [Data and Software - v0.5.0]

Release Date: 16th March 2026 This release addresses the community's feedback on the dynamic topology and introduces several new features for the evaluator. It also fixes the municipality elevation values that were incorrect in the previous release. What's New Data Municipalities: added main_destination_municipality column, representing the municipality inheriting the connections/pipes. Connections: added pipes_decommission_dates, replaced_by, and replaces columns to fully describe pipe and connection presence over time. Connections: added usable_in_2025 column, indicating which connections are available for participant interventions. Code Export intermediate results for modelled entities (demands, solar yields, etc.) Export EPANET network files with selected week demands or weekly average demands Export peak demands Apply interventions and policies What's Changed Data Municipalities: reduced elevations for some municipalities to improve tractability. Sources: adjusted capacities to better reflect proximity to demand centres. Connections/Pipes: revised pipe options for several connections; disabled connections between high- and low-elevation areas in Gelderland and Limburg. Connections/Pipes: new ID naming convention — IDs below 2000 are defined from the start; IDs between 2000–3000 exist only in the historical period; IDs above 3000 are defined for 2025 onwards. EPANET networks: updated to reflect current values and all possible interventions (disconnected sources are possible future sources, pipes with 0.0001 diameter are possible connections). Problem Description (PDF and Website) Minor clarifications addressing the most frequently asked questions. Expanded the section on municipality dissolution and connection inheritance. Updated the appendix to reflect input file changes. Rules and Information (Website) First deadline extended by one week. Important Notes The evaluator is still incomplete. Future patch releases of the Python library (0.5.x) will add the remaining features (e.g. complete hydraulic simulations).
