Deep Dive: Designing the dynamic irrigation and water systems in Timberborn

Single-layer 2D water model adapted from erosion simulation; tiles linked to four neighbors by virtual pipes; ticks every couple of hundred ms; water levels equalize; evaporation; recurring droughts grow harsher and ramp source strength down early; hard-coded dam values avoided because they caused oscillations; moisture falls off per tile and sharply uphill.
