SWMM5 - Emoji Code - In the land of urban sustainability, an ancient scroll 📜 named lidproc.c

 In the land of urban sustainability, an ancient scroll 📜 named lidproc.c held the secrets to mastering Low Impact Development (LID) practices. The essence of the scroll can be described as follows:

Chapter of Constants - "The Sacred Thresholds" ⚖️:

• STOPTOL: A revered boundary, set at 0.00328 ft, representing the integration error tolerance, which in earthly terms, is a mere 1 mm 📏.
• MINFLOW: A hallowed cut-off, a mere whisper of flow at 2.3e-8, equivalent to a gentle rainfall of 0.001 in/hr. It signifies dry, parched conditions 🌵.

Chapter of Enumerations - "The Layers of LID and Their Chronicles" 🌍:

1. SURF: The surface layer, where water first makes contact, dancing atop the land 🌧️.
2. SOIL: Deep beneath the surface, the soil layer lies, nourishing life and filtering the waters 🌱.
3. STOR: The storage layer, a reservoir holding back waters, releasing them only when the time is right 🌊.
4. PAVE: The crafted pavement layer, man-made yet harmonious with nature 🛤️.
5. DRAIN: The underdrain system, guiding waters, ensuring they follow the righteous path 🌀.

Chapter of LidRptVars - "The Chronicles of LID Metrics" 📊:

1. SURF_INFLOW: The tales of waters flowing into the surface layer 🌧️➡️🌍.
2. TOTAL_EVAP: Chronicles of the waters that ascend, turning into vapor, leaving the land to join the skies ☀️🌫️.
3. SURF_INFIL: Stories of the waters seeping into the surface, a gentle embrace 🌍💧.
4. PAVE_PERC: Narratives of water passing through the crafted pavements, a symbiotic dance 🛤️💦.
5. SOIL_PERC: Ancient tales of water journeying through the soil layer, nurturing life 🌱🌍.
6. STOR_EXFIL: Legends of waters seeping out from the storage reservoirs, moving beyond boundaries 🌊➡️🌍.
7. SURF_OUTFLOW: Chronicles of waters departing from the surface layer, journeying forth 🌍➡️🌊.
8. STOR_DRAIN: Stories of waters guided by the storage layer's drain, ensuring they tread the right path 🌀.
9. SURF_DEPTH: Depths of waters, ponded on the surface, reflecting the sky above 🌧️🌍.
10. PAVE_DEPTH: Tales of water depths within the pavements, a testament to man and nature's coexistence 🛤️💧.
11. SOIL_MOIST: Narratives of the soil's moisture, vital for life's sustenance 🌱💦.
12. STOR_DEPTH: Chronicles of the depths within the storage reservoirs, holding back waters with grace 🌊🌍.
13. MAX_RPT_VARS: The grand culmination, representing the zenith of all LID metrics 🌟.

And so, with each layer and metric, the essence of sustainable urban practices was captured, ensuring that cities thrived in harmony with nature 🌆🌱. The end. 🎉📖🌍.
