🌍 Model Inflow Guide 🌍
💧 Determinant Inflows:
Your model's inflows can originate from multiple sources. Here's a breakdown:
🍂 1. Surface Pollutants:
- Sediment Buildup: Sediment accumulates on subcatchment surfaces throughout the simulation. This sediment can carry pollutants.
- Sediment Fractions: Two distinct sediment fractions can be modeled, each having unique properties.
- Dissolved Pollutants: These infiltrate the network via gully pots at each node.
- Build-up Period: Execute a simulation for a build-up phase to stabilize sediment depth on the surface.
- Surface Pollutant Model: Calculates sediment and pollutant inflow from catchment surfaces and gully pots.
🚿 2. Wastewater Inputs:
- Wastewater Profiles: These determine inflows from a subcatchment's population. You can define concentration, potency, and pollutant multipliers over time.
- Data Needs:
- Per capita flow 🌊
- Average sediment concentration 🏖️
- Average dissolved pollutant concentrations 🧪
- Average potency factors 📊
- Multiplying factors 🔄
- 🔍 More details in the Trade and Waste Water Events section.
🏭 3. Trade Waste Inputs:
Trade Waste Profiles: Represent inflows from places like industrial premises.
Data Needs:
- Average sediment concentration 🏖️
- Average dissolved pollutant concentrations 🧪
- Average potency factors 📊
- Multiplying factors 🔄
🔍 More details in the Trade and Waste Water Events section.
🎯 4. Point Pollutant Inflows:
- Pollutographs: These are specific inputs into the system, used along with inflow or level events.
- Flexibility: Pollutographs offer more adaptability than regular wastewater events.
- Usage: Model irregular pollutant inputs, such as weekly industrial tank flushes.
- Content:
- Sediment fraction 🏖️
- Dissolved pollutant 🧪
- Pollutant attached to sediment 🪨
- Detrital pollutant 🍂
🏞️ 5. Sediment Fractions:
Description: Model two separate sediment fractions - Sediment Fraction 1 (SF1) and Sediment Fraction 2 (SF2).
Parameters:
- D50: Average sediment particle size 📏 (default: 0.04mm)
- Specific Gravity: Sediment density 🏋️ (default: 1.7)
🔍 More details in the Sediment section.
🌌 6. Conservative Determinants:
- Modeling: Determinants are viewed as conservative, unless decay parameters are specified.
- Interaction: These determinants don't interact with other variables and remain stable over time.
