💧 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.
