🌊 InfoWorks Pollutograph Deep Dive 🌊

This informative section is especially dedicated to Water Quality Simulations enthusiasts 🌏💧.

---

💡 Introduction to Pollutograph:

A Pollutograph 📈 in InfoWorks symbolizes a series of water quality inputs into a system. This comprehensive graph outlines concentrations for sediment fractions, dissolved determinants, and measures the potency of attached determinants. You'll apply this input at specific nodes, links, 2D point sources, 2D line sources, or 2D boundaries using the 🎨 Profile Properties Dialog.

---

🔗 Integration with Inflow or Level Event:

The Pollutograph collaborates seamlessly with an Inflow or Level event. While the latter provides a flow measurement, their combined effort defines the actual pollutant inflow. For every pinpoint that's determinant input is defined in the Pollutograph, a hydrograph must also be distinctly defined in the Inflow or Level event.

---

🔔 Important Notes:

• Level hydrographs are particularly used to offer inflow data at Outfall nodes or 2D boundaries. This reflects the changing level in massive water bodies, such as rivers or oceans. Once this level surpasses the outfall level, a backflow into the system can emerge 🌊↩️.

• Inflow hydrographs have a more versatile application, valid at 2D point sources, 2D line sources, 2D boundaries, links, and most node types, with the exception of Outfall nodes.

• Be vigilant! 🚫 Pollutograph events shouldn't be used alongside Time Series Database objects during simulations.

• To harness a pollutograph in a simulation, simply incorporate the pollutograph in the 📅 Pollutograph box present in the Schedule Hydraulic Run View.

---

✨ The Core Components of Pollutograph:

Pollutographs are showcased and modified using a specialized version of the Event Editor. Various tabs 📑 guide the user, each signifying a unique determinant inflow:

• Sediment Input: The sediment tabs (SF1 and SF2) represent time-varying sediment concentration 🏞️.

• Dissolved Pollutant Input: These tabs offer a comprehensive insight into time-varying concentrations for dissolved determinants. Additionally, fixed potency factors for determinants attached to sediment fractions can be defined here, if applicable 🧪.

• Attached Pollutant Potency: These tabs illustrate time-varying potency factors for attached determinants. It's worth noting that these factors, when varied with time, will override any fixed potency factor 📌.

• Detrital Pollutant Input: These determinant tabs are vital in the calculation of growth and decay of Algae and Macrophytes 🌱.

Each determinant is meticulously examined independently. For an exhaustive understanding of the determinants, diving into the Water Quality Determinants section is recommended 📚.

---

🔄 Sub-Events & Profiles Breakdown:

Pollutograph events, akin to many other event types, are bifurcated into:

• Sub-events: These are specific time intervals during which an input to the system is recorded ⏳.

• Profiles: These describe the input at a singular point 📍.

Delving deeper into how InfoWorks ICM treats sub-events and profiles can be enlightening. It's fascinating to observe that each determinant type can be unique, having varying sub-events with distinct start and end times.

🌐 SWMM 5.2.3 Inlet Workflow: A Comprehensive Guide 🌐

The journey of modeling inlets using the Storm Water Management Model (SWMM) is both intriguing and structured. Here's a deep dive into the workflow, tailored for a street and sewer drainage system:

1. 🛣️ Layout both the street and sewer networks: Picture this as laying out the blueprint 📐 for your city's drainage system. Determine where your roads, channels, and sewer pipes intersect and flow. A solid foundation at this stage ensures a smooth workflow later. Tools like GIS 🌍 can provide valuable spatial insights.

2. 🌦️ Assign subcatchment runoff and user-defined inflows to street nodes: Think of this as guiding rainwater 🌧️ down specific paths. Allocate the runoff and specific inflows to nodes in your street layout, mapping the journey of every raindrop.

3. 🚧 Create a collection of Street cross-sections: Dive deeper into the anatomy of your streets. Imagine slicing the street vertically and observing its profile – that's your cross-section, showcasing the road, pavements, and gutters.

4. ⚙️ Assign specific Street cross-sections to street conduits: Like choosing the right outfit for an occasion, pick the right cross-section for each conduit. It should mirror the real-world structure of that street segment.

5. 🕳️ Create a collection of Inlet designs: Now, focus on the gateways for water – the inlets. Whether they're small, large, circular, or rectangular, design them to efficiently channel water away from the streets.

6. 🔗 Assign specific Inlet designs to streets: Place your inlets strategically on the streets. It's like setting up checkpoints 🚧 on a marathon route, ensuring stormwater has frequent entry points into the drainage system.

7. 🖥️ Set analysis options and hit 'Run' 🏃: Configure SWMM's brain 🧠, adjusting parameters to suit your needs. Then, let the magic happen. SWMM will simulate, predict, and present you with a model of stormwater movement in your setup.

8. 🔍 Review the results: After simulation, it's reflection time ⏳. Examine the flow spread and depth values. Are they within your safety and design limits? If not, it's back to the drawing board, tweaking your designs for better outcomes.

Remember, this guide provides a foundational understanding. Real-world scenarios might throw curveballs 🌀, demanding additional steps or considerations depending on unique challenges, local conditions, and design standards. Happy modeling! 🎉📊🌊

🔄🌊 Diving Deep into InfoSewer's Two-Pass Solution 🌊🔄

 🔄🌊 Diving Deep into InfoSewer's Two-Pass Solution 🌊🔄

InfoSewer's dual-pass approach is akin to a master chef's 🍲 two-stage cooking process. Each step, or "pass", brings out the flavor and depth of the sewer system's performance data. Let's understand this methodology by dissecting its two main phases.

🚀 Phase 1: Laying the Groundwork with Manhole Loads and Link Flows 🚀 Think of the first pass as prepping the ingredients 🥕🧅. It sets the stage for the entire simulation, just as chopping and marinating precede the actual cooking. InfoSewer begins its analysis by calculating manhole loads and exploring the flow dynamics of the connecting links.

• 🎯 Key Output: The initial d/D values pop out, much like a chef's taste test, giving a sneak peek into the final dish.
• 🔍 Primary Focus: This phase is all about groundwork - understanding manhole loads and estimating link flows.
• 📊 Use-case: Perfect for getting that preliminary snapshot 📸 of the sewer network, aiding in early decision-making.

🔥 Phase 2: Delving Deeper with Backwater, Surcharge, and Pressure 🔥 If the first pass was prepping, the second pass is the actual cooking 🍳. It dives deeper, using the base from the first pass, and brings in flavors of backwater effects, surcharge conditions, and system pressures.

• 🎯 Key Output: The adjusted d/D values and the HGL, much like the garnishing and plating, refine and complete the analysis.
• 🔍 Primary Focus: It's all about depth here - understanding backwater, surcharge, and pressure intricacies.
• 📊 Use-case: This is where the magic happens, ideal for in-depth analysis, risk assessments, and planning for those unexpected system hiccups.

🤝 Interplay Between the Two Phases 🤝 Much like in a recipe, where ingredients interact and depend on each other, the two passes in InfoSewer are interlinked 🔄. The second pass refines the first, often giving higher adjusted d/D values, much like how slow-cooking meat after marinating makes it more tender and flavorful.

❓ Why Adjusted d/D Matters ❓ The adjusted d/D is like the taste after adding spices 🌶️. Born out of the second pass, it's a more nuanced and detailed metric than the initial d/D. It reflects the intricate dance of hydraulic factors considered in the second pass, serving as a trusty guide for system assessments.

In essence, InfoSewer's Two-Pass Solution is a culinary journey 🍽️ through the complexities of sewer system modeling, each stage adding depth, flavor, and insights, culminating in a comprehensive and reliable model. Bon Appétit! 🎉🥂
