🌊 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.

 🔄🌊 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! 🎉🥂

Emoji Sediment in ICM InfoWorks Network

 🌊 Sediment in Water Systems 🌊

This section is incredibly crucial when diving into Water Quality Simulations 🌧️🔬.

🚰 Sediment in conduits 🚰 In InfoWorks ICM, sediment layers in pipes have a story to tell 📖. They're treated differently by the hydraulic model 🌪️ and the water quality model 🌈. Picture this: InfoWorks ICM is like a theatre 🎭, and it showcases two different layers of sediment in pipes, each playing its unique role.

🛌 The Two Sediment Stars 🌟:

1. Passive Layer 🛏️ - This is the chilled-out layer. Think of it as the sediment that's lounging around, fixed and unchanged during any dramatic rain event. It's just there, minding its business.
2. Active Layer 🏃‍♂️ - This layer is the real action hero. During a water quality simulation, it can be eroded, transported, and deposited. It's the dynamic part of the sediment story.

📏 If you add the passive and active layers, and they make up more than 80% of the conduit's height, well, no more dramatic scenes for the active layer. It's a wrap; no more deposition.

💡 You're handed the director's chair 🎬. You decide whether the drama in the active layer during a water quality simulation affects the overall hydraulic story or not. This directorial choice is yours in the QM Parameters Dialog.

🚫 If you choose to ignore the active layer's dramatics for the hydraulic story, it might be a good idea to cap the sediment depth a bit, maybe at 10%, just so the hydraulic and water quality stories aren't worlds apart.

🌊🚰 Pipe Sediment in InfoWorks ICM 🚰🌊

🛌 Passive Layer 🛌: When sediment decides to take a break and just chill, you get the passive layer. It's fixed and doesn't change during any performance, acting mainly as a constriction on the stage (or pipe). How deep is this layer? Well, you set it using the Sediment Depth field for each conduit. Or, get fancy and define a unique set of Pipe Sediment Data for your show.

🏃‍♂️ Active Layer 🏃‍♂️: Here's where the action happens. This layer has one or two sediment stars 🌟, called Sediment Fraction 1 (SF1) and Sediment Fraction 2 (SF2). Each star has its own characteristics, like particle size and density. And if you want some behind-the-scenes control, you can tweak these characteristics in the Surface Pollutant Editor.

The active layer's drama is limited by: 📏 Maximum sediment depth - depth of Passive Layer

🏞️ River reach bed sediment 🏞️

Like a trilogy, the river section bed has three parts:

1. Active layer 🏃‍♂️: This is the top layer. It's dynamic and ever-changing. You set its thickness, and as sediment gets deposited, some of it goes to the layer below.
2. Deposited layer 🍂: Think of this as the middle child. It's made up of sediment that once was active but decided to settle down.
3. Parent layer 🌍: This is the base layer - the OG sediment. It's the river bed, and it only gets eroded if the deposited layer is all used up.

Remember, these layers tell the story of the river, its history, and its future. So, take the director's chair and make the tale epic 🎥🍿.

Unpacking the Two-Pass Solution in InfoSewer

 Unpacking the Two-Pass Solution in InfoSewer

InfoSewer's dual-pass methodology is a cornerstone for achieving a meticulous and comprehensive analysis of sewer system performance. The two distinct passes each offer a layer of insight into various facets of the system, particularly focusing on the depth-to-diameter ratio (d/D) and the Hydraulic Grade Line (HGL).

Phase 1: Laying the Groundwork with Manhole Loads and Link Flows

The first pass serves as the initial survey, setting the stage for the entire simulation. During this phase, InfoSewer calculates the loads for each manhole and estimates the flow dynamics in the links connecting them.

• Key Output: The primary yield from this stage is the initial d/D values, which are often used for preliminary mapping.
• Primary Focus: At this juncture, the main attention is given to calculating manhole loads and estimating link flows.
• Use-case: This is especially useful for generating an initial hydraulic snapshot of the sewer network, which can be invaluable for early-stage planning and decision-making.

Phase 2: Advancing the Analysis with Backwater, Surcharge, and Pressure

The second pass builds upon the foundational data gathered in the first. This phase engages in a more nuanced analysis by incorporating calculations for backwater effects, surcharge conditions, and intra-system pressure.

• Key Output: The adjusted d/D values and the HGL emerge as the critical outputs from this phase.
• Primary Focus: The emphasis here is on advanced hydraulic modeling, including backwater estimation, surcharge analysis, and pressure calculations.
• Use-case: The second pass is vital for risk assessments, emergency response planning, and other high-stakes decision-making processes.

Interplay Between the Two Phases

The two passes are not isolated events but rather interdependent processes that feed into each other. The second pass takes the first-pass data as a baseline but refines it to account for the more intricate hydraulic phenomena, often resulting in higher adjusted d/D values.

Why Adjusted d/D Matters

The adjusted d/D, born out of the second pass, usually exceeds the initial d/D computed during the first pass. This variation is not arbitrary but indicative of the complex hydraulic factors like backwater effects and surcharging that were considered in the second pass. As such, the adjusted d/D serves as a more reliable and nuanced metric for assessing system performance and associated risks.
