“How can we characterize the rate at which new biomass is created in water bodies?”

Water bodies can be the fabric of an ecosystem. Ecosystems are composed of living matter, also known as biomass. The rate at which new biomass is produced in water, or Biological Productivity in Water Bodies, is dependent upon the amount of sunlight that reaches the water, the nutrients in the ecosystem, the water temperature, the amount of mixing and clarity in the water, and the carbon availability. Biological productivity can drastically affect a water body system’s health, leading to eutrophication if not controlled.

“How can we make industrial parks more sustainable?”

Industrial parks are the foundation of much industrial activity. However, they can also create voluminous amounts of pollution. That’s where Eco-Industrial Parks come in. Eco-industrial parks establish circular economy practices through resource sharing and the reuse of manufacturing byproducts. Eco-industrial parks also strive to harness sustainable energy and reduce inefficiencies. Governments can adopt eco-industrial park strategies to build wealth and industrial capacity while avoiding excess environmental damage.

“How do governments create areas for industrial development?”

Industrial development can be a planning nightmare. It needs to be close enough to major transportation and infrastructure access, but far away enough from residential neighborhoods to shield people from pollution. One way to accomplish this is to designate areas as Industrial Parks. Industrial parks cluster industrial buildings in a specific area for optimal output. Industrial parks can focus on specific industries, allowing different businesses to work together for synergy. Industrial parks typically have industry-specific infrastructure such as high-power electricity lines, dedicated water towers, or commercial rail stops.

“What’s so special about orifices that extend into their container?”

Orifices are openings in containers. In water systems, they’re pipes that allow for gravity-based release. Orifices whose pipe extends into the tank itself are called Re-Entrant Orifices. For these orifices, the water will flow to the tube from all directions, leading to a sharp turn inwards and a significant stream contraction, leading to a jetting on the other end. These features lead to a smaller discharge coefficient, thereby limiting flow. Re-entrant orifices are useful for applications where flow downstream of the container must be controlled.

“How can we use rings to facilitate floodwater infiltration?”

Infiltration can be a very useful stormwater control method. However, too much water impacting the surface at once can overwhelm soil and hinder infiltration. We can address this by placing solid Drainage Rings in the Earth to store water while seeping it out at controlled rates to the surrounding dirt. Drainage rings are commonly surrounded by stone drainage media for additional support. Drainage rings are a central component of drywell systems.

“How can saltwater intrusion seriously harm forests?”

Saltwater damages freshwater trees. Consequently, saltwater intrusion into coastal forests leads to wide swaths of destruction, leaving Ghost Forests in its wake. Sea-level rise from climate change is already leading to a proliferation of ghost forests. Ghost forests are an increasingly common sight in the U.S. Southeast.

“What is the highest level of algal contamination for lakes?”

A lake’s trophic state index determines its algal power. Lakes at the highest end of the index (above 70) are classified as Hypertrophic Lakes. Hypertrophic lakes have very poor water quality and low water visibility. Algal overgrowth can be so intense that animals die off en masse from lack of dissolved oxygen.

“How can we use permeable material to improve drainage systems?”

Drainage systems transport water from one place to another. Sometimes, drainage systems will need additional material to improve performance and prevent soil clogging. This usually consists of Drainage Media composed of permeable material, such as crushed stone or plastic media with voids, surrounding the drainage system to assist with infiltration into nearby soil.

“How can we quantify algal bloom intensity?”

Algal blooms in water bodies result from high nutrient load and strong environmental conditions. The associated biological productivity can be measured by the Trophic State Index. The trophic state index captures the amount of light striking the surface of a water body, the concentration of particulate matter, and the physical measuring depth to determine the algal bloom intensity.
