1. Most important stocks and flows - people - gas/oil/electricity for heating - water 2. Describe your findings people: my hometown is residential area with very limited workspace. Therefore people working have to commute. The traffic on the street and by train leaving my town is the flow. The present population at a specific moment in time is the population. The population at night might be the most important as based stock as based on this the infrastructure can be planned (e.g. schools etc.). On the other hand the stock at 10am in the city might be important too. By connecting the the data of the population at night and the population at 10am there might be an indication of the outgoing flow of people which can be used to plan the streets and train offering. gas/oil/electricity for heating: to make life easier I choose gas and only apply the concept to about 11 houses that are connected with a central tank for the gas heating. The amount of gas in the tank is the stock. The amount of gas used by the 11 houses every day is the flow. With the flow of the consumed gas in the heating process the person in charge of the gas tank can predict when to organize new gas for a refill of the tank. This is an important planning as in our area in winter time it can be very cold and heating is crucial. The same concept can be applied in a bigger scale for the whole town, for illustration the example of 11 houses made sense to me. water: my home town has a river. The height of the water level might be the stock. The amount of water passing by is the flow. It is obviously that if the stock is to high the flow of water might change direction which is definitively not a good thing in this place :-). With the information of the stock (water level) and the flow of water the planner in the wider area can make decision about how much water might be released or if a warning to the community might be issued for high water risk. Combining the information might help to prevent from a disaster by steering and increase security. 3: how could they change in the future for benefit of the area people: by getting more people in the stock there might be a fair chance that also the flow of tax return might increase which on the other hand allows the city planner to build more infrastructure gas/oil/...: by having more efficient houses (better isolation) the demand for gas might be reduced. This would lead to lower flow of certain pollution which might improve the air quality in the area. water: This is a tricky one as I have chosen a river. Having more water could be a risk as, while having less water would be not good to. I would assume that more water would allow a better steering of the flow and with some water energy technology there would be the possibility to gain electricity from the flow on a more constant basis which would lead to a lower flow of engergy due to local production.
