creating dampness on the river. establish a rule for everyone to implement rainwater harvesting, as rain falling on houses ends up on the road, causing the drains to become blocked.
to construct high and strong banks
i used to have a 20-stall barn that i leased, and through that experience, i learned a lot about what i would want if/when i built my own. i never did; i have always had to make do or make changes in an already existing facility. it had automatic waterers (heated) in the stalls, half of the barn was built against a hill, so that on one side, half of the barn was underground. the whole area above the stalls was for hay storage, to be dropped down into the feeders in the stalls. speaking of the stalls, way down under the stalls were railroad ties, then 18 inches of sand on that, shavings needless to say, the stalls never got wet. we picked the stalls twice a day, and the barn smelled like shavings and clean horses all the time. now, the waterers were always a headache, and you never knew if a horse was drinking or not, and if there was ever a short in one of the waterers, and a horse got shocked even one time, he would never go back and drink from it. so i turned off all of the waterers and hung buckets in the stalls and pulled a hose down the aisle to fill them. still the best way, more work, but you can keep track of what is going on with your horse. oh yes, the overhead hay storage was a dusty headache; it also made the barn hotter when the loft was full and impaired the circulation, even though there were several vents. i would try not to even let anyone up there while there were horses still in the stalls because of the dust that was created by walking in the loft. one thing that i did appreciate was that half of the barn was against the dirt; even in the summer, it was cool in the barn. i also consider it important to have a solid window in every stall that opens wide enough for the horse to comfortably get his head out. there are lots of reasons for this, not to mention the fresh air, but it lessens the boredom, which in turn lessens the weaving, cribbing, and kicking the stalls. i like concrete for the wash rack and alley, and it should be wide enough that horses can be tied on either side and still be groomed. also, if the wash stall has a window, just like the stall window, your horses will walk in much easier because they can see out and don't feel like they are going into a dead end; you can always close it when you get your horse tied. of course, you will want a hot water heater just for the wash rack. if money isn't an issue, a small bathroom is a must, and well-planned, locked tack rooms i always dreamed of having, within the large tack rooms, partitions for each individual's tack that they could lock up and know that their stuff would never be used or touched by anyone else while they were gone. keep in mind, everyone that boarded there wasn't family, so that was a big issue that had to be addressed on a regular basis. boy, i could go on and on; i guess i already have. no, i don't like mats; i have tried them, would rather have good drainage with shavings. i personally don't like cross ties, but every stable has them and uses them, and most of the time, successfully, but then there is always the horse that just flips for no reason, and you have to haul them off seriously. i would prefer individual places in front of the stall meant for tying, along with a blanket bar out of reach of where the horse can't chew. oh yeah, a doctoring/clipping chute somewhere in an out-of-the-way but well-lit area. i guess i'd better stop; we all have lots of ideas. hope this helps a little, and one more thing, you never have too many lights with convenient places for switches.
in the short term, i think better sewers could solve the problem. in the long run, climate issues would need to be addressed, as these will lead to more extreme weather and, consequently, more flooding.
built out the sewers all over the city, take advantage of people's cellars (basements) to manage rising water levels, create more park areas to absorb rain instead of parking lots, and construct roads to function as rivers to direct the water to lakes or the sea.
manage stormwater at the surface and ensure it can drain away safely when there is a large amount.
absolute prevention is impossible. however, problems can be reduced. this always has to be done in combination with improving the quality of life in the area (traffic, litter, parking, etc.).
better sewers
we cannot avoid flooding right now as the climate takes time to adjust to our actions, but we can do something to minimize the damages and we can at the same time take preventive action which will show effects in 10-20 years' time. to adapt to the flooding, we need to construct elevated surfaces where there is a security risk, i.e., underground stations. furthermore, the drainage needs to be enlarged everywhere as it cannot handle the floods that are occurring nowadays. the preventive actions are to lower our greenhouse gas emissions, i.e., we must let our energy be supplied by more renewable energy sources such as windmills, hydropower, geothermal energy, and solar power.
more urban green spaces. less impermeable surfaces. bigger drainage systems.
short term: lar (in english local drainage of rainwater) and repairs of the drainage system.
long term: stop climate change.
it's not a problem yet. for the future, could we try to stop global warming?
i know they removed some houses in odense to make room for a big basin. i think people have to move away from the areas with high flood risks. i don't think it will be completely possible to solve the problems by introducing larger drainage systems combined with sustainable drainage systems.
mapping the areas of the city that are at risk of flooding and avoiding excessive paving and construction in those areas. adding more green spaces in the city to reduce runoff.
better sewer system
to my knowledge, it's mainly a problem in the northern parts of odense. in stige, they often have floods by the harbor, and a good solution might be to expand the sewage system or have pumps for flooding that could drain the areas, and maybe store the flood water for some kind of reuse, considering its quality.
deal with the water locally - for example, infiltrate rainwater instead of directing it to the sewer system.
i don't know odense.
first, there are only some areas with flooding problems, but not all. to me, a good solution is an integrated approach that combines both conveyance systems and sustainable solutions.
