In many ways, hydrologic modeling is more an art than a science, and it is likely to remain so. Predictive hydrologic modeling is normally carried out on a given catchment using a specific model under the supervision of an individual hydrologist. The usefulness of the results depends in large measure on the talents and experience of the hydrologist and....understanding the mathematical nuances of the particular model and the hydrologic nuances of the particular catchment. It is unlikely that the results of an objective analysis of modeling methods ...can ever be substituted for the subjective talents of an experienced modeler. League & Freeze (1985)
There you have it, why experience and judgement tend to outweigh most other considerations when it comes to finding the right person for the job. Much like a watershed, a person can have many intangible quirks and qualities that in some cases make no difference and in other cases make all the difference. Experience and judgment are definitely qualities, but they are broad terms and it is tough to always pin down exactly what each is.
So what is experience and why is it important, can’t you intuitively figure anything out if you’re smart enough? Possibly, but the amount of time granted each of us is not infinite. Experience means you’re more likely to see what you’ve seen before. You’re more likely to recognize patterns, problems, and solutions. You’ll pick up on things more quickly, have a deeper understanding and know how to get things done in a timely fashion. You’ll also be more likely to know when something is beyond hope.
The weird thing with experience is the way in which people get it. Parents will expose their kids to certain things hoping for precise results and people will get involved with things looking for a certain outcome. More often than not though, events turn out differently. It can be to the point that the only way to guarantee an outcome won’t happen is to think about it happening. But, you usually do get something unexpected out of any experience and do learn something if you happen to pay attention. So therefore, the experience does help, just not in the way in which it was expected. It is always good to leave a little room open for the unexpected.
So what about judgment? Well, with a watershed there is literally an infinite amount of data that could be gathered and used to model it. Once again, the problem is time and resources. If both were infinite you could gather as much data as you wanted. But since this is reality, you need to make a judgment call on what data to get and then another judgment call on how to interpret that data. This holds true for anything. Every situation involves making a judgment call with the data available. Of course sometimes judgment tells you to get more data. But eventually you have to make a choice. So what is the best way to improve your judgment? With experience.
Given this, one can come to a conclusion and say, maybe I should just be looking for experiences and not planning any specific outcome. Try a variety of things. I can’t do the same thing over and over again and expect to get as much out of it. The law of diminishing returns will take effect. Challenge yourself, and see what there is to learn and how it can help in the future. So whether it’s a new career or a game of pool, bring it on.
