siltlagen

Could you clarify what you mean by "siltlagen"? Is it a real statute or regulation from a specific country, a historical term, or a fictional/conceptual topic? Also, should the article be in Swedish or English, and is there a particular jurisdiction or focus (environmental law, civil engineering, sediment management, history) you want covered? Once I have that, I’ll write a concise, neutral wiki-style article under 300 words.
