就自然状况的破坏而言,仅举1970年洪水流经巴莫堡水闸上游的莱因—美因—多瑙河河口雷格尼茨河段的情况就足以说明。由于莱因—美因—多瑙河14万米~3的输沙量淤积在河口处,致使完全碍航达五个月之久。又持续了一个月后,才能单线航行。为了避免这类情况再次发生,什威尼尔富水利局提出了持久性的整治方案。在雷格尼茨河口处开挖沉砂池,邻近沉砂池旁修筑一条长达450米的导流坝。这是最有效、最经济的方案。沉砂池沉积洪水携带的泥砂,在正
As far as the destruction of the natural conditions is concerned, the mere mention of the Regnitz section of the Rhine-Main-Danube Estuary upstream through the floodgates of the Babumburgh in the 1970 floods is sufficient. As the Rhine-Main - Danube 140,000 ~ 3 sediment deposition at the estuary deposition, resulting in complete impetus for up to five months. After another month, it can sail on a one-line. In order to prevent this from happening again, the SWVFW proposed a lasting remediation program. Dredging a grit chamber at the mouth of the Regnitz and a 450-meter diversion dam next to the grit chamber. This is the most effective and economical solution. Sediment pond sediment flood carrying sand, is positive
