Best management practices for landscapes include adapting them to rainfall extremes that have an impact on surface runoff. A critical profile (CP) is a location where a path of concentrated surface runoff might enter an inhabited area causing potential damage, e.g. by flooding, water erosion and torrential mudflows. Critical profiles have been determined using modified methodological guidelines for identifying critical points by the T.G. Masaryk Water Research Institute in Prague, 2009. In the model watershed Drevenica (117.27 km²), 27 profiles have been identified, where concentrated flow paths and the boundaries of built-up areas intersect. Four of the profiles have contributing areas of 0.3–10 km², average slope ≥ 3.5% and the share of arable land ≥40% as well as the critical conditions indicator according to the methodological guidelines and have been verified in terrain. Surveys and analysis also pointed out that another three profiles have indications of erosion runoff during rainfalls of varying intensity. By modifications of the original thresholds, these profiles have been included as critical. The lower threshold for contributing area was reduced to 0.2 km². A new set of parameters was added by the authors, namely the proportion of land with higher soil erosion risk levels (SERL) 2 to 5, exceeding 20% and threshold surface runoff volume ≥ 6000 m³. Critical profiles with their contributing areas are prime candidates for multi-functional ecological engineering measures.

景观的最佳管理实践包括使其适应对地表径流产生影响的极端降雨。临界剖面（CP）是集中地表径流路径可能进入居住区造成潜在损害的位置，例如洪水、水侵蚀和急流泥石流。布拉格 TG Masaryk 水研究所于 2009 年使用修改后的确定关键点的方法指南确定了关键剖面。在模型流域 Drevenica（117.27 km ²）中，已确定了 27 个剖面，其中集中的水流路径和边界建成区相交。其中四个剖面的贡献面积为 0.3–10 km ²，平均坡度≥3.5%，耕地比例≥40%，以及根据方法指南的关键条件指标，并已在地形中得到验证。调查分析还指出，另外三个剖面有不同强度降雨期间侵蚀径流的迹象。通过修改原始阈值，这些配置文件已被列为关键配置文件。贡献面积下限降低至0.2^平方公里。作者增加了一组新的参数，即土壤侵蚀风险等级（SERL）2至5级、超过20%且地表径流量阈值≥6000 m 3 的土地^比例。关键概况及其贡献领域是多功能生态工程措施的主要候选者。
