The Brixenbach valley is a small Alpine torrent catchment (9.2 km², 820–1950 m a.s.l., 47.45°, 12.26°) in Tyrol, Austria. Intensive hydrological research in the catchment since more than 12 years, including a hydrogeological survey, pedological and land use mapping, measurements of precipitation, runoff, soil moisture and infiltration as well as the conduction of rainfall simulations, has contributed to understand the hydrological response of the catchment, its subcatchments and specific sites. The paper presents a synthesis of the research in form of runoff process maps for different soil moisture states and precipitation characteristics, derived with the aid of a newly developed Soil-hydrological model. These maps clearly visualize the differing runoff reaction of different subcatchments. The pasture dominated areas produce high surface flow rates during short precipitation events (1 h, 86 mm) with high rainfall intensity, whilst the forested areas often develop shallow subsurface flow. Dry preconditions lead to a slight reduction of surface flow, long rainfall events (24 h, 170 mm) to a dominance of deep subsurface flow and percolation.

Brixenbach 研究流域：根据土壤水分状态和降水特征量化一个小型高山流域的径流过程比例

Brixenbach 山谷是一个小型的高山激流集水区（9.2 公里², 820–1950 m asl, 47.45°, 12.26°) 在奥地利蒂罗尔。12 年来在流域进行了密集的水文研究，包括水文地质调查、土壤和土地利用测绘、降水、径流、土壤水分和渗透的测量以及降雨模拟的进行，有助于了解流域的水文响应。流域、其子流域和特定地点。该论文以不同土壤水分状态和降水特征的径流过程图的形式对研究进行了综合分析，该图是在新开发的土壤水文模型的帮助下得出的。这些地图清楚地显示了不同子汇水面积的不同径流反应。在短暂的降水事件（1 小时，86 毫米）具有高降雨强度，而森林地区通常会形成浅层地下流。干燥的先决条件导致地表流量略有减少，长时间的降雨事件（24 小时，170 毫米）导致深层地下流和渗透占主导地位。
