| Popis: | A hydrological field station is established to measure storm water runoff from a 4300 m2 pervious catchment in an urban landscape. The objective is to explore potential flood early warning indicators and assess the consequences of runoff from pervious surfaces to urban drainage systems in addition to runoff from impermeable surfaces. Soil volumetric water content and soil-water matric potential are measured in several sensor clusters in the catchment. It is found that measured surface runoff and soil volumetric water content are well correlated while matric potential is an on-off indicator, indicating if soil volumetric water content decreases slowly, reflecting low infiltration capacity. |
