Runoff generation mechanisms
Webb15 apr. 2024 · In contrast, quickflow was almost entirely related to groundwater fluctuations at SHW. We showed that co-located measurements of soil moisture and … Webbquantify the spatial variability of HAAs based on two runoff generation mechanisms (RGMs), SOF and IOF. An MCE will not definitively quantify the presence of runoff flow pathways; rather, it will predict where HAAs could occur based on environmental conditions that facilitate specific RGMs.

Precipitation events can evoke different soil moisture responses with depth through the soil profile,… 5 PDF Hysteresis in streamflow‐water table relation provides a new classification system of rainfall‐runoff events
WebbDue to long−term extensive agricultural irrigation, the North China Plain is faced with a serious groundwater overdraft problem (Li et al., 2024), which has caused a sharp decline in the groundwater level, changing the original hydrophysical processes of the area and further affecting the relevant runoff generation mechanisms [16,17,18]. Webb15 dec. 2006 · In the past four decades, several studies on the runoff generation mechanisms in headwater streams have been performed (e.g., Tsukamoto, 1961, Dunne …
Webb26 maj 2011 · Runoff generation in headwater catchments toward the eastern part of the catchment was dominated by saturation excess mechanism, whereas runoff generation in subcatchments closer to the outlet was dominated by subsurface stormflow, with a systematic transition in their relative dominance along a gradient from the headwaters to … Webb12 maj 2024 · Figure 6Non-linear runoff generation in the Hydrological Open Air Laboratory (HOAL), Lower Austria. Scaled peak runoff of events plotted against scaled soil moisture at the beginning of these events. Each point represents one event. The panels refer to the flumes shown in Fig. 5, which represent different runoff generation mechanisms.
Webb27 maj 2024 · In the decades following Dunne , several other scholars proposed alternative conceptual frameworks to link dominant runoff generation mechanisms to properties of the physical environment. For …
