| Description: | Hydrological connectivity describes the degree of links between the spatio-temporal pattern of distributed hydrological variables within and across landscape elements and hence it determines the ease with which water may move across a landscape or through a river system. Connectivity occurs across a wide range of spatial scales from macropores to landscapes. The connectivity of sub-surface macropores can be described as networks which are common, nearly ubiquitous, and often dictate how water percolates through the soil, runs down the hillslope, and moves across the watershed. At the landscape scale, spatial patterns of soil moisture determine the areas of runoff generation, transmission and infiltration. New techniques enable the measurement and modeling of these processes to give insight into hydrological processes at a range of scales. Contributions are therefore solicited that consider theoretical definitions, innovative field investigations, landscape indices and modeling approaches to hydrological connectivity from the sub-surface macropore flow scale to the whole basin. |
