A framework for quantifying hydrologic effects of soil structure across scales

چکیده

Abstract Earth system models use soil information to parameterize hard-to-measure hydraulic properties based on pedotransfer functions. However, current parameterizations rely sample-scale which often does not account for biologically-promoted structure and heterogeneities in natural landscapes, may significantly alter infiltration-runoff other exchange processes at larger scales. Here we propose a systematic framework incorporate corrections into functions, informed by remote-sensing vegetation metrics local texture, numerical simulations investigate their effects spatially distributed areal averaged partitioning. We demonstrate that small scale features prominently the hydrologic response emerging scales upscaled must consider spatial correlations between texture. The proposed allows incorporation of hydrological with appropriate considerations contemporary functions used land surface parameterization.

Quantifying soil complexity using network models of soil porous structure

This paper describes an investigation into the properties of spatially embedded complex networks representing the porous architecture of soil systems. We suggest an approach to quantify the complexity of soil pore structure based on the node-node link correlation properties of the networks. We show that the complexity depends on the strength of spatial embedding of the network and that this is ...

„ Field observations of soil moisture variability across scales ” by

maximum values occurring at mean moisture contents of 0.17 cm 3 /cm 3 and 0.19 cm 3 /cm 3 for the 800 m and 50-km scale, respectively. Based on these data, they derived empirical relationships between the coefficient of variation and the mean soil moisture content in order to estimate the uncertainty in field observations of mean moisture content. The authors are to be commended for providing t...

Effects of detailed soil spatial information on watershed modeling across different model scales

Hydro-ecological modelers often use spatial variation of soil information derived from conventional soil surveys in simulation of hydro-ecological processes over watersheds at mesoscale (10–100 km). Conventional soil surveys are not designed to provide the same level of spatial detail as terrain and vegetation inputs derived from digital terrain analysis and remote sensing techniques. Soil prop...
