Special Issue Information

Dear Colleagues,

Watershed ecological hydrology, a new interdisciplinary subject gradually developed after the 1980s, is an interdisciplinary science for exploring the interaction between plants and hydrological process, and for explaining ecological patterns as well as the hydrological mechanism of ecological process. The purpose of ecohydrological research is to deepen the understanding of ecological and hydrological processes and to provide a theoretical basis for restoring and renovating a harmonious ecohydrological environment. Specifically, exploring the interaction between ice and snow frozen soil precipitation/groundwater ecological environment has been raised concerns globally. A deep understanding of the correlation between watershed ecosystem and hydrological process and designing an integrated ecological restoration technology system needs to be further addressed in the field of watershed management and development.

Thus, this Special Issue aims to disclose novel basis, feasible approaches, and innovative perspectives on hydrology as well as watershed eco-hydrology, to reveal the role and significance of different landscape zones in the hydrological process and in maintaining the ecological environment, to promote the effective control and regulation of the ecological hydrological process and function, to provide the scientific basis for handling the ecological water demand, vegetation restoration, and ecological environment construction issues, and to propose reliable measures and reference for other issues, such as watershed water resources evaluation and management and water consumption efficiency, and finally to realize the sustainable utilization of watershed water resources.

This issue seeks to utilize novel approaches and innovative perspectives to deal with hydrology as well as watershed ecohydrology issues, but not limited to those above. Other hydrology and watershed-related contents are also desired.

This study presents an enhanced variant of the priority-flood based algorithm proposed by Wang and Liu for treating depressions in digital elevation models (DEMs). The enhanced variant redefines spill elevation, the key concept of the original algorithm, as the lowest elevation that a pixel needs to have to ensure a non-ascending path toward the border of the DEM, plus the larger of a small number (~0.001) and the difference between the unaltered elevation values of the focal pixel and its immediate downhill neighbor. This redefinition is adopted to obtain an intermediate elevation surface to direct flow and ultimately to carve the original DEM. Each carving starts from a depression bottom and propagates downstream until a downhill cell is guaranteed in the original DEM. Tests of these algorithms on a complex terrain of the 260,000 km2 Sichuan structural basin in China shows that the enhanced algorithm maximally preserves the original flow directions and extracts realistic drainage networks. Retaining the relative heights, and therefore flow directions, of cells within depressions allows the new algorithm to offer a depressionless DEM with small modification of its origin for further hydrologic applications. The enhanced depression treatment algorithm is provided as the freely available tool BNUSinkRemv. Full article
