A dependable long-term hydrologic prediction is essential to planning, designing and 12 management activities of water resources. A three-stage indirect multi-step-ahead prediction model, 13 which combines dynamic spline interpolation into multilayer adaptive time-delay neural network 14 (ATNN), is proposed in this study for the long term hydrologic prediction. In the first two stages, a 15 gro...

Soil depth and texture exert strong controls on the spatial distribution of water and energy fluxes and states in semiarid watersheds. As a result, realistic representations of the spatial soil characteristics within watersheds are important for the improvement of process-based distributed hydrologic modeling applications. In this study, we evaluated the effects of combinations of soil thicknes...

[1] Relationships between channel characteristics (e.g., mean depth, water surface width, mean velocity) and discharge, known as hydraulic geometry (HG), have been extensively used by hydrologists and geomorphologists since the seminal work of Leopold and Maddock [1953]. On the basis of recent empirical evidence that the parameters of at-site HG depend systematically on the contributing area (s...

Ecohydrology is the science that studies the mutual interaction between the hydrological cycle and ecosystems. Such an interaction is especially intense in water-controlled ecosystems, where water may be a limiting factor, not only because of its scarcity, but also because of its intermittent and unpredictable appearance. Hydrologic dynamics is shown to be a crucial factor for ecological patter...

Hydrologic processes in depression-dominated areas are controlled by the spatial distribution of surface depressions and their dynamic hydrologic connectivity. Existing models often utilize lumped ways to handle depressions, hence features lost this simplification process. In study, a unique watershed-scale, semi-distributed model accounting for connectivity (HYDROL-DC) is developed functionali...

Sites with indicators of hydrologic disturbance had lower species rich...

Introduction Forefoot pain in Rheumatoid Arthritis (RA) is associated with functional and structural changes at the MTP joints. Previous cadaveric studies have suggested that forefoot deformities in RA might result from the failure of a complex ligamentous system and displacement of the plantar plates (PP). MRI and high resolution ultrasound (HRUS) have been reported to identify the PP and visu...
