0022-1694/$ see front matter 2012 Elsevier B.V. A doi:10.1016/j.jhydrol.2012.02.022 ⇑ Corresponding author. E-mail address: [email protected] (T.A. Russo). We present results of an observational and modeling study of the hydrologic response of a riparian wetland to controlled flooding. The study site is located in Poopenaut Valley, Yosemite National Park (USA), adjacent to the Tuolumne River. Thi...

WaSiM-ETH (Gurtz et al., 2001), a widely used water balance simulation model, is tested for its suitability to serve for flow analysis in the context of rainfall runoff modelling and flood forecasting. In this paper, special focus is on the resolution of the process domain in space as well as in time. We try to couple model runs with different calculation time steps in order to reduce the effor...

[1] Based on the diffusion equation and Darcy’s law, Criss and Winston (2008b) developed the one-parameter analytical subsurface flow diffusion hydrograph model to represent the theory of rapid displacement of ‘‘old’’ aquifer water and shallow pore water following rainfall events. We developed a two-parameter analytical surface flow diffusion hydrograph model for urban or other basins that gene...

Chemical and isotope based hydrograph separation methods, such as end member mixing analysis (EMMA), have been utilized in recent decades because they offer a better explanation of stream chemistry than can be obtained from flow partitions derived using graphical or mathematical filter hydrograph partitioning techniques (Chapman and Maxwell, 1996; Pinder and Jones, 1969). However, use of such c...

Increasing the use of water and soil resources in watershed in recent years and unproductive and inappropriate use of land ecology has exacerbated the occurrence of floods. In this context, watershed management is one of the most effective ways to cope with this crisis. This research quantify the results of these activities by calculating the decreased volume and discharge due to biomechanical ...
