Ecologically Based Methods for Multi-Objective Water Resources Management in Taiwan
… that considers physical habitat, spawning, ecological issues, water quality issues, and human values for Northern Taiwan. By using the matrix analysis method, fish community habitat requirements can be identified. The Taiwan Ecohydrology Index System (TEIS) has been developed by adding …

Minimizing the detrimental effects of hydro-peaking on riverbank instability: The lower Osage River case
… level downstream from dams due to hydropower flow releases negatively affects the riverbank stability. Therefore, this research aims to examine the feasibility of using an optimization technique to mitigate the riverbank instability resulting from the outflow variation of hydropower plants. …

Environmental Flow Determination in Headwater Catchments of Luvuvhu River in Limpopo Province, South Africa
… national water legislation officially integrates ecological flow allocation within its legal framework, yet implementation in data-scarce, ecologically sensitive headwaters remains uneven and/or underdeveloped. This study addresses the absence of defensible environmental flow requirements (EFRs) …

Variations of Wildlife Safety Crossings and Their Effects for Mule Deer in Northeast Nevada
… available to each individual declines and gene flow is decreased as populations become increasingly isolated (Bissonette and Adair 2007; Forman et al. 2003). Barriers can also reduce regional population numbers since suitable habitats and resources may become unavailable (Forman et al. 2003). …

Hidrogeología del sistema kárstico de La Fuentona de Muriel (Soria)
… year 2003-2004 La Fuentona had a volume of flow of 978 l/s, presenting a variability of 191%, that is to say, significant enough, with a curve of exhaustion of expression Qt = 137.376 * e -0,0096 and a hydrodynamic volume at the beginning of the emptying of 14,3 hm3. The calculated …
