Explicit Functions for Implicit Reservoir Routing
نویسنده
چکیده
Reservoir routing is often conducted with the stage-storage curve of the storage facility. Often at a planning stage, little hydraulic information about the storage facility is known yet. Therefore, a performance curve such as the storage-outflow curve needs to be developed from hydrologic information without detail basin geometry and outlet hydraulics. This paper presents a hydrology based procedure by which the performance curve of a storage facility can be derived from the only knowledge of the inflow hydrograph and design release rate. The three routing functions derived in this study provide either direct graphic solutions or numerical solutions by iterations. It is a useful planning method for a regional flood control planning using detention facilities, water supply planning using a reservoir system, and scenario studies involving storage facilities.

A case study of flood dynamic wave simulation in natural waterways using numerical solution of unsteady flows
Flood routing has many applications in engineering projects and helps designers in understanding the flood flow characteristics in river flows. Floods are taken unsteady flows that vary by time and location. Equations governing unsteady flows in waterways are continuity and momentum equations which in case of one-dimensional flow the Saint-Venant hypothesis is considered. Dynamic wave model as ...

Despite the general findings that address the positive contribution of teaching pragmatic features to interlanguage pragmatic development, the question as to the most effective method is far from being resolved. Moreover, the potential of literature as a means of introducing learners into the social practices and norms of the target culture, which underlie the pragmatic competence, has not been...
متن کاملDirect and Indirect Timing Functions in Unilateral Hemispheric Lesions
Introduction: The neural substrates of temporal processing are not still fully known. The majority of interval timing studies have dealt with this subject in the context of “Explicit timing” (computing the time intervals explicitly). The hypothesis “Implicit timing” (implicitly using temporal processing to improve function) has also proposed. This lesion study addressed explicit and implicit ti...
متن کاملEvaluating the Effectiveness of Explicit and Implicit Form-Focused Instruction on Explicit and Implicit Knowledge of EFL Learners
Although explicit and implicit knowledge of language learners are essential to theoretical and pedagogical debates in second language acquisition (SLA), little research has addressed the effects of instructional interventions on the two knowledge types (R. Ellis, 2005).This study examined the relative effectiveness of explicit and implicit types of form-focused instruction (FFI) on the acquisit...
متن کاملMeasuring the Effectiveness of Explicit and Implicit Instruction through Explicit and Implicit Measures
Many studies have examined the effect of different approaches to teaching grammar including explicit and implicit instruction. However, research in this area is limited in a number of respects. One such limitation pertains to the issue of construct validity of the measures, i.e. the knowledge developed through implicit instruction has been measured through instruments which favor th...
