Windows Dam Analysis Modules (WinDAM) is a set of modular software components that can be used to analyze overtopped earthen embankments and internal erosion of dams. WinDAM is being developed in stages. The initial computational modules address routing of floods through the reservoir with dam overtopping and evaluation of the potential for vegetation or riprap to delay or prevent failure of th...

the reliable operation of spillways, in emergency as well as normal conditions, is one of the vital components in dam safety. free or uncontrolled overflow spillways are the most reliable choice however. they usually impose higher construction cost and /or results in wasting a considerable amount of water or live capacity of the reservoirs. employing fuse gates might be a way of reconciling dam...

BACKGROUND Stepped wedge randomised trial designs involve sequential roll-out of an intervention to participants (individuals or clusters) over a number of time periods. By the end of the study, all participants will have received the intervention, although the order in which participants receive the intervention is determined at random. The design is particularly relevant where it is predicted...

As the size of quartz resonator continues to shrink, beveling of the plano-plano quartz crystal is needed to reduce mounting loss and to sustain energy trapping so to have low motional resistance for oscillation. The beveling process though is time consuming and difficult to control for small size and low frequency quartz crystals. In recent years, studies on stepped electrode (a.k.a bi-mesa el...

BACKGROUND Revised guidelines for depression recommend a stepped care approach. Little is known about the implementation of the stepped care model by general practitioners (GPs) in daily practice. OBJECTIVES To evaluate the performance of Dutch GPs in their general practice regarding important elements of the stepped care model (identification, severity assessment and stepped care treatment a...

labyrinth spillway is an appropriate option to pass pmf discharge. the most advantages of this type of spillway are higher discharge capacity, easy aeration as well as low fluctuations of flow surface. it is essential to find the optimum geometry considering the maximum passing discharge under specific hydraulic conditions with minimum construction cost. in this study, fuzzy inference system (f...

Stepped care is an increasingly popular treatment model for common mental health disorders, given the large discrepancy between the demand and supply of healthcare service available. In this review, we aim to compare the efficacy and cost-effectiveness of stepped care prevention and treatment with care-as-usual (CAU) or waiting-list control for depressive and/or anxiety disorders. 5 databases w...

Abstract: Control of reservoir sedimentation in order to ensure their sustainable use has drawn attention among water engineers and water resource managers. Several methods have been proposed, but most of the developed methodologies are incapable of modelling bed evolutions, while at the same time, compute sediment flushing efficiency. In this study a two-dimensional bed evolution model is prop...
