In Ethiopia's Upper Blue Nile Basin, soil erosion, land degradation, sedimentation of reservoirs, shortening the useful lives infrastructure, & lakes and loss agricultural soils are serious issues. The capacity to estimate yield sediment in Ribb Kessie watersheds is investigated using parameter-efficient semi-distributed watershed model water assessment tool. This study's goal was assess predic...

Common streamflow gauging procedures require assumptions about the stage-discharge relationship (the ‘rating curve’) that can introduce considerable uncertainties in streamflow records. These rating uncertainties are not usually considered fully in hydrological model calibration and evaluation yet can have potentially important impacts. We analysed streamflow gauge data and conducted two modell...

BACKGROUND To evaluate the feasibility of flexible ureteroscopy training by using isolated porcine kidneys and ureters in vitro. METHODS Twenty young urologists were randomly divided into four groups. Overall performance was assessed based on a global rating scale, pass/fail rating, total time to complete task, learning curve, incidence of trauma, and perforations. The effect of training was ...

Both water balance (WB) and rating curve (RC) are methods for estimating streamflow. The first is mostly used to estimate reservoir outflows, while the second usually adopted in hydrometeorological network streamflow gauges. While WB uses hourly collected data, RC estimates using current level extrapolation techniques. objective of this study was analyze variations reservoir’s outflow at Queima...

Previous studies have shown that listeners' perceptions of tones within a musical context are influenced by a hierarchy of tonal functions. This study investigated the influence of this hierarchy on the perception of microtones finer than the chromatic tones. Following the probe tone method introduced by Krumhansl and Shepard (1979), listeners rated each of the 48 eighth tones that occur within...

Reliable estimation of discharge in a river is the crucial component of efficient flood management and surface water planning. Hydrologists use historical data to establish a relationship between water level and discharge, which is known as a rating curve. Once a relationship is established it can be used for predicting discharge from future measurements of water level only. Successful applicat...

Managing stage-discharge relations at hydrometric stations affected by seasonal aquatic vegetation is challenging. Their ratings vary continuously in time so that establishing the streamflow series difficult. To best of our knowledge, no rating curve model exists to deal with a vegetated channel control, only manual adjustment methods. address this issue, temporal accounting for transient chang...
