Abstract. The bank-full depths, widths, depth-averaged water velocities, and along-channel slopes of alluvial channels are approximately power-law functions discharge across many orders magnitude. What mechanisms give rise to these patterns is one the central questions fluvial geomorphology. Here it proposed that depths partially controlled by maximum heights gravitationally stable channel bank...

Access to an adequate supply of nutritious food has been recognized as a basic human right. However, many families across the UK face food insecurity, which is thought to be exacerbated during school holidays. To address this issue, some schools and community groups have chosen to roll out holiday clubs, though research into the effectiveness of such interventions is limited and no studies to d...

Uncertainty analysis (UA) has received substantial attention in water resources during the last decade. Bayesian approaches are often preferred for UA. This study describes a formal Bayesian approach for the assessment of parameter uncertainty and predictive uncertainty using a spatially distributed hydrologic model and will demonstrate its application using data from a well monitored experimen...

Monitoring the water contaminants is of utmost importance in resource management. Prediction total dissolved solid (TDS) particularly essential for quality management and planning areas exposed to a mixture pollutants. TDS primarily includes inorganic minerals organic matters, various salts increasing concentration causes esthetic problems. The reflection pollutant burden aquatic system can rem...

A new methodology was developed for the real-time determination gate control operations of a river-reservoir system to minimize flooding conditions. The is based upon an optimization-simulation model approach interfacing genetic algorithm within MATLAB with simulation software short-term rainfall forecasting, rainfall–runoff modeling (HEC-HMS), and one-dimensional (1D), two-dimensional (2D), co...

Picture reranking is helpful for adjusting the presentation of content base picture seeks. In any case, reachable reranking estimations are compelled for two essential drivers: 1) the printed meta-data related with pictures is every now and again opposite with their real picture substance and 2) the uprooted visual highlights don't decisively demonstrate the semantic resemblances among pic...

r Publis .028 .: +1 412 @usgs.go Summary Forecasting streamflow during extreme hydrologic events such as floods can be problematic. This is particularly true when flow is unsteady, and river forecasts rely on models that require uniform-flow rating curves to route water from one forecast point to another. As a result, alternative methods for measuring streamflow are needed to properly route flo...

[1] We assess the spatial distribution of the largest rainfall-generated streamflows from a database of 35,663 flow records composed of the largest 10% of annual peak flows from each of 14,815 U.S. Geological Survey stream gaging stations in the United States and Puerto Rico. High unit discharges (peak discharge per unit contributing area) from basins with areas of 2.6 to 26,000 km (1–10,000 mi...

Although rainwater harvesting (RWH) is gaining popularity as a sustainable water supply source in urban as well as rural areas, estimating required storage remains an important design challenge. This paper develops a robust, yet computationally simple equation for calculating required storage capacity for a RWH system, which is generally applicable in the United States (U.S.). A simulation mode...

The research on engineering experiment is a key step in translating technical development to industrial application. Active, optical range imaging sensors collect three-dimensional coordinate data from object surfaces and can be useful in a wide variety of automation applications, including shape acquisition, bin picking, assembly, inspection, gaging, robot navigation, medical diagnosis, and ca...
