Rivers has long been regarded as one of the most basic human water supplies. If the topography, a morphology, water requirements conditions, etc. allow water to be transferred to gravity, the use of the dike can have a significant impact on the flow rate and the sediment input to Intake. Dike design needs to consider several parameters such as position, length, type, etc. Using a good design ca...
this study was undertaken to investigate the effect of socioeconomic factors on fish catch around the lower ogun river in isheri-olofin area (downstream) and ishasi (upstream). two hundred and fifty (250) respondents were randomly sampled. the data was analyzed using descriptive statistics and chisquare. it was found that a large percentage (74.4%) owned personal fishing craft.18% of the respon...
Supply chain management (SCM) aims to efficiently integrate suppliers, manufacturers, warehouses, and retailers, not merely to ensure that merchandise is produced and distributed in the appropriate quantities, to the right locations, and at the right time, but also to minimize system wide costs while satisfying customer requirements. With global transnational enterprise layout trend, data consi...

One of the simple methods for erosion control, flood mitigation and flood damage reduction in the streams is building the check-dams. The present study was carried out to evaluate the performance of check-dams, location across the streams in the retention of the fine sediments in Dam-tang watershed in Darab Iran. For this purpose, two of streams with many stabilized check-dams which were more t...
The potential of artificial neural network models for simulating the hydrologic behaviour of catchments is presented in this paper. The main purpose is the modeling of river flow in a multi-gauging station catchment and real time prediction of peak flow downstream. The study area covers the Upper Derwent River catchment located in River Trent basin. The river flow has been predicted (at Whatsta...
Understanding how environmental gradients shape the spatial patterns of intraspecific genetic diversity is a central issue in ecological and evolutionary sciences. In riverine ecosystems, there generally an increase neutral downstream, as well differentiation among upstream populations. However, selective pressures may vary markedly along upstream–downstream gradient, which could modify these p...
Background and Objective: With the industrialization of communities, population increase and use of surface water, river pollution has been increased by agricultural, industrial pollutants and urban wastewater. Therefore, investigation of river pollution for regional and environmental planning is of great importance. To evaluate surface water pollution, a number of surface water quality indices...
This chapter examines the tradeoffs of regulating upstream (e.g., coal, natural gas, and refined petroleum product producers) versus regulating downstream (e.g., direct sources of greenhouse gases (GHG)). In general, regulating at the source provides polluters with incentives to choose among more opportunities to abate pollution. This chapter develops a simple theoretical model that shows why t...
