    Abstract: In planning and management of any water resource systems prediction or estimation of runoff over the catchment is considered as a crucial factor. Many researchers over the past two decades addressed these problems by traditional methods as well as with some new techniques. This paper is describable and is focused on the capability of some data driv... Show More

    Abstract: Dissolved oxygen (DO) is a key water quality parameter and dynamic change prediction of water quality can provide a necessary assistance to solve the marine pollution problem. In this study, DO concentration data were collected from the buoy near Aoshan Island, Zhoushan, China. Based on DO concentration analysis, three prediction model were establi... Show More
  • Vertical Water Velocity Distribution Using Fine Different Sediment Concentrations in Circular Open Channel

    Abstract: The effect of fine different sediment concentrations on velocity distribution in open circular pipe was experimentally studied. An "ADV"(Acoustic Doppler Velocimeter) instrument was used for measuring the velocity distribution at the centerline of channel. Three different sediment concentrations of 1000 gm, 1500 gm and 2000 gm were added to the inp... Show More

    Abstract: In the sahelian coastal areas, most lowlands are threatened nowadays by the risk of salinization due to climate change. Given the scale of this soil’s degradation, several actions have been undertaken including anti-salt dam. Therefore, the objective of this work was to understand the impact of these dams on the fluctuation of ground water during w... Show More
  • Dam Break Analysis Using HEC-RAS and HEC-GeoRAS – A Case Study of Ajwa Reservoir

    Abstract: The paper initially describes about the details of the Ajwa Dam and further about the scenario of breaking of Ajwa Dam. The Ajwa Reservoir is located 20 km north-east of Vadodara city with waste weir and outlet works. The major reason of Vadodara being flooded in heavy rains is due to the release of water from Ajwa Reservoir. The attempt is made to... Show More

    Abstract: In the present research, the effect rough corrugated bed channels on the sediment transport and of the flow passes is studied. Hypothetically, four scenarios of bed cases are tested. In the first case, using large eddy simulation, LES, an investigation of smooth bed is performed for ReT equals 395 (number of Reynolds calculated using the mean frict... Show More
