The Haw River, a high order river in the southeastern United States, is characterized by severe bank erosion and geomorphic change from historical conditions of clear waters and connected floodplains. In 2014 it was named one of the 10 most threatened rivers in the United States by American Rivers. Like many developed areas, the region has a history of disturbance including extensive upland soi...

With the re-evaluation and revision of a number of design floods, several embankment overtopping protection systems have been developed and a common technique is the construction of a stepped spillway on the downstream slope. For such moderate slope stepped channels, detailed air–water flow measurements were performed in a large facility with a focus on the rate of energy dissipation, flow resi...

a fish species prefer a particular habitat where provides its biological requirements, hence, understanding their habitat use and preferences are crucial for their effective management and protection. this study was conducted to assess the habitat use and selection patterns of alburnoides namaki , an endemic fish in jajroud river, namak lake basin, iran. the river was sampled at 18 equally spac...

At present the large scale vegetation restoration and intensive oil exploiting had brought huge influence on local environment in Yan'an region. the sediment yield data form series experiment plots and hydrological monitoring station in the Yan'an watershed after one rainfall event on July 2, 2005, which included sediment from different land uses (crop-land plot, vegetation plots, hard road sur...

Although the current ecological engineering technology can reinforce shallow landslides, it cannot deep landslides. A new type of technology-living tree stump slope protection was developed, aiming at deficiency technology. For living stumps with different tap root lengths, mechanical properties and system were analyzed. The model based on finite element method, using Mohr-Coulomb failure crite...

FAN7340 is a single-channel boost controller that integrates an N-channel dimming MOSFET using Fairchild’s proprietary planar DMOS technology. The IC operates as a constant-current source for driving high-current LEDs. FAN7340 uses a current-mode control with programmable slope compensation to prevent sub-harmonic oscillation and provides protections such as Open-LED Protection (OLP) and Over-V...

two dimensional slope profile morphometric investigation in a part of the land failure prone garhwal region of the lesser himalaya, tehri district, u. p., india, indicates that the landslip morphology is closely related to the dominant movement processes active in this terrain. technique developed for the morphometric analysis of landslips involves the use of five morphometric indices. each ind...
