Floodgate - an overview | ScienceDirect Topics The earlier use of floodgates that had been vetoed by the EA in Teignmouth, was subsequently put forward to remove similar objections from local businesses and waterside residents This involved a “hand-stitched” approach to fitting flood defense measures into the intricate and historic urban fabric rather than creating a new linear defense
Exploring the effect of floodgates operation systems on water . . . For the floodgates operation systems, preventing floods and droughts in a river network for protecting human society based on the safety of the water environment is a challenge However, researches that focused on the linkage between floodgates operation and water environmental capacity (WEC) is limited
Exploring the effect of floodgates operation systems on water . . . Moreover, the hydrodynamic conditions of the river network under with floodgates scenario were significantly worse than those under without floodgates scenario (There are more red squares in Fig 5-a and Fig 5-c than those in Fig 5-b and Fig 5-d) Thus, as the constant fields of pollutant loads, changes in the concentration response fields
Impact of floodgates operation on water environment using one . . . Floodgates operation is one of the major forms of river regulation in basin development and utilization, and have changed natural structures, processes of running water and associated environments However, there are few analysis on the impacts of multiple floodgates integration on water environment

Floodgates operation is one of the major forms of river regulation in basin development and utilization, and have changed natural structures, processes of running water and associated environments However, there are few analysis on the impacts of multiple floodgates integration on water environment
Optimal floodgate operation for river flood management: The case study . . . Thanks to the joint operation of the Regolatore and the Scaricatore facilities, water levels upstream of the VCS can be modified (to some extent, and compatibly with levee elevations) also for fixed flow rate values This gives additional flexibility to the entire control system if compared with the case of lateral floodgates only
Effects of floodgates operation on nitrogen transformation in a lake . . . Floodgates operation not only changes nutrient conditions (C, N and P) and water qualities but also influences microbial community composition (Feng et al , 2016) However, a comprehensive understanding of how floodgates operation, microbial communities and environmental factors interact to influence N transformation is lacking in lake ecosystems
Effects of floodgates operation on nitrogen transformation in a lake . . . Floodgates operation is one of the primary means of flood control in lake development However, knowledge on the linkages between floodgates operation and nitrogen transformation during the flood season is limited In this study, water samples from six sampling sites along Lake Xingkai watershed were collected before and after floodgates operation
Opening floodgates in coastal floodplain drains: effects on tidal . . . Floodgates were opened for total of 57 days over a 71-day period allowing tidal water into the transition drain Groundwater levels were monitored from about three weeks prior to the first opening Tidal forcing was evident in groundwater up to 10 m from the drain before the floodgates were opened ( Fig 6 a ), though the closest possible tidal
