From the viewpoint of river engineering, ecological rehabilitation means the restoration of channel configuration, riverbed profile, lost riparian vegetation, and wetland community.
基于河道治理的河流生态修复是指河道形态和河床断面的修复及恢复丧失的河岸带植被和湿地群落 ,可采用的具体方法有 :恢复河道的连续性 ;重现水体流动多样性 ;给河流更多的空间 ;慎重选择河道整治方案 。
To predict the water line with these models,the BAM neural network are used for the pattern recognition of riverbed profile.
针对现行的中小桥水害预测方法野外作业量大、缺乏资料无法预测等弊端,从推理公式出发,把实际中小桥河床断面分为9种类型,建立了各类断面直接从雨量到水位的水害预测模型;利用BAM神经网络对河床断面进行模式识别,以确定水害预测模型的类型;将该桥雨量—水位数据代入相应的水害预测模型,求解其中的参数,得出该桥的雨量—水位函数关系式。
