River Bathymetry(河流测深)研究综述
River Bathymetry 河流测深 - In this study, a method was developed for the baseline characterization of river bathymetry and time-varying heights using globally available datasets from the Shuttle Radar Topography Miss. [1] USGS previously demonstrated that helicopter-mounted ground-penetrating radar (GPR) was useful for noncontact measurement of river bathymetry; however, the cost and complexity of low-altitude heliborne GPR precluded routine application of the method. [2] Therefore, it is very important to know the function of hydraulic structures over the river bathymetry and resultant sediment flow, transportation, and sediment deposition in this region. [3] Data related to surface elevation, river bathymetry, precipitation, temperature, and soil moisture data are used for different areas in the United States. [4] Fluvial remote sensing has been used to monitor diverse riverine properties through processes such as river bathymetry and visual detection of suspended sediment, algal blooms, and bed materials more efficiently than laborious and expensive in-situ measurements. [5] This study aimed to identify an optimal spatial interpolation for mapping the river bathymetry from cross-sectional sounding measurements. [6] The detailed geometry of the river bathymetry, islands, and hydraulic structures were incorporated in the numerical simulation using the curvilinear immersed boundary approach. [7] This study determines the aspects of river bathymetry that have the greatest influence on the predictive biases when simulating hyporheic exchange. [8] In this study, a physical model experiment with a geometric similarity of the bridge embankments, abutments, and bridge deck as well as river bathymetry was conducted in a laboratory flume. [9] River bathymetry, which is vital for accurate hydraulic modeling, is not readily available at large scales because of the logistical difficulties in field surveys and uncertainties associated with remote sensing techniques. [10] Moreover, no prior knowledge of river bathymetry is necessary. [11]在这项研究中，开发了一种方法，用于使用来自 Shuttle Radar Topography Miss 的全球可用数据集对河流测深和随时间变化的高度进行基线表征。 [1] 美国地质调查局此前证明，直升机安装的探地雷达 (GPR) 可用于河流测深的非接触式测量；然而，低空直升机 GPR 的成本和复杂性阻碍了该方法的常规应用。 [2] 因此，了解水工建筑物在河流测深上的作用以及由此产生的泥沙流动、运输和泥沙沉积在该地区是非常重要的。 [3] 数据 与地表高程、河流测深、降水、温度和 土壤湿度数据用于美国不同地区。 [4] 与费力和昂贵的原位测量相比，河流遥感已被用于通过河流测深和视觉检测悬浮沉积物、藻华和河床材料等过程来监测各种河流特性。 [5] 本研究旨在确定从横截面测深测量中绘制河流测深图的最佳空间插值。 [6] 使用曲线浸没边界法将河流测深、岛屿和水工结构的详细几何形状纳入数值模拟中。 [7] 本研究确定了在模拟低流交换时对预测偏差影响最大的河流测深方面。 [8] 在这项研究中，在实验室水槽中进行了具有几何相似性的桥堤、桥台和桥面以及河流水深测量的物理模型实验。 [9] 由于实地调查的后勤困难和与遥感技术相关的不确定性，河流测深对于准确的水力建模至关重要，但在大尺度上并不容易获得。 [10] 此外，无需事先了解河流测深知识。 [11]
