MONITORING EROSION AND ACCRETION SITUATION IN THE COASTAL ZONE AT KIEN GIANG PROVINCE
erosion/accretion Kien Giang province Normalized Difference Water Index (NDWI) shoreline
2018/5/8
Kien Giang is one of the coastal provinces in the Mekong Delta which is facing the problem of coastal erosion to affect people’s life in the coastal area. This project aims to monitor shoreline and to...

This study is focused on the historical evolution of a heavily eroded field with discontinuous grass cover on a major thalweg (ephemeral gully). Tens of parcels originally formed a protective pattern ...
液化玉米秸秆基固沙剂控制土壤风蚀试验（Experiment on Sandy Fixation Material Based on Liquefied Corn Stover to Decrease Wind Erosion）
玉米秸秆 液化 聚氨酯 土壤风蚀 固沙剂
2010/5/5
以室内风洞试验机为主要设备，研究了液化玉米秸秆及液化玉米秸秆基聚氨酯作为固沙剂对筑渣土的保护效应。研究结果表明，二者均能粘结土样表面的大小颗粒形成保护层，提高建筑渣土的抗风蚀性；当液化玉米秸秆的喷施量较低时，随着风速的提高，对土壤的保护作用逐渐消失，土壤的侵蚀度迅速增加；液化玉米秸秆基聚氨酯作为固沙剂的效果要明显优于液化玉米秸秆，当其喷施量为120.37g/m2时，起沙风速超过20m/s，当固沙效...
数字图像处理在SEM空蚀图像定量分析中的应用（Quantitative Analysis of Cavitation Erosion Based on Image Processing）
空蚀 翼型 图像处理 模糊增强
2009/8/11
针对收缩－扩散型水洞中进行铝制翼型空蚀破坏试验时，传统度量不能准确量化翼型表面不 同位置的空蚀程度，提出了数字图像检测的方法。获取试验翼型表面SEM空蚀图像,然后对图像进行模糊增强，并进行类间方差最大阈值分割，用二值形态学方法处理边缘，最后由统计特性计算出空蚀破坏表面积、蚀坑数量等。图像测量可得到空蚀对翼型表面破坏数值的定量结果。
