沿海内河船舶理赔公估实务的探讨

沿海内河船舶通常通航于湖泊、内河等地区,随着我国河运的发展,越来越多的内河船只进行内河与临海港口之间的物流运输,相关船舶质量问题频频出现。其中,内河船舶保险理赔作为专业综合性较高的工作,需要相关技术人员共同进行理赔公估讨论。目前沿海内陆船舶保险理赔公估受到了相关专家学者的重点关注,然而,仍旧存在不少问题。因此,文章首先结合沿海内河船舶保险理赔公估案件的特征,分析安全质量事故发生时公估人在保险理赔中所参与的工作的内涵,其次介绍了沿海内河船舶检验及安全检查的要点,以便为船舶保险理赔工作的开展提供理论参考依据。

Suspended sediment concentration mapping based on the MODIS satellite imagery in the East China inland, estuarine, and coastal waters

The purpose of this research is to improve the retrieval accuracy for the suspended sediment concentration(SSC) from in situ and satellite remote sensing measurements in turbid East China estuarine and coastal waters. For this aim, three important tasks are formulated and solved: 1) an estimation of remote-sensing reflectance spectra R_(rs)(λ) after atmospheric correction; 2) an estimation of R_(rs)(λ) from the radiometric signals above the air-water surface; and 3) an estimation of SSC from R_(rs)(λ). Six different models for radiometric R_(rs)(λ) determination and 28 models for SSC versus R_(rs)(λ) are analyzed based on the field observations made in the Changjiang River estuary and its adjacent coastal area. The SSC images based on the above-mentioned analysis are generated for the area.
