摘要

该研究利用遥感和地理信息系统技术确定了伊拉克迪亚拉省 Wadi Al-Naft 盆地的流域范围,并计算了各种形态特征。研究结果显示存在两个子流域,每个子流域有四条溪流。排水密度是衡量单位面积内溪流长度的指标,分别为 0.19 和 0.16 公里/平方公里。他们发现有 153 条溪流,根据大小和连通性分为不同等级。一阶溪流长 882.71 千米,共计 128 条,二阶溪流长 533.12 千米。三阶溪流有 4 条,总长度为 199.9 千米,四阶溪流有 2 条,总长度为 57 千米。这些结果可用于研究该地区的水流模式,对了解 Wadi Al-Naft 盆地的水文特征至关重要。为了有效管理水资源,这项研究强调了地理信息系统在获取水资源数据(包括一系列形态测量因素)方面的价值。作为水资源管理的宝贵工具,本文概述了确定和描述可用于案例研究的流域的系统过程。

Integrating remote sensing and GIS techniques for effective watershed management: a case study of Wadi Al-Naft Basins in Diyala Governorate, Iraq, using ALOS PALSAR digital elevation model

The study used remote sensing and GIS techniques for defining the watershed and computing various morphometric characteristics of the Wadi Al-Naft Basins in Diyala Governorate, Iraq. The findings reveal the existence of two sub-basins, each of which was found to have four streams order. The drainage density, a measure of the stream length per unit area, was found to be 0.19 and 0.16 km/km2, respectively. They found 153 streams, categorized into different orders based on size and connectivity. First-order streams were found to be 882.71 km in length, totalling 128, while second-order streams totalling 533.12 km in length. Third-order streams numbered 4 with a total length of 199.9 km, while there were two fourth-order streams with a total length of 57 km. These results may be utilised to examine water flow patterns in the area and are crucial for understanding the hydrological features of the Wadi Al-Naft Basin. To effectively manage water resources, the research underlines the value of GIS in obtaining data on water resources, including a range of morphometric factors. A valuable tool for water resource management, the paper outlines a systematic process for identifying and characterising watersheds that may be used in a case study.

期刊介绍: Applied Geomatics (AGMJ) is the official journal of SIFET the Italian Society of Photogrammetry and Topography and covers all aspects and information on scientific and technical advances in the geomatics sciences. The Journal publishes innovative contributions in geomatics applications ranging from the integration of instruments, methodologies and technologies and their use in the environmental sciences, engineering and other natural sciences. The areas of interest include many research fields such as: remote sensing, close range and videometric photogrammetry, image analysis, digital mapping, land and geographic information systems, geographic information science, integrated geodesy, spatial data analysis, heritage recording; network adjustment and numerical processes. Furthermore, Applied Geomatics is open to articles from all areas of deformation measurements and analysis, structural engineering, mechanical engineering and all trends in earth and planetary survey science and space technology. The Journal also contains notices of conferences and international workshops, industry news, and information on new products. It provides a useful forum for professional and academic scientists involved in geomatics science and technology.
