Abstract

The Achanakmar Tiger Reserve (ATR) is an integral part of the Achanakmar Amarkantak Biosphere Reserve (AABR) with a total area of 914.017 sq. km. The Maniyari River, which flows through the reserve, is known as its life line. It originates from the core zone (Sihawal sagar) of ATR and merges in the Seonath River of the Mahanadi Basin. It flows about 105 km through Mungeli and Bilaspur districts. This river supplies its catchment area with water seasonally (6-8 months) and flows more than half of its length (about 60 km) within the protected area. Its catchment area has a rich biodiversity of tree species such as Shorea robusta, Terminalia tomentosa, Diospyros melanoxylon, Adina cordifolia, Pterocarpus marsupium, Madhuca indica, Anogeissus latifolia, Dendrocalamus strictus etc. A geospatial analysis was performed to understand the course of the Maniyari River within the ATR area over a fourteen year period between 2000 and 2013. Imagery from Indian Remote Sensing (IRS) satellite 1D and P6 for years 2000, 2004, 2008, 2010 and 2013 and Survey of India toposheets were analyzed to examine the changes in planform characteristics of the Maniyari River. The meander shift of the river was delineated considering the R1 (11.61 km), R2 (11.19 km), R3 (5.33 km) and R4 (5.02 km) reach’s respectively. Sinuosity Index (SI) for different reaches was calculated and evaluated. The SI ranged from 1.40 to 1.63, 1.20 to 1.29, 1.17 to 1.37, and 1.20 to 1.49 in R1, R2, R3 and R4 respectively and the magnitude of the shift was analyzed with the year 2000 as the base year. The overall SI for all the reach’s ranges between 1.30 and 1.36. The present study will be helpful in understanding the river dynamics as well as to maintaining the flow of the Maniyari River and preventing bank line erosion. The study will be helpful for the conservation of river flow and its tributaries in the ATR area in Central India.

印度恰蒂斯加尔邦阿恰纳克马尔老虎保护区马尼亚里河的动态及其蜿蜒性质:地理空间分析

阿恰那克马尔老虎保护区(ATR)是阿恰那克马尔阿坎塔克生物圈保护区(AABR)的组成部分，总面积为914.017平方公里。公里。流经保护区的马尼亚里河(Maniyari River)被称为保护区的生命线。它起源于ATR核心带(Sihawal sagar)，并与Mahanadi盆地的Seonath河合并。它流经Mungeli和Bilaspur地区约105公里。这条河季节性地(6-8个月)向其集水区供水，在保护区内流量超过其长度的一半(约60公里)。其集水区有丰富的树种，如Shorea robusta、Terminalia tomentosa、Diospyros melanoxylon、Adina cordifolia、Pterocarpus marsupium、madhua indica、Anogeissus latifolia、Dendrocalamus strictus等。为了了解2000年至2013年14年间ATR区域内马尼亚里河的河道，进行了地理空间分析。利用2000年、2004年、2008年、2010年和2013年印度遥感(IRS) 1D和P6卫星影像以及印度地形调查(Survey of India toposheets)，分析了马尼雅里河地形特征的变化。以R1河段(11.61 km)、R2河段(11.19 km)、R3河段(5.33 km)和R4河段(5.02 km)为基准，圈定了河段的曲流位移。计算并评价了不同河段的曲度指数(SI)。R1、R2、R3和R4的SI分别为1.40 ~ 1.63、1.20 ~ 1.29、1.17 ~ 1.37和1.20 ~ 1.49，并以2000年为基准年分析其变化幅度。整体指数在1.30至1.36之间。本文的研究将有助于了解河流的动态，以及维持马尼雅里河的流量和防止河岸侵蚀。该研究将有助于印度中部ATR地区河流及其支流的保护。
