Evaluation of Land use to Critican Batang Kuranji Watershed in Padang City
Abstract
This study aims to 1). find out the land use index 2). analyze the suitability of land \nuse based on land capability, 3). How is the spread and extent of critical watersheds 4). \ncalculate the level of erosion hazard in the Padang City Kuranji Watershed. This research uses \nquantitative descriptive method. Quantitative analysis is done by classifying, scoring, and \nweighting with existing scales and criteria. Samples are taken based on land units obtained \nfrom overlapping maps of landform units, slopes, land use, land and geology. The results \nshowed 1). there are three classes of land use index, namely good class 11,375 km2 (97.23%), \nmedium class 37.50 km2 (43.91%) and bad class 214.22km2 (16.71%). 2). suitability of land \nuse consists of two classes, namely: Appropriate class 19,099 km2 (85.97%) and class not \nappropriate 3.13 km2 (14.3%). 3) there are three classes to watershed criterion namely \nuncritical class (70.94%), critical potential class (24.54%) and critical class (4.53). 4). erosion \ndanger level there are five classes: Very light (68.64%), Lightweight class (9.75%), Moderate \nclass (14.68%), Weight class (4.79%) and Very Heavy class (2, 14%).
