Erosion Intensity

This paper analyses the state of erosion intensity in the Vlasina River Basin, the right tributary of the Juzna Morava River. To determine the erosion intensity (Z) and sediment production, the Gavrilovic method was used, in combination with the bare-soil index (BSI), with the application of geographic information systems (GIS) and multispectral satellite imagery. An erosion coefficient of 0.31 has been identified in the territory of the Vlasina River Basin, which has an area of 1,061.72 km?. The prominent vertical fragmentation of the relief, large amount of precipitation in the source parts, density of the river network (1.65 km/km2), which is above the average river network density in Serbia, as well as inadequate land exploitation, are the main reasons why it is necessary to monitor the erosion intensity in the Vlasina River Basin. The annual production of the sediment is 462,496.30 m?, while the value of specific sediment production is 435,47 m?/km?/year. This study represents the attempt to apply modern technologies to d1etermine the intensity of erosion in the Vlasina River Basin, and the results obtained could be used for more adequate management of land and water resources, sustainable planning of the forest ecosystems and environmental protection.

Sediment Data

Very few data are available on the sediment yield of Alberta watersheds especially in the northern portion of the province. In the 175 000 km2 Peace River basin, which covers about 25% of Alberta, sediment data are collected regularly at only four stations. One of these is the 112.7 km2 Spring Creek watershed. In 1977 a pipeline was installed near the mouth of Spring Creek, disturbing an area of about 5000 m2 near the stream channel. The effects of this were to increase local sediment yields by over 1600 Mg in a 4 month period. This compares with regional averages for the Peace River basin of 18–88 Mg∙km−2∙year−1. The study indicates the magnitude of spatial variation of sediment production and shows some effects of geotechnical activities on sediment yields.

Basin Area

Seunagan River Basin Area has a very important role as a water needs for the people in Nagan Raya Regency and the half of West Aceh Regency. The condition of Krueng Seunagan River Basin Area is getting more and more critical which is marked by a lot of dangerous activities inside and outside the River Basin Area such as mining, land conversion and so on. This study aim are for knowing how much a yearly sediment production that happened in Krueng Seunagan River Basin Area and the Sediment Delivery Ratio (SDR) and also to recommend the effort of land  conservation. From the sediment rate analysis in Sub River Basin Areas, it obtained variation sediment rate that spread over 4 Sub River Basin Areas. From the yearly sediment production analysis result can be confirmed that the largest sediment production happened in Seunagan Hulu Sub River Basin Area, which the sediment production is 143.879,08 ton/year and then followed by Seunagan Hilir Sub River Basin Area 135.644,02 ton/year, and then Cut Sub River Basin Area 116.016,74 ton/year and the smallest sediment production happened in Isep Sub River Basin Area which the sediment production is 107.985,52 ton/year. The Sediment Delivery Ratio (SDR) result for each sub river basin area is Seunagan Hulu 9,6%, Isep 12,2 %, Cut 11,8% and Seunagan Hilir 10,0 %
