The process-based model needs to be calibrated before its applications to derive a reliable estimate. A process-based agricultural policy/environmental eXtender (APEX) model was utilised to assess surface runoff and soil loss of a micro-watershed belongs to the Shivalik region of Himachal Pradesh, India. The model was performed exceptionally well for surface runoff (r2 - 0.81) and sediment yield (r2 - 0.81) with the Nash- Sutcliffe Efficiency assessments of 0.71 for surface runoff and 0.70 for sediment yield. The average annual soil loss is 23.42 t ha-1yr-1 from the watershed. The study revealed that the soil erosion in the Shivalik region increases and identified scrubland as the significant source for generating soil erosion in the watershed. Also, the APEX model could predict surface runoff and soil loss in the Shivalik region. The comprehensive information generated from the study will help to generate a sustainable land use plan in the Shivalik region.
基于过程的模型需要在其应用之前进行校准，以得出可靠的估计。利用基于过程的农业政策/环境扩展器(APEX)模型评估了印度喜马偕尔邦Shivalik地区一个小流域的地表径流和土壤流失。该模型在地表径流(r2 - 0.81)和产沙量(r2 - 0.81)方面表现得特别好，地表径流的Nash- Sutcliffe效率评估为0.71，产沙量为0.70。流域年平均土壤流失量为23.42 t ha- 1year -1。研究表明，Shivalik地区的土壤侵蚀增加，并确定灌木丛是流域土壤侵蚀的重要来源。APEX模型还可以预测Shivalik地区的地表径流和土壤流失量。这项研究产生的综合信息将有助于在Shivalik地区制定可持续的土地利用计划。

The threshold of motion of commonly found sediments in streams and rivers, sand and gravel which are mainly siliceous in nature, has been studied thoroughly since the development of the field of sediment transport in fluvial hydraulics. There are other types of sediment, of more irregular shape, such as bioclastic, biogenic, and organic detritus which need a special focus vis-a-vis their transport. This study considers the incipient motion of such sediments and finding a better representation of their threshold of motion. This study considers the empirical curves of some previous researchers and the scatter of data from unconventional sediment to assess the threshold behaviour of such sediment under unidirectional flow. The consideration of the settling velocity in the sediment threshold studies is important in general and for the sediment studied here in particular. The Movability Number is found to be a better representation of the threshold than the Shields parameter or square of Movability Number as data show less scatter about empirical curves.

This paper aims to identify the mineralisation origin and distinguish between the different classes of groundwater quality in several regions of the semiarid basin of Hodna in central Algeria. Many multivariate statistical techniques are applied to a dataset composed of 64 georeferenced individuals with 19 chemical variables. The obtained results from this principal component analysis show that the first five factors explain more than 78% of the groundwater quality variance. Other methods such as CA cluster analysis, CAH hierarchical cluster analysis and geochemical analysis using the Piper diagram are more appropriate to contemplate nodule-facies development and to distinguish clusters. The endorheic characteristic of the study basin consequents the basin centre named Chott El Hodna to be a salinity source. Bit by bit, salinity raises from North to South, from unsalted water to strongly salted water close to the Chott. The outcomes demonstrate that this groundwater is portrayed, the facies definite assessment outlines that the chloride, calcium and magnesium sulphate facies indicate 84% of cases, trailed by sodium sulphate facies with 14% and the rest (2%) is identified by the bicarbonate facies.
本文的目的是确定矿化起源和区分不同类别的地下水质量在阿尔及利亚中部的半干旱盆地的几个地区。许多多元统计技术应用于由64个地理参考个体组成的数据集，其中包含19个化学变量。主成分分析结果表明，前5个因子解释了78%以上的地下水水质变异。其他方法，如CA聚类分析、CAH分层聚类分析和使用Piper图的地球化学分析，更适合考虑结核相发育和区分聚类。研究盆地的内源性特征决定了该盆地中心(Chott El Hodna)是一个盐度源。盐分从北到南逐渐升高，从无咸水到靠近乔特河的高咸水。结果表明，该地区的地下水是被描绘出来的，相确定评价表明，氯化钙、硫酸镁相占84%，其次是硫酸钠相，占14%，其余为碳酸氢盐相(2%)。
