“…Several predominant parameters like weather condition, topographic characteristic, soil properties, and land use land cover (LULC) were required for successful set-up and run the SWAT model on a monthly time-scale (1.1.2010-31.12.2015) using the ArcSWAT interface (Neitsch et al, 2011;Markhi et al, 2019). Database of slope, soil and LULC distribution map over the thirty-eight sub-basins including 12,387 HRUs are presented in Fig.…”

“…Sensitive analysis of SWAT parameters must be needed for the determination of significant contribution on model outputs that are measured by ranking method (Holvoet et al, 2005;Markhi et al, 2019). In this context, SUFI-2 (sequential uncertainty fitting approach) is used for large calibration performance with the presence of minimum number of iterations and high calibration capacity (Yang et al, 2008).…”

“…According to Neitsch et al 2011, SWAT manual provided such default values that are fixed at every parameter range. In this research, ten parameters were considered for monthly flow discharge simulation, and ten parameters were considered for sediment load simulation at monthly timescale accurately based on literature review on these parameters in similar hydrological characteristics in drainage basin (Bokan, 2015;Mittal et al, 2016;Welde, 2016;Romagnoli et al, 2017;Asl-Rousta and Mousavi, 2019;Sridhar et al, 2018;Himanshu et al, 2019;Markhi et al, 2019). Based on sensitive analysis, best sensitive parameters are selected for the analysis of calibration and validation performance in SWAT model using p-value (Mittal et al, 2016).…”

“…The last version of the model, applied here, is the one proposed by Gavrilović [13] in 1988. Several authors have applied the method, especially in non-instrumented basins in the Mediterranean area [2,[14][15][16][17][18][19][20][21][22]. Nevertheless, a comparison with the PSIAC method [23,24] showed the same pattern for the predicted sediment yield, with a correlation coefficient of 0.95; it confirms the applicability of the EPM method for semi-arid and arid catchments [25,26].…”

Sediment Supply and Hydrogeological Hazard in the Quebrada de Humahuaca (Province of Jujuy, Northwestern Argentina)—Rio Huasamayo and Tilcara Area

et al. 2019

This paper describes the hydrogeological hazard in a reach of Quebrada de Humahuaca, (Upper Valley of Rio Grande de Jujuy, in the Argentine Andes), elected a World Heritage Site by UNESCO in 2003. Along the Quebrada, the Rio Huasamayo, flowing into the Rio Grande, formed a large alluvial fan where the village of Tilcara was built. The final reach of Rio Huasamayo is an artificial channel, embanked by unconsolidated material removed from the riverbed. The village is located in an area at a lower elevation with respect to the riverbed, still in aggradation; so it is affected by an evident hydrogeological hazard. The main cause of the riverbed aggradation is the enormous sediment supply from the slopes of the Rio Huasamayo basin. The aim of the paper is to estimate the soil loss on the slopes and the consequent sediment supply to the main stream, identifying the areas of the basin mostly affected by erosion processes that cause the aggradation of the Rio Huasamayo riverbed. In this case, due to the lack of hydrometeorological stations (monitoring rainfalls, temperature, flow rates, etc.), soil loss and sediment supply to the main stream cannot be estimated through the application of commonly used models in the literature (e.g., USLE, RUSLE, USPED). Here the Gavrilovic method (EPM) was applied in combination with the data of the CORINE Project, allowing the estimation of the volume of material exiting from the catchment. So the main supplying areas (sub-basins of the Rio Huasamayo) can be identified where focused interventions for the control of solid transport could be realized, to mitigate the process of riverbed aggradation.

A major problem facing the water sector in Algeria is deteriorating water quality, which is strongly influenced by nutrient inputs to agricultural watersheds. To mitigate the effects of agricultural activities and enhance water quality, this study considered the impact of different best management practices (BMPs) in agriculture. The objective of the research was to evaluate the impacts of various agricultural BMPs on nitrate losses in the Sebdou catchment in north-west Africa using the Soil and Water Assessment Tool (SWAT) model in order to identify and recommend the most appropriate BMP. The study was carried out in two parts: first, the SWAT model was calibrated and validated to simulate discharge and nitrate losses at the outlet of the catchment, and second, the calibrated model was used to assess the effects of BMPs on nitrate losses. The hydrological modelling fitted well with the observed data for the calibration and validation periods (NSE between 0.63 and 0.65 and R 2 between 0.80 and 0.92). Nitrate simulation was also satisfactory (NSE = 0.58 and R 2 = 0.58), with the average nitrate exports at the outlet varying between 136 and 149 t N year À1 . Agricultural tillage practices were the main N input and plant uptake was the main N output. The simulation results of BMP scenarios (contour farming, strip cropping and terracing) showed a significant decrease in nitrate quantity in soil, nitrate yield in surface run-off and nitrate exports. The maximum reduction was observed from the use of parallel terraces, which reduced nitrate in soil by 17% (41 kg ha À1 ) and decreased nitrate flux exportation to below 133 t N year À1 (a reduction of about 11%). This study provided useful information for implementation of the most effective agricultural BMPs in the catchment for stakeholders who are interested in soil and water management.
