“…In both cases, the fact that the sediment source was local (i.e., badlands) and accurately assessed helped to identify the delayed routing processes. This delay in sediment transfer linked to deposition and subsequent uptake is not represented in STREAM, a design choice that is lacking in many models and would deserve conceptual improvements in route modelling (Parsons et al, 2006;Kirkby, 2010). The connectivity concept, which includes a conceptual quantification of this parameter based on the combination of topography and land cover properties (Borselli et al, 2008), was introduced to tackle this problem (Cammeraat, 2004;De Vente et al, 2006).…”

“…Runoff and erosion responses can vary greatly at different scales. This variability may be due to the spatial variability of erosion parameters within the watershed and/or to the emergence of new water and sediment production and transfer processes, which occur when moving from a homogeneous hydrological unit to a heterogeneous watershed (Imeson and Lavee, 1998;Parsons et al, 2006;Canton et al, 2011).…”

International audienceThe objective of this study was to simulate the evolution of soil erosion in a semi-arid mountainouswatershed (225 km2, High Atlas Mountains, Morocco) under different scenarios of climate and land usechange to the end of 21st century. Erosion plots monitored over four years showed spatially contrastedresults. Most of the soils produced from 0.015 to 2.5 t/ha/y, whereas badlands produced350 t/ha/y The average sediment yield measured at the outlet during the same period wasapproximately 4 t/ha/y.The STREAM distributed erosion model was parameterized using these field measurements (infiltrationrates and runoff sediment concentrations). The results showed an overall agreement between themodelled and measured annual cumulative sediment yields.Simulations of the ARPEGE meteorological model were used for the 1960-1990 and 2070-2100 periods.The changes between these two periods were downscaled using three different methods,decreasing annual precipitations by 10-14%, although with more rainfall in summer and fall. Climatechange alone increased sediment yield by 4.7-10.1%. However, simulations showed that land usechanges might potentially induce much larger changes in erosion (up to 250%), approximately proportionalto the evolution of the extension of badlands

“…Mikesell 1960;Ajbiloua et al 2006;Esteban et al 2010). Moreover, the Moroccan landscape is subject to land degradation, desertification and ecosystem degradation (Barbero et al 1990;Messerli and Winiger 1992;Puigdefábregas and Mendizabal 1998;Parish and Funnell 1999;Sobrino and Raissouni 2000;McGregor et al 2009). Morocco has a number of protected terrestrial areas that are divided under several designations; National Park (11), Biological Reserve (5), Nature Reserve (13), Reserve (4), Natural Park (2), Botanical Park (1) and Forest Sanctuary (1) (World Database of Protected Areas [WDPA] Consortium 2009 version).…”

“…Earth's mean surface temperature has increased by approximately 1 °C since the beginning of the 20th century [3], and the temperature has increased by 0.4-0.5 °C from 1860 to 2005, most drastically after 1951, in China [4]. Through increases in temperature are coupled with changes in precipitation regimes, mountain regions seem to be particularly sensitive to the changing climate [5,6]. Due to their sensitivity to temperature and precipitation, mountain glaciers and snow covers have lost a considerable amount of their area and volume [7,8], and a further rise in temperature will exacerbate this situation [9].…”

Abstract:The melting of alpine snow and glaciers is an important hydrologic process on Mount Gongga, China. The relevance of ice-snow melt to the groundwater recharge in the glacierized Hailuogou watershed is so far not well known. To better understand the origin of groundwater and the hydrological interactions between groundwater, meltwater, and precipitation in this region, 148 environmental isotopic data of water samples were analyzed for changes in isotopic composition. The results indicate that the groundwater contains a uniform isotopic signature, with δ 18O values between −13.5‰ and −11.1‰ and δ 2 H values between −90‰ and −75‰. The mean stable isotopic composition of groundwater is heavier than that of ice-snow meltwater but lighter than that of precipitation. The effect of evaporation on the isotopic variation of groundwater is very limited and the seasonal isotope variations in precipitation are attenuated in groundwater. A model based on the δ 18O results suggests that approximately 35% of the groundwater is derived from ice-snow meltwater sources. The study demonstrates that ice-snow meltwater is a substantial source of shallow groundwater in the alpine regions on the edge of the Tibetan Plateau.
