“…The continuous increase in anthropogenic activities can be simplified and represented as LU changes, enabling the application of comprehensive models and statistical methods [14][15][16]. Also, the impacts of LU changes on surface runoff at different spatial and temporal scales have been studied [17][18][19][20][21].…”

The relative contributions of different factors to the variation in surface runoff have been broadly quantified. However, little attention has been paid to how these relative contributions have changed over time. We analyzed the changes in surface runoff during 1980-2010 in six subbasins in the mountainous region of the Haihe River Basin, one of the most serious water shortage regions in China, and identified the changes in the relative contributions of climate (precipitation and temperature) and land-use to surface runoff decrease. There was a decreasing tendency in surface runoff in all subbasins, four of which had an abrupt change point around 1998. Comparing the relative contributions before and after 1998 in the four subbasins, the average influence of climate was found to decline dramatically from 67.1% to 30.5%, while that of land-use increased from 23.9% to 69.5% mainly due to the increase of forest area. Our results revealed that the primary environmental factor responsible for runoff variations was not constant, and an alternation may accentuate the impact and stimulate an abrupt change of runoff in semiarid and semihumid mountainous regions. This will help in taking tracking measures to deal with the complex water resource challenges according to different driving factors.

“…Documented literature reveals that often, several hydrological studies only deal with specific components of water balance, e.g., streamflow 14 15 16 , groundwater recharge 17 18 19 20 , runoff 21 22 23 24 and evapotranspiration 25 26 27 28 . Land use affects stream runoff 29 30 31 , water infiltration capacity 32 33 and surface evaporation 34 35 36 . However, few studies have focused on the evaluation of basin water balance in terms of the impact of LUCC and climate change on hydrological processes.…”

The contributions of climate and land use change (LUCC) to hydrological change in Heihe River Basin (HRB), Northwest China were quantified using detailed climatic, land use and hydrological data, along with the process-based SWAT (Soil and Water Assessment Tool) hydrological model. The results showed that for the 1980s, the changes in the basin hydrological change were due more to LUCC (74.5%) than to climate change (21.3%). While LUCC accounted for 60.7% of the changes in the basin hydrological change in the 1990s, climate change explained 57.3% of that change. For the 2000s, climate change contributed 57.7% to hydrological change in the HRB and LUCC contributed to the remaining 42.0%. Spatially, climate had the largest effect on the hydrology in the upstream region of HRB, contributing 55.8%, 61.0% and 92.7% in the 1980s, 1990s and 2000s, respectively. LUCC had the largest effect on the hydrology in the middle-stream region of HRB, contributing 92.3%, 79.4% and 92.8% in the 1980s, 1990s and 2000s, respectively. Interestingly, the contribution of LUCC to hydrological change in the upstream, middle-stream and downstream regions and the entire HRB declined continually over the past 30 years. This was the complete reverse (a sharp increase) of the contribution of climate change to hydrological change in HRB.

“…BFC2012 affects the basin draining the upper Marrecas River valley, main ly under the terms of item IX of the Article 4, wh ich deals with the classification rules of hilltop PPAs, and under the terms of the Article 61-A, wh ich authorizes, in PPAs, "to continue agrosilvopastoral, ecotourism, and rural tourism activit ies in rural areas consolidated until July 22, 2008". The anthropic use of these PPAs potentiates and increases flow peaks, increasing the frequency and severity of flooding (Costa et al, 2012;Kalantari et al, 2014;Sanyal et al, 2014;Algeet-Abarquero et al, 2015).…”

Implications for Peak Flows of the Marrecas River Basin Due to Changes in the Brazilian Forest Code

Changes in the Brazilian Forest Code (BFC) have soften the criteria for recovery and conservation of permanent preservation areas (PPAs), enhancing processes related to surface runoff. The aim of this study is to understand the effects of changes in PPA classification criteria established by BFC of 2012 to the detriment of BFC from 1965 considering the surface runoff response in the basin draining the upper Marrecas River valley in the flow peaks. The HEC-HMS model was used to simulate flow peaks considering three land-use scenarios, representative of the current use, adapting it to PPAs fitted to the BFC of 1965 and 2012 and seven precipitation return periods. In the proposed scenarios, the use of BFC of 2012, to the detriment of that from 1965, would imply a PPA reduction from 44.5% to 13.7%, resulting in a 22.1% increase in the average flow peaks, not representing, however, a significant reduction in the flow peaks when compared to the scenario representing the current land use. Therefore, when compared to BFC of 1965, in the Brazilian new Forest Code PPAs were reduced by 69.2%, increasing peak flows by up to 30.7%, thus minimizing the legal possibilities of flood mitigation to the urban perimeter of Francisco Beltrão, Paraná State, Brazil.
