“…Similarly, [50] reported that an increase in annual surface runoff increased when forest lands were converted to urban areas and decreased during when forestland gained a significant expansion. Maalim et al [51] [53] partly play a role.…”

The Soil and Water Assessment Tool (SWAT) is a versatile model presently used worldwide to evaluate water quality and hydrological concerns under varying land use and environmental conditions. In this study, SWAT was used to simulate streamflow and to estimate sediment yield and nutrients loss from the Murchison Bay catchment as a result of land use changes. The SWAT model was calibrated and validated for streamflow for extended periods. The Sequential Uncertainty Fitting (SUFI-2) global sensitivity method within SWAT Calibration and Uncertainty Procedures (SWAT-CUP) was used to identify the most sensitive streamflow parameters. The model satisfactorily simulated stream discharge from the catchment. The model performance was determined with different statistical methods. The results showed a satisfactory model streamflow simulation performance. The results of runoff and average upland sediment yield estimated from the catchment showed that, both have increased over the period of study. The increasing rate of runoff can lead to severe and frequent flooding, lower water quality and reduce crop yield in the catchment. Therefore, comprehensive water management steps should be taken to reduce surface runoff in the catchment. This is the first time the SWAT model has been used in the Murchison Bay catchment. The results showed that, if all uncertainties are minimised, a well calibrated SWAT model can generate reasonable hydrologic simulation results in relation to land use, which is useful to water and environmental resources managers and policy and decision makers.

“…Sànchez et al (2002) conducted an experiment in the Venezuelan Andes showed that erosion in -1 the natural forest was 0.43 mg ha , which was lower than -1 horticultural crops in rotation (22 mg ha ), apple tree (1.96 -1 -1 mg ha ), and pasture without grazing (1.11 mg ha ). Ngo et al (2015) reported that land use change in Da River Basin in Vietnam from forest to field crop and urban area increased annual runoff and sediment, while forest expansion conservation decreased runoff and sediment. Table 2 and Tabel 3 show soil moisture dynamic in the forest, agroforestry, and rainfed agriculture at upper, middle, and downstream for dry season (August to October 2014) and rainy season (November 2014−March 2015), and for two soil depths, namely 0−20 cm and 20−40 cm.…”

To determine the characteristics of runoff generation and soil erosion at the different ages of Acacia plantation in Luong Son headwater of Vietnam, four plots (15m 2 plot -1 ) were set up. Of those, two plots were at up-hill and down-hill in 1-year-old and two plots in 5-years-old Acacia plantation. Soil erosion and runoff were monitored during rainy season from April to September 2018. The main findings include: (1) Runoff coefficient at Acacia 1-year-old down and up ranged from 0.36% -0.46% with the average 0.41%. Acacia 5-years-old, down and up was 0.35% -0.39%, averaged 0.37%. It shows the slightly diffences between the locations of two years due to the different ground cover but not statistically significant different; (2). Soil erosion in Acacia-1 and Acacia-5 year old were 21.84 and 14.20 ton/ha/6months, respectively. The data for soil erosion was statistically significant different between two ages of Acacia plantation. Soil erosion at the study site was very high within strong erosion base on TCVN5299: 2009; (3) Both runoff and soil erosion had strong relationship with precipitation (R 2 range from 0.52-0.85, with P-value = 0.00). This result suggests that more concerning and applying suitable management for reducing the negative impact of Acacia plantation at the headwater of Vietnam is necessary.
